  render from Ae to import in Avid Express

  Posted by Coverbee on August 23, 2006 at 8:12 pm

  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.

  Thanks very much Dave
  Much appreciated, it looks a lot better now….
  When I think back I decided to go with the straight alpha because I had used the starglow effect and it didn’t look good after rendering premutiplied.
  I’ve dropped the effect and the premultiplied render looks much better…
  I think this will work.

  btw any new tutorials coming from you in the near future ??? would be nice, thanks again

  CoverBee, if you want to keep your effect, try changing your premultiply color from black to white. You’re probably not liking your effect because AE is adding black to your edges. In premultiply mode, AE has to add SOME color to the semi-transparent edges. It defaults to black, but you can change it. Depending on what it’s going on top of, this may not fix the problem completely. But hey, that’s why they invented the straight alpha.
