### Process all videos from a channel
_To get the channel id if it only has a username, run the JS code in the browser console:_
```javascript
document.querySelector("body>link").href
```
**Then, in the input parameter,
you can pass a link to the channel (with an id, not with a username) or a string of the format "c/CHANNEL_ID"**
_For example:_
> python -m fastdub -i "c/[UCi-5OZ2tYuwMLIcEyOsbdRA](https://www.youtube.com/channel/UCi-5OZ2tYuwMLIcEyOsbdRA)" -yt
## YouTube Search argument group
That the input data was a request to YouTube, they must begin with "?".
_For Example:_
> python -m fastdub -i "?#python" -yt -yts-l 5
## YouTube Upload argument group
> pip install FastDub[YTU]
To download, you need to go to [credentials](https://console.cloud.google.com/apis/credentials) (Create a new project if
needed) > <kbd>+ Create credentials</kbd> > <kbd>OAuth Client ID</kbd> > <kbd>Desktop App</kbd>
After filling in the required fields, <kbd>DOWNLOAD JSON</kbd> format and save to a working folder under the name
_client_secrets.json_
* Specifying the -ytu-ps argument as non-private may result in processing errors, but this was not observed during
testing.
* Please note that video uploads require a large amount of [quota](https://console.cloud.google.com/iam-admin/quotas) (
default has 10,000 per day)

# CHANGELOG
# 3.8.0
## General
- `changelog` has been translated into English.
- Added `logging.error`
## FFmpeg Wrapper
- `ffmpeg_wrapper` module objects renamed according to PEP-8
(`FFMpeg` to `FFmpeg`)
## Translator
- `translator.get_service_by_name` is now a valid function even if required dependencies are not installed, in which
case if call it will raise `KeyError`
## YouTube
- dependency `pafy` added to `extra_requires/requires_yt.txt`
# 3.7.0
## General
- **Changed minimum supported Python version from 3.8 to 3.9**
## CLI
- Fixed bug with `logging.getLevelNamesMapping()` in `__main__.py`
# 3.6.0
## General
- Package `logging` used
- Bugfix
- optimization
## Audio Processing
- `sidechain` is now much faster using `ffmpeg`
## FFmpeg Wrapper
- The `ffmpeg-imageio` library is no longer used, instead the `ffmpeg` command is always called
## CLI
- Argument `--sidechain-ffmpeg-params` see [FFmpeg Documentation](https://ffmpeg.org/ffmpeg-all.html#sidechaincompress)
- Separate `--sidechain-level-sc` see `level_sc` higher.
- `-ll` is now program loglevel and ffmpeg loglevel is now `-fll`
# 3.5.2
## Translator
- Now it will not cause an error in the absence of the Internet.
## Subtitles
- Fixed possible .srt format differences (now `.` is allowed instead of `,`)
# 3.5.1
## Subtitles
- Fixed possible problems with different encodings (added `chardet` module)
# 3.5.0
## Voiceover Process
- Added argument `--export-video` (`-ev`): `BooleanOptionalAction` if `False` (`--no-export-video`, `-n-ev`)
only exports audio
# 3.4.2
- Minor improvements and optimizations.
## Subtitles
- The `TimeLabel` class is no longer a subclass of `Line`
# 3.4.1
- Fixed documentation
# 3.4.0
## General
- Added the ability to apply a watermark to the video (see the `--watermark` argument)
## CLI
- Bugfix
- The `--watermark` argument. The text of the watermark is passed to it.
- Now, when launched from the console, the FastDub mini-banner is shown.
## Voiceover Process
- Bugfix
- Now fitted audio (which starts with '_') is always deleted as it's a temporary file
## FFmpeg Wrapper
- Added class method `FFmpegWrapper.get_video_duration_s`
which is used in `FFmpegWrapper.get_video_duration_ms`
- The video result includes: dubbed audio, original audio, subtitles, original subtitles (if any)
## Submodules
### Translator
- The latest version of the translators module is now used
# 3.3.0
## General
- Implemented class `GlobalSettings`
## Audio Processing
- The `calc_speed_change_ffmpeg_arg` function for calculating the `-af` ffmpeg argument
for speed change has been changed.
- Significantly accelerated using a different algorithm.
- Optimized `side_chain` function.
## Voiceover Process
- Audio length trimming and TTS are now combined into one process to increase performance.
- Now a subfolder `_result_working_dir` is created in which separate already fitted subtitle lines are saved, after
which all parts are glued together with ffmpeg.
Due to this, memory consumption is significantly reduced.
- `moviepy` is no longer a dependency, ffmpeg output is parsed instead
## FFmpeg Wrapper
- Now all arguments are converted to strings before calling `check_call`
# 3.2.0
## CLI
- Omitted optional `type=str` arguments.
- Changed `BooleanOptionalAction` logic, both `--no-` and `-n-` negation are now available.
- The `--cleanup-audio` argument is now `BooleanOptionalAction` (default `True`), `--cleanup-level` has been removed.
- Argument `--voice-set-anchor` (also `!:` by default).
- `--audio-format` argument for output audio (default `wav`).
- The `--sidechain` argument has been renamed to `--side-chain`.
- Added shorthand to `--traceback` argument - `-tb`.
## Voiceover Process
- Bugfix.
- Optimization of track length fitting (Fitting).
## TTS
- `anchor` argument (see `--voice-set-anchor`).
- Voice change optimization.
## Submodules
### YouTube
- When multi-loading, fully loaded videos are removed from the screen (so as not to take up space in vain).
