Many videos I get are with black bars on the top or bottom.
"With the power of Adobe Sensei", detect black bars, crop the video, save in the same format and quality.
It can be a preset, it can be a checkbox in a preset or it can be a script.
optional: add a XX pixels inset from the crop for sharper edges.
It must be "drag, run, see folder". If so, it can be a killer feature.
