  • Vegas 6, transparent background using PNG and transistion, possible?

    Posted by Steve Battershell on January 25, 2008 at 2:54 am

    I’m editing a peice and it calls for some product shots to be onscreen. I put these in as 32bit PNG files to maintain a transparent background around the product shots. I’d like to use a transistion to fly these in and out of screen. As soon as the transistion starts, a black box shows up around the product where the transparency was. Is there anyway to fix this?

    I just tried this and everything worked as I expected it to work. I didn’t get any black in the transparent areas. I tried a bunch of different transitions too.

    Steve, I got the same results as Edward… unless I didn’t have any media on the track(s) below the png track. Then I do get the black square.

    As an experiment, try inserting white generated media in the track below your png and see if the black box goes away – it does for me.

    I do not know of a way to maintain the transparency using a transition. However, a possible workaround is to use track motion to fly in your png. Then, transparency is maintained.

    Thanks guys you’ve given me some ideas, I’ll try these. Yes I do have media below the PNG layer.

    I had a png with a transparent background on track 1 and another full screen png on track 2. Track 2 was never blocked (no extra black anywhere) except where it should be no matter what transition I used. I didn’t try them all but I tried several.

    Hi,

    some time ago I had similar problem with transitions that came with wax. No problem however with the builtin transitions.
