Common mistakes
- Typing 2 into Kdenlive's keyframe field. It counts frames, not seconds: at 30 fps that is 60.
- Entering 20 in a Kbps field. Kdenlive takes kilobits: 20 Mbps is 20000.
- Expecting HDR from Kdenlive. It exports SDR only; HDR footage is tone-mapped to Rec. 709.
- Leaving phone footage at a variable frame rate. Export at a constant 30 fps, or audio drifts and motion stutters after Bilibili re-encodes it.
- Render is in the File menu in current versions; older tutorials say Project > Render.
- Built-in presets cannot be edited: save a copy first.
For comparison, YouTube publishes 8 Mbps for 1080p at 30 fps. Example length used for sizes: 10:00.
