Correct. I was disappointed to find this out as well. Supposedly it’s due to these codecs requiring a paid license to use. With windows the license cost is baked into the cost of the windows license itself, but of course that doesn’t exist with Linux. It CAN work on Linux if you purchase the studio version of Resolve, but I wasn’t ready to shell out $300 for a video editor when I’m only producing content for Youtube as a hobby and for the fun of it.
