This might be a nvfbc bug. 2) Videos are in variable framerate format. Use MPV to play such videos, otherwise you might experience stuttering in the video if you are using a buggy video player. You can try saving the video into a .mkv file instead as some software may have better support for .mkv files (such as kdenlive). You can use the "-fm cfr" option to to use constant framerate mode. 3) HDR capture is supported (on wayland), but all GPU drivers have bugs that ignore HDR metadata so the HDR metadata will be missing in the video file.
