Export codec with alpha and sequence markers?
Is there a codec I can export with that will carry over an alpha channel and Premiere Pro sequence markers to After Effects?
I can’t use dynamic link because I want a single video file I have already keyed with Ultra in Premiere Pro.

Basically what I have to do is render out a bunch of small videos as alpha files with a circular mask around them for use in a flash project by another person. Each video will be presented in a circle.
I figured that the easiest way for me to get these all lined up properly is to export the video from Premiere Pro as a single video file with an alpha channel. Then apply the circular mask to the whole video and render out each section of that video using my Premiere Pro sequence markers to tell me where each section begins and ends.
If I export without sequence markers I have to go through and find the beginning and end of each section by hand, so I was looking to try and save some time in AE.
Dynamic link doesn’t work because it imports my Premiere Pro sequence in AE with each section on its own layer unkeyed.

To answer my own question DNxHD in a mov wrapper carries over the sequence markers from Premiere Pro. Which I’m super excited about. I don’t know if that’s an attribute of the mov wrapper itself and it works with other codecs, the only one I tried is DNxHD because I needed a high quality intermediate file with alpha channel.
Yay!

Cool to know! Thanks for the info, Michael.

I wasn’t aware DNxHD includes alpha channel. Well it’s cool if it does 🙂
