Alpha channel

[Ben Holmes]

Your alternative is to output the alpha channel as a matte. Drop into layer below the rendered comp and set comp layer (in FCP) composite mode to ‘travel matte luma’.

Just mention it if you’re struggling and up against it. FCP has some issues dealing with Alpha channels (exporting particularly), but the method you describe SHOULD work. I would check the After Effects export settings again – as I am sure you have already…

Ben – thanks for your help. I’ll give that a try, but I’m sure I’m just missing a setting somewhere, as I’ve done this before with no problems

For many reasons you’d be better off importing a 32-bit TGA sequence.

David can fcp import a sequence now properly?

I thought you had to build a quicktime out of a .tga sequence to get them to play nice.

I’ve also used motion to do that.

Yowser Chris,

It works just fine for me. I’ve always been a big fan of Targa sequences because you only have to fix the parts that need fixing and render just those frames that need to be rendered.

All the best,

There’s no need to re render an entire quicktime file either. It is an editing machine after all. Just rerender the frames or seconds neccessary and insert them into the quicktime. If you want a nice concise quicktime that’s not broken into parts, just edit the parts together and export a self contained file. There’s no further compression. I find the benefits to enormously outweigh any downsides. What a hassle to have a computer drive full of image sequences imho. With a drive full of quicktimes I just open them up in quicktime, or even in column view without opening a single app. They show up in searches and spotlight.
