alpha channel won't work - titles over footage

banczak wrote on 2/17/2012, 10:19 AM

Hi all,

I'm trying to put animation titles over my footage. I didn't create the titles, they were done for me, they are mov's. my animator is a professional so I know whatever he did to the clips were created correctly. He uses FCP though, so he has no idea how to help me.

I have my movie footage on one track
I put animated title clip on a track above my footage.
Then I highlighted the animated title clip
clicked on media
selected premultiplied for the alpha channel
field order is none
I click okay and nothing happens.

any suggestions would be appreciated, thanks.
I'm using vegas pro 10.

Please drag one of the FCP-created clips into Mediainfo and post the particulars of the file. Also, since it came from FCP, I assume it is .mov? Do you have Quicktime installed?

Melissa,
Are you sure the clips is carrying an alpha channel?

Click on the media, select properties and look at the Media tab.

The last number in Attributes: 1440x1080xNN should be 32(-bit). 24-bit clips don't carry an alpha channel.

HTH,
Tom

yes, I have quicktime pro. the files are 32 bit, I just talked to the guy who created them.

he sent me a version done in fcp with the titles over my footage and it's just fine. then he gave me the raw files done in 32bit to lay over my full quality hd footage.
there's a step with vegas that I'm missing.

Have you tried the other 'Alpha' options in Vegas?? There are three..

Okay, screw alpha channels, I just chroma keyed it instead. Works fine now.
thanks for the replies though.

I'm sure it's simply a problem reading a flag in the media metadata and you have to set the alpha manually.

Very simple, just right click in either the project media or the clip on the T/L, select properties, click on the media tab and set that alpha channel correctly (likely needs to be straight unmatted).

If you had a color background, then it probably didn't have an alpha. did you open it in QT to see if it listed having an alpha?
