    Premiere Pro CC Flickers after render--- client not happy

    matthewd35 Level 1

      Hello I have been having a very annoying issue with Premiere pro CC 2014 (with the most recent update released in November, it also happened before the update). 

       

      Certain portions of my video will flicker, but it only shows up after the render.  I can watch the video just fine in a sequence and it does not flicker.

      I try re-rendering the project and the flicker will appear in a different portion of the video instead.  It is so random and I feel I have no control or ability to fix it

       

      I have provided a video link to show the problem I am having.  This video is from different projects filmed in different lighting and scenarios, and different cameras. All of them have it.  The only thing they all have in common is that i used the RGB curves to bring up the blacks and adjust highlights.

       

      Adobe Flicker on Vimeo

       

      The footage was shot on the Panasonic GH3 and the Panasonic HMC150.  All filmed in 24ps.  I also am outputting the video in 24fps.  The examples in the video I have shown have all been saved in different formats such as h.264 for web, h.264 Blu-ray, and mpeg2-Bluray. It seems that the format does not make a difference it flickers either way.

      It is also not lighting as it even happens outside in the sunlight, and if it were light flickering I would experience the issue on my camera while filming or at least see it during editing.  But it only appears after I render. 

       

      I render using the graphics card Cuda engine 

       

      Here are my computer specs

       

      Windows 8

      Intel I7 processor

      Nvidia Geforce GTX 750 ti

      8 GB ram

          Just in case this is a display card driver issue, can you try rendering a sample in software mode once? Definitely seeing the flicker on the Vimeo sample

           

          Thanks

            You need to do a careful process of elimination by conducting an experiment.  That is, take a troubled sample of your edit into a new project and experiment with the following:

             

            Render just the raw clip without any effects applied to your 24p setting -if it still flickers, that will rule out whatever FX you've already applied in the problem project.

             

            Try rendering again with usual settings and this time turn "frame blending" on.

             

            Try adjusting the Anti-flicker filter under the motion settings in the effects panel.

             

            Try rendering out it to 29.97 from 29.97 sequence.

             

            Apply the broadcast color filter, set to reduce luminance, and limit IRE to 100.

             

            Turn off hardware acceleration and render in software.

              What are your export settings?

               

              Any third party FX applied to sequences?

                No just the RGB curves that is in Premiere Pro

                  Okay so I tried rendering one of the small clips again, I made absolutely no changes and it rendered out just fine no more flicker.

                   

                  This is fine for small clips (20 seconds)  but the issue is different for a larger video.

                   

                  If I render a large video a second time the flicker will disappear from where it was originally, but then show up in a new spot that it was not in before!

                  It is a huge time waster to continually re-render all the time and hope it disappears. 

                   

                  Safeharbor suggested to render software only, which I have done and still no different. 

                  I just recently got the new video card, in the video example I posted, some of the clips were rendered software only and others were with the video card.

                   

                  My export settings are Adobes preset ones for youtube HD or for Bluray export, I don't mess around with the bit rate or anything else.

                    That is puzzling and that flicker is awful.

                     

                    I have been exporting loads of H.264 ( basically Youtube presets) all week with none of that showing.

                     

                    Wish I could advise.

                      You say the flicker is random? That it only works on long clips, (short clips are not an issue).  That sounds like a hardware or some latency conflict outside the editor.  Run a latency checker such as DPC Latency Checker.  Latency issues will show up as abnormal spikes or hiccups.  If you have them, see if the periodicity matches the same as with the video (i.e. X cylces per second, etc).  Latency means conflicts either with poorly written drivers or resource conflicts (IRQ).

                       

                      Are you using any third party capture cards?  If you have a raid card is it on the fastest lane?  Check for resource/IRQ conflicts, (http://www.helpwithpcs.com/upgrading/change-irq-settings.htm).  Open the device manager and change the view "resources by connection".  Twirl down the IRQ list to see what hardware components are sharing the same IRQ.  Specifically what your Raid (if you are using one) and the Graphics card are sharing with interrupts with.  Windows automatically assigns IRQs and sometimes you'll get a conflict where to heavy hitters have to share the same channel and conflict.  IRQs can be manually reassigned via the BIOS (but you better know what your doing).

                        Wow okay I will give that a go. I would have never thought of that and I am not totally sure if I know how to do what you have described but I will try.

                         

                        I do have my hard drives mirrored but not using a RAID.  I just use the windows 8 mirror drive option (which I am told is crap).  Both drives are the exact same brand name and size they are inside my tower connected through e-sata.  I purchase them together and then mirror them.

