View Full Version : Navigation timer problems

Hi all:

A friend of mine is working with Scenarist and has found a puzzling problem. He is creating a photo gallery, with Prev./Next buttons for navigation, and the client wants the DVD to jump automatically to the next picture after X seconds, if the user hasn't pressed any button. He is doing this with a navigation timer, and during the simulation everything is fine, but when compiling the DVD, Scenarist spits out several errors:

No.1 pre-command error at PGC"Foto_03-t-pgc", "VTS_2" (SetNVTMR destination is No.17 PGC, but it does not exist in this Title)

...Where "Foto_03-t-pgc" is the name of the PGC that contains the photo, and "Nš17 PGC" is the PGC of the next picture (the one that it should be jumping to).

It gives this error for every photo that has a navigation timer set up. Obviously, it's saying that it can't find the PGC that it should be jumping to next... except that the PGCs *do* exist. My friend picks them up by going to the Simulation Window, setting up the navigation timer in the "Pre" commands and choosing the proper PGC in the menu that appears. And when playing the simulation, we pay attention to SRPM 6 (which has the number of the PGC that is currently playing) and the numbers are correct; in other words, when the simulation jumps automatically to the next photo, the PGC number that appears is the one that supposedly doesn't exist.

My friend has tried everything, including deleting all the menus and assets and importing them again, but nothing seems to work. Is anyone else familiar with this bug?

(Also: we know we could make the photo gallery using a Slideshow, but the client doesn't want it: they like having the Prev/Next buttons onscreen being activated when the user clicks, and don't like having to use the Prev/Next Chapter buttons in the remote to navigate).

IMHO the easiest way to go in this situation is to create one single PGC with all the stills as one second slideshows: add highlight to them, then build your PGC by cells or chapters, as you wish (cells if you dont want the user to navigate with prev/next), then set the "Cell Still Time" for each cell (in seconds, 255 = infinite). This process is also easy to automate with a simple script.

you can also do the compile w/out the commands and then add them in with pgcedit or ifoedit.

as long as they are in the title domain and in the same title it shouldnt be an issue. in quick testing i couldnt duplicate your issue

IMHO the easiest way to go in this situation is to create one single PGC with all the stills as one second slideshows:
PGC can have 99 programs maximum. So it will be necesary to put them in several PGCs and set PrevPGC/NextPGC to link this PGCs together (for Prev/Next button to work).

Actually you don't need Scenarist to do all this. Muxman (to encode images and to multiplex vob) and DvdReMake Pro (to insert navigation) will do job nicely. You can even make several slide shows (that reuse same video) with different playback speed and/or playback in random order.

Well, in our case the photo gallery only has 10 pictures, so that's not a problem (the 99 programs limit, I mean).

Anyway, we did a quick test with the solution DaRat proposed and it seems to work. What we have observed is basically that the picture stays onscreen for the duration of the slide show (1 sec.), and then it waits the time specified in "Cell Still Time" (10 sec. in oru case)... and *then* it jumps. That's correct, right?

That's right, it supposed to. :D Tough drop the stills as cells if you dont want to mess with eiether 99 the program limitation and/or setting the UOPs to prohibit prev/next buttons.
