Chromakey workflow question
 

Hi All - I've really been hunting for the right answers (for months), as well as testing quite a few things myself but I'm still a little unclear on Chromakey work and Cineform. I own AspectHD - works great for converting and using my HG10 footage. Have tested both ProspectsHD and 2K. I'm shooting a lot of green screen, talking head stuff for my job and putting that on top of DJ backgrounds, etc. I've key'ed out the green in both Ultra and AE (CS3) and rendering out to the three flavors of Cineform. Only Prospect2K (trial) would show the transparency (I think it's the only one that supports alpha channel - correct?). Question - Will it show the transparency in real time (as it's playing)? In my tests I only see the transparency (or underlying clip) when PP (CS3) is 'stopped", as soon as I hit 'play' the transparency goes away and I see my talking head in a black square (what has been keyed out). What am I missing, not doing . . should be doing differently . . .any advice is greatly appreciated!

We don't offer playback acceleration with the alpha channel on yet, waiting for more market interest in alpha channel features. However, if you use CTRL+Spacebar to playback it will do a playback preview with the alpha active.

Thanks!
 

that was a super fast answer! Thanks.

That's typical of David/Cineform. Most companies stay away from the front lines, but not David. That's why he gets my respect and my business.

Amen.
We are very fortunate to have David's technical offerings . Cineform is VERY WELL RESPECTED.
