which codec? 10bit 422 ? You can export a Travel Matte as a seperate file or use the Animation Codec which is a lossless Codec and handles Alpha channels just fine.

I need to render out a 1920 x 1080 uncompressed 10 bit Quicktime from After Effects with an Alpha channel…Does the BlackMagic codec do this? Is the animation codec 10 bit?
My post house requested this to lay it to HDCam tape for a textless tape to tape color correction. And the title design graphics will be added later.

Animation handles all bit depths and its full rgb and at millions plus you got your alpha. And i believe Blackmagic just uses Apples 10 bit codec, because you can load AJA codecs and still decode BM files. You can’t get the alpha on hdcamsr as far as i can tell, although there is a system setting for an alpha color on the hdcamsr but i’ve found no info on this from talking to many engineers here in hollywood. If any one knows please I would love to be wrong on this one..!! so id expect the alpha would evaporate when going to tape for color correction. you can easily make a travel matte in AE by “Set Channels” R->Alpha, G->Alpha, B->Alpha .. you basically set all rgb to alpha. thats it..
