radnom timeline marker

Hi,

I'm new to expressions, and having searched a bit I can't find the answer to what I'm looking for, so I'm hoping someone may be able to help. There may be a better way to do what I'm trying to do, but I think there must be a suitable expression!

Without going into detail about what I'm trying to achieve (I'd be happy to if it helps) I winder if there is an expression that will allow me to tell the playhead to navigate to any goven point aling the timeline, at random.

For example, I place 64 shots sequentially along a timeline. they are of varying length. Can I add a marker or something at the beginning of each clip (if necesary) and then tell the playhead to go to shot 36, then shot 42, then shot 1, but for it to decide which point itself and randomly? SO that if this were to be duplicated, the results would not be the same, and different points on the timeline would be be selected and therefore different clips being played?

If it helps, the plan is to get a timeline with 64bsequential clips in it, add these 64 shots to a new comp in a grid so I have 64 clips playing at once, but thanks to the expression, hopefully none at the same time. Does this make sense?!

This is an unpaid collaboration, so I'm not trying to make a wad of cash on the back of some very clever advice, but I am trying to work in the most efficient way I can. To do this manually is scaring me!

Many thanks in advance,

Dave
