Hi all,

I did what most of the tutorials are showing... and it looks good on the timeline. When I go to render and then it prompts me for the codec... I choose animation and millions of colors. In the little preview window I see a thick green border around the person... but this didn't show while I was editing on the timeline. Any suggestions?

Thanks
Nelson

Render it out and see what it looks like, If you still see the green fringe around your actor, you're going to have to play with your chroma key settings, can't give you specifics since every shot is unique. You can add a spill surpression filter or a light spill composite mode... that should help.

If you are rendering with alpha channel, it is normal for the edges to look jagged and thick immediately after render. what you are seeing is the RGB channels without the alpha channel being applied. Once you apply the alpha channel, it will smooth and soften the edges back to how they were in CompositeLab.

the quickest way to adjust the alpha channel is using Quicktime Pro, if you have it, but you can use whatever program you were going to work with the alpha rendered footage in to do it as well, most likely.

Hi again, I just realized my problem is worse... I have the cast around the person cleaner now... Then I converted it to flv using flash encoder and I made sure "encode alpha channel" is on. Once that's done, I bring it in to DHTML popup pro and it shows the black box. It looks like it's not exporting from CompositeLab with the alpha channel.

Can anyone help?

Thanks

Its more likely just the method in which the alpha is being stored and/or applied. Do you have anywhere you can upload a clip of the footage to, so we could look at it? Does Flash provide you options for how to handle or multiply the alpha?

You can ensure that the alpha is being created and saved correctly by following these instructions. But it sounds like you have that bit under control, and its just the handling of the alpha afterward that is giving you grief.

Thanks so much for getting back to me... I can upload the clip. Do you want the flash file or the mov file before I convert?

I'm uploading the files now... I'll upload the original, the file output from compositeLab and the FLV from flash video encoder... just in case.

I'll update here when it's ready! Thanks for the great service.

Good golly, 1.4 GB? 1 second or so of video would have been plenty to look at, but whatever. When this finishes downloading next week I'll get back to you.

Right, so the marecheia11.mov clip, which is the one you rendered out of CompositeLab, is using a color depth of Millions, not Millions+, according to Quicktime. Since the + in millions+ is the alpha channel, it seems apparent that you aren't rendering with an alpha to begin with, which would explain the problems you have been having. I checked both in Quicktime X and Quicktime Pro 7, and both versions say the file is in millions, rather than millions+. So first, I recommend you check the Compression Settings window in CompositeLab to make sure you are rendering to millions+.

Looking back, I notice in your original post you mention selecting millions, and I probably should have caught that. The article I linked to a few posts up does explain this though, so if you can't remember exactly which settings to use next time, you can always visit the knowledgebase to double-check.

On a side note, your original clip is a bit noisy, and could really benefit from having some more light when filming. If you intend to continue shooting greenscreen with this setup, I'd look into getting a bit more light in there.

You d'man!! That worked very well! I'm usually very careful with instructions, but I missed the +... sorry.

More light would be good, but this was sent to me... so no choice there. I'll keep it mind when we do the filming.

Thank you... great product!
