There's also a tune=0 parameter that improves the visual quality (at the expense of PSNR).Ffmpeg development journey (6): Explain the use of ffmpeg commands on the Android platform If it is really grainy, feel comfortable going above that. If there isn't any noticeable grain in the original, then a level like 8 is fine. If there is some way to specify svtav1-params, then you will additionally want to use film-grain. Current encoders are a whole different level than a generation ago in speed, but AV1 is a more sophisticated/complicated codec than VP9 or HEVC, so it will generally be at least a little slower. Start with 6 to make sure you don't get disappointed in AV1's speed. I'm not sure how slow 'veryslow' is, but it might be more comparable to, like preset=4.

It is reasonably fast and puts out reasonable quality. I don't see people using very low values like 17, so you might need to play around. CRF values are not comparable across encoders and the SVTAV1 one goes higher than HEVC does. The easiest to use, perhaps, is SVTAV1, which will perform well if you have a lot of cores on your computer. I think it might make sense to give AV1 a shot. At least, that's my experience with them. Current AV1 encoders are not tuned for high bitrate video (they seem to be designed to really squish the files down for streaming). If you are trying to save disk space or be compatible with the web, then AV1 is a good choice. If you want to switch to VP9 or AV1, then a good reason would be because you want to play it back through a web browser, or because you don't want to support the software patent mafia.ĪV1 has higher compression by a good measure, and can be played in a browser. VP9 and HEVC are similar in efficiency, with HEVC taking the lead in higher-fidelity video.
