Start using AV1 encoding. All open-source encoders are supported (Aom, Rav1e, SVT-AV1).
2020-02-08 01:04:09 +00:00
Image to .ivf encoding supported (Aomenc, Rav1e)
2020-01-12 03:44:02 +00:00
Example with default parameters:
2020-01-13 16:55:07 +00:00
./av1an.py -i input
2020-01-12 03:44:02 +00:00
2020-01-13 14:07:26 +00:00
With your own parameters:
2020-01-12 03:44:02 +00:00
2020-02-17 13:34:53 +00:00
./av1an.py -i input -enc aom -e ' --cpu-used=3 --end-usage=q --cq-level=30' -vf ' scale=1280:-1 '
-t 10 -p 2 -a '-c:a libopus -b:a 24k' -s scenes.csv -log my_log -o output_file

2020-01-13 17:04:14 +00:00
-i --file_path Input file (relative or absolute path)
2020-02-14 06:42:25 +00:00
2020-01-16 08:23:40 +00:00
-o --output_file Name/Path for output file (Default: (input file name)_av1.mkv)
2020-02-14 06:42:25 +00:00
2020-02-01 16:24:35 +00:00

Example: -enc rav1e
2020-02-14 06:42:25 +00:00
-e --encoding_params Encoder settings flags (If not set, will be used default parameters.
2020-01-16 04:30:21 +00:00
Required for SVT-AV1s)
2020-01-27 18:55:00 +00:00
Can be set for both video and image mode
Must be inside ' ' or " "
2020-02-14 06:42:25 +00:00
2020-02-17 14:09:10 +00:00
-p --passes Set number of passes for encoding
2020-02-14 06:42:25 +00:00
(Default: Aomenc: 2, Rav1e: 1, SVT-AV1: 2)
At current moment 2nd pass Rav1e not working
2020-01-13 17:04:14 +00:00
-a --audio_params FFmpeg audio settings flags (Default: copy audio from source to output)
2020-02-03 23:09:23 +00:00
Example: -a '-c:a libopus -b:a 64k'
2020-02-14 06:42:25 +00:00
2020-02-17 13:25:33 +00:00
-t --workers Overrides automatically set number of workers.
Adjust accordingly to your system
2020-01-13 14:49:55 +00:00
Aomenc recommended value is YOUR_THREADS - 2 (Single thread per worker)
2020-02-14 06:42:25 +00:00
Rav1e and SVT-AV1 uses multiple threads,
2020-02-17 13:25:33 +00:00
Example: Rav1e settings ' ... --tile-rows 2 --tile-cols 2 ... ' -t 3
2020-02-14 06:42:25 +00:00
2020-02-06 00:43:33 +00:00
-s --scenes Path to file with scenes timestamps.
2020-02-07 23:25:04 +00:00
If given `0` spliting will be ignored
2020-02-06 00:43:33 +00:00
If file not exist, new will be generated in current folder
2020-02-14 06:42:25 +00:00
First run to generate stamps, all next reuse it.
Example: `-s scenes.csv`
2020-02-06 00:43:33 +00:00
-tr --threshold PySceneDetect threshold for scene detection
2020-02-14 06:42:25 +00:00
-ff --ffmpeg_com FFmpeg options. Example:
--ff ' -r 24 -vf scale=320:240 '
2020-01-26 20:58:45 +00:00
-fmt --pix_format Setting custom pixel/bit format(Default: 'yuv420p')
Example for 10 bit: 'yuv420p10le'
2020-02-17 13:22:34 +00:00
Encoding options should be adjusted accordingly.
2020-02-14 06:42:25 +00:00
--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
2020-02-17 13:22:34 +00:00
-m --mode 0 - Video encoding (Default),
1 - Image encoding. Using 10 bit encoding and constant quality mode Aom.
2020-01-22 08:54:10 +00:00
-log --logging Path to .log file(Default: no logging)
2020-01-13 14:07:26 +00:00

**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.
2020-01-12 03:44:02 +00:00
2020-02-16 16:19:37 +00:00
* [PySceneDetect ](https://pyscenedetect.readthedocs.io/en/latest/ ) used for spliting video by scenes and running multiple encoders.
2020-02-14 06:42:25 +00:00
2020-02-16 16:22:34 +00:00
* Both Video and Image encoding* (Single frame to .ivf, can be viewed by videoplayer).
2020-01-12 03:44:02 +00:00
2020-02-16 16:22:34 +00:00
* Resuming encoding without loss of encoded progress.
2020-01-27 18:04:36 +00:00
2020-02-16 16:22:34 +00:00
* Simple and clean console look.
2020-01-12 03:44:02 +00:00
2020-02-16 16:22:34 +00:00
* Automatic determination of how many workers the host can handle.
2020-01-12 03:44:02 +00:00
2020-02-16 16:22:34 +00:00
* Building encoding queue with bigger files first, minimizing waiting for last scene to encode.
2020-01-12 03:44:02 +00:00
2020-02-16 16:22:34 +00:00
* Both video and audio encoding option with FFmpeg.
