The film needs post-toning. When shooting in the early stage, which code has the most room for color matching in the later stage?

If you want to have more color space, try to choose RAW, ProRes422, ProRes444, DNxHD and other formats, and shoot with 10bit or 12bit.

The advantage of RAW format is that it can record the original data of camera sensor, so it can provide the colorist with the richest image data and original color space in the later work. ProRes422HQ coding, ProRes444 coding and DNxHD coding can usually be shot in Log mode, and the maximum tolerance can be obtained under the limited bit depth.

RAW format needs to be transcoded to a low-quality offline format for editing, color matching and shooting, and then restored to the original media. The toned format should be output as 10bit or 12bit as far as possible, and then the clip should be copied and output as one piece.
