Ah, I remember this. Thank you. I guess it makes sense that DVD was made to be as compatible as possible with older equipment.kei17 wrote: ↑Sun May 31, 2020 2:27 pmDVD follows the standards of the DV videotape format. It stores video footage in 720x480, which is shown on TV in 10:11 pixel aspect ratio. 704 out of 720 horizontal pixels are actually visualized, so the eight pixels on each side are redundant and not meant to be shown on TV. You can get proper 4:3 footage by cropping 16 pixels horizontally before resizing DVD footage to 4:3 screen aspect ratio. A lot of videos and images available online are resized incorrectly by not cropping these redundant pixels, so they are slightly squashed. In other words, don't directly resize 720x480 footage to 4:3 resolutions like 720x540. If you don't want to lose these pixels, resize it to resolutions based on 10:11 pixel aspect ratio such as 720x528 (720x1=720, 480x1.1=528).
Do HDTVs generally honor the 10:11 pixel aspect ratio? I know that software media players generally don’t, because the whole 720x480 image is mapped to a 4:3 box.
If a DVD does not have 8 pixels of black on each side, is it more likely that it it will display slightly squashed on older TV sets, or that they included a picture slighty wider than 4:3?
