What's the accepted thing to do with a profile when a DVD is produced on a DVD 10 (double sided, single layer) with each side containing exactly the same content but with different aspect ratios (eg 2.35:1 on one side and 1:1.33 pan and scan on the other)? I know you can add different disc IDs, but the video info has to either be one or the other, not both...

If a movie is on both sides of a disc in Widescreen and Pan & Scan or Full Frame versions, identify this by entering the Side A description as "Main Feature (Widescreen)" and the Side B description as "Main Feature (Pan & Scan)" or "Main Feature (Full Frame)", or the reverse if that is the order on the disc sides.


And in the formats in the profile, simply select all that apply and put 2.35:1 in the ratio.  There is no need to specify both ratios because P&S is always 1.33:1

Nope, PAN&Scan can also be 1.85:1 or anything else.
The german "Crying Freeman" DVD was cropped from 2.40:1 to 1.85:1.

Cropping is NOT the same thing as Pan & Scan.

Actually, there's nothing to say a "pan and scanned" film has to be 4:3, so in theory that German DVD can be classed as a "pan & scan" although at the moment the program assumes P&S is 4:3 -  we'd need clarification and/or discussion to see whether we'd want that changed.

To answer the original poster though, the two-sided disc I have has both "pan & scan" and "widescreen" boxes ticked, and the widescreen aspect ratio filled in. That seems to display the required info in the profile.

I would disagree; if there is a smaller frame 'panned' within the larger, correct, frame it is essentially a widescreen P&S but still P&S.

Never gave much thought to this, but I do agree with you on that. Do you enter them as such? IMHO, the problem is DVD Profiler doesn't handle that very well: it does let you enter both a widescreen aspect ratio and check the 'Pan& Scan' checkbox, but as a result the Audio/Video panel will show 1.33:1 Pan & Scan. That I don't like, so until now I've always entered these as widescreen, even though they're cropped. I'm also slightly worried that we'd have to deal with over-enthusiastic users saying: "The OAR for this movie was 1.85:1 and it's on the disc in 1.78:1 - that's P&S!"...

Yes... to be honest I suspect leaving it alone for now makes sense (until a proper set of Rules are sorted out and, if required, a modification to the software is provided). My comment was more along the lines of "Well technically I agree, but I confess I don't have the answers to the problems if we implement it this way right now"

Cropping is NOT the same thing as Pan & Scan.

The frame was manipulated in a way, that the action is always in the frame. Isn't that the definition of pan&scan?
Again, it doesn't matter what aspect ratio the result is, as long as the picture was zoomed.

Sorry, but P&S involves moving the 4:3 point of reference back and forth within the widescreen format so that the focus of the scene remains on whatever the editor decides it to be.

Cropping, or converting from one widescreen format to another involves changing the placement of the upper and lower edges, and then adjusting the vertical edges in or out to keep images proportional.  There is NO shift of point of view at all.  Some data may be lost at the edges depending on which way the conversion is going, but that isn't the same thing at all as P&S.

One of the problems often seen in conversions is that the horizontal edges grow and you can see the boom mike peeking into the top of the frame.  That is why you seldom see conversions being done these days.

That's how I've always understood P&S, hence my comment that is always 4:3.  In any case that doesn't matter much for the purpose of DVD Profiler.  I believe I was correct anyway in recommending that both WS and P&S boxes are ticked using the aspect ratio of the widescreen version.

That's not quite true. Although P&S is almost exclusively 4:3, it still can be used to convert from one widescreen ratio to another. I know that I've used it at least once where I was converting from 2.35:1 to 16:9 and I had two people on either side of the screen, so had to pan from one head to another to make sure both were seen.
Just because the image loss is not as much as the conversion to 4:3 doesn't mean we don't have to shift the point of view to keep certain things in shot.

Edit: but Touti's right, for the purpose of Profiler, it's best to assume that P&S means 4:3.

Please explain to me, why doing the same thing with the result of a 1.78:1 picture is not Pan&Scan. Until now, you failed.
For example:
A few years ago, the german television programme Pro7 Pan&Scanned Once Upon a Time in the West to 1,78:1. In all standoff scenes, the frame moves from the left to the right. This camera movement is of course not part of the original version, because both persons fit in the 2.40:1 frame.

The very definition of Pan&Scan.
