alternate compression options..?
on Oct 30, 2005 at 2:07:33 pm

Hi guys,

I am planning to upload some stock footage for sale online as single downloadable clips, the most preferred compression codec for cg stock footage, is quicktime png, but I find that some clips dont seem to compress down to acceptable file size limits with this codec, I get file sizes in the range of 120MB (even after compression), could anyone suggest some alternate codec which will compress it down to atleast 80 MB range?

The clips I am compressing are PALNTSC (720x576/720x486),25/30 fps, duration around 10 seconds.

please advice.

thanks.

I prefer Motion JPEG B for stock video, especially if it is interlaced. PNG is RGB 4:4:4 lossless, so it 's great for progressive graphics, but lousy compression for interlaced with video source.

Hi Ben,

Thanks for your reply, but most of it is cg and not interlaced video...

Ah, CG normally does quite well with PNG.

Are you in "Best" mode?

My suggestion is Apple Pixlet which comes out of Pixar where CG is all they wrote.
