<h2 align="center">Easy, Fast, and Efficient </h2>
|
|
|
|
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
|
|
|
|
<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)
|
|
Output file ending is always `.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 ... " -w 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 folders. Default: .temp
|
|
|
|
--boost Enable experimental CQ boosting for dark scenes. Refer to 1.7 release notes.
|
|
|
|
-bl CQ limit for boosting. CQ can't get lower than this value.
|
|
|
|
-br CQ range for boosting. Delta for which CQ can be changed
|
|
|
|
--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.
|
|
|
|
<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.
|
|
* 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](https://github.com/master-of-zen/Av1an/releases)
|
|
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](https://ci.appveyor.com/project/master-of-zen/av1an).
|
|
|
|
To ensure correct work 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 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
