    Premiere on a SAN, lag issues

    RyanScottJones

      Greetings!

       

      I'm a video editor and motion graphics artist for a corporate company that just purchased a NexGen SAN system (it was a great deal price wise). It's basically a RAID of SSD's with a RAID of regular hard drives for long term storage. When files are used frequently, they are copied to the SSD's. My HP Z400 has a Fiber 10Gbps PCIe card installed and I.T. used a software package called metaSAN (Tiger Technology) to monitor the system (the drive is mounted as a letter drive). When I'd copy my Premiere and After Effects projects over, not only would I get horrible playback with uncompressed footage, but the lag for scrolling through my files was terrible. However, I could load each QuickTime uncompressed file in QuickTime player and it plays back 100% smooth. Only in Premiere it stutters.

       

      I.T. eventually returned the metaSAN software due to backup software incompatibility. Now the SAN drive is just mounted via the same letter drive. Not only is playback worse, but I locks up Premiere when I hit play. When I load QuickTime files vis the QuickTime player, the files play back terrible.  I've tried several combinations of cache locally, cache on the SAN, Premiere project on the SAN, Premiere Project locally. Basically, I'm back to editing 100% with my GSpeed RAID10 drive.

       

      I've read a lot on Premiere and it's problems with XSAN, but I haven't found anything on a regular SAN. Why would this happen? I.T. is 100% Windows based and everything is on a domain (I did do a test with my computer off the domain and same issue).

       

      Is there a workaround or a fix?

          I don't know if any of this will give you any direct help, but I have some saved links from previous discussions

           

          No current version of Premiere works properly, if at all, over a network

          -you may NOT "map" your My Documents folder to a network drive

          -you MUST give all users administrator accounts to use Premiere

            Hey John, I was actually just reading those links about an hour ago. I'm not sure what I.T is using as far as Windows Server. But I do know their entire network and domain talks to PCs only. Out graphics designers are all on Macs and they have an awful time with mapped drives via a regular ethernet connection. I'm trying to get a MacPro for my workstation (I'm edited on Macs for 9 years and I'm on a PC.)

             

            I'm not an admin on my computer and I probably won't be due to "regulations." Our I.T department didn't research the nexGen SAN hardware before purchasing it, just that it "would work with our systems." I've seen Adobe, Final Cut and Avid SAN's that work, but they are twice the cost of their current purchase.

             

            Thank you for your answer and links!

              >not an admin on my computer

               

              That is a real problem, since PPro and Encore must be run with an Admin account (at least in the Win world, I don't know about Mac)

               

              Not only must you be using an Admin account, Encore has a further requirement http://forums.adobe.com/thread/969395

                Funny you say that. I just had my Encore grated Admin access to burn a DVD on my work PC. I'll get I.T. to grant myself admin on Premiere. I'm not sure if that will fix the SAN issue, but it's another checkmark off the troubleshoot.

                  Sorry for the delay, but I was granted admin access for the entire Adobe folder. It still lags. Are there settings in the Local Area Connection for the fiber? I saw settings for packets, etc. I'm wondering if settings need to be calibrated.

                    Can you copy the files and work locally? As John mentioned, working in a SAN with shared media is currently not supported.

                      Well I do that already. I keep everything on my G-speed drive RAID10 and edit via eSATA. My problem is, IT purchased a $$,$$$ SAN network with Fiber support. They want us to use it as a central location so any editor can pull a project from his/her computer in their own office with no relinking issues. Since IT doesn't know anything about Abobe, they jumped the gun and bought the system anyway due to the increadibly low price. A REAL system would have run them 3-4 times the cost and would support Avid, FCP and Premiere. This is just storage and it "should be super fast." Should, isn't good enough for me however.

                       

                      I'm trying to be supportive to IT and explain that Adobe may or may not support a SAN environment. So, I'm trying to fish for facts on why it doesn't work vs "it doesn't work." Make sense? Rather than saying "You didn't do your homework."

