After Effects Rendering Random Black Frames

Latest AE Build: 2014.2 Release. i7 Processor - 64 GB Ram - GForce FTW 680 with 4 GB Video RAM.
AE Project coming from Panasonic P2 files, rendering to AVI Cineform results in random black frames.
I have compared two separate renders of the same clip, both have black frames in different spots. Never had the problem with older versions of AE.
Anyone else having this issue or have an answer?
Thanks!
UPDATE: Rendered to QT DNxHD and haven't found a Black frame yet. May be Cineform AVI compatibility issue since the addition of Cineform QT  support maybe? Didn't notice it before that. Hmmm.

Thanks for your reply, Szalam.
Yes, I am very familiar with the bug report process. I wanted to see if anyone else had the same issue hoping that I could find an immediate solution. As it stands, the temporary workaround is to render to something other than Cineform AVI.
Sorry, I am quite busy right now (large project with a short deadline) and don't have the time to do much test rendering. When I get a minute I will definitely do more tests with different codecs etc.
I would be happy to upload some P2 footage when time allows. Is there a way to upload directly to this site, or  is there another preferred method? I haven't attempted uploading files to this forum before.
Thanks again for your help!

  • After effects CS6 random white frames

    I am a hobbyist working on some AE projects using an HP Z820 workstation.  Have opened these projects many times to add to them over the last few months with no issues.  Two days ago opened them to find a few single random white frames.  Isolated the problem frames to Keylight 1.2 and Fast Blur.  In Keylight, when I changed Screen Shrink/Grow to 0, the three white frames went back to normal.  Some other white frames were traced to the Fast Blur effect.  Blurriness was set at 20.  I changed it to any other number and white frames went away.  I left it at 19.  Now here is the kicker!  Today I open up the projects to apply these annoying fixes to some other affected areas and everything is BACK TO NORMAL!  I can use all the original settings!  I suppose I could just be happy it mysteriously resolved itself after a good nights sleep but I don't like unsolved mysteries.  It could happen again!
    Any explanations other than sun spots?

  • Has anyone solved or worked around the After Effects CC red flash frame glitch?

    I can't find any mention on any forums of the After Effects CC red flash frame glitch later than Feb. 2014. I just installed 12.2 (which was my first CC version) on my macpro and started getting the red flash frames randomly, but with increasing frequency, in my projects. I have never had this problem before on any previous computer or version for AE. The forums I've read have referenced ProRes source footage, outputs to ProRes, and lens blur. My project uses all of these things.
    If there is a universally accepted solution/work around, I haven't seen it definitively. Do I not use ProRes source footage? Do I not render to ProRes 4444? Do I not use the lens blur effect? Do I give up and go back to CS6?

    Hi Keith,
    I have the "same" issue with the red frames in AFX CC
    I have seen them first, as I resized a prores4444 HD to a smaller format and saw the redframes in the preview window.
    Setup in AFX: I created a comp from the HD Prores4444 footage and put this comp in a comp with resolution of 960x540.
    The output format was again prores4444.
    I shuttled through the clips in the small comp and I saw the red frames too.
    When I switched to the HD comp at the same position everything was fine.
    I "solved" the problem by flushing the cache, twice. Because after the first purge I was only able to render the first clip. The second one had the red frame problematic again.
    Maybe It has something to do with hardware accelerated layers.
    I'm using a MacPro running OSX 10.8.5 with a Nvidia GTX680.
    Cheers

  • Fcpx Random black frames

    I've been using FCP X to do simple projects until I can master it. We all know it's buggy even on the best macs, but today shocked me.
    Random black frames littered through out the video. Not a lot, but even one black frame ruins the shot. I shoot interviews and b/roll of businesses for a company and then upload the footage, I like to do a little pre edit to organize and delete unnecessary footage in FCP X.
    I've been liking the new tools, the new interface and the way it handles different formats. Yesterday it was freaking out a little on the output, but today I got random black frames on the HD footage and complete video static on a clip in my SD output. It crashed a lot yesterday, that I can understand (kinda), but actual glitches in the output? OMG, that is just wrong. It makes me wonder if any of my other projects I outputted have a similar problem but the client didn't tell me about it.
    Wow, back to FCP 7 till they work this out.
    It's like my IPhone, it's a fantastic device with all these features, but the phone part is worst then my last phone.
    You can have revolutionary video tools in the software, but it had better output perfect video. That's it's main job.
    Anybody else have  problem with black frames?

