Why resolution change in Handbrake with “keep aspect ratio” checked?
“I’m converting most of my DVDs to digital files, and I don’t understand why when I see source showing “720 x 480”, and I have “Keep Aspect Ratio” checked, the size on every movie changes; primarily the height changes from movie to movie. Is this cropping detecting that the movie height isn’t really 480?”
Solution to fix Handbrake Aspect Ratio Distored Problem when ripping DVD
Solution 1: Change Anamorphic setting
Change your settings from “Anamorphic: None” to “Anamorphic: Strict”. Then the output video will strictly follow with the original file size.
Solution 2: Manually set frame size as original
When encoding from DVD or a VIDEO_TS folder, Handbrake would spot the mismatch (2.37:1 stream vs. 1.78:1 container) and would defer to the container’s setting. If you use “Anamorphic: None”, disable “Keep Aspect Ratio” (since the reported PAR is wrong) and manually set the frame size to 720×480.
