What recording formats are there and what are the differences?

Intra-frame compression compresses each frame individually, providing better editing flexibility and quicker response.

Long GOP (Group of Pictures) compression compresses across multiple frames, making it more efficient in reducing file size.

Color sampling refers to how much color information is recorded.

The more evenly color data is sampled, the better the color reproduction is, and the cleaner the result is when techniques like green screen compositing are used.

The best is RGB 4:4:4 (full-color information), followed by Y:Pb:Pr 4:2:2, and then 4:2:0.

Bit depth describes the gradation of brightness information.

8-bit images have 256 brightness levels, while 10-bit images have 1024 levels, resulting in smoother transitions from light to dark.

The bitrate is the amount of data recorded per second, usually expressed in Mbps (Megabits per second).

For the same format, a higher bitrate generally means higher image quality.
