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=-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)
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 Default: 30
-ff --ffmpeg FFmpeg options. Applied to each segment individually
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)
--temp Set path for temporally forlders. Default: .temp
--boost Enable experimental CQ boosting for dark scenes. Refer to 1.7 release notes.
-bl CQ limit for boosting.
-br CQ range for boosting.
--vmaf Calculate vmaf for each encoded clip.
Requires: Installed FFMPEG with libvmaf and installed libvmaf.
--vmaf_path Custom path to libvmaf models, by default used system one.
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 used for spliting video by scenes and running multiple encoders.
- Fastest way to encode AV1 without lossing 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 scenes based on their brightness.
Install on Windows
1. Use ready Release
With every release included archive that have all needed executables.
No extra installation of dependencies is needed.
Just unpack it to desired folder and use cmd or powershell
to execute av1an.exe all_params
Autobuilding .exe from current git available at AppVeyor.
To ensure correct work all .exe for ffmpeg, and encoders should be in same folder.
2. Install with dependancies
All .exe for ffmpeg and encoders should be in same folder or
be accesable through PATH
Install all python 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
Install all python requirements listed in requirements.txt file with pip install -r requirements.txt
Optionally add Av1an to your PATH
Run with command: av1an.py params...
