I find compression color artifacting for webm tends to always skew purple when you are over-compressing a file. I used webm for retards, not sure which version, the app doesn't really have an about or .ini file.

So basically I capture using OBS, .mkv file type as that still produces a coherent video file if the application or computer crashes during recording. X264 encoder, CRF rate control with a CRF of 20, or 23 if I'm recording very long stretches to save space with veryfast CPU preset.

Webm for Retards can convert directly from MKV no problem, no need to remux. Editing software needs remuxing though. for the conversion settings I use Variable mode with high quality and then manually dial back either the resolution or frame rate if it comes out blasted. In less busy scenes I raise the conversion CRF to 39-42. VP9 will make conversion take longer and I've never noticed a quality increase. A lot of people say to just set the size limit to 4mb, and that sure is easier, but has always produced worse results in my experience.

Factorio can be particularly rough on video compression due to how many moving parts there are and visual effects like water ripples, belts moving, rain, cloud shadows etc. Part of why Dosh's videos get fucking blasted for the first few days on youtube. It just is what it is.
