I was rendering bottom third and alpha channel animations from the Editor's Toolkit from Digital Juice and I had a 20 second animation with a file size over 600 megabytes (worse case--others were 200 meg, 38 meg, etc.)! Uncompressed AVI (that had transparency) was even bigger at 800 meg.

Their Juicer2 application used Quicktime "animation" codec as the default. It took 1 min 11 seconds to render.

I checked their site and learned that Quicktime (lossless) with the PNG was supposed to 1/2 the size, and still had alpha. It worked as projected, but it took 4 min 32 seconds (almost 4x longer).

In addition, I still wanted a smaller file (200+ meg was still big) so I tried the same file with Quicktime Sorenson 3 and it was only 18 meg (MUCH smaller) and was only slightly longer than the default "animation" codec setting (1 min 25 seconds). However, it did not retain the alpha channel.

I can go through all the options, but can save some time if anyone can provide a a list of common codecs that have alpha (this is a requirement--I can render the non-alpha tracks in various formats and save a lot of space). Then among those with alpha, which is the smallest size, apx. render times, etc.

Anyone have all or part of this information?

Thanks,

Ted
