Av1an
All-in-one tool for streamlining av1 encoding
Easy, Fast, and Efficient
Start using AV1 encoding. All open-source encoders are supported (Aom, Rav1e, SVT-AV1).
Example with default parameters:
./av1an.py -i input
With your own parameters:
./av1an.py -i input -enc aom -v " --cpu-used=3 --end-usage=q --cq-level=30" -ff " -vf scale=1280:-1 "
-w 10 -p 2 -a "-c:a libopus -b:a 24k" -s scenes.csv -log my_log -o output_file
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 (aom or rav1e or svt_av1. Default: aom)
Example: -enc rav1e
-v --video_params Encoder settings flags (If not set, will be used default parameters.
Required for SVT-AV1s)
Can be set for both video and image mode
Must be inside ' ' or " "
-p --passes Set number of passes for encoding
(Default: Aomenc: 2, Rav1e: 1, SVT-AV1: 2)
At current moment 2nd pass Rav1e not working
-a --audio_params FFmpeg audio settings flags (Default: copy audio from source to output)
Example: -a '-c:a libopus -b:a 64k'
-w --workers Overrides automatically set number of workers.
Adjust accordingly to your system
Aomenc recommended value is YOUR_THREADS - 2 (Single thread per worker)
Rav1e and SVT-AV1 uses multiple threads,
Example: Rav1e settings " ... --tile-rows 2 --tile-cols 2 ... " -t 3
-s --scenes Path to file with scenes timestamps.
If given `0` spliting will be ignored
If file not exist, new will be generated in current folder
First run to generate stamps, all next reuse it.
Example: "-s scenes.csv"
-tr --threshold PySceneDetect threshold for scene detection
-ff --ffmpeg FFmpeg options. Example:
--ff " -r 24 -vf scale=320:240 "
-fmt --pix_format Setting custom pixel/bit format(Default: 'yuv420p')
Example for 10 bit: 'yuv420p10le'
Encoding options should be adjusted accordingly.
--resume If encode was stopped/quit resumes encode with saving all progress
Resuming automatically skips scenedetection, audio encoding/copy,
spliting, so resuming only possible after actuall encoding is started.
/.temp folder must be presented for resume.
--no_check Skip checking numbers of frames for source and encoded chunks
Needed if framerate changes.
By default any differences in frames of encoded files will be reported
-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.
* Both Video and Image encoding* (Single frame to .ivf, can be viewed by videoplayer).
* 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 encoding option with FFmpeg.
* Logging of progress of all encoders.
## Install on Windows
### 1. Use ready [Release](https://github.com/master-of-zen/Av1an/releases)
Just unpack it to desired folder and use like ` av1an.exe params`
Autobuilding .exe from current git available at [AppVeyor](https://ci.appveyor.com/project/master-of-zen/av1an).
All .exe for ffmpeg, and encoders should be in same folder
### 2. Install with dependancies
* [Python3](https://www.python.org/downloads/)
* [FFmpeg](https://ffmpeg.org/download.html)
* [AOMENC](https://aomedia.googlesource.com/aom/) For Aomenc encoder
* [Rav1e](https://github.com/xiph/rav1e) For Rav1e encoder
* [SVT-AV1](https://github.com/OpenVisualCloud/SVT-AV1) For SVT-AV1 encoder
All .exe for ffmpeg, ffprobe, and encoders should be in same folder
Install all requirements listed in `requirements` file.
If installed programs don't added to enviroment variable,
executables can be put in same folder with av1an
Run with command: `python -i ./av1an.py params..`
## Install on Linux
* [Python3](https://www.python.org/downloads/)
* [FFmpeg](https://ffmpeg.org/download.html)
* [AOMENC](https://aomedia.googlesource.com/aom/) For Aomenc encoder
* [Rav1e](https://github.com/xiph/rav1e) For Rav1e encoder
* [SVT-AV1](https://github.com/OpenVisualCloud/SVT-AV1) For SVT-AV1 encoder
Install all requirements listed in `requirements` file
Optionally add Av1an to your PATH
Run with command: `av1an.py params...`