                       

                      If it doesn't work on my PC, then it won't work on a Mac either. It will just be a fast way to copy files back and forth, which will look bad after spending that kind of money.

                          It's one thing to have users be able to bring up a project after you are through it (network storage). It's another if you are working on the same media at the same time as other editors (SAN).

                            LOL @Jim. Well, when I try to play an Animation Codec MOV file from the SAN in QuickTime, it's more choppy than Premiere. If it doesn't work, then it doesn't work.

                             

                            @Kevin, I hear ya! It's not so much editinf from the same footage, it's more or less a project that anyone can access if the owner is busy with something else. Sometimes we shoot 100GB of footage in a span of three days and two of us need to cut to gether a Recap video and a promotional video. So rather than spending time and space copying the 100GB to each G-Speed, it would be nice to have it in a central location.

                             

                            But again, if Premiere doesn't support it, then it's editing local. After Effect is a little faster, but the scrolling through the files is a lot slower (response time wise) than if they are all on a local drive.

                              Scott, what is the data rate of the system?

                              • 12. Re: Premiere on a SAN, lag issues

                                I'm not sure which system you are referring to, but here is the facts:

                                 

                                My workstation is a HP z400 with a 10Gbps Fiber card. Their system is a NexGen (http://www.nexgenstorage.com/) file server. It's something like a 6 SSD RAID0 connecting with 12 HD RAID10 (or something). So the more files we use frequently are copied to the SSD RAID. The stuff that's archived from years ago will remain on the HD RAID. The system will identify duplicate files and reference them, thus deleting any copies.

                                 

                                The files I'm using are Animation Codec (around 1Gbps data rates). In theory, it should work as we have 10Gbps cap. We did copy tests and Task Manager kicked up the % to 25-50% of the SAN network.

                                  OK, it sounds like a bottleneck in your system--a system component, the media you are using, or a combo of both. You are working with Animation codec files? That would indicate a good source of a bottleneck. Animation codec files should really only be used for high end, lossless graphics or animations. It is overkill for standard video editing. Can you try the camera's native codec?

                                    Well on my Mac at home, I use ProResHQ for everything After Effects. Here (using Windows 7), I render everything out as Animation Codec for Premiere. So I used footage plus my animation builds from After Effects in Premiere. We shoot on the EX3 so bitrates are fine.

                                     

                                    I can edit Animation Codec all day long on my GSpeed RAID10.

                                      Of course, you cannot expect the same performance with Animation files on a dedicated RAID vs. a SAN. Although you can playback an Animation codec just fine on your GSPEED, it's not an optimal workflow for taking it to the SAN. Furthermore, every editor I know render out AE comps in a codec more friendly for editing (ProRes for Mac/DNxHD for PC) and never place an Animation codec file in a Timeline. Since ProRes 4444 came out, I have not even found a good use for the Animation codec on the Mac. On the PC side, definitely look into the free DNxHD codecs. They are much more lightweight and will serve your workflow much better, and with high quality. This will cure much of your "stuttering" problems, I believe.

                                        I miss my ProRes files. I'm trying to get IT to get my a Mac (been on a Mac for almost 10 years) but if they can't get the SAN to work on the Mac, then it's PC all the way.

                                         

                                        I've never edited on a PC so I have no idea what codec to use. I'll download the DNxHD codec (Avid's website, right?) and try that.

                                         

                                        Thank you for your suggestion!

                                          No problem! BTW, you can encode ProRes files on a PC now. Check this out: http://www.cinemartin.com/cinec/

                                           

                                          As a Machead who went to Cupertino High School, lived near Jobs and Woz, worked on the FCP team on 2 versions of Final Cut Studio, I hear you regarding a love for Macs! That said, once you're working in Premiere Pro or After Effects, the OS does not seem to matter to me as much any more. It's just those little gotchas like working with ProRes.

                                              The ProRes did it! Even 4444 plays back smoothly. The only downfall is when Premiere hits a "red line" that needs to be rendered, it goes back to stutering (lower thirds or just a text layer).

