VLC snapshot incorrect res on DVD VOB's

[oddball]

When I screencap using VLC from VOB files it saves them as a weird resolution (853x480) plus puts black borders around the video. Using snapshot on AVI files etc it captures correctly.

Any ideas?

Example image from a DVD VOB.

Well, I can't really see a problem looking at your image - I'm quite sure the black borders are part of the DVD (in the overscan portion of the image that usually isn't visible on a TV), and the resolution is 720x480 anamorphically stretched for 16:9 (yeah, it's not mod 4 or anything, but PNG doesn't care) - if it weren't your image would look squished horizontally...

Now I'm just confused :)

Anamorphic video is not encoded at the same aspect ratio as it is intended to be viewed. Therefore the video needs to be "stretched" at playback time to look correctly. So while the video is encoded at 720x480, it needs to be viewed at 853x480. Otherwise you would get a squished picture, as Leak said. Furthermore it's perfectly normal to have some "black" area at the borders of the video, because the TV screens will crop the borders anyway. This is called "overscan".

Well, I doubt your AVI files are anamorphic (i.e. with a display aspect ratio that makes the player stretch the video before displaying it) and usually people crop off any extra border when they encode - the border on DVDs is usually there because the video's dimensions have to be 720x480 or 704x480...

Well there you go and I thought I had anamorphic all worked out. :)