                        • 9. Re: Premiere Pro CC Flickers after render--- client not happy

                          Mirrored means that both drives are working together on the same files, but one is copying the other.  That's actually slower and not really the best option for editing.  Do you have your system on those drives, or is on a third drive, using a different buss?

                           

                          Raid 0 (stripped volume) is much quicker and can be done via software in windows.  However, you'll lose all your data is one drive fails and should only be used for video.  Install your system onto a separate drive.

                           

                          I use a RAID 10, which is both stripped and mirror.  It's four drives set up as two raid 0, where raid one copies the other.  Should one drive fail, I have a copy of the data on the other to recover from.  I have those on an LSI MegaRaid card, and with 6 GB data-rate, I have plenty of head-room for fast disk speeds.  (However, I do have two old Dells that still use a 2 drive RAID 0 via windows, and have not experienced any failures).  I tend to replace the drives after three-years of constant use to head off any failures.  I never fill them past the 50% mark, and always archive finished projects to an external drive.

                           

                          When I built my latest machine, I ran into a hardware conflict with an AJA capture card.  I looked up the mobo spec and found both slots shared the same resources, so I move the card to another slot to correct it.  I also had issue with a sound card sharing IRQ with the USB ports.  Every time I plugged a drive into the USB port, I would experience audio glitches.  I solved that by disabling the card and using a USB Mixer that came with its own ASIO drivers.  In that case, I simply rolled with it (as disabling the USB was not an option for obvious reasons).  Think of your PC as a busy highway with lots of intersections and ramps, and the DATA as the vehicles.  You want to keep the fast devices in the fast lane and out of congested traffic.  Does that make sense?

                           

                          If you do change your hard drive/raid configuration, copy your data to a storage drive first.

                           

                          To recap:  At the very least, install your system onto a separate drive.  Use another drive just for video, and make sure that video drive is not sharing resources with slower devices.  If you want something faster, then use two drives for video in software RAID 0.  Still faster, use a dedicated RAID card to control them.

                            Thanks for all your insight!

                             

                            I have a separate drive for my operating system and just personal local files.

                             

                            I then have 4 other hard drives, but 2 of them mirror each other.  I am a wedding videographer and we typically fill up 2tb over a summer wedding season.  I hold everyones footage for at least a year, so I end up getting new drives every 4-5 months, they don't really have a chance to get old. 

                             

                            2 of my drives are in my tower.. but the other 2 are connected via an external docking station connected through a usb 3 connection.  I imagine that is not the best to have 2 drives running through 1 usb connection.  As you said it is like a highway and that sounds congested!

                              I can only say that Local internal drives properly configured have always worked for me.

                               

                              I have tried the external docking station with my laptop on location recently.

                               

                              The experience was not as smooth and efficient as my desktop system!

                               

                              I even split it out to multiple USB 3 connections.

                               

                              Nothing beats my internal SATA set up.

                                +1 with shooternz.  USB is unable to run for long periods with issue.  If you require external drives due to lack of space in the tower or want something portable, I suggest you get an eSATA pci card use an external eSATA box.  I've been using ICY Docks (the bento EZ-Tray) for about 4 years now.  They are hot swappable and might be a good fit you.  This is how I cart projects from home to studio and in the field.  I use an eSATA PCMCIA card for the laptop.  One drive suites cuts only and light editing.  They also sell multi-drive bays that you use as a RAID, but I've done the same using two Docks and stripping via software -just don't remove the drives while active and label them as to which dock they belong.

                                 

                                Best that you get your system in order, take USB out of the equation before you revisit this issue.

                                  Hi Matthew

                                   

                                  I'm a total newbie to video shooting and editing, and having exactly the same problems as you. Most of the expert advice above is way over my head, so I was wondering if you managed to find a solution and if so, what it was?

                                   

                                  It seems from posts on other forums this problem is widespread, and may have something to do with adding effects to the clips. I plan to conduct some experiments - render out without effects etc - to try to get to the bottom of it. But no-one I've encountered online has been able to resolve the issue.

                                   

                                  I'm working from an internal hard drive with plenty of room, and loads of RAM on my machine. The problem only occurs with large files off my Panasonic Lumix GH4, with clips downscaled from 4K to 1080p. I'm not having any issues rendering clips shot on a GoPro 3+ , with effects added. Nor with clips off my iPhone - only the GH4.

                                   

                                  Any suggestions gratefully received.

                                    Hey Dabram

                                     

                                    The problem seems to be happening less for me now.. I don't have a clear solution for it. 

