Thanks fox_m; this is an IMAX film. We're trying to hold onto all the quality we can going through the pipeline. I know 4K ain't really IMAX, but my brother - who's done a score of IMAX with the big film camera - is sooooooo happy to be working with the little 4K cameras; and you know, looks pretty good on the big screen ... especially if the story is engaging enough to make you forget technology.
The FCPX solution actually did work - bopped all the RAW stills onto the 'project' timeline, control D to change duration, and changed the duration of all of them at the same time, thank you Ian;
NOTE: When changing the duration, one discovers you have to hit control D, then just start typing in the number you want - if you actually click the duration window, nothing happens, it pops you out of the function mode I think. Or something like that.
I did set up Motion ... which I will be using after today for some effects scenes ... but didn't have the courage at the moment to figure out where I need to set various and sundry things. Tomorrow for that. Meanwhile, FCPX.
Thanks guys... very much appreciated...
Ben
