Av1an
All-in-one tool for streamlining av1 encoding
Easy And Efficient
Start using AV1 encoding. All open-source encoders are supported (Aomenc, Rav1e, SVT-AV1)
Example with default parameters:
./av1an.py -i input
With your own parameters:
./av1an.py -i input -enc aomenc -e '--cpu-used=3 --end-usage=q --cq-level=30' -a '-c:a libopus -b:a 24k'
Usage
-i --file_path Input file (relative or absolute path)
-o --output_file Name/Path for output file (Default: (input file name)_av1.mkv)
-enc --encoder Encoder to use (aomenc or rav1e or svt_av1. Default: aomenc)
Example: -enc rav1e
-e --encoding_params Encoder settings flags (If not set, will be used default parameters.
Required for SVT-AV1s)
Must be inside ' ' or " "
-a --audio_params FFmpeg audio settings flags (Default: copy audio from source to output)
-t --workers Maximum number of workers (overrides automatically set number of workers.
Aomenc recommended value is YOUR_THREADS - 2 (Single thread per worker)
Rav1e and SVT-AV1 uses multiple threads,
Example: '--tile-rows 2 --tile-cols 2' load 2.5 - 3.5 threads
4 rav1e workers is optimal for 6/12 cpu
-fps --force_fps Forces fps of video. Needed when you need to change fps of video,
to prevent encoders from changing video length.
Usefully for SVT-AV1 encoder. No need to set up fps num/denum.
Example:
.. -e '-fps-num 30000 -fps-denom 1001 ..' (SVT-AV1 29.97)
.. -fps 30 -e ' -fps 30 ..' (Force FPS)
-tr --threshold PySceneDetect threshold (Optimal values in range 15 - 50.
Bigger value = less sensitive )
-p --pass Set number of passes for encoding (Default: Aomenc: 2, Rav1e: 1)
At current moment 2nd pass Rav1e and SVT-AV1 not working
-vf --video_filter FFmpeg video filter options. Example: ... -vf 'scale=320:240' ...
-log --logging Path to .log file(Default: no logging)
Main Features
**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.
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 encoding option with FFmpeg
And many more to go..
