#5 Preview movies

[Magnus Nilsson]

What I found myself doing by hand when creating a bunch of DVDs was wading through thousands of jpeg-files, deleting and copying to make the
previews be exactly the way I wanted them.
In the first movie, I wanted the preview to be seconds 5-20, in the second movie, I wanted it to be 10-20, in the third, I wanted 100-115, a.s.o.

I realise I can get this by running the movie-title multiple times with one of the movies as argument each time and thus get the correct start of the jpegs in the movie-jpeg-directory, but it would kind of be neat if this could all be done in just one run. For example by including the start time in the .info-files, with for example and entry like "Preview-start:"

I also ran into trouble because I wanted previews of different lengths from the different movies. I solved this by copying the pictures for the shorter previews to make them all equally long. This too would be great to be able to include for example in the .info-file, like "Preview-stop: 14". The script would then compare the length of the preview with the length of the title-animation and if the preview is shorter copy it enough times to fill out the time. Thus, if the title animation (or sound) is 30 seconds long, a 10 second preview would run 3 times while a 5 second preview would run 6 times.