                                               

                                              Thank you again for your info!

                                                I'd like to offer (or ask for) some clarifications.

                                                Of course, you cannot expect the same performance with Animation files on a dedicated RAID vs. a SAN.

                                                Who said? Why not? Half the point of a SAN is to bring local-drive performance to the network (the other half is sharing it), and to have comparable performance to a local RAID. Of course, there's a big "it depends" - the SAN has to be optimized, built of sufficiently fast components, avoid excessive load, etc.

                                                Where did you find a lot of reading about Premiere problems with XSAN? I've been researching PPro+XSAN for months and found perhaps 2 threads discussing problems, all other evidence point to it working fine. I'm not talking about sharing projects and media, though. PPro CS6 does not support project sharing and you have to be careful about sharing media. In this regard yes, there are definitely problems, but this thread hasn't been about project and/or media sharing.

                                                 

                                                By the way, we've been using PPro CS6 on a SAN and NAS here at our facility for months. Our Mac Pro clients connect over fiber to an old Avid Unity 4.2, and the projects reside on the NAS. PPro has been working well, in fact being more stable than our Avid bays. We're in preparations to retire the Unity and migrate our facility to PPro+XSAN with the help of a system integrator, although yes, we have to largely give up shared workflows (Adobe Anywhere notwithstanding).

                                                 

                                                 

                                                Speaking of which, I'm also a bit surprised that Kevin recommended sending Adobe SAN support feature requests - as a fairly involved end-user it seems obvious that Adobe is very focused on Adobe Anywhere which will be their answer to shared workflows. I have no expectations from Adobe to offer anything new as far as SAN until they release Anywhere and we assess what it can (and cannot) do.

                                                  They are suposed to be testing their fiber storage on a MacPro (our IT department is anti-Mac). I'm on a PC (HP Z400) right now. I'm not sure what their configuration is, but it's still lagging when editor A is copying files while I'm editing. Something is not configured correctly and I'm running out of ideas.

                                                  I was skimming through more Adobe Forums and someone had mentioned their XSAN not liking CS6.

                                                   

                                                  The point of my asking in this forum is to gather facts on whether or not CS6 works with a SAN. As an editor/motion graphics artist, I'm playing IT to get my workflow working fast. Since our IT department has no idea what Premiere or After Effects are, I'm having to research this problem.  As far as I'm concerned, I'd rather edit from my GSpeed drive...as I know it works.

                                                    Hi Scott!

                                                     

                                                    I have the same problem like You or Your IT-Dept.......working with Adobe Premiere Pro over a central storage

                                                    http://forums.adobe.com/thread/1166877

                                                     

                                                    I will give a try to some tests in the upcoming weeks with some constellations of Hard- & Software.

                                                     

                                                    As I`ve read, You are working on a HP Z400 machine so did You ever try RGS (RemoteGraphicSoftware) from HP itself?

                                                    http://www.hp.com/united-states/campaigns/workstations/remote-graphics-software.html

                                                    If You are working with RGS the HP Z400 is attached directly to the storage and with a thin client You are connecting to the Z400, this is somethin like a performant remote desktop

                                                    http://www.youtube.com/watch?v=28RMuXqRemc

                                                     

                                                    Adobe is working on a solution like RGS and it`s called "Adobe Anywhere" but it`s just known that Adobe will release this in 2013 but no-one knows the releasedate.

                                                      I'll take a look at that and suggest it. To connect to the SAN drive, it's a domain connection. So in other words, we network map the path (\\networkSAN) to D:

                                                       

                                                      So I have two Local Area Connections, one is 100 Mbps the other is the 10Gbps. When I load D: projects, the 10Gbps shows activity.

                                                       

                                                      Is this the correct way to connect a SAN?

                                                        I'd like to offer (or ask for) some clarifications.

                                                        Of course, you cannot expect the same performance with Animation files on a dedicated RAID vs. a SAN.

