How to remove video from the game without compression?

Question

Video

Hello, I need to shoot a video from the game, which will be processed in a video editor and used in the video. Because the standard programs that I used are not suitable - they usually squeeze very hard and there are not enough frames.
What program do you recommend to shoot video from the game in high quality, without a heavy load on the computer (so that there are no subsidences) and also, preferably without compression or using lossless compression.
You can pay for a reasonable price.

Answer 1

try ffmpeg. In it, you can capture the screen and write with the codec you need and set as many frames as you need (the machine and the screw would pull)

You can also upload CaptureScreenshot to FixedUpdate, and then glue a ton of screenshots into a video .
