Bizarre AR from AutoGK

[richarddd]

I used AutoGK 1.6 on the DVD for The Piano. In the resulting avi, a few scenes came out widescreen and the rest full screen. Neither the WS nor the FS looked distorted.

The DVD has two sets of VOBs, one WS and one FS. In both sets, the openning logo is FS. DVD Decrypter creates the same stream info file for each set, listing the AR as 4:3, although the WS should be 1.85:1.

Any suggestions?

Seems I can only attach one jpg per message

This is the start logo

This is WS a few minutes later

and this is FS a few minutes later [edited to change WS to FS]

I see nothing wrong as you should see the same picture on DVD itself.

Yeah, it's a funky DVD, but that's not AutoGK's fault. As near as I can tell, AutoGK did a pretty good job with it.

...listing the AR as 4:3, although the WS should be 1.85:1.

Actually, you're both right. The widescreen version is widescreen letterboxed (non-anamorphic) 4:3, not a good combination for good quality DVDs. The movie deserves better. For a better understanding of DARs, read Doom9's Article (http://www.doom9.org/aspectratios.htm), particularly the paragraph beginning, "There are also DVDs which have a DAR of 4:3 but contain widescreen picture."

And here's what IMDB has to say about it:

LenOx, the DVD is either FS or WS, not a combo.

I agree with IMDB's assessment.

When all else fails, try again. I re-booted, re-rippred with DVD Decrypt and re-compressed with AutoGK. This time the entire movie was WS. I have no idea how I or AutoGK managed to get both FS and WS for the first attempt. stream-info shows 4:3. AutoGK chose 608x336 (AR 1.81).

btw, thank you for an excellent program. I've recently used AutoGK on about 30-40 movies and have had only two problems, this and the lack of subtitles on Grand Illusion (perhaps caused by not turning on the angle setting in DVDDecrypter, although there was only one angle; oddly, log file showed a 164432 ms delay for subs and *.sub file was 0 bytes; I'll try again). Anyway, thanks much.

I have no idea how I or AutoGK managed to get both FS and WS for the first attempt.

The 3 pictures you showed are consistent with a Pan-And-Scan Fullscreen version of the movie (despite what I see as a typo for the 3rd picture saying, "This is WS a few minutes later", when it's clearly a Fullscreen picture.

Oops - you're right (I'll edit).

btw, turning on angle and pgc, as described in the faq, fixed the sub problem. Another victory for RTFM :)

Hi.

While I was watching Jurassic Park in the movie theater, I saw that the picture-area AR differed, the height became less in the dinosaur special effects scenes. It wasn't noticeable unless you have the AR bug in your head.

The same thing goes for DVDs too. I have noticed this in many DVDs.

I believe what happens is this. The camera crews aren't the same. In Jurassic Park, for example, the special effects were generated in the Industrial Light and Magic labs. Another crew shot the ordinary scenes with Mr Spielberg. That could be the reason for the slight AR variations.

If such is the case in a DVD, then AGK will keep both of them; it will not crop away from the larger-height frames to make them at par with the lesser-height ones.

Regards.
