How to render in After Effects for Avid Express Pro

[Satesh Ramjattan]

the QT “animation” codec gives you the option of exporting with an alpha channel.

[Michael Hancock]

You can use the animation codec, which is lossless. Render in the correct field order so you don’t get jitters, and if you want to bring an alpha into the Avid set it to million of colors+ with a straight alpha. When you import into your Avid, select the same field order you rendered it out of and invert existing alpha.

For a faster import, visit the Avid website and download the Avid codecs. Will decrease your file format conversion time dramatically. If you use an Avid codec, use Use Existing Alpha when you import it into your Avid.

If you run into problems post back here and we’ll walk you through it.

Hi there
I’m still not sure what to do, please advice.

I made some textgraphic in Photoshop CS, sqare pixels and all.
Then I imported the layers into After Effect 6.5 as a comp.I animated it and added a few effects. nothing to hot I think just a lightsweep effect, some level adjustment, some fastblur etc.
All the composition I made in AE where square pixels.

I rendered my final comp using animation codec, millions of clors +, rgb plus straight alpha, field rendering even lowerfield first.

Just to check things I import the quicktime render into Avid Free DV. Importsettings : Maintain, square; RGB;
Invert existing alpha; Even (lowerfield first.

Somehow it looks a bit funny. wht little red dots wher is supposed to be transparency. It looks a bit like opening a QT with alpha in the quicktime player, since it is not capable of ‘showing’ an alpha channel.
I’m not sure at what stage things go wrong….
Is Avid Free DV capable of handeling an Alpha channel or not

I’ll be glad to hear from you again.
Best regards

btw. I’m working on an Apple G5. PAL format.
