Tony_Lewis: The thing that gets me is that they have alpha already. I know they were probably going to add AVPro recording tools. If we can record in ProRes 4444, it would mean they can take the alpha view and pump it directly into a video format that supports alpha, and it would be super high quality, able to be used in a video editor, without the need for keying.

DarkSwordsman: The other thing they would have to add would be a way to exclude some Post Processing effects inside the camera itself. I honestly agree that they should definitely add the ability to record with alpha a lot easier. As it stands it's very difficult to record with transparency in OBS

Tony_Lewis: absolutely seconded. I have a pretty capable setup (7700K, 64GB RAM, 1080ti) and recording transparent footage nearly cripples my system at 1080p60, not to mention how ridiculously massive the recordings are. Alpha recording has been touted as a solution. Devs have historically refused to consider this because alpha recording is possible.

"Let them eat cake"

One of the HUGE benefits of custom color backdrops is that you get to easily select a color with good contrast. If your avatar has green on it, the green screen kind of blows for lossy recording, which is what most of us would like to use.

Teeh: the other issue with using chroma key is the chroma key artifacts, or if we have a bottle that has a tad bit of transparency. Won't look that nice in the video editor which is why I'm in favor of in game recording

Euan: tryed, this then has the problem with black parts of the model :/ (as you are then keying the black out)

minikane: you don't key anything, the application feeds the actual alpha value and obs picks it up (assuming you're using obs or an application that can accept alpha)

Euan: capering it as a game-window? (far as i see it has a black screen in game capture mode- OBS)

minikane: See the gif I linked, in OBS you need to enable something so it uses the transparency

Euan: gnfrdxcjgkvdhghjghdcfhfkdjfgf it works! why do they hv greenscreen with this? :P

minikane: For non live recording and applications that don't allow capturing alpha, although OBS can take in alpha from applications you cannot record output with alpha. (I've spent quite a while looking for something that can record alpha with no success)
