best codec to get file size down without killing the quality?
on Oct 12, 2010 at 12:48:22 am

I need to send videos to someone overseas to chroma key. I can only send them via the internet.

What is the best codec I can use to get my file size down without killing the quality.

Thanks

The answer depends on a few variables. First off, how many minutes of footage do you have?

Okay, let's assume you have SD footage captured in a pro video codec like ProRes 422. Exported at the source settings this will run you into the 2-4GB range. If you have a fast connection and lots of free time - upload that. May require a couple of over-nighters. And they would have to have a fat pipe on the other end as well. But, there are a few too many variables to make this solution a smooth experience. In my opinion, your only other option would H264 Quicktime, encoded at a fairly decent data rate. Not ideal for keying but if the key was shot well then you may have a fighting chance. Still a dicey proposition, however.

Honestly, it would surely be quicker to post a disc with full res files. Chroma key really needs the best quality files both sent AND returned. Crunching down to something that can be sent by internet faster than postage will cost quality heavily both directions.

But you haven't told us important details like source codec and what the final delivery format is going to be.

Final delivery is going to be for the internet. Its a series of "walk on website videos" (where it looks like the person is standing on your website.)
