<h2 align="center">All-in-one tool for streamlining av1 encoding</h2>
|
|
|
|
|
|
|
|
<h2 align="center">Easy And Efficient </h2>
|
|
|
|
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'
|
|
|
|
<h2 align="center">Usage</h2>
|
|
|
|
-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)
|
|
|
|
-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
|
|
|
|
-log --logging Path to .log file(Default: no logging)
|
|
|
|
<h2 align="center">Main Features</h2>
|
|
|
|
**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..
