I tested different codecs for recording video in OBS 28.1.1.
| Codec name | Parameters | CPU Used | File size | Remarks |
|---|---|---|---|---|
| Cineform film 2 | cfhd -quality 3 | 23% | 625k | Good quality |
| ProRes 422 HQ | prores_ks profile=3 | 58 % | 176k | Very few frames actually encoded, practically slideshow, unuseable. |
| ProRes (alternate) | prores_aw | 35% | 334k | Single profile codec. Video is smooth but blocky. Unusable |
| DNxHR LB | dhxhd profile=1 | 15% | 160k | Very bad quality, lot of compression artefacts |
| DNxHR SQ | dhxhd profile=2 | 15% | 524k | Some compression artefacts. |
| DNxHR HQ | dhxhd profile=3 | 15% | 797k | Noticeable improvement over DNxHR SQ version, some compression artefacts remains. |
