Thanks!
I wanted to reply on the thread you linked because I wanted to ask something about it, but it seems like the ability to reply is disabled there, so I'll ask it here.
If I understand it correctly, PAR is the width and height of each pixel, SAR is the width and height of the source video without PAR applied, a.k.a. if the video used a PAR of 1:1, and DAR is the result of displaying the video with the intended resolution.
Is PAR a thing for image files? I suppose not?
I noticed that when I make a snapshot of a PAL DVD video that's playing in media player MPC-HC, where the displayed resolution was 768x576, the saved snapshot would be 720x576. I assume this is the "storage resolution". However, when I take a snapshot in VLC, I actually do end up with a 768x576 image. Since this second snapshot does in fact have a greater width and doesn't seem to have a different PAR, I assume this image, while staying truthful to the DAR, will have some quality loss, since it's basically resized from the storage resolution.
