H264 Exports from Motion 3 Only Render Half the Image
on Dec 3, 2009 at 4:58:00 pm

Hey,

It doesn't matter what i do, if I use the H264 codec when doing a simple Export from Motion 3, it only ever renders half the image. The animation and the music are there, but the bottom half of the image is just black.

The same happens if I use compressor to encode to H264 as well.

I originally thought that it was problem with my MAC, but I've since tried it on another Mac Pro and the same thing happened.

Any ideas why this happens, is it a bug?

My files tend to be created at 25fps and vary in size (resolution 720x576, 640x360 etc...)

The work around I have to do is to Export using teh Animation Codec, then re-compress to H264 using QuickTime pro. This is not ideal as it means the file is double squashed.

If you need more info, let me know.

I've had the same issue, probably memory or graphics card related. Exporting as Animation or ProRes 4444 first is essentially lossless and not double-compressing

Ok, that's good to know. Still slightly annoying though.
Glad I'm not the only one.

Thanks for your response.

Yes, quite annoying - I have the same issue on my Mac Pro, but not on my laptop.

I had this happen once, and realized I had in/out points set on my time line so it was only rendering that part. Anyway, something to check. Good luck.

Mark is correct saying that you should use 4444 codec. Please see this interesting White paper from Apple about the 4444 Apple Pro Res codec.
