Thanx, emmrecs! I've already read that thread, but first of all it's about MEP, while I have only VPX8. Secondly, even after reading that thread I didn't understand, if MEP can make RGBA transparent? Some guys say, that it's impossible, others claim, that it works with AVI. So, maybe someone can give me a simple straight answer?

Hi

. . . . it's about MEP, while I have only VPX8 . . .

It is the same principle whichever program you are using - MEP has some features which have not yet made into VPX - however Alpha video is not one of them.

. . . . . Some guys say, that it's impossible, others claim, that it works with AVI . . . .

It is possible - I think you may have missed the second part of my answer here.

Thanx, John! But now I have another stupid question - do you know any converter, that can convert rgba mov to avi? Since I'm doing all keying in DaVinci it doesn't have RGBA avi :(

Hi

I cannot recommend any - the software I use to create effects, will export AVI with Alpha.

However there are a several converters that will do the job - two free and most popular are FFMpeg and VirtualDub.

If you Google 'convert mov rgba to avi rgba' you will find many answers and specific instructions on what to do.
