I have a lot of comps in my project, and it's useful to see the thumbnails in the Project panel. The first frame of most of my comps is completely blank, so the default poster frame is useless.
Does anyone know of a script that will set the Poster Frame Time to, say halfway through the comp duration? For example, if I have a 10sec comp, the script will set the poster frame time to 5sec. This should give me a reasonable idea of what each comp is, without having to open it. So it would be great to be able to select a load of comps, then run the script to adjust all the comps' poster frame times.
