>-lag-in-frames 25
As far as I can tell, the maximum should be 48 now.
Other than that there's a few options I don't understand the point of:
>-row-mt 1
With -tile-columns 0, doesn't that result in only one frame, and therefore make multithreading useless?
>-deadline best
Seems to be a libvpx-vp9 flag and it's noted in the documentation there that "best" may give worse results than "good".
>-frame-parallel 0
Does this help improve the filesize?
>-aq-mode 3
The places I've checked recommend not using -aq-mode 2 or 3.
Another interesting flag for low bitrate AV1 encoding seems to be
-aom-params deltaq-mode=1
From
https://forum.doom9.org/showthread.php?t=183906 :
>deltaq-mode=1 is spatio-temporal adaptive quantization based on objective metrics, working in tandem with temporal RDO (tpl-model) to get nice coding gains by deciding costs between inter and intra coding modes alongside temporal optimizations. Works well at low-mid bitrates, but at higher fidelity levels and especially grainy stuff, it can be a detriment to fidelity.
>video overran the target so much that I had to redo the audio
So you just reencoded the audio and muxed it with the old video track. Understandable I guess. These things take forever to encode.
