Big problems to export video with alpha-channel
on May 31, 2012 at 12:45:54 pm

Hi,
I need a video with Alpha-channel for an Keynote presentation.
I have created one in After Effects but now I have some problems to export it.
I use quicktime with animation or png. But on both the Alpha is really crappy.
by animation i have some white stripes in it and with png the corner have an white area, I think here is png not qualified to use grayscale alpha.

Now could anybody say me how I can output video with an perfect alpha?

Best regards

There is nothing wrong with your movie... it just sometimes displays like that in quicktime.

The higher they fly... the much.

The videos in Keynote will everytime played with quicktime or will it help if I use another container like avi?
