Hi Madshi,
Thanks so much for the awesome software - it's truly world class.
I would like to propose a couple of tweaks to zoom control if it's not too bold;
1. Change the "reduce bar size" option from a drop-down to a numeric where we can enter any percentage (25% is often a bit low whereas 50% can sometimes be severe)
2. If it's possible to detect scene changes (not sure - don't think a simple wait for an I-frame would do) it would be great to initiate zoom on a scene change so it's not noticeable to the user. This way movies that change aspect ratio (eg. IMAX titles like Interstellar/The Dark Knight) could become a seemless blend of full-frame and zoomed content.
If it's not too much work I think these would improve the zoom control experience
Thanks again!