                                     

                                    Now before I do a final render, I will pre render all the footage in the timeline.   For me the only time i have the footage flicker is when I add an effect, It never does it on just straight footage.  After the footage is pre-rendered I will then watch through to see if there is any flicker. If there is then I go to the effect and just make a tiny tiny adjustment to something.  That seems to get rid of the flicker.

                                     

                                    I then render out the final video.  Watch again, if there is flicker.   Then I go back to that spot in the timeline and make a tiny tiny adjustment, and render it out again.

                                     

                                    It is totally unacceptable that I have to do this, and is a big time waster when I have a schedule to meet.  I would appreciate if Adobe would fix this.

                                      Hi Matthew

                                       

                                      Since I made this post, I managed to talk to someone in Adobe tech support about this flickering problem, and, predictably, they suggested the root of the issue was lack of processing power in my computer (even though its specs fall well within the minimum cited fr Premiere Pro CC).

                                       

                                      When I made further enquiries, my machine does indeed look well under spec for editing 4k video, and adding effects demands a lot more processing power. It's certainly very slow at every stage, from browsing media to playback and rendering, and can't draw on CPU Acceleration. And I don't think merely adding a bigger graphics card is the answer, as the processor needs to be beefier too.

                                       

                                      There's no way of knowing without spending the money (a lot of it) to upgrade to a machine that's optimized for the job, but my guess is that Adobe are right. Why? Because the problems only occur when I'm using my Lumix GH4 camera, which shoots at 4k. Clips off other cameras render out cleanly with effects (albeit slowly).

                                        Hmmm okay, I am editing my GH3 footage which is not 4k.  But my computer is more than capable of handling 1080p footage.

                                         

                                        I will have to keep searching i suppose

                                          I have a similar issue with video flickering but it caused by applying an effect on an ajustment layer. If I apply the effect directly to each piece of video there is no flickering.

                                            Interesting. So I can rule out 4K as the cause? Maybe not. Who knows. But yes, it's all very frustrating Adobe!.

                                             

                                            Computer specialists I've consulted on this all say the same thing: to run the latest version of Premiere Pro CC smoothly, adding effects to clips, you need a top spec machine with lots of RAM (minimum 16GB), an Nvidia Geforce 970 card or comparable, and one of the most recent generations of processors, (to enable CPU acceleration).

                                             

                                            The guy at Adobe as good as admitted this. Basically, the "minimum specifications" listed on their website are years out of date and wildly optimistic. Sure, if you just want to edit, and wait for ages for your clips to pre-render so they can be played back smoothly, then less powerful computers are fine. But once you start adding effects, the processing power required is immense - and significantly, this kind of work is being done by the processor not the graphics card.

                                             

                                            I'm going to experiment with a high-spec machine and see if it resolves the problem.

                                                We believe that this is fixed in an upcoming version of Premiere Pro. Sorry for the inconvenience. Certain color correction effects can cause the issue, especially when applied to Adjustment Layers, but can even occur when directly applied to clips. Other things in common are NVIDIA GPUs and Windows OS.

                                                 

                                                Some of the effects include Three-Way Color Corrector, Curves, Unsharp Mask, and Brightness and Contrast.

                                                 

                                                Thanks,

                                                Kevin

                                                    Hi All,

                                                    After much frustration with exports flickering and 'bleeding' into 2nd layer, I've now come to the conclusion - without any doubt -  that the problem lies with CC 2014 and NOT with any filters, system, system settings etc. etc.

                                                    Reason:

                                                    I upgraded  from CS6 to  CC 2014 to be able to export in DnxHD as per Broadcaster's requirements.(South-Africa). Exports in CC 2014 are totally unexceptable for broadcast purposes. I loaded a previous version (CC 2013) and imported sequences from CS6 (I am one of the lucky ones that still had the projects in CS6 - CC 2014 projects won't open in CC 2013!) re-did changes on sequences done in CC 2014 and exported in DnxHD - PERFECT.

                                                    NB. all sequences had same filters as CC2014 sequences and NO changes in system.

                                                    I'm no an  IT person, but have been editing for 38 years - yes, started on film and Steenbecks - I would like to suggest that the people that develope the software -  and market it as professional software - go back to CC 2013 and start by adding one bug-fix at a time and after each one, make it available to the consumer to actually test it for defects, before proceding to next bug-fix.

                                                    My humble opinion.

                                                    Thanks

                                                        For any effect you add to the video that causes this, in my tests at any rate, the option Temporal Smoothing should be available. Crank it up to a value of 10.00 and that should fix the flickering. You won't notice any change without rendering and playing the video within the timeline, or exporting the video.

