How were you thinking it should be handled? At the moment it looks at
pixel aspect ratio and chooses the "best" ratio with respect to that.
I guess I had something in my mind like keeping the aspect ratio from the pixel AR flag
always present when dealing with the file, or, always convert to square pixels first, then
let the user choose a scaling. But as I have no idea of DCP-o-matics internal handling of
this, this may not be feasible. The way you did it solves 16:9 default scaling, and that
should be it for now, as this is the most common need to deal with non-square pixels.
Yes, I think it's a good idea to get rid of the default scale pref. The best way to
deal with this by default is to
- handle the correct aspect ratio of the content file when scaling
- scale it full screen according to DCI specs to either container hight or width
Whoever then needs different options, has to set them manually.
Of course, there is no easy way to deal with this when we have letterboxed content like
1.85 or 2.39 from BluRay or DVD. Wondering wether these files actually carry a
'letterboxed' or 'visible content in lines x-y' indicator? That would be
handy.
