Green Screener on the App Store. Alpha transparency in Chrome video. Exporting for HTML 5 video (.webm & .ogg) I remember that vp8/webm, ogg/vorbis, and ogg/threora are formats which are open source. this may or may not be the issue. if there is an open source license attached to any/all of the formats, then you have to check the license first. then it's quite possible you will have to stick with miro for vp8/webm and ogg. apparently, directshow has filters for theora. who knows, maybe vp8/webm too. it is under the BSD 3-line license. the bsd license usually allows for commercial development, but you will have to look at the license to determine that, and I don't see it yet. in rthe colophon it said the theora bsd-like license doesn't restrict a 3rd party from implementing theora software (but it must support playback, even in the future according to wikipedia). vp8 is under the creative commons 3.0 license. that license is described here: I got the following from "google webm": this link contains encoder code, specifications, etc. this link is the vp8 draft spec RFP (request for porposal)
How To Create Transparent Videos For The Web – WVU #73. CreativeCOW. Understanding Straight vs. Premultiplied. Should be straight alpha, but it doesn't look l... Thanks for the suggestion - it basically worked.
PPro CS3 doesn't appear to have an effect called "Alpha Key", so I used "Track Matte Key", specifying the track where I put the alpha clip and selecting Luma Key for the setting (setting it to Alpha Key didn't do anything, and it was clear that the "alpha" AVI was not an alpha channel per se, but just a regular video clip with a B&W representation of the transparency).
I also don't see any effect called "Minimax". Anyway, I followed your suggestion as best I could with the tools I have - you must be using a newer version of PPro. I can indeed see about a pixel or so that would be better if it was more transparent - I suspect your Minimax suggestion would have taken care of that. But this is definitely usable. I have no idea why I can't get it to work with an embedded alpha channel, though - surely hundreds or thousands of people use these two programs to handle RGB+Alpha video files.

Screen contamination areas: Do holes remain in the foreground? Shadows: Are they keying as desired (usually all or nothing)? Alternatively, you may discover something fundamentally wrong with your matte: Ill-defined foreground/background separation or semi-transparency throughout the foreground or background Crunchy, chewy, or sizzling edges (feel free to invent your own such terms) Other noise in the matte Edge fringing or an overly choked matte Errors in the spill suppression Keylight anticipates these issues, offering specific tools and techniques to address them.
