Problem w/ Alpha channel on AVI OUtput

[Neri]

Hello !

I've got a little problem when I export AVI sequences with alpha channel and no background -> I do not have the transparency when I put the video in Vegas.
Perhaps can I use TGA or anything but I don't know how to compile them in a video sequence without TVP.

Regards,
Philippe

In Vegas right click on the clip, select properties>Media and select the proper Alpa channel.

Thanks for the reply Paul !

But I still have no result .. I tried every alpha mode in Vegas. Here are 2 screen capture:

This is very strange -- I tried everything possible and can't get the alpha channel to work either. I will try with an older version of TVP. This might be a bug. I am working in TVP 9 beta. I'll try TVP 8 Pro -- be right back.

AH! No bug. When you select the AVI codec you must select Uncompressed BGR32 -- you probably never changed that from 24, just as I had forgot about it. Keep everything else as you have it and in Vegas set to Premultiply.

Thank you so much !

I'm fighting w/ it since 1 month

I think this tip'll be really helpful for every one in here !

Have a good Afternoon

My problem has always been to remember things when I don't use them too often. You are welcome; glad to be of assistance.
