chrissx Media Video Encoding Guidelines v0.2α

Spreading the word is encouraged.

Over the last decade of video production, mostly on YouTube (chrissx Media et al), I have acquired a bit of knowledge about video encoding. The following document lays out a few guidelines for every step of the production process.

Unless you unironically use kdenlive (personal experiences make that hard to belive) or you have toroughly benchmarked your NLE's encoder, there is one simple truth: Never Master with your NLE's builtin encoder. Instead, edit in a modern NLE (Premiere, Resolve, etc.), "export" a huge Mezzanine file in a lightly compressed format and Master with FFmpeg. The following sections lay out guidelines for this workflow.

Big audio interfaces (Focusrite Scarlett 18i8, Clarett (USB/+) 4Pre, 8Pre, ...) on Linux (pulseaudio)

When trying to use a "big" audio interface (i.e. one with many in- and outputs) on Linux, you might be experiencing problems like only some of your in- and outputs working, none working at all, etc. This is because, while PulseAudio works very well with commodity hardware, it just doesn't know your way too expensive interface. However, in a few minutes you can tell it how to deal with it.
