TRIMCROP

Qt6/QML app to trim and crop videos on desktop.

About

Provides a visual interface to ffmpeg¹.

Saving the video sends all the information configured on the front end(i.e. trim positions, information about the crop selection area) to ffmpeg, which is ultimately responsible for the actual transcoding. To do this, I exposed the QProcess class & a few of it's methods to QML², defined the command I wanted to run³, and wait⁴ for ffmpeg to finish the heavy lifting.
