| Flag | Description | Recommended Setting | | :--- | :--- | :--- | | | Quality level. 0 is lossless, 63 is worst. | 20-28 (Lower for HD content) | | -b:v | Target bitrate. | Set to 0 for CRF mode. | | -deadline | Encoding speed/quality trade-off. | good (default) or best (slowest). | | -cpu-used | Speed vs Compression efficiency. | 1 to 4 . (1 is slowest/best compression, 4 is faster). | | -row-mt 1 | Enables multi-threading row-level. | Essential for faster encoding on modern CPUs. | | -tile-columns | Improves decoding performance on players. | Use 2 for 1080p. |
If hardware VP9 decoding is broken (glitches, green screen, audio desync), force software decoding via libvpx : outlander s08 libvpx
