    Variable frame rate video with Premiere Pro

    rmshro0 Level 1

      Variable frame rate video comes from many places these days: phones, live streamed video recordings.

       

      Adobe Premiere is a supposedly production level piece of software that cost a good chunk of change.

       

      How is it 2012 and Adobe does not still have an answer to this problem?  After trying to editing/convert/mux/edit variable frame rate videos for the past 5 hours I am just exhausted.  No amount of conversion apps, etc have saved us and THEY SHOULD NOT HAVE TOO.

       

      We have spent thousands on Adobe software packages over the last decade, probably 10s of thousands, and the only answer I find consistently is to switch to Vegas.

       

      Surely, SURELY someone at Adobe with real insight into the issue can help answer the question of whether users moving into different medium should find a place elsewhere in the software ecosystem...

          What is the frame rate you want to use and what for?

            The file I am trying to edit was recorded in a streaming application called XSplit, very popular in the game / live streaming community. 

             

            The frame rate is variable, slightly I am guessing, because the real time nature of the recording/stream.  The issue is that while WMP and VLC play the file back 100% correctly, when played back inside Premiere CS6 the file drifts out of sync so at the end of a 2 hour clip, we are talking more than a full second or so.

              Variable frame rates in video are not normal.  It is not used in any kind of professional production environment, which is the market PP is geared towards.

              • 4. Re: How is it possible Premiere still cannot handle variable frame rate video?
                rmshro0 Level 1

                Maybe, but I cannot tell you how much I LOATHE this answer I see all the time from people on this and other professional boards.  I am in a "professional production environment" and we are using "professional" software. 

                 

                I realize it's not 'normal' but keep in mind that the iPhone, the most popular camera in the US today, records video at a variable frame rate and that Premiere Pro, one of the most popular pieces of software still can't properly handle it and keep in sync.

                 

                I don't understand how software like VLC and WMP can playback the file just fine but the minds at Adobe can't figure out a way for us to this video in our projects.  It just boggles my mind.

                 

                There has to be an answer!

                  There is.  Get your video from a real video camera, not a phone.

                   

                  If you insist on using consumer hardware to record video, there are plenty of consumer level applications out there that will probably work better than PP for the task.

                    While I appreciate your replies, you aren't helping at all.  We use a mix of harware in our studio including consumer level camcorders, higher end devices like the 7D and 5D Mark II and sometimes we record live events as well. 

                     

                    Telling a customer to "use better hardware you unprofessional loser" is about as professional as you seem to think I am.

                     

                    I am looking for solutions, and actual answers as to why Adobe continues to NOT support this kind of workflow while their competition DOES.

                      Playing and editing are not at all the same

                       

                      If you need to edit from an iphone, you probably need to use Apple software

                        Hardly what I said or meant.  If you want your video to work with PP, then you need to use compatible hardware to capture that video.  With the current version of PP, that does sometimes leave out some consumer level hardware.  The solution, then, is to not use that hardware if you wish to use PP.  If using that hardware is the larger priority, then you may need to find other software to edit with.

                         

                        As to why Adobe doesn't yet support it, it's more than likely because not enough of PP's market base uses it to make adding support worth the investment of limited resources.

                          Yes, let's remove the "professional" "unprofessional" issues from the equation. The bottom line is that Premiere (any adobe apps?) does not handle variable frame rate at this time. We rarely get any glimpses of why adobe management pursues some feature requests and abandons others. We are fairly confident it is related to the financial bottom line.

                           

                          Feature request form.

                           

                          What major editing platforms provide support for variable framerate? Curious.

                           

                          I'll also say that conversion tools have been very important to many segments of the editing community as various HD and compression methods have appeared and become more popular (or not).

                            Currently I know 100% that Sony Vegas will handle real time editing of these files without issues but our people are simply not trained on it and I have invested quite a bit in the Adobe ecosystem as it stands.

                             

                            We have used conversion apps in the past yes and it can SOMETIMES fix it by stabilizing the frame rate but other times the problem remains - this happened to be one of those days.  Also, that can add 30-50 minutes of transcode time per file to the workflow which can be damning in the world of real-time video.

