Best long term format for futureproofing?
When can I delete an iMovie project I'm working on?
I'm wondering when I can feel safe enough to delete family iMovie Projects and Events? With software changing so fast, do I just need to keep them all in iMovie in case I need to Share them to some new technology? Today it's iTunes, but what format is next?
I'd LOVE to finish all my family iMovies and know they were safely exported to some format that was 'it', that would be flexible enough to be imported into whatever future software was used to keep them current. What's the best format for this, if there is such a thing?
Otherwise, do I have to just keep all my events and finished projects in iMovie in case I need to Share them to some new format that comes along?
