I am also not talking about “increasing DOF so that the greenscreen is sharp.” As I mentioned, the borders of the subject need to be fully sharp. How that happens is with DOF that places the subject in sharp focus and by reducing motion blur.

Your opinion is your opinion, but practically speaking, there’s little to no apparent visual difference between footage shot at 1/48 and 1/125.

Using an adequate depth of field is a given for any kind of setup, greenscreen or not, but yeah, borders especially need to be sharp on greenscreen. I almost always shoot all my footage at 1/125 second and never had anyone complain about how it looked. Even someone sitting in a chair talking may decide to wave their hand(s) around, so I tend to not take any chances on greenscreen. And in fact, the only time I had issues in post was with motion blur because again, unsharp borders. If anyone wants to see how awful 1/48 second footage really looks, watch a sequence with movement in it, frame by frame. Even moderate movement is completely blurry at that speed.

As mentioned, frame rate doesn’t matter. It’s ALL about shutter speed, and having the greenscreen at a proper evenly lit level relative to your subject. I’ve done a LOT of greenscreen shooting and posting and don’t believe I have ever worked with 30fps footage.

The plate shouldn’t make any difference. A good key is a good key.
Are you sending a 10 bit video signal to the keyer?

I’ve done a LOT of greenscreen work, including post work, and even though I’ve never used a switcher, it sounds like either exposure is low or it’s really just a settings issue with the switcher. Possibly both.

Are you saying gel stayed on windows for a couple of weeks just by using Windex? Hmmmm…
I’ve never been able to get gel to stay put longer than about 24 hours using soapy water.

No, I have never seen this or even heard of it. I find it hard to believe that an actual glass surface would be in any way compromised by application of gel. If we were talking about a resin or plastic surface, maybe. There may have been residue, but it would just be sitting on the surface of the glass and would squeegee right off with some water.
