09:38 < bemasc> emdash: So, the true parameters here are the storage height,
storage width, PAR, and DAR.
09:39 < bemasc> that's 4 values in total, but only 3 degrees of freedom.
09:40 < bemasc> Personally, I would expose all 4, and update PAR after each change to DAR (and vice versa)
How about this, then?
I'm actually not so sure that DAR and PAR should update each other, as I played around with it and it's somewhat frustrating. I think most of the time you're either targeting a specific format (for example, 480i) in which case you'd just choose a preset, or you'll be working with square pixels.
I think i need to add a 'constrain aspect ratio' check-button to make scaling a bit easier.
