Just used : Lagarith 1.3.23 : no ALPHA channel retained. Yes I selected RGBA. Yes I checked the Preumltiplied too.

Tested against a SONY Trans Text BG. Same story.

And just created a MOV Transparent BG render. So that's working.

Anybody else NOT getting an ALPHA channel render?

Grazie

Grazie, how long is it since you successfully did that with a previous Lagarith version (and which version?)? And is your Vegas version the same now?

Q1 - Hah! Has this NOT been possible then? I know I do it from Pi. Have others done this? I'm almost cartons I've done this for logo-bugs. I'm doing some lower thirds and a corpo style setter at the moment, and I went into auto Pilot to use lagarith.

Q2 - Most recent just downloaded, and the older one, both return zilch alpha trainies.

Grazie

No idea if it's possible. I rarely do anything with alpha channels. The thought of them scares me. Seeing as I seem to have become the guy in touch with the developer, I was just trying to pin down if the problem is with Lagarith in general, as opposed to the latest updates, or whether a change in your Vegas version might be responsible.

WBA ?? I'm trying to get that acronim, white balance alpha :))

RBGA=checked
Use multi threading=checked
Prevent upsampling when decoding=checked
then.. OK
Save Alpha=checked
Remove black from background=checked
Then in Vegas, right click, properties, media tab, Alpha, unmatted....

@LightAds - Where is: "Remove black from background=checked"

Where IS that?!

And the WBA - no idea what I was thinking about…

Grazie

After pressing the red record button you get a "save as" box
Then you get "AVI Options" box. In this box select "Lagarith lossless Codec" then press "configure". By the way it's in this box you'll see the version of Lagarith. Select the options above. press OK.
THEN you'll get a box "Output Options". In this box check "Save Alpha". Then another option appears "Remove black from background".

Hope we're on the same page

LA, thanks for that. I'm now gonna look see. It's just 5:00am here in London and I've got 5 hours editing time prior to seeing client, so I need to shake a leg anyway.

Cuppa tea and I'm off to see where I can fit your advice into my Lagarith workflow.

Eh? Now I really don't understand?

@Grazie: I think LightAds is talking about creating the render from PI.

I can confirm that I also cannot get a transparent background using Lagarith when I render from a generated text media clip, text against a transparent background, using "Render As..." from Vegas Pro 10b.

@Willem, yes. That's it.....

@LightAds, only silence… better I say nothing…

That's 2 hours I can't get back, soon… OK I'll stop banging my head against the wall.

Grazie

Hah!!!

Il knew I got a result, but, via Pi. Our Search facility here is a real beauty.

Thinking sideways, here's what I did:

Sorry Grazie, I was on the wrong page. I was wondering why you of all people were asking a newbie question. You of course mastered this years ago.

Hey Guy! No worries… Don't forget, I can ALSO forget. I can still be surprised. Oldbies or Newbies.
