I'm new to the issue as well. Apparently this feature is used a lot in  
movie editing or special effects. The mov was generated wtih 3ds max  
and the artist tends to import such movs into After Effect (some movie  
package) to process it further. Looks like this is also mentioned  
briefly on the huffyuv page.
