ks-crop - Crop or change aspect ratio of a video.
=================================================
### Syntax:
* `$ ks-crop -16:9-crop <video-file> --> Crop from 4:3/IMAX to 16:9 (1.77:1)`
* `$ ks-crop -4:3-crop <video-file> --> Crop from 16:9 to 4:3 (1.33:1)`
* `$ ks-crop -5:4-crop <video-file> --> Crop from 16:9 to 5:4 (1.25:1)`
* `$ ks-crop -imax-crop <video-file> --> Crop from 16:9 to IMAX (1.43:1)`
* `.`
* `$ ks-crop -16:9-aspect <video-file> --> Change aspect to 16:9 (stretched)`
* `$ ks-crop -4:3-aspect <video-file> --> Change aspect to 4:3 (stretched)`
* `$ ks-crop -5:4-aspect <video-file> --> Change aspect to 5:4 (stretched)`
### Default configuration:
* The script `ks-crop` use by default the following configuration:
* `- Video codec: libx264`
* `- Bitrate video: 5000k`
* `- Preset: medium`
* `- Audio codec: copy`
* `- Default Audio: spa`
* `- Container: mkv`
* If you want to change the settings, you need to edit the `ks-crop` file and change the following variables:
* `v_preset="medium"`
* `vcodec="libx264"`
* `b_vcodec="5000k"`
* `acodec="copy"`
* `v_ext="mkv"`
* `default_lang_audio="spa"`
### Examples (Crop):
* Crop from 4:3/IMAX to 16:9 (1.77:1):
* `$ ks-crop -16:9-crop /data/movies/Example.mkv`
* Crop from 16:9 to 4:3 (1.33:1):
* `$ ks-crop -4:3-crop /data/movies/Example.mkv`
* Crop from 16:9 to 5:4 (1.25:1):
* `$ ks-crop -5:4-crop /data/movies/Example.mkv`
* Crop from 16:9 to IMAX (1.43:1):
* `$ ks-crop -imax-crop /data/movies/Example.mkv`
_Note: Output file name will be `Example-crop.mkv`._
### Examples (Change aspect):
* Change aspect to 16:9 (stretched):
* `$ ks-crop -16:9-aspect /data/movies/Example.mkv`
* Change aspect to 4:3 (stretched):
* `$ ks-crop -4:3-aspect /data/movies/Example.mkv`
* Change aspect to 5:4 (stretched):
* `$ ks-crop -5:4-aspect /data/movies/Example.mkv`
_Note: Output file name will be `Example-aspect.mkv`_
### Execution:
* After executing one of the mentioned commands, a wizard will be displayed to choose the video/audio tracks and define some parameters:
* `* Information of Example.mkv:`
* `.`
* `+ Video Tracks:`
* `Stream #0:0(eng): Video: h264 (High)`
* `.`
* `+ Audio Tracks:`
* `Stream #0:1(spa): Audio: dts (DTS)`
* `Stream #0:2(spa): Audio: ac3`
* `Stream #0:3(eng): Audio: ac3`
* `.`
* `* (Default: 0:0) Type the number of video track: `
* `* (Default: 0:1) Type the number of audio track: `
* `* (Default: 5000k) Type the bitrate (libx264): `
* `* (Default: n) Do you want apply '-max_muxing_queue_size 9999' patch? (y/n): n`
* `.`
* `* COMMAND THAT WILL BE EXECUTED:`
* `.`
* `# Crop 'Example.mkv' from 16:9 to 4:3 (1.33:1)`
* `ffmpeg -i Example.mkv -vsync 1 -async 1 -map 0:0 -map 0:1 -filter:v "crop=ih/3*4:ih" -s 1920x1440 -c:v libx264 -profile:v high -b:v 5000k -preset medium -c:a copy Example-crop.mkv`
* `.`
* `* (Default: y) Do you want run the conversion? (y/n): n`
