I like the actual system, even a simpler one. What kills me is cropping it
"visually" and so stretching the image.
From the user perspective another option can be: select
the source pixel
aspect ratio for stretching, the target format, and manually adjust
zoom.
Add a vertical offset to compensate for subtitles on black or minimal
pan&scan, and magic! :D
To the Magnus list, add the NTSC SD formats, and you get an even longer and
evergrowing list of formats. (NTSC SD scope letterboxed: 268 pixels of
height... I projected that last week)

In my (swedish) everyday work these situations are the
most common:
*

*Square pixels:*
*HD 16:9.* 1920 x 1080 -> 1920 x 1080
*HD 1:1,85* 1920 x 1038 -> 1998 x 1080
*HD 1:1,66* 1793 x 1080 -> 1793 x 1080
*HD 1:1,37* 1480 x 1080 -> 1480 x 1080
*HD 4:3* 1436 x 1080 -> 1436 x 1080
*HD scope.* 1920 x 803 -> 2048 x 858
*SD 4:3 768 x 576* -> 1436 x 1080
*SD 16:9 letterboxed* 768 x 431 -> 1920 x 1080
*SD scope letterboxed* 760 x 321 -> 2048 x 858 (nasty)
*Non square pixels:*
*SD 16:9 anamorfic* 768 x 576 -> 1920 x 1080
The numbers are calculated on my cellphone, please correct me if necessary.
Another alternative might be a checkbox "square pixels" combined with a
sort of zoom or "fill aspect FLAT/SCOPE" function.
What I´m aimaing at is a scaling option that makes incoming picture fit
into outgoing FLAT or SCOPE *without* any stretching or cropping.
Stretching or cropping should be an active choice from the operator
(assuming that he or she knows the consequences)
Some scope films has burned subtitles in the black bar. A "manual" or
"custom" choice would be necessary to handle those.
