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

Jimmy,
QT is supported by Premiere Pro. Do you have quicktime installed? If not, install it and you should see that you can import QT files. But, considering the nature of alpha files, I am not surprised that it takes a lot of space.Aanarav Sareen

I have quicktime player 6.3. and when I try to import qt files to premier it says “unsupported file”. Is the version old or do I have to adjust something inside premier?

Several Quicktime codecs are not supported…h263 and h264, but most have a .mpg or .mp4 file extension. Premiere works fine on all other QT files on my machines.

You should render a series of .tif or .tga or .png with compression on. They support alpha channel and the compression is lossless. I think .tif is smaller when compressed but render a few frames to see which one works for you. Note that depending on the video, these may not be much smaller than uncompressed.
Make sure you have the field order and frame rate set the same as you would for your video file.
This will create a series of files like
file_0001.tif
file_0002.tif
etc.Import them into PPro by selecting the first file in the series and check “numbered stills” box. It will look like a video file in the bin and PPro will treat it as so.
The audio cannot be saved with this, so you will have to lay it back to the audio from the original file or however you want to sweeten it.
Nice think with this is that if you crash or render a bad frame, etc, you can just start over where it crashed or re-render one frame and drop it in the series.
Hope this makes sense…once you get used to this, you will use it often.

thanks for the useful info. It’s simple to use, the only drawback is that you are dealling with lots of files and you may miss a frame or so when copying or backing up. But it’s a nice idea. I managed to save about half the size of the uncompressed video file.
