Ok, I'm trying to edit some HD videos shot on my Nikon DSLR, and they're pretty sizable H.264 .MOV files. In the past I've just converted them down to 720p AVI's, but this time I would really like to make a high-quality 1080p movie. The problem is that these large videos slow down Premiere quite a bit, making it really difficult to edit them. The audio plays just fine in Premiere, but the videos are choppy and slow, making it impossible to accurately cut between shots, etc.
So I had this idea: Why not make smaller, poorer-quality versions of all my clips and edit them: make all the cuts etc. that I need, and then when the movie is exactly how I want it, just replace these crumby substitute files with their respective real-deal 1080p .MOV counterparts.
My question is: IS there a way to do this?
Would it basically just involve making a folder full of smaller, poorer-quality MOV files with the same names, loading them all into Premiere, and then later replacing them and tricking the program? Would that work, or would Premiere realize that these are NOT the same files and freak out?
Thanks in advance for any assistance you can offer!
