<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 ... " -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 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.

   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

*   [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

*   [Python3](https://www.python.org/downloads/)

*   [Rav1e](https://github.com/xiph/rav1e) For Rav1e encoder
*   [SVT-AV1](https://github.com/OpenVisualCloud/SVT-AV1) For SVT-AV1 encoder

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...`
