I have a movie which is in a sequence of .tiff images right now. Each of these tiff has an RGB and an alpha channel (it is a blue screen pull). I need to convert them into a single QT movie while preserving the alpha channel.

I just got QT Pro because I had heard that it could do that. But I can't find any "Convert" option and the Help file doesn't have anything under "sequence" or "tiff". Does anyone here know how to do that?

Thank you for any help.

Bo.

Number your images sequencially using zero prefixes ( 001,002,003 . . .). Open Quicktime and choose "file - open image sequence". Select the first image in the bunch and quicktime does the rest. Not sure about the alpha channel. You may have to chroma key the movie to make your composite. Use the "animation" codec for your export. In my opinion, it will key a little more cleanly than using the dv codec.

Thank jimi. My chroma key was done in another software at work.

The steps you described are just what I was looking for. THe animation codec allows you to write in millions + meaning that it includes an alpha.

Thank you.
