Post by (PeteCresswell)Post by (PeteCresswell)When I rip a certain movie, I see what appear tb two copies of
the Main Movie. viz: http://tinyurl.com/4ys7p2c.
And, after the rip, when I go to convert it to .MPG via VideoReDo
TV Suite; VideoRedo throws "Warning! The selected title contains
multiple angles. VideoReDo does not currently support
multi-angle DVDs and opening this title could cause unexpected
behavior....."
Sounds like I should have somehow told the ripper app to convert
only "Angle 1".... but there's still a new concept here.
Can anybody explain?
Without anymore info (or actually having the DVD in-hand) I can only venture
a guess. But first... are you suggesting you have no clue that a DVD can
have multi-angle video? It hasn't been used much and I believe it hasn't
really ever been exploited to it's full potential (to much money for a
motion picture studio to shell out to hire multiple camera crews) but
non-the-less the mechanism is there.
You may *think* you have two copies of the same exact thing but I doubt
that's what you got. Run both copies at the same time and look for
differences or look on the DVD for a menu item that may say "alternate
ending" or "directors cut".
The last couple times I ran into multi-angles on DVD it was used two
different ways.
The first was a animated film by a company that has a mouse as a mascot, of
a an old man and a boy that floated a house by balloon to South America
("it's like America BUT SOUTH"!!). That DVD used multi-angle only at
predetermined times to put up (no pun intended) credits in whatever
language you chose to watch the film. If you where watching with a Spanish
audio track, the title and the credits were written in Spanish, for
example.
The other was a super-duper-spy-counter-spy movie starring ol' big lips
herself. Take that with a grain of Salt (pun intended). Since the movie had
been shot with three different endings (or two different endings and a
directors cut but whatever), the DVD was released with those three
versions. As a side note, there were differences in the movie besides the
endings, too. If you consider what I wrote about having more data on disk
than it can apparently hold you'll come to the understanding that in order
to NOT have to encode three separate video/audio/subtitle tracks that
wouldn't fit on the DVD anyway without seriously compressing them, the
solution was to only multi-angle the differences. The bulk of the movie
used common data where applicable but the endings were on different
"angles".
I have seen this type of multi-angle referenced as interleaved" or
"interlaced". Do not confuse that with video frame interlacing where odd
and even fields alternate in a video to make a single frame. What seems to
happen (and I am not all that well acquainted with this technique because
it hasn't cropped up often) is as the movie/video is playing there is a
seamless jump in and out of the movie to different multi-angle data sectors
depending on what the language flag is set to. In simple terms... if the
language is English, play these sectors during this time period instead of
those, if it's French then play these sectors during this time period
instead of those.
I'll try an ASCII example but it may fail :)

Once again we fake the DVD into thinking there are multiple movies on the
disk when if fact there is one big bulk movie and separate multi-angles
played only as needed. Remember now, this is just how the video is handled.
The audio would always be heard in the alternate language.
One thing that tipped me off that something was amiss on the house-floating
movie was that I was seeing streams in .vobs with different video frame
rates... some "scenes" were NTSC standards and some weren't. Huh? A region
1 disk with video that wasn't NTSC? Ok maybe I can see that considering
most DVD player and DVD software will switch into a different frame rate,
sometimes even disregarding the DVD standards (such as MP3 audio streams on
a DVD on Region 1). But the thing was, the movie seemed to be interlaced
with different frame rates not unlike some telecined video.
So bottomline... if this is what you need for info, cool. If not then I
don't understand what you want to know. I did look at your posted picture
Angle1Angle2.jpg and it's quite obvious there's two angles there. So I
assume you didn't know this was possible?!? Some (most?) mpeg players have
an option to turn on and off or switch between the various video, audio and
subtitles. I know VLC does. Maybe you should become more acquainted with
how different streams types are embedded into a .vob It's quite an amazing
piece of technology if you like that low-level of understanding.
p.s. there are ways to get just the angle you want, but as i have stated, I
can't suggest how with Windows. I can suggest you visit:
www.videohelp.com/
That site has been a boon to my understanding of DVD structure, MPEG video,
transcoding, DVD/video software and techniques. There will be tutorials
there to help you get just the streams you want and leave the rest behind.
(This just isn't the best place for step-by-step tutorials... shrugg!)
This site is pretty good, too.
