I contacted nVidia Support about my issue with GTX 770.

nVidia support recommend either upgrade to AE CC or from AE CS6 v11.0 to v11.0.4 as explained here :
https://blogs.adobe.com/aftereffects/2012/05/after-effects-cs6-11-0-1-update-bug-fixes-and-added-gpu-and-3d-renderer-support.html

Then I edited the supported_card.txt file as nVidia suggested and added a line GeForce GTX 770.
I launched AE. In Edit > Preferencec > Previews, the GPU was available and cuda found all the VRAM.
This upgrade resolved the GPU/Cuda issue (without error, and it run up to 6 times faster in rendering).

You mean that there is NO solution for CS6 ?
What do users who do not want upgrade to CC ? They remain stuck with their issue although they paid the high price ? 🙁

I found something that you should know if you work for Adobe
https://developer.nvidia.com/cuda-downloads?sid=471928

I need the confirmation from Adobe that this fix resolves the problem on AE CS6 as at first sight it does not with my configuration.

Thanks

Hi,

I just installed AE CS6 on a fast computer and GC.
My animation contains special effects (flares, extrusion and particles) added to a JPG image of Orion M42 nebula used as backround. These are some stars (dots) in that picture that are flickering.
I attached an extract of the MP4 video generated in AE.

The video generated in MP4 or MPEG2 is flickering in the first quart of the sequence then it’s OK, while the video does not flicker when generated in AVI format.
The problem is that the avi is 1.2 GB in size where the MP4 is 10 MB only.

I tried to change the nbr of frame, the key frame rate and other parameters, unsuccessfully.

BUT I found a solution outside AE to avoid the flickering.

I imported the native AVI file in Magix Video Pro (you can import it in Adobe Premiere Pro too) and then export it in MP4 without problem.

PS. Magix Video Pro or Premiere Pro are interesting additional tools as they come with many text presets and animations that you can easily apply up to frame level.

It’s a pity that a software like AE cannot generate correctly a MP4 file including flat images (jpg).

I consider this as a bug to fix.
