Is there a better quality setting? - Jun 5 at 3:02PM

When exporting a video clip, the result is always horribly pixilated.  It appears that a LOT of video compression is used by default.  The resulting image is pretty poor.

I'd like to be able to export a video clip with the object motions drawn on.  But the result is always disappointing.

Is there a better way?

Sorry, there's no way to change the quality of the exported videos. You might try exporting as a JPEG image series and then using a different program to combine these into a video.

Doug,

Thanks.  I guess if I really had to the JPEG export could work.  The workflow is a little awkward.  

My experience trying to edit technical video suggests that lots of artifacts can be created such as dropped frames, duplicated frames, and lossy compression.  Even just shortening a clip in Quicktime can result in dropped frames.

Might improving video export quality be something to consider for a future release?  Perhaps that's a good project to farm out to the developer community.
