An easy way to start using AV1 / VP9 / VP8 encoding. AOM, rav1e, SVT-AV1, VPX are supported.
Example with default parameters:

-bl CQ limit for boosting. CQ can't get lower than this value.
-br CQ range for boosting. Delta for which CQ can be changed
--vmaf Calculate vmaf for each encoded clip.
Saves plot after encode, showing vmaf values for all video segments.
Requires: Installed FFMPEG with libvmaf and installed libvmaf.
--vmaf_path Custom path to libvmaf models, by default used system one.
--tg_vmaf Vmaf value to target. Best works with 90-95 on 720/1080.
--vmaf_steps Number of evenly spaced probes that is used to interpolate vmaf to cq change.
Must be bigger than 3. Optimal is 4-6 probes. Default: 4
--vmaf_error Decrease initial Vmaf values for interpolation.Increasing number will result
in lower CQ and bigger final vmaf score, use to correct whole vmaf plot.
--vmaf_error Decrease initial Vmaf values for interpolation.Increasing number will result
in lower CQ and bigger final vmaf score, use to correct whole vmaf plot.
For start If target vmaf undershoot increase value by undershoot amount.
--min_cq, --max_cq Minimum and maximum CQ values used in interpolation in target Vmaf mode
Use to limit CQ values range. Default: 20, 63.

**Spliting video by scenes for parallel encoding** because AV1 encoders currently not good at multithreading, encoding is limited to single or couple of threads at the same time.
* [PySceneDetect](https://pyscenedetect.readthedocs.io/en/latest/) used for spliting video by scenes and running multiple encoders.
* Fastest way to encode AV1 without losing quality, as fast as many cores cpu have :).
* Resuming encoding without loss of encoded progress.
* Simple and clean console look.
* Automatic determination of how many workers the host can handle.
* Building encoding queue with bigger files first, minimizing waiting for last scene to encode.
* Both video and audio transcoding with FFmpeg.
* Logging of progress of all encoders.
* "Boosting" quality of dark scenes based on their brightness.