                                                        Who said? Why not? Half the point of a SAN is to bring local-drive performance to the network (the other half is sharing it), and to have comparable performance to a local RAID. Of course, there's a big "it depends" - the SAN has to be optimized, built of sufficiently fast components, avoid excessive load, etc.

                                                        The point is to not use Animation codec for intermediate use. It's somply not done in today's post environments. As far as data rates go, you can get faster disk speeds on a dedicated RAID over a SAN, which also has to take redundancy into account. SANs can be fast enough for standard video files, but the Animation codec has a very high data rate. Too much for some SAN systems for reliable playback and redundancy.

                                                        Where did you find a lot of reading about Premiere problems with XSAN? I've been researching PPro+XSAN for months and found perhaps 2 threads discussing problems, all other evidence point to it working fine. I'm not talking about sharing projects and media, though. PPro CS6 does not support project sharing and you have to be careful about sharing media. In this regard yes, there are definitely problems, but this thread hasn't been about project and/or media sharing.

                                                        You're right, there's not a lot of info out there, but here's what one of our engineers said:

                                                         

                                                        "The bad news is that our XSan testing has been pretty limited. Most  of the information

                                                        that we know about it has come indirectly from  customers. In short, it works with

                                                        Premiere Pro. I'm certain that  there are some caveats around configuration and usage

                                                        (as there is  with any network storage), but the details of that are largely  unknown.

                                                        The good news is that next week we'll be installing an XSan  in our compatibility lab so

                                                        we'll have much better information about  its use soon. We have some very large

                                                        customers that need to use  their existing XSan storage with Premiere Pro, so we are

                                                        definitely  motivated to make sure it's compatible. So much so, that we intend  to

                                                        demonstrate a Premiere Pro / XSan workflow at IBC this year.


                                                        The bottom line is this - although we don't know much detail about  XSan and Premiere

                                                        Pro integration now, we will shortly and it's our  intention to make certain that it

                                                        works well."

                                                        Speaking of which, I'm also a bit surprised that Kevin recommended sending Adobe SAN support feature requests - as a fairly involved end-user it seems obvious that Adobe is very focused on Adobe Anywhere which will be their answer to shared workflows. I have no expectations from Adobe to offer anything new as far as SAN until they release Anywhere and we assess what it can (and cannot) do.

                                                         

                                                        Of course, I cannot comment on any future products, however, any feature request is valid including traditional SAN workflows.

                                                            The point of my asking in this forum is to gather facts on whether or not CS6 works with a SAN. As an editor/motion graphics artist, I'm playing IT to get my workflow working fast. Since our IT department has no idea what Premiere or After Effects are, I'm having to research this problem. 

                                                             

                                                            Premiere can definitely run on a SAN. The devil is in the details, and there's a million of them. One of the simpler things to do, like Kevin said, is to try abandoning Animation in favor of ProRes4444. If that works for you, great. Another simple option is to avoid the IT dept. hassle and edit off your GSpeed. It may well be that PPro CS6 can work in certain Mac SAN configurations but is doomed on Windows networks.

                                                             

                                                            Many users and editorial departments are in your situation, unfortunately, where they're at the mercy of the IT people. They may be experts on SQL data deduplication but are clueless about video. You need true cooperation and willingness to research and hire the right consultants/integrators if you want a good working system.

                                                              Yeah, I understand about the Animation codec. The only problem is if parts of the edit are unrendered, the GSpeed will keep going vs the SAN will hang and stutter for a few seconds after that point. My system at home is a RAID0 with 4x 1TB drives. I can almost play uncompressed RED footage ... almost

                                                               

                                                              Their NexGen is a PC server, not a MacSan. Everything is PC. They even wanted the entire graphics department to switch to PC as it "talked better" with their servers. That's another story.

                                                               

                                                              I think the best response was "Something is not configured correctly and it's out of my control..." as I think that's the truth.

