Thanks for your Time

Just turn off the background button for your layer (the stage window will reflect this) and render to a format with an alpha channel.
Hope this helps.

Turn off any BG images in the comp. when you render, for format, Choose Tiff, TGA, or PNG, and then in the options, choose save Alpha channel, and remove Black BG

No way to do a 32bit AVI with Alpha enabled? That would be the most ideal. I work with Vegas as well and for the moment I just render on black and do an overlay in Vegas. It works, but isn’t perfect.
With programs like Bluff Titler and Serious Magic Ultra supporting alpha in AVI, surely it can be included with PI.

Not currently. Frankly, using uncompressed AVI seems pointless when Quicktime with animation compression is just as good and smaller. If I could have what I want, that would be what I’d like to see in pIllusion QT for both PC and Mac with Alpha.

That’s becasue you’re using an imperfect method. Render with the Remove Black BG option, and you will have a Straight Render with an Alpha – a much better choice for compositing.
If you are using particles that are both intense and non intense, then things get comlicated. In that case, even though this is for After Effects, see the following tutorial on “Create Non-Intense Alpha,” which may or may not help depending on what transfer modes area vaialble in vegas (I don’t use it, so I don’t know).

6 of one, half a dozen of another. I only used AVI as an example because currently that is all that PI supports. If they put in Quicktime support with alpha available I would support that as well.That’s becasue you’re using an imperfect method. Render with the Remove Black BG option, and you will have a Straight Render with an Alpha – a much better choice for compositing.
But that only renders out individual frames that you then have to recombine into a sequence. Just more steps. Most of the stuff, overlay or luminance key works fine for a quick and dirty job. If I need a well done composite I bring the footage into PI and render the sequence back out from there. It would just be nice to be able to render a full sequence out to AVI or Quicktime with an alpha channel.Thanks for that tutorial on color fringing. That will come in handy.

[LynxFX] “6 of one, half a dozen of another.”
No, it’s not. That expression means they are of equal value, and that’s not the case. Quicktime files with Animation compression and an alpha channel can be signifficantly smaller (we’re talking Gigabytes here) then an uncompressed AVI.
[LynxFX] “But that only renders out individual frames that you then have to recombine into a sequence.”
You make that sound like it’s difficult or time consuming. While I don’t use begas, it’s my understanding from Elvis’ comments here thaty you can just impoirt them as a sequence and that it’s simple to do. In AE, you just select one image from the sequence and then tell it that it’s part of a sequence, and AE does the rest, in seconds.
Is that not how it works in Vegas?

Yeah, Vegas does have an Open Still Image Sequence checkbox when you select the first image of a sequence. It can’t write out image sequences with alphas, but it can import them no problem.

Does Premiere and/or Premiere Pro do it the same way, with a checkbox? If so, what is this option called? If not, how does it do it?

Oh give me a freakin break. Where’s that rolleyes icon when you need it. The end result is the same and I could give a rats ass about file size for this. You like your quickietime and that’s fine and dandy. We were both talking about getting an end result and we’ll leave it at that.You make that sound like it’s difficult or time consuming.
I actually believed it was until I saw Elvis’ comment. I didn’t notice the image sequence toggle before and it brings them in as a single movie file no less! Alpha and all. You learn something new every day. Since it works that well, even with intense particles, my quest for alpha’d AVI or…cough…MOV isn’t that important with PI. 😉Yeah, Vegas does have an Open Still Image Sequence checkbox when you select the first image of a sequence.

Thanks for the tip! I never saw that checkbox before. What I’ve done in the past is actually bringing the image sequence into flash and rendering out alpha’d swf files which Vegas also handles beautifully. Glad to see that isn’t needed. -
Aharon was just trying to be accurate, so others who read these posts either now or in the future via the archives don’t get the wrong idea — it wasn’t a jab at you.
Not knowing that all video editing software can handle image sequences the same way as movies (they both turn into multi-frame clips upon loading) is a common “problem”. It’s surprising the number of times this comes up.
