  exporting compressed video files with alpha to import to Adobe Premier Pro 1.5

  Posted by Jimmy D on October 22, 2005 at 10:13 pm

  I m using After FX 6.5 for motion effects and Premier Pro 1.5 for creating a clip. I would like to export my few seconds effect clips from AFX to PPro but not uncompressed. Lacking the hard drive space needed to export the files uncompressed, the only option to have the alpha channel exported along with the RGB is the quicktime format. Unfortunately QT format is not supported by PPro and I don’t want to convert the QT file to an other format as this will result to loss of quality. Any ideas on how to export files from After FX compressed with alpha to use in PPro?

  Dear Jimmy,

  Uncompressed is the only option I believe as you have to embed the video + Alpha channel into the clip, I have only had experience with Uncompressed Quicktime, you’re other option would be to render out an Targa TGA Image sequence as this will retain the Alpha channel information. The files are quite big though.

  Let me know how it goes and if you need any assistance.

  In the old days of Premiere 6.5, you could import separate matte and fill layers (RGB and alpha components as seperate video files) and I presume you can still do the same thing. (Sorry, don’t use Premiere anymore myself)

  But seriously, if your clips are “a few seconds” as you say, why can’t you use uncompressed files? If you are so short on disk space then a hard drive upgrade will make your system run more reliably, faster, and allow you to retain the quality your work deserves.

  all the clips together may take 2 min but its not a great deal after all. You are right about the extra hard drive but my concern is not just the space taken but storage as well. I want to back up every project of mine and I end up with lots of DVD discs and eventually I get confused where I have one clip or the other… But overall, I think I will go for the uncompressed files. Thanks for the support.
