Edge Crop¶

Description

This effect/filter removes pixels from the edges of the video (cropping).

Note

This filter is meant to be included as a normalizing filter attached automatically by the loader so that cropping occurs early in the processing stack and can request the full resolution of the source image. Then, a second instance of the filter may be applied to set the parameters of the crop operation.

Parameters

Parameter	Value	Description
Top	Integer	Number of pixels to be removed from the top edge
Left	Integer	Number of pixels to be removed from the left edge
Bottom	Integer	Number of pixels to be removed from the bottom edge
Right	Integer	Number of pixels to be removed from the right edge
Automatic center-crop	Switch	Whether to automatically crop whatever is needed to fill the output frame and prevent padding
Center balance	Integer	When center crop is enabled, offset the center point
Use project resolution	Switch	This is useful for proxy editing. Normally all crop values are expressed in terms of pixels of the source footage, but this option makes them relative to the profile resolution.

Warning

As of this writing and in version 23.04 this effect still behaves strangely. The parameter values seem to interfere with each other and it is not possible to have all four sides being cropped. It is either top/bottom or left/right and only the last value entered is applied (and then on both sides). Until this is fixed it is recommended to use the Crop, Scale and Tilt effect.
