Two questions.

Hello everyone.

I’m new to this forum, and well pretty new to the whole After Effects and CG scene for that matter, but I try to help myself throughout bumps in the road, but I’ve been stuck now for quite a while.

Before I start my rant I’d like to share with you what I’m running:

I have a Intel Core 2 Quad Q6600 2.40GHz, 4 GB DDR2, nVidia GeForce 8800 GTS 512, Windows XP Professional with SP3 and Adobe After Effects CS4.

First of all there’s rendering and not getting sound, even though I do check the “Audio Output” check box in the Output Module Settings window. At first I just thought I had forgotten to tick in that box, but after the second render (12 hours each) I went searching for this problem on Google but didn’t find anything useful, only people forgetting to render the video with audio.

Now for the second thing. I was wondering if 12 hours would be normal for a video @ 720*480 in QuickTime H.264 at full quality. So I went and looked for something that might improve my PC’s performance. I realized that After Effects CS4 comes with something called OpenGL (yes it’s familiar, but I have no clue what it does) and by the looks of it, it should be something neat. Now when I try to enable the OpenGL thingie in Preferences>Preview it just says: “No compatible OpenGL video card found”, even though the Adobe support site says that my GPU should support OpenGL applications (and so does nVidia). I updated my GPU to a version 0.1 above the minimum requirements according to Adobe’s support site, but it still gives me the same reason, that my video card is not compatible with OpenGL.

Has anyone had this problem, and if so, what on earth did you do to make it better? :o

Best regards,
nossinyer

P.S. Excuse me if my english isn’t very good, after all I am from Iceland

Check your audio and multiplexing options in the H.264 dialog as well as the profile level. Some profiles do not support unmultiplexed audio. Also consider using the straight H.264 export. It’s much more efficient than QT and avoids a number of other problems. You can always embed the file into a QT by using Quicktime Pro or tools like SUPER© to transcode.

The rest is unclear. Without knowing what exactly you do with the footage, it’s hard to tell. you could just use a ton of effects that make this slow, so the output format would not matter at all. Generally, though, H.264 encoding is slow. That’s why some company sell accelerator cards and USB-Sticks for it.
