Possible to manually edit arguments?
#3
Sorry, I wasn't clear -- I'm using VP9 and AV1, specifically.

Example of VP9 (using vpxenc, as I believe Hybrid does) and CQ 2-pass: https://www.webmproject.org/docs/encoder-parameters/

relevant section: 
CQ mode is available for one-pass encodes, but is generally intended for two-pass. For one-pass, CQ applies the user cq-value, but can't adapt to a higher value if the clip is difficult.

In the two-pass variant of CQ mode there is a further refinement. If the first pass analysis suggests that a clip is too difficult to be encoded at the user-selected --cq-level, then rather than code part of the clip at this level and the rest at a much lower quality, it tries to pick a sustainable "auto-cq" level. Under no circumstances will this "auto-cq" value drop below the user-selected value.

likewise, for VP1 (libaom): https://www.reddit.com/r/AV1/comments/k7...9_be_more/ 
--passes=2
– The interesting thing about libvpx-vp9 and libaom-av1 is that 2-pass mode is actually quite fast, unlike 2-pass x264 and x265. It also enables a bunch of nice options for higher quality so use it! Only use 1-pass mode if you need to stream in real time.


That being said, I do see the option to add commandline arguments for x265/x265, but the misc tabs for VP9/AV1 don't seem to have it.