                              That is indeed one of the fixes we have tried in the past, but on this particular instance the simple transcode (which is what the Quicktime Saving thing actually does) didn't fix it.

                                Is there an alternative to X Split that might produce a more Premiere friendly file?

                                 

                                If some files do work when transcoded (fixed) and others dont...how can you blame Adobe for that?

                                 

                                If the editing  of these file is so important in your studio environment and business..why would you not train your people in an application that fully meets your needs. eg Vegas if thats the case as you say it does 100%. 

                                 

                                They are only tools....and choosing the right one for the job would be seemingly logical and productive.

                                 

                                Maybe down the track ...Premiere will be able to do what you want.

                                      Actually the files we are trying to edit come from Xsplit, not anything Apple.

                                        Both the major programs for game streaming and live stream, Xsplit and Wirecast, record files that are variable frame rates.  Both have the same problem as we have tried both applications.

                                         

                                        The reason we are using Adobe still is that we have been using PP for many years BEFORE doing live streaming was part of our portfolio.  We still do other video projects including commercials using DSLRs for video and I'd rather not have to move away from what we have invested (in time and software) on Adobe.

                                          I took a look at what XSplit is and does.

                                           

                                          Where does the need arise for Premiere with the files that come from XSplit?

                                           

                                          Xsplit seems to be a self contained "live broadcaster" of media compiled within it self.  THen it streams to various "web broadcasters".

                                           

                                          Asumeably it keeps (records)  a copy of what it is streaming?  What do you need Premiere for?

                                           

                                          Just curious about this.

                                              I took a look at what XSplit is and does.

                                               

                                              Where does the need arise for Premiere with the files that come from XSplit?

                                               

                                              Xsplit seems to be a self contained "live broadcaster" of media compiled within it self.  THen it streams to various "web broadcasters".

                                               

                                              Asumeably it keeps (records)  a copy of what it is streaming?  What do you need Premiere for?

                                               

                                              Just curious about this.

                                              After the live broadcast we take the recorded file and edit it for time and offer it on demand.

                                                ...played back inside Premiere CS6 the file drifts out of sync so at the end of a 2 hour clip, we are talking more than a full second or so.

                                                Is that the only issue?

                                                  They are only tools....and choosing the right one for the job would be seemingly logical and productive.

                                                   

                                                  That was the point I was making.  Well said.

                                                      I wonder what would happen if you tried "Interpret Footage" - Speed -  function on the clip.

                                                        I have tried that.  I can 'massage' the out of sync issues a bit but it still goes one way or the other.  Mapping a variable frame rate to a static one just continues to cause problems.

                                                          Let's flip this around. My question is: "How is it possible that these non-videocam devices still cannot produce constant frame rate video?" Why do people use such low quality capture devices and expect PPro to bail them out?

                                                           

                                                          I can see Adobe maybe adding some transcoding features into, say, Prelude to transcode non-conforming video into something usable by PPro, as part of the process of handing it off to PPro. But adding this to PPro, which already supports the vast majority of video standards, is just piling on.

                                                            Fair enough, but argument there would be that while Xsplit is $30, Premiere Pro is...much more.    Also, this program is not the only that records in variable frame rate, sometimes by necessity.  I mentioned above that recent iPhones will often dip into variable frame rates in low light.  And if a user can't know for sure if its variable or static, I just think software should make good faith efforts to plan for it.  Obviously Sony's Vegas has done so.

                                                             

                                                            I'm not saying something couldn't be done on both ends.

                                                              I am having a similar issue, however from what i can tell it is 'constant' rate, not variable.

                                                               

                                                              I am transfering old footage from a HI-8 tape deck. I am using the Sony DV200. It is connected via firewire to PC.  Using PP CS6 to capture. During capture audio is in sync, however when it is done and imports into PP timeline (or even before) it does drift out of sync.  As others have noted, in Windows Media or VLC it plays fine. It is 'only'when within PP.  I cannot figure this out and manually finding the out of sync point and correcting is unnacceptable. 