  • After Effects Ram Preview Drops Frames , Using Strangely Too Much Ram

    System Specs :

         Graphic Card : GTX 770 4GB RAM
         Storage : 256 GB SSD + 2 TB HDD

         Using After Effects CC 12.2.1.5
    NOTE : NOT ANY ADDITIONAL HARDWARE IS ATTACHED TO MY PC . NO SOUND RELATED EQUIPMENT NOR CAPTURE CARD NOR ANY THING ELSE
    Hi there
    As you Already Don't know I'm an After effects Specialist Using it for quite long time . There is an Ancient Problem with CS6 CC versions . I have a short Small size 1080p Video , about 8 MB , I drag it into project panel and then put it into timeline hence it creates a sequence . There are no Effects and nothing added to timeline , just a small simple video . The Strange Problem is when I click "0" for ram preview , The video starts playing and the green bar above timeline starts to fill . When Ram preview Finishes and plays the video from beginning I See there are several frames Between which are not being loaded to Ram ! The video plays RGB color bar instead of main video and when I check the Green bar above Timeline I see that those frames are being dropped and there is no Green bar above them !
    I have had this problem several times before but this time it is too important and the problem should be solved . What is obvious is that some frames are not being rendered or are being deleted after render !
    Another Strange problem is that when I open Task manager , It shows AE uses around 10 GB ! of RAM when I press "0" for Ram previewing this video !
    So there is a Logical explanation here , Somehow when I do ram preview this video it uses extra ordinary too much ram so AE is unable to load the full video (8 MB) into Ram and hence deletes some of frames .
    most of my videos have not this problem and use acceptable amount of ram .I've had this issue with some of my videos till now .
    Listen carefully : "This has nothing to do with AE preferences or low memory or plugins . because there is nothing wrong with any individual components of may hardware or software . I have far more than enough RAM for a 8MB video . My Memory has no hardware or software problem . I tested them and if there was any problem with memory or other hardware that should have affected other applications . I have the most recent AE version . I have the most Recent windows updates and drivers . I have a Clean virus free system , and as a computer engineer this strange AE problem is rarely caused by viruses , trust me . I have not any hardware instead of ones a normal PC has . I have not any problem with my whole entire system configuration because I have benchmarked my PC with several up to date softwares . I have tested my PC with almost any STRESS TESTING solutions available for really long period of time , 3 days by IDA64 . Not any driver conflict , dll missing , registry problem have been discovered , as I know perfectly how to solve them ."
    I asked some of my friend whom are expert in AE . I handed them my videos and Watched ALL OF THEM HAD THE SAME ISSUE ! So the problem isn't related to my Local PC . What i believe is that there is some malfunctioning or miss coded part in AE source code that decides to reserve such a huge strange amount of ram for such a tiny 8MB video . The point is that the AE works fine , no crash or any problem report . So the AE it Self decides to allocate such huge amount of ram and thinks it is correct ! So I think this is a work around that AE developers in adobe are using to bypass a problem or conflict ! by Using more amount of RAM . I think that there might be some miss understanding between the AE and my installed codec . I installed MEGA CODEC PACK on my PC to enable some new codec supports , and so are some of Windows default de/encoders changed to new ones . I think there shouldn't be any problem But there is something wrong between AE and de/encoder modules !
    Please any one with any suggestion , I really appreciate your advices .

    ###UPDATED###
    Well thank you guys for your patience ...
    as you considered I forgot to mention the codec itself and other stuff ...
    The video is in 1080p , 35 sec long , it is a green screen shot , this video is directly downloaded from YouTube and plays perfectly on all tested PCs . here are detailed info :

    NOTICE : This video is just for testing the lighting and etc , and so the Sampling and other specs are not considered for broadcast .
    I think you hit the point ! Thats K-lite codec pack installed on every machine which the video is tested on ! The point is whats wrong with it ?! I have had never ever any problem with this codec pack !!!
    The deadly question : So what are the alternative ways to work with codecs that AE doesn't support ?! because installing codec looks simple and sufficient !

  • After Effects rendering with Format MXF OP1a 1080i/25, XDCAM with colour space "HDTV (Rec. 709) 16-235" but after rendering the colour space is "30-217"

    Hello!
    I have a very annoying problem in After Effects. I'm making an Animation with the format "MXF OP1A, Codec XDCAMHD 50 PAL (4:2:2)" with 8-Bit and with the colour space "HDTV (Rec. 709) 16-235" but after rendering the colour space is not 16-235, it is 30-217 RGB. After I activate the colour space in After Effects, then it shows the right values, but after rendering the value for white is 217 and for black is 30. Hopefully someone can help me. Thanks in advance.
    Bye

    Thanks for your answer, but i don't know an Adobe Media Composer, you surely mean Adobe Media Encoder, or not? Anyway i do not find the option for colour space in Media Encoder, so i would be very thankful if you could tell me where to find it.

    Y'know, for the past few days you've been crying and moaning about slow render times.
    I went back & checked, and do you know how much information you've given to help us help you?  Here's the answer:  ALMOST NOTHING!  And that is despite people asking you over and over again for certain information, and you ignore it!  Do you LIKE not getting help?
    You know what we know?  You're running Win 8 and you have 8 gigs of RAM.  You're rendering a 3-minute clip, and it's taking 10 hours.  Well, lah-dee-dah.  In AE terms, you might just as well have told us you're from Japan and you have red hair.
    You want to know what we should know?  Here's a list that will get the diagnostic process going:
    The PRECISE version of AE you're using, right down to the last decimal place
    The PRECISE version of your operating system, right down to the last decimal place
    The identities of any third-part video cards
    Got any drivers for these cards?  What are their PRECISE version numbers?
    The horizontal & vertical dimensions of your comps and frame rate
    The media container (.mov, .avi, etc.) and codec(s) of the clips you're using
    Got audio clips?  wav, aiff, or something else?
    What kind of still images are in the project?  Bitmapped or vector?  What are their horizontal & vertical dimensions?  Are they RGB or CMYK?
    What kind of effects are you trying to use?
    Trying to use ray-tracing?  You shouldn't.
    Trying to use multiprocessing?  You shouldn't.
    This isn't an all-encompassing list, but it ain't bad.  So toss the people here a bone and cough up some information, okay?  Give us a fighting chance, and don't make us rely on crystal balls.

  • After Effects Rendering problem

    Hi, I am having a problem with After effects CS6, I know the newest version of Afer Effects is CC but I don't like CC and I have never had a problem like this before, I'm sure the fact that I don't have CC doesn't make much of a difference, I am making a Call of Duty montage, all clips being .wmv, 59.94 frames per second, and 1280x720 pixels. I had made it halfway through the montage with no problems until this came along. When I ram previewed before the problem came along it would render out the whole video with the music and effects. Then I added the next clip to edit and once I was finished with that clip the whole video was 48 seconds (still not done with the whole thing) and when I did a ram preview to see the first 3 clips together, the ram preview only rendered out to the end of the second clip at 22 seconds and kept on playing only the 22 seconds over again. I have looked up basically everything, I tried restarting my computer, I also did Edit > Purge > All memory and much more, nothing is working. I am running on a Windows 7 64 bit operating system with 8 GB of ram, my processor is a Intel Core i5-3330 @ 3.00GHz. Please try and help me out on this, thanks.

    RAM previews use your system memory and you only have so much of it before you run out. More frames, more memory usage. Higher (preview) resolution, more memory usage. And so on... Sounds like you simply previewed at reduced resolution when it seemed to work and now have switched to a higher one. Can't defeat the computer math... Switch your res to 50% or even 25% to increase preview duration...

  • After Effects rendering issues.

    I am currently trying to render a composition from After Effects, but every time I run into the same problem. Rendering starts then suddenly finishes, leaving me with a 68kb .mov file. The composition is rather large, about 5 secs. long and contains alpha. However, I have rendered similar projects without dificulties. Any ideas as to what might be the problem?

    Try to debug it. Enable the Extra per Frame Info on the render queue and see where it stops exactly. Also twirl open the extended info on the -coRender Queue panel, this might provide additional clues. it tells you exactly on which premp or layer it's chewing currently. This may reveal the baddy.

  • After Effects rendering issue

    Lately anytime I am rendering a clip in After Effects for a project and then jump into premeire to do some edits the render in AE just stops right where it is. Anybody else have this issue and is there a fix?

    Image sequences do usually support MP rendering, but any codec that must process frames in a linear fashion may not. That includes most of them. What we are calling MP rendering is really rendering multiple frames simultaneously. If one renders faster than the next one in the sequence due to a longer path through the system buss and you are using a process that is linear then the whole process breaks down very quickly and things have to process the errors, stop the process until everything gets re-set, verify that everything is in order, figure out which frame from which processor is next, start again, then check the sequence again. That's an over simplification of why rendering to a linear codec or trying to render a plug-in that uses linear processing like a particle system can break down with MP or rather more accurately RMFS rendering turned on.

  • Can MacBook Pros handle After Effects renders in HD?

    Hi all:
    I'm trying to determine if the new MacBook Pros can handle AfterEffects renders in HD (1020x1980).
    My Powerbook G4 has given out and I'm trying to decide between repair ($300) or replace ($3000). The one thing that it couldn't do was render After Effects projects if they were HD. (well, it could - but it would give an estimate of a 7 hour render for a pretty basic 10 second animation). With probably 80% of my work being in HD nowadays, if I knew the MacBook could handle that, it would seal the deal for me.
    If it matters, I'm using AE CS3 because my desktop isn't compatible with CS4. I would also prefer a 15", but am fine going with the 2.8GHz/320GB/7200. (And would do the 17" if it is capable and the 15" isn't)
    Thanks!

