Ok, so I'm exporting 40 seconds of video to Quicktime (Animation codec) full
resolution and it takes over 5 minutes. WHY?

The animation codec is a "asymmetric" codec. It spends its time compressing and organizing the data so it can play it back faster. :-)


It has been around since 1990 and will carry an alpha channel along with the video if you ask it to. While it is "uncompressed" when set to the highest quality, I can't really recommend it for exporting video, unless you are not sensitive to the YUV->RGB conversion that takes place.

I have been having excellent luck with using the uncompressed 10-bit BlackMagic codec, especially for cross-platform HD xfers from the DS to the Macintosh. You get all the bits with a minimum of fuss, and can put off all the media transformations (YUV->RGB, 10-bit->8bit, etc.) until the final stages of your workflow where they will do less harm.

P.S. One of the reasons the animation codec exists is because of this:
