## Supported Formats
Subtitle: SubRip, TTML, WebVTT, (Advanced) SubStation Alpha, MicroDVD, MPL2, TMP, EBU STL, SAMI, SCC and SBV.
Video/Audio: MP4, WebM, Ogg, 3GP, FLV, MOV, Matroska, MPEG TS, WAV, MP3, AAC, FLAC, etc.
:information_source: <small style="line-height: 1.2;">Subaligner relies on file extensions as default hints to process a wide range of audiovisual or subtitle formats. It is recommended to use extensions widely acceppted by the community to ensure compatibility.</small>
## Dependencies
Required by basic: [FFmpeg](https://www.ffmpeg.org/)
```
$ apt-get install ffmpeg
```
or
```
$ brew install ffmpeg
```
## Basic Installation
```
$ pip install -U pip && pip install -U setuptools
$ pip install subaligner
```
or install from source:
```
$ git clone git@github.com:baxtree/subaligner.git && cd subaligner
$ pip install -U pip && pip install -U setuptools
$ python setup.py install
```
:information_source: <small style="line-height: 1.2;">It is highly recommended creating a virtual environment prior to installation.</small>
## Installation with Optional Packages Supporting Additional Features
```
# Install dependencies for enabling translation and transcription
$ pip install 'subaligner[llm]'
```
```
# Install dependencies for enabling forced alignment
$ pip install 'subaligner[stretch]'
```
```
# Install dependencies for setting up the development environment
$ pip install 'subaligner[dev]'
```
Note that both `subaligner[stretch]` and `subaligner[dev]` require additional dependencies to be pre-installed:
```
$ apt-get install espeak libespeak1 libespeak-dev espeak-data
```
or
```
$ brew install espeak
```
To install all supported features:
```
$ pip install 'subaligner[harmony]'
```
## Container Support
If you prefer using a containerised environment over installing everything locally, run:
```
$ docker run -v `pwd`:`pwd` -w `pwd` -it baxtree/subaligner bash
```
For users on Windows 10: [Docker Desktop](https://docs.docker.com/docker-for-windows/install/) is the only option at present.
Assuming your media assets are stored under `d:\media`, open built-in command prompt, PowerShell, or Windows Terminal and run:
```
docker pull baxtree/subaligner
docker run -v "/d/media":/media -w "/media" -it baxtree/subaligner bash
```
## Usage
```
# Single-stage alignment (high-level shift with lower latency)
$ subaligner -m single -v video.mp4 -s subtitle.srt
$ subaligner -m single -v https://example.com/video.mp4 -s https://example.com/subtitle.srt -o subtitle_aligned.srt
```
```
# Dual-stage alignment (low-level shift with higher latency)
$ subaligner -m dual -v video.mp4 -s subtitle.srt
$ subaligner -m dual -v https://example.com/video.mp4 -s https://example.com/subtitle.srt -o subtitle_aligned.srt
```
```
# Generate subtitles by transcribing audiovisual files
$ subaligner -m transcribe -v video.mp4 -ml eng -mr whisper -mf small -o subtitle_aligned.srt
$ subaligner -m transcribe -v video.mp4 -ml zho -mr whisper -mf medium -o subtitle_aligned.srt
```
```
# Alignment on segmented plain texts (double newlines as the delimiter)
$ subaligner -m script -v test.mp4 -s subtitle.txt -o subtitle_aligned.srt
$ subaligner -m script -v https://example.com/video.mp4 -s https://example.com/subtitle.txt -o subtitle_aligned.srt
```
```
# Alignment on multiple subtitles against the single media file
$ subaligner -m script -v test.mp4 -s subtitle_lang_1.txt -s subtitle_lang_2.txt
$ subaligner -m script -v test.mp4 -s subtitle_lang_1.txt subtitle_lang_2.txt
```
```
# Alignment on embedded subtitles
$ subaligner -m single -v video.mkv -s embedded:stream_index=0 -o subtitle_aligned.srt
$ subaligner -m dual -v video.mkv -s embedded:stream_index=0 -o subtitle_aligned.srt
```
```
# Translative alignment with the ISO 639-3 language code pair (src,tgt)
$ subaligner --languages
$ subaligner -m single -v video.mp4 -s subtitle.srt -t src,tgt

$ docker run -it baxtree/subaligner subaligner -m dual -v https://example.com/video.mp4 -s https://example.com/subtitle.srt -o subtitle_aligned.srt
```
The aligned subtitle will be saved at `subtitle_aligned.srt`. For details on CLIs, run `subaligner -h` or `subaligner_batch -h`, `subaligner_convert -h`, `subaligner_train -h` and `subaligner_tune -h` for additional utilities. `subaligner_1pass` and `subaligner_2pass` are shortcuts for running `subaligner` with `-m single` and `-m dual` options, respectively.
## Advanced Usage
You can train a new model with your own audiovisual files and subtitle files:
```
$ subaligner_train -vd VIDEO_DIRECTORY -sd SUBTITLE_DIRECTORY -tod TRAINING_OUTPUT_DIRECTORY
```
Then you can apply it to your subtitle synchronisation with the aforementioned commands. For more details on how to train and tune your own model, please refer to [Subaligner Docs](https://subaligner.readthedocs.io/en/latest/advanced_usage.html).
## Anatomy
Subtitles can be out of sync with their companion audiovisual media files for a variety of causes including latency introduced by Speech-To-Text on live streams or calibration and rectification involving human intervention during post-production.
A model has been trained with synchronised video and subtitle pairs and later used for predicating shifting offsets and directions under the guidance of a dual-stage aligning approach.

## Supported Formats
Subtitle: SubRip, TTML, WebVTT, (Advanced) SubStation Alpha, MicroDVD, MPL2, TMP, EBU STL, SAMI, SCC and SBV.
Video/Audio: MP4, WebM, Ogg, 3GP, FLV, MOV, Matroska, MPEG TS, WAV, MP3, AAC, FLAC, etc.
:information_source: <small style="line-height: 1.2;">Subaligner relies on file extensions as default hints to process a wide range of audiovisual or subtitle formats. It is recommended to use extensions widely acceppted by the community to ensure compatibility.</small>
## Dependencies
Required by basic: [FFmpeg](https://www.ffmpeg.org/)
```
$ apt-get install ffmpeg
```
or
```
$ brew install ffmpeg
```
## Basic Installation
```
$ pip install -U pip && pip install -U setuptools
$ pip install subaligner
```
or install from source:
```
$ git clone git@github.com:baxtree/subaligner.git && cd subaligner
$ pip install -U pip && pip install -U setuptools
$ python setup.py install
```
:information_source: <small style="line-height: 1.2;">It is highly recommended creating a virtual environment prior to installation.</small>
## Installation with Optional Packages Supporting Additional Features
```
# Install dependencies for enabling translation and transcription
$ pip install 'subaligner[llm]'
```
```
# Install dependencies for enabling forced alignment
$ pip install 'subaligner[stretch]'
```
```
# Install dependencies for setting up the development environment
$ pip install 'subaligner[dev]'
```
Note that both `subaligner[stretch]` and `subaligner[dev]` require additional dependencies to be pre-installed:
```
$ apt-get install espeak libespeak1 libespeak-dev espeak-data
```
or
```
$ brew install espeak
```
To install all supported features:
```
$ pip install 'subaligner[harmony]'
```
## Container Support
If you prefer using a containerised environment over installing everything locally, run:
```
$ docker run -v `pwd`:`pwd` -w `pwd` -it baxtree/subaligner bash
```
For users on Windows 10: [Docker Desktop](https://docs.docker.com/docker-for-windows/install/) is the only option at present.
Assuming your media assets are stored under `d:\media`, open built-in command prompt, PowerShell, or Windows Terminal and run:
```
docker pull baxtree/subaligner
docker run -v "/d/media":/media -w "/media" -it baxtree/subaligner bash
```
