Converting 1080p to 720p
I would like to use a avisynth script to do this but the issue is I need to readd the borders while keeping the same aspect ratio.
original is 1920x800 (borders cropped I am assuming just adding 140 top and bottom borders would make it full 1080p) But i want to downsize it to 720p. I would like to get a proportional 1280x??? with adding borders to make the ??? turn into 720. I have tried this but it seems to strech the picture so I am assuming the borders have to be bigger and the height smaller. Lanczos4Resize(1280,588).addborders(0,66,0,66) thanks for any help. ok doing some math which i am not good at it seems that correct proportions would be Lanczos4Resize(1280,534).addborders(0,93,0,93) am I correct?

It's very simple
1920/800 = 2.4 1280/2.4 = ~533 Lanczos4Resize(1280,534).addborders(0,93,0,93) so this line is correct
