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=-1:720 " -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. 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 --keep Not deleting temprally folders after encode finished -log --logging Path to .log file(Default: no logging) --boost Enable experimental CQ boosting for dark scenes. Refer to 1.7 release -bl CQ limit for boosting. -br CQ range for boosting.

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 and encoders should be in same folder Install all requirements listed in `requirements.txt` file with `pip install -r requirements.txt` 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...` ##### Donations for Threadripper 3990x dream Bitcoin - 1gU9aQ2qqoQPuvop2jqC68JKZh5cyCivG
