Hey all, wanted to share this before I forget:
It has some AVFoundation niceness so you can skip around the timeline really responsively, randomise playhead position etc, then screen grab with a single key.
There are two modes: CROP and RESIZE, which use the ratio of the window to either: crop or toggle. The pixel size of the window won’t effect the output resolution, and the app will work out the most “non-destructive” resolution to output as (ie. longest side).
To change the ratio (4:3, 16:9, etc) press 1 - 6
To toggle CROP / RESIZE press Tab
To take a screen grab press C (outputs to the Desktop)
To randomise press R
And to skip around on the timeline, press LEFT and RIGHT (and with SHIFT)
That’s about it! In theory it should compile to Windows, Linux too though I don’t have those machines to hand right now.
