Ffmpegx missing codec components?

[plugues]

I've just installed ffmpegx with the sole purpose of converting h264 video to Xvid. However, I get the following error message when processing:

Cannot find codec matching selected -vo and video format 0x68637061.

Do I have to install Xvid separately? Where should it go, which folder?

0x68637061 is "apch", not "divx" or "xvid". Hex chart: http://www.ascii.cl/

I think you need Final Cut Studio: http://www.hv20.com/archive/index.php?t-8058.html

I have FCP, and the source file is in Prores, so yeah, you're right. Thanks for that.

I'm guessing I can solve this by converting the original Prores file to some format compatible with ffmpegx. What would be a good choice for this? Uncompressed 8-bit? DV? Motion Jpeg?

I don't know what choices you have but for best results you usually want to use an uncompressed or losslessly compressed YUV format.

With ffmpegX, you could try the XviD ffmpeg preset in combination with the 'Decode with QuickTime' option setting (to utilize FCP's ProRes codec).

that didn't work. i get an .avi which is not video, but still frames that last for about 3 minutes each
