Aspect ratio detected both correctly and incorrectly(?)

[Sven Viking]

When loading an IFO file, AutoGK will sometimes list a 4:3 aspect ratio in the Video Info box, e.g.:
Video info: MPEG2 720x576 PAL 4:3 PGC 1. Length: 0:48:44:11

When encoding is started, however, the log window reports:
[1/04/2009 9:58:04 AM] Processing file: I:\VIDEO_TS\VTS_02_2.VOB
[1/04/2009 9:58:04 AM] Source resolution: 720x576
[1/04/2009 9:58:04 AM] Found PAL source.
[1/04/2009 9:58:04 AM] Source aspect ratio: 16:9
...
[1/04/2009 9:58:28 AM] Chosen resolution is: 768x448 ( AR: 1.71 )

(And the resulting files do have an obviously incorrect aspect ratio). I've had this problem with several different DVDs. Output Resolution is set to Fixed Width: 768. Codec is XVID. Edit: Using AGK version 2.55.

Setting a manual aspect ratio of 4:3 in Hidden Options solves the problem (though the files have to be copied to the hard disc first so the .aspect file can be created in the source folder). Seeing as the Video Info box correctly reports "4:3", though, I'm guessing this is a bug of some sort(?)

Despite your statement that "the resulting files do have an obviously incorrect aspect ratio," do the end files at 16:9 look correct or are the images stretched horizontally?

It's not unheard of for the IFOs to have one DAR and the encoded VOBs the other. Since most DVD players get the DAR from the IFO, then the DVD will play properly. In such cases where the VOB DAR is incorrect, go into the Hidden Options (CTRL-F9) and change it.

And welcome to the forum.

CWR03: Yes, the resulting files are notably stretched at 16:9. They display in 4:3 when played in a DVD player.

manono: OK, thanks for the information.
