# Description
Re-encode video files to AV1 with ffmpeg. The primary use case for this
script is to re-encode video files with a very high bitrate to a more
compact format. The default settings will reduce the bitrate by 30%
# Examples
### Re-encode all videos in a dir
Note: The original files will be removed unless -b is specified
```sh
python av1encoder.py -i ./videos
```
### Re-encode multiple videos and copy originals to a backup dir
```sh
python av1encoder.py -b -i ./videos/video1.webm ./videos/video2.webm
```
### Reduce bitrate by 50%, backup original, do not go below 2M bitrate
```sh
python av1encoder.py -i /tmp/input.webm -s 0.5 -b -mn 2
```
# Flags
```
-i INPUT [INPUT ...], --input INPUT [INPUT ...]
Input files or directories. Directories will not be searched recursively. Only video
files with known extensions will be processed.
```
```
-s SHRINK, --shrink SHRINK
Shrink bitrate by default=0.30. i.e 30 percent
```
```
-p PRESET, --preset PRESET
Preset. 0-13. Higher = Faster default=8
```
```
-a AUDIO, --audio AUDIO
Audio codec setting. You can write any ffmpeg flags here and they will be inserted into
the final command. default=-c:a copy
```
```
-b, --backup, --no-backup
Backup original files. If this is set, a backup folder will be created and the original
files will be copied there. (default: No backup)
```
```
-mx MAX_VIDEO_BITRATE, --max_video_bitrate MAX_VIDEO_BITRATE
Max video bitrate in Mbps. default=45. 100 is the max
```
```
-mn MIN_VIDEO_BITRATE, --min_video_bitrate MIN_VIDEO_BITRATE
Min video bitrate in Mbps. default=1
```
```
-x EXTENSION, --extension EXTENSION
Specify output extension. default=mp4
```
