Encoding from Kdenlive

We need a few different encoding profiles. The main one is for actually producing episodes, for this we use VP9. It’s slow, but makes very small files. These must be small as we’ll be archiving them forever, and they must be high enough quality to not take a big hit when youtube transcodes them.

Profile Name: LP
Extension: webm
Parameters: glsl.=1 row-mt=1 cpu-used=1 crf=23 vb=0 ab=256k threads=8

Lossless encoding is great for in-project usage to make layers easier to manipulate.

Profile name: Transparent
Extension: mkv
Parameters: glsl.=1 properties=lossless/FFV1 
pix_fmt=bgra

Audio-only encoding is another part of the prcess which means no quality is lost when exporting bits and pieces, like edited sound to be mixed together outside of kdenlive.

Profile name: Transparent
Extension: mkv
Parameters: glsl.=1 properties=lossless/FFV1 
pix_fmt=bgra
