Hi all,
In my (holiday-video) DVDs, I'd like to use "theme"-based clips, that allow me to show specific chapters spread over different titles and VTS that match a given theme as a seperate clip. It's a bit complicated to explain; it could for example mean that I'd like to include a menu entry "Uluru" that shows the chapter about Ayers Rock of one video clip I made 5 years ago, followed by another chapter appearing in a different clip I made last year. Both these original movies are on the DVD as well. I know I could just copy these sequences, but it would be nice to use seamless branching. Unfortunately Scenarist still doesn't support this.
I tried to simulate this using GPRMs. It is basically working, but I'm wondering if there's an easier way (I'm not very familiar with GPRM-scripting) - maybe there's a HowTo for this? What I basically did was to add a dummy PGC in VMG (called "uluru") and using GPRM2 as counter for the sequences. The dummy sequence has just entry commands like (I enter them by mind now, so sorry if they are not syntactically correct and maybe I'm missing something... it didn't show to be as easy as expected :-)
"GPRM2 = GPRM2+1"
"GPRM14 = 1"
"(if GPRM2 == GPRM14) -> jump to title y1"
"GPRM14 = 2"
"(if GPRM2 == GPRM14) -> jump to title y2"
"..."
And in the corresponding titles I used the Pre-commands
"GPRM15 = 0"
"GPRM14 = 1"
"(if GPRM2 == GPRM14) -> jump to cell x1"
"GPRM14 = 2"
"..."
the cell command (there's only one possible as fas as I know) I activated for the corresponding cell(s) is:
"(if GPRM2 != GPRM15) -> jump to dummy PGC in VGM
This is a very tedious process so I'm wondering if there's an easier way to do that? Also, is there any way in Scenarist to enter these scripts more efficiently? Th clicking-procedure is EXTREMELY time consuming. I'd much prefer to enter them in a text editor and import them. Maybe there are external tools to do this?
Last but not least, I discovered my software player (Ciyberlinks PowerDVD) doesn't seem to implement the GPRMs correctly... the branching back to the dummy PGC is never done. It works on standalone players though. Is this a known bug in PowerDVD, or do I have to expect such behaviour in standalones as well?
Thanks for any help, Andy
