How to zoom to a user-selected rectangle

Help/How To

I have just started learning Shotcut, and I now know how to crop a video (using crop:rectangle). I’m not fully satisfied with the result because the cropped extract
is shown on top of a black brangound and I would like to remove that black background, with the cropped part filling all the available space. So the zoom functionality seems better suited for what I need. But so far, the only way I found to zoom is to change the percentage in the zoom bar :

This is awkward and inconvenient, as it will either keep a part that I don’t want or leave out a part that I want. Trial with other parameters (such as “horizontal fit” or “vertical fit”) allows me to mitigate this, but I’m looking for a more systematic and clean way to do this.

Perhaps there is an option when using crop:rectangle, to remove the surrounding black background around the video ?

You can use the Moving Handle in the preview window to drag the image in any direction after you zoom.

The latest version (23.09.13) has a new filer called Reframe (see tutorial here) which you might like if you don’t mind outputting any non-standard rezolution/size.

Alternatively, there’s also the Crop:Source filter which you can cut any number of pixels from each side of the image and it will automatically zoom it to best fit the current rezolution.
