I can’t help it to say that such a project with this number of files and the mentioned length
is bound to produce long safeing times and all sorts of other problems.
Why don’t you split it in reels and put them together in the end?
The extra work should be compensated with the shorter safeing times…
I mean, there is a certain natural limit to what a DAW can handle, these days, before it gives in.
In fact, I find it amazing that it only needs 15 minutes… and obviously produces no errors during safeing.
For me that project would be much to dangerous and to cumbersome to work with, as it is now.
