I've developed the tool further along the way and the latest change was to add the support for encoding end credits using different Q and --cpu-used.

I think the next bigger step will be adding...

The hue shift issue occurs when using FGS and 8-bit input, works fine if the source is converted to 10 bits or an FGS table is not used. I didn't check if it applies to 8-bit encodes, as there's...

Yes, I have noticed the same thing myself. I've been trying to find out the reason and I think I've caught it.. if you feed 8-bit input to aomenc (and encode at 10 bits as is recommended), the result...

I've now pushed the latest version to the repo. Quite a few small tweaks there, namely the ability to tweak the saturation of the FGS analysis clip and doing tone mapping of HDR sources (using...

With aomenc, it's at least currently recommended to switch the regular AQ-mode off as it just blurs the image even more. --deltaq-mode (1 for SDR, 5 for HDR) and --enable-chroma-deltaq=1 are what I...

I think at least aomenc already has frame threading disabled by default, it only does row-based multithreading unless you change the parameters.

While developing the tool and testing AV1, I've...

The film grain table creation was reworked and based on my tests, it works as expected. Now I suggest looking up a short, representative frame range (100-200 frames will do) without scene changes for...

I added some tile parameters in the presets if anyone wants to use them. 1080p comes with --tile-columns=1 and presets meant for resolutions above that --tile-columns=1 --tile-rows=1. I didn't notice...

Probably because I didn't know about it :D

Maybe I'll implement it as an option as well, shouldn't be too hard now that things are as functions.

Most of the big stuff is done now, I just added the capability to use PySceneDetect for scene change detection.

I think the aomenc-lavish fork is not that bad, it has some psy tunings and psy related fixes compared to the original. Of course, AV1 like the other modern encoders, tend to be biased towards...

Another update, now you can create the Film Grain Synthesis grain table (semi-)automatically.

The next thing to do is to implement a better method for automatic scene change detection, ffmpeg is...

I've done some more work on this, now you can use ffmpeg for detecting the scene changes as the first phase of the script. I'll also add an option to use a different script for the detection (so you...

I recently got into looking at AV1 as a codec option as my new media player (Homatics Box R 4K Plus) supports AV1 decoding in hardware. I've experimented a little bit with the 'lavish' mod of aomenc...