                                                          This is worth a try - it worked for me!  I had the same problem with mysterious flickering on output from Premiere Pro for certain effects such as ultra key, color correction, etc.   It looked perfect in PP while I was in the program itself just previewing it but always generated flickering when I rendered it.  The work-flow is that you do all your work in Premiere like normal (including dynamic links to AE if needed)  but do your rendering via AE.  Once you are done with your work in PP, then save the file and close PP.  Open AE creating a new blank, empty file, Import the PP file/sequence into AE, create a composition out of this sequence and render it in AE (you can hand it off to Media Encoder from AE).

                                                           

                                                          OK, here are the steps:

                                                           

                                                          1. Create your sequence in PP, preview it to make sure it is correct, but don't render it via PP

                                                          2. Close Premiere Pro

                                                          3. Open After Effects, creating a new blank, empty file.   Import the Premiere Pro file.  From the pop-up window select only the sequence that you want to render.  In AE, drag this sequence down to create a simple composition.

                                                          4. Render this composition from AE.  You can hand it off to Adobe Media Encoder.

                                                           

                                                          That's it!  Hope it works for you.  It definitely worked for me and solved this maddening problem with PP not being able to render effects, ultra key, and other special effects correctly without flickering.  Just do all your work in PP (including dynamic links to AE), save the PP file, Import that file/sequence in AE and render this composition from AE.  I also didn't notice any longer render time via AE verses via PP.

                                                            Hi,

                                                             

                                                            I have the same flickering problem after trying to render effects in Premiere, be it applied on adjustment layers or directly on clips. I'm using Premiere CC2015, latest update.

                                                            I noticed that the flickering goes away after deselecting Mercury Playback Engine GPU acceleration (OpenCL)" and selecting "Mercury Playback Engine Software Only", in the Project Settings. However, rendering becomes slower and some keyframes commanding Mask Opacity simply don't work. I suspect other things might work properly too... Any better idea to eliminate this problem?

At my wits end here, been browsing forums and web for MONTHS and still can't seem to find a fix.  I tried the suggestions listed here and none worked for me.  I can't believe a problem this large has been ignored by Adobe, what a joke.

                                                                Hi NateP,

                                                                Almost a year since this post and still not fixed.

                                                                 

                                                                I'm not experiencing this issue. Have you filed a bug yet? If not, please do so. I find that nesting a clip and then adding an adjustment layer to the nest can sometimes help work around the issue. This changes the order of render operations that can cause edge flicker. Can you try that?

                                                                 

                                                                Also, I would avoid any of the effects in the "Adjust" category. These tend to cause this issue.

                                                                  As a possible approach ... and understand, I've never had the flickering, nor is it a common problem for most users ... you might need to re-think your color-modification/correction workflow. I think Kevin's comments about the "adjust" section being a possible cause of the problem is likely to be a large part of it. I would suggest using the color workspace Lumetri panel as several colorists have studied it, testing it with ramps and such, and decided the color science is far "cleaner" and more reliable there than with the "legacy" color correction tools. At least, use that as a base, adding other tools only for specific needs you can't easily do (or at all) within the Lumetri panel.

                                                                    No problem when it's played in the timeline, so I exported twice - once with subs, another without. The one with subs flickers, whereas the other doesn't. I'm using Mac OSX 10.11.4, and Premiere Pro CC2015.3. Has anyone experienced this, and/or know how to fix this?

                                                                          Alas,

                                                                          the flicker is still there.

                                                                          Do you think it has to do with using the Legacy Title tool? Adding that title is when it started.

                                                                          I have a lot of work to do and don't have time to fuss with the new version. I tried but it is not useful to me at all.

                                                                          Going forward I will just create the titles in After Effects.

                                                                          But, the problem is that the flickering won't go away. Even the green screen is flickering which didn't happen until I added the title.

                                                                          • 34. Re: Premiere Pro CC Flickers after render--- client not happy

Past trying to manually update or perhaps even roll back a video driver, and of course, using the Adobe CC Cleaner Tool to obliterate PrPro & reload, I'm ... out of ideas.

                                                                              I'll keep trying.

Do you have any idea why the green screen was working fine before and now no? Maybe a glitch with the title tool on top of a green screen?

                                                                                I didn't have this issue when I sued cs6. However now that I use the latest version of Premiere Pro cc I'm having this very same issue. It's bugging me out that an earlier version didn't give me this much trouble. Is there a fix for this issue??

                                                                                • 38. Re: Premiere Pro CC Flickers after render--- client not happy
