I am making a video/estim combo for self bondage and looking for exquisite content, ideally 4k and/or 60fps.
As someone who edits a ton with the kinkier stuff:
There's generally less content, and this means you have to go back in time to find shots as well. This means that even getting 720p@25 footage can be hard at times. You can find 1080p@25 stuff as well, but the amount of footage cuts by quite a lot. Limiting to more recent releases will work, but the 4k shots are far and few in between currently.
If you end up mixing content, then usually the most common frame rate wins and becomes your sequence frame rate. You'll have to adapt the other clips to this. There's so little 60fps content out there that this will almost invariably become 30fps or lower as well. And the content I found where you could claim it's 60fps-ish are interlaced 30fps.
4k shots are nice in a 1080p sequence if you want to do any kind of transform (zoom/pan), because they retain their sharpness as you do so. 60fps is really nice if you want to slow-motion part of a clip at 50% speed in a 30fps timeline.
Next up is bitrate. Your 4k@60fps shot is worth nothing if the bitrate is so low the quality suffers. A lot of streaming sites will aggressively transcode to a low bitrate in order to handle the streaming cost, and also drop resolution to 1080p or less. Look into downloaders such as yt-dlp if you go this route, because they can grab the highest quality transcode for you.
Editing 4k@60 requires way more processing power than 1080p@30 (8 times more to be exact). This means you are likely looking at a proxy workflow, where you generate a low resolution proxy to stand in lieu for the original file as you edit. On delivery, you then disable the proxies and use the originals.
Perhaps surprisingly, the quality of the content is all over the place. Some content creators you would expect to be amateurs have far better grasp of working with a camera than some of the "pros".
Color-wise you are looking at 8-bit and 4:2:0 chroma subsampling for the vast majority of work. Reflective Desire, mentioned already, has done a few shots at 10-bit, which immediately makes their stuff much easier to work with color-wise. Color Grading is generally non-existant.
My sequences are 1920x960p@30 at the moment. I might go for 25 fps next time because there's so much footage around that rate. This gives you a workspace of 60 pixels top and bottom for a 1080p shot. This lenience helps a lot if you want to pan a bit, or stabilize a shot for someone who were trying to keep the camera steady while a nice lady rode cowgirl on top.
