Of course I’m brand new to Shotcut so here come the dumb questions.
This is more of a curiosity question. When I load a video, it seems to come in at 50% zoom, which includes the entire video frame, with the black bars on either side. Setting the zoom to 100% shows a closer cropped view. Seems like the 100% view would be showing the entire video frame. All videos are records at 1080p 24 fps.
So I set the zoom to 100 and then export. One out of 4 times, it kept the zoom.
The Frame Grab also does the same thing.
There is no real need to set a name, but if you ever wanted to use this same setting again, you could recall it. Settings → Video Mode → Custom → named preset
Example:
If you want a 1920x1080 video, leave the video mode resolution the same, but change the FPS to match.
You would need to apply either a Crop: Source (Center checked) filter, or a Size, Position & Rotate with zoom to not have black bars. There is also a Distort setting. This morphs your video clip to the video mode resolution.