                                                               

                                                              The reason they purchased this system was for video editing from a central location. This server would house our active projects and they'd be backed up from the SAN. They got a really good deal on the server, hints their purchase before asking us about Premiere, AVID and After Effects.  Again, my point of the forum post was to gather facts to form the conclusion that their purchase MAY not work with us. And it might not.

                                                               

                                                              ProRes worked fine! But the more I edited in After Effects, the worse the laitency got. When I'd scrub through my AE time line, I'd get program lock up for 4-5 seconds. Then I realized that my boss was copying 200GB of footage to the SAN while I was editing in After Effects. When he finished, the laitency went away. <shrugs>

When we use it, it's for its intended purpose - rendering graphics with alpha. I agree that it's a dubious choice as an intermediate video codec.

                                                                Joe beat me to it... I'm very familiar with this comment from Mitch Wood, and as Joe pointed out, it's nearly 2 years old. I wrote to Mitch and never heard back, I'll touch base again with Van Bedient (who's been very helpful) and see if he can help.

                                                                 

                                                                As far as data rates go, you can get faster disk speeds on a dedicated RAID over a SAN, which also has to take redundancy into account. SANs can be fast enough for standard video files, but the Animation codec has a very high data rate. Too much for some SAN systems for reliable playback and redundancy.

                                                                 

                                                                A SAN will be slightly slower than the same storage mounted directly, but you confused the cause. Taking redundancy into account is what RAID does (RAID0 notwithstanding). A RAID5 DAS will be slower than a RAID0 DAS, and conversely, you can run a SAN without redundancy (just look at any Avid Unity SAN with workspace mirroring disabled).

                                                                 

                                                                You're right that some or most SANs are slower than typical latest-generation DAS, but the point I'm trying to make is that it's all in the details. 8Gb fiber is becoming commonplace, and DVS, Hitachi or GVG will gladly build you a (very expensive) SAN that will handle Animation codec as well as multiple streams of uncompressed 4K.

                                                                 

                                                                I don't want people finding this thread and concluding that PPro CS6 + SAN = fail (it doesn't help Adobe sales either ;-) . Premiere is fairly storage-agnostic as far as NLEs go, but networked video storage is complicated. There are many parameters, limitations, and considerations that make the difference between a working and a non-working solution, as Scott has been experiencing.

                                                                 

                                                                I'd like to reinstate that I'm delighted by the communication, cooperation and vibe I've been getting from Adobe nowadays, from staffers in the forums to corporate policy. Better by leaps and bounds than a certain fruit company.

                                                                  I don't want people finding this thread and concluding that PPro CS6 + SAN = fail (it doesn't help Adobe sales either ;-) .

                                                                  Oh don't worry, based on Adobe's rise up from Apple leaving Final Cut Pro and AVID's bye-bye Media Composer, I'd say Adobe still wins. Premiere very well could run from a proper configured SAN, I just think a finely tuned SAN's vs what we have.

                                                                   

                                                                  The IT department said that even though Animation Codec was around 1Gbps, it should run through a 10Gbps port. I mentioned that only a RAID powerful enough to handle a 1Gbps file would determin the speed before the 10Gbps port. Since the NexGen is a RAID of SSD (6 I believe) they said it would playback Animation codec with no issue. When they had the Tiget Software installed (project management software, I don't remember the name), I could play a Animation MOV in Explorer via QuickTime player with no lag. In Premiere, it would lag. Since they uninstalled the Tiger Software and just did a \\sandrive it's back to lag on both. Like I said, when I add effects to my timeline with ProRes (or even EX3 codec at 35Mbps) the second the line turns red from yellow, the system lags big time. The GSpeed doesn't lag, it just skipps frames and continues to play full frame rate when it hits the yellow line. 

                                                                   

                                                                  I honestly think the SAN system and my computer need to be finely tuned to operate. I hope.

                                                                  • 30. Re: Premiere on a SAN, lag issues

There is no real difference in behavior between FCP and Premiere Pro as soon as the volume is mounted.  The must important part of using a NLE on Xsan is the way it should be set up for video post-production. Considerations include:
