1. Re: After Effects crashes when rendering to H264
Mylenium Nov 28, 2012 5:17 AM (in response to DJravingMonkey)We need exact system specs down to the audio hardware, exact render settings, comp settings and so on. We do not even know what version of AE you are referring to at this point. And yes, of course this will have to include info about installed CoDecs on the system or possibly audio hardware.

2. Re: After Effects crashes when rendering to H264
DJravingMonkey Nov 28, 2012 12:32 PM (in response to Mylenium)I am using a HP Elitebook 8540w with Quadro FX 1800m and 8 GB Ram. And After Effects CS6 like written in the Tag line. It doesn't seem to be the System because, it worked prefectly last week.
A new fact I figured out: when I set multiplexing to none in the render module the error does not occure... (annoying workarround)
I reinstalled the whole Creative Suite Also I deinstalled all "exotic" codecs... (only ffdshow and x264...)
Nothing changed...

Dave LaRonde Nov 28, 2012 12:55 PM (in response to DJravingMonkey)Don't use AE to do the rendering. You can use Adobe Media Encoder to open the comp, and then make the files for DVD authoring. The Authoring software normally does any muxing necessary.

DJravingMonkey Nov 28, 2012 9:45 PM (in response to BenjaminMarkus)Well I know that, but I love rendering directly out of After Effects for fast previews... and it worked until this week... using media encoder is not a very satisfiying workarround...

6. Re: After Effects crashes when rendering to H264
BenjaminMarkus Nov 28, 2012 11:56 PM (in response to DJravingMonkey)In every version of AE that has been capable of exporting h.264 the quality has been significantly lower than exporting with an app that gives you the option of multi-pass rendering. This has always been true for MPEG codecs that use inter frame (temporal) compression. You just can't get the same quality without multi pass compression. This goes back to the first use of MPEG streams.
AE CS6 may have H.264 encoding broken internally, but any pro has never used AE to render highly compressed delivery codecs because AE was never designed to be the right tool for the job.

8. Re: After Effects crashes when rendering to H264
BenjaminMarkus Nov 29, 2012 12:01 AM (in response to BenjaminMarkus)Even for fast previews you should use AME. You have to save your After Effects project first, but then you can simply drag and drop your comp directly into Adobe Media Encoder. All you have to do is remember that the presets in Adobe Media Encoder aren't automatically set up to export your After Effects comp based on the work area you set up in After Effects, so after you select your preset, click it to make custom changes and make sure the Source Range is set to work area. Otherwise, you'll most likely end up exporting a bunch of black frames if your work area doesn't exactly match the length of your comp:

9. Re: After Effects crashes when rendering to H264
Mylenium Nov 29, 2012 12:37 AM (in response to DJravingMonkey)Multiplexing? Why? No need for it if you just use local desktop playback. Unless there are audio sync issues that would mandate muxing to keep the pace, it should play just fine without it. On that note it is probably a datarate issue that is causing this behavior - when you mux, you may exceed some data rate limit. Not saying it should happen and no doubt there is a bug somewhere, but on some level that may explain the issue. also check your permissions and status on your temp folders and the output folders. Perhaps AE just can't properly write or delete some temp file due to no write permissions...

10. Re: After Effects crashes when rendering to H264
DJravingMonkey Nov 29, 2012 12:58 AM (in response to BenjaminMarkus)It's not just simply drag and drop, because I have to reinsert the project for every comp i want to render ones again... or is there an easier way? Rendering out a huge amount of short clips with the same settings inside of after effects is much more time saving...
And I have to get muxxed files for customer previews...

11. Re: After Effects crashes when rendering to H264
BenjaminMarkus Nov 29, 2012 2:27 AM (in response to DJravingMonkey)You can drag and drop the project file itself, but it takes time because Dynamic Link has to identify all the comps in your project and you can only select one at a time to load. Instead, simply shift click all the comps you want to render in the After Effects Project Panel and drag and drop them into AME all at once. Then you can add as many presets or custom presets to each comp as you want. It's true you have to do that for every comp, but you have to do that in After Effects as well.
Also, to save yourself time setting the Source Range to Work Area for each comp in AME you can just right click the work area bar in After Effects and select Trim Comp to Work Area before dragging your comps over.

12. Re: After Effects crashes when rendering to H264
Patrick_Farrington Dec 4, 2012 1:27 PM (in response to BenjaminMarkus)I'm having the same problem - H.264 export crashes around the 1:03 mark every time. DNxHD is fine.
Dragging comps to Adobe Media Encoder and trying to render from there doesn't work either.
My CS6 install [last week] is on a brand new Dell Precision T7600 dual eight core machine with Windows 7.
It's ridiculous to say that we shouldn't render H.264 out of After Effects. Sometimes I render 50+ TV ads at at time from composition templates for delivery to a multitude of media outlets - each with slightly different specs.
Even if AME was a workaround, dragging all these comps over would be a crippling waste of time.
This is an Adobe problem and we've all wasted too much time troubleshooting and talking about it. PLEASE FIX.
Thank you.

SimeoneSergio Feb 13, 2013 7:24 AM (in response to BenjaminMarkus)Dear BenMarkus,
I had the need to take your advice into account as i ran into almost the same problem: AE was rendering correctly H264 until let's say last sunday... It then started to render files WITHOUT the video channel and i still have to understand why. Meanwhile i'm using AME but hey... If it worked before (and never crashed) then i don't understand why it shouldn't be working.
On a sidenote: can't you guys add a menu voice "Send to Adobe Media Encoder" directly in AE? Would save a lot of troubles!
Thanks for the help and the good work you guys at Adobe put, cheers.

rickg1949 Feb 16, 2013 8:34 AM (in response to Patrick_Farrington)Patrick,
Feel your pain! Only mine (T7600) renders fine in QT H.264 using After Effects, but "BAAAaaahhh's" when I use Media Encoder via Premiere. And only in that preset of QT, 1920x1080i, H.264. But AE renders like a champ.
Thoughts? Did you get resolution?

16. Re: After Effects crashes when rendering to H264
Todd_Kopriva Feb 16, 2013 9:14 AM (in response to rickg1949)Anyone who is having problems with exporting H.264 in a QuickTime container should read this:
QuickTime will often fail on computers with a large number of processors (CPUs), including computers with a large number of virtual processors created through hyperthreading. This is especially a problem with Apple’s H.264 exporter component within QuickTime. To get around this problem, disable hyperthreading or reduce the number of processor cores available to QuickTime. This document describes how to do this.

17. Re: After Effects crashes when rendering to H264
s_mayoral Oct 25, 2013 2:18 PM (in response to Todd_Kopriva)I tried to use AME to export to h226 but stopped because an export in AE took 20 minutes, and AME took 20 hours. Suddenly the h264 export stopped working today, yielding consistent crashes in both Mac and PC, despite there being no change in the file from the last time I exported.

18. Re: After Effects crashes when rendering to H264
Sebasvideo Oct 25, 2013 2:33 PM (in response to DJravingMonkey)If it's for fast previews, wouldn't it be faster to render to an MPEG2 based codec? If not it's easier to render to lossless and then compress to h.264 in AME.
