- Were you looking for croppadd, the current module?
| Module: Crop | |
|---|---|
| Type | Video filter |
| First VLC version | - |
| Last VLC version | 2.0.9 |
| Operating system(s) | all |
| Description | Remove borders of the video and replace them with black borders |
| Shortcut(s) | - |
Options
- crop-geometry <string> : Set the geometry of the zone to crop. This is set as
<width> × <height> + <left offset> + <top offset> - autocrop <boolean> : Automatically detect black borders and crop them default value: disabled
- autocrop-ratio-max <integer [0 .. 15000]> : Maximum image ratio. The crop plugin will never automatically crop to a higher ratio (ie, to a more "flat" image). The value is ×1000: 1333 means 4⁄3 default value: 2405
- crop-ratio <integer [0 .. 15000]> : Force a ratio (0 for automatic). Value is ×1000: 1333 means 4⁄3 default value: 0
- autocrop-time <integer> : The number of consecutive images with the same detected ratio (different from the previously detected ratio) to consider that ratio changed and trigger recrop default value: 25
- autocrop-diff <integer> : The minimum difference in the number of detected black lines to consider that ratio changed and trigger recrop default value: 16
- autocrop-non-black-pixels <integer> : The maximum of non-black pixels in a line to consider that the line is black default value: 3
- autocrop-skip-percent <integer [0 .. 100]> : Percentage of the line to consider while checking for black lines. This allows skipping logos in black borders and crop them anyway default value: 17
- autocrop-luminance-threshold <integer [0 .. 128]> : Maximum luminance to consider a pixel as black (0-255)* default value: 40
Note
This must be a typo. Despite the claim of a range of 0-255 in the help text for the --autocrop-luminance-threshold option, the call to add_integer_with_range would have limited this to effectively 0-128.