    Late reply, I know ...! Thanks, Jerry, I tried that - actually, we found that the issue was that the clips that worked from AE were 23.976 fps, and the clips that didn't work were 23.98. Adjusting the frame rate in AE did the trick.
    You live and learn!

  • After Effects CC - Export Still Frame

    Hi,
    I have recently upgraded to CC. I am trying to export still frames as a jpg from After Effects CC
    CS 5.5 (and previous versions) allowed me to use the shortcut ctrl+alt+s to add the current frame to the render queue as a still frame.  I would then change the format via the output module.
    The same shortcut in CC opens a dialogue box with psd as the only available output format. Composition> Save Frame As > File... also results in psd format with no other options.
    Is there a simillar simple process for exporting a still frame jpg via the render queue?
    Thanks in adavance

    scott_travers wrote:
    There does seem to be some unnecessary changes.
    However i have resolved this myself, if you click ok on the dialogue box and except the psd format, it adds it to the render quene where you can then change the format. No idea why there aren't any other options in the 'Save as File...' option, only PSD.
    This is the expected behavior when you have never rendered a comp from a newly installed version of AE. It's worked this way since at least AE 6.5 (the oldest version I have installed on a nearby computer to compare). The output module needs to have a destination for the file, so when you invoke the Save Frame As File command for the first time it brings up the Save As dialog. For the same reason, if you were to add a comp to the Render Queue directly it won't allow you to render until you set a destination.
    After the first time you create a output module with a destination, AE will remember the last-used location and use that by default without asking you. The only time you should it would ask you again is if you destroy AE's preferences or if the last-used location is no longer valid (deleted folder, disconnected drive, etc.).
    The reason the only selectable format here is PSD is because that is what the default OM for Save Frame As File uses. You can, and should, change this if you always use a different format. Go to Edit > Templates > Output Module . Create a new template with your desired settings and assign it to Frame Default.

  • Computer specs for nice 3D rendering/ after effects rendering and video rendering in general ?

    Hi there! I would like to know what the perfect specs for a laptop/workstation/computer are, so that I could do my creative work from home..my old laptop (Macbook Pro, 8Gb Ram, V 2010) is not good enough for 3D rendering, not even Video rendering or After Effects... I need to know what graphics card for eg or how much Ram or what I need to look for in a computer so that I won't get any error messages after rendering for half a day anymore...;) (--> very annoying) Money is not a first priority...i would first like to know, what the best option would be that one could have and then down size from there;)
    I would appreciate every help:) my laptop is dying...i need something new and better;)
    cheers stephs

    Regardless of workflow, you want a workstation, not a laptop. You will get much more bang for your buck.
    Also, as others have said, Windows machines tend to be better choices than Macs right now. And that's coming from two people who used to use/love Macs...
    In general, you want the fastest clock speed on your processor that you can afford. You want as many cores as you can get with that nice, high clock speed.
    Ideally, you want 4GB of RAM per core of your processor - MINIMUM 16 GB of RAM, (but get as much as you can afford).
    You want an SSD for your cache and a good-sized regular hard drive to hold footage, renders, etc.
    GPU matters for Premiere and any third-party plugins that use it (like Red Giant Universe, Element 3d, Mettle's ShapeShifter, etc.), but not for AE and not for Cinema 4D (which comes free with AE these days).
    Again, this is just some generalization. For more specific info, we'll need to know more about what you're doing.
    Also, you don't need to take our word for any of this; read what Adobe has to say on the matter: FAQ: What computer and components should I buy?

  • Why after effects renders me with bad audio?

    I rendered almost six times and the result of these renders is that audio takes me wrong, when I play it in Windows media audio don´t reproduce, and I reproduced a file alternative to this and reproduced it excellent, the worst is that when I play in VLC or Media Player the audio is ok, that's not the main problem, because for me it would reproduce any of the programs that it works, but I need to make this video with less size or weight and when I make this process finally the audio it´s completely damaged. This has never happened before. Please help me.

    I'm not quite sure what you're saying. Are you saying that when you render from After Effects the audio sounds bad but the audio file that was in your composition doesn't sound that bad when you play it in other applications?
    You aren't telling us what your original audio file is like or what your render settings are in After Effects, so we do not have a lot of information that we might need.
    Is the sound okay when you do a RAM preview in AE?
    What is the file format of the audio file?
    What settings are you using to render out of AE?
    If your original audio is an MP3 file, try transcoding it to a WAV and using that in AE. Then render an uncompressed file out of AE and use the Adobe Media Encoder to do your final delivery file. That's the proper workflow anyway. AE should not be used to make your final compressed version.

Maybe you are looking for
