Stretch detection?

Happy you found a way. Smile

I think that main problem seems to be that you seem to mix the different aspect ratio definitions. Smile
-> May be reading [INFO] About pixel aspect ratios,.. and the sources linked in that thread help a bit.

My usual approach when getting a source with wrong aspect ratio is:
  • load source
  • search for a scene where a square or round object is shown that allows me to see the effect of different aspect ratios
  • adjust the input PAR (=pixel aspect ratio) so that the observed object looks proper. (testing the standard PARs is usually a good start)
  • crop the content (= remove all black bars); this does now change the pixel aspect ratio.
  • decide what output PAR (=pixel aspect ratio) the output should have
  • if the output PAR (=pixel aspect ratio) should differ from the input PAR (=pixel aspect ratio) I enable 'Convert to PAR' and specifiy the PAR (=pixel aspect ratio) I want for the output. This automatically enabled the 'Resize', since now it's time to decide the pixel count of the output.
  • now I decide the count of pixels in width and height the output picture has (the storage aspect ratio).
  • To archive the SAR I want, I
    1. keep the 'Auto adjust' in the 'Picture Resize' active since it makes sure that the output does not get distorted.
    2. I set 'Auto adjust' to either 'height' or 'width' and specify either my target width or target height.
    3. To lastly archive the storage aspect ratio I want I enable letter box and enter my storage width and storage height.

-> Hope the link above and this helps a bit for the future.