                                                               

                                                              the fact that other players don't exhibit the issue is perplexing.  The fact that i am capturing it from PP and using it within PP and PP is the one with the issue is also perplexing.

                                                               

                                                              Again, i dn't believe this is a variable frame rate issue, as i used Mediainfo and it shows constant.

Your keyint-min is set to 25 yet wouldn't 30 be more appropriate?

If you are way past this, my apologies, and I wish you luck.

I have to ask if there is a reason you chose 44.1 instead of 48K.

Or just a few? The reason I ask is that I vaguely recall that when a long GOP is cut, Premiere Pro has some calculating to do, and it might keep the drifting down to a minimum. You might try making a lot of extra cuts (after all else is said and done but before exporting) just to test out the idea. I could be wrong on that or it could be a problem fixed long ago.

                                                                        I spoke with adobe support and they lead me to a program for HDV capture, but that wasn't compatible .. so somehow i googled and found this program.. winDV.  it is a VERY small program that simply captures the DV Stream.  well after much testing.. IT WORKS. so you know what... i will just capture my video in this program.  DV Capture is just capturing the digital stream to the .avi... so it really doesn't matter what program is used to capture... and this doesn't seem to produce any issues when i drop the file into premier or encore for editing/authoring.

The only fix seems to be to re-encode the source video with a fixed framerate (and often 100% of them as keyframes). This makes a 1GB video file into 50 or 100 GB sometimes. Frustrating!

Video games are a mulit-BILLION dollar industry and generates an INSTANT user base for streamers and YouTubers WAY faster than any indie "film" production (all marketing aside). And to say video from any source is not worthy to be used unless it's from a "REAL" camera.. well you sir are then NO artist.. and are not helping the creative process. Great movies have been made with JUST iphones and ipads... if you don't belive go to some indie feastivals or simply YouTube it. People can do amazing things with the little they have, and the mentallity that "OH well you just need to spend more money on machinery to be worth a damn" is utter BS. I know this post is old but I was SOOOO fercious when I read it and how a "MVP" responded and no one said anything that I will say something now.

If moderators here do no stand up for their members with legitimate concerns who are snobbishly abused by other members then Adobe PR is not doing a good job concerning this forum.

                                                                                It's easy to notice that I had no personal involvement in this thread up until now and next to no other activity in this forum should suggest a very clear picture that there is something very wrong with the situation. But thank you for addressing the issue with whom I had a complaint with as I see his reply he made suggesting that adobe doesn't care about "teenagers" was deleted. It is incredibly ignorant for someone to say video gaming is only limited to teenagers. As any market research will show that the assumption/statement is entirely incorrect. Let alone saying that Adobe products "should not support" variable frame rates on imported files instead of offering viable workaround solutions to the OP.

                                                                                 

                                                                                To the OP and others with the same issue.

                                                                                If you are dealing with variable frame rates in FLV files (typical stream format of live streaming services) you can save your streamed files locally and use a program called FLV_Extract which will extract 3 files (audio, video, and log) from your FLVs.. from there you can use Yamb (make sure to download MP4Box as well and place in the correct Yamb subdir) to combine the FLV contents into an Adobe supported MP4 or alternative with NO transcoding. This will ensure that you don't loss any data or suffer any quality loss (keep in mind you may still loss quality for final render). If there's is audio synce issues and you are using only cuts of the whole stream then simply unllink the audio from the video and slide the audio left or right to adjust for the sync issue. If you wish to use the whole stream and audio lag fluxuates then it will be very hard to adjust but is still possible.

                                                                                From whta I notice using Quicktime Pro to render out a a CFR version not only degrades quality from re-encoding BUT tends to waste a ton of resources (CPU time) and that time can be better spent in your project timeline and final render.

                                                                                So with live streams, when there's a huge frame rate drops (imo over 5 frames up to 8 is moderate but 10 or over is very notice-able) I just don't use those areas and slide my audio track back into sync. It's not perfect... but atleast there's no transcoding for import and at least some of the stream is still use-able.

                                                                                Good luck!
