Hey guys, I'm looking into cutting together a montage using footage from feature length movies. The end result will be a few minutes comprised of fairly short clips, but the source material is many extremely long clips (90-120 minutes.) I'm wondering if you guys have any guidance about how best to deal with large files. I haven't fully crossed over to FCP X, but I'm enticed by the organizational tools and the freedom from rendering (the source files are different codecs, sizes, etc. ) Do you think I should go through each 1-2 hour clip and remove all the parts I won't need, leaving me with smaller more manageable file sizes? Or would it be easier to import everything and sort and organize with FCPX keywords and favorites. I'm hesitant about the latter option because I'm worried I'll be bogged down. The two machines I'll have at my disposal are: Mac Pro (Tower) Processor: 2 X 2.8 Ghz Quad Core Intel Xeon Memory: 10 GB 800 MHZ Laptop: Processor: 2.26 Ghz intel core 2 Duo Memory: 4GB 1067 Mhz DDR3 Any workflow tips or guidance would be very very much appreciated. Additionally - many of the clips are h264 and avi - I experimented with exporting to Apple Pro Res, but the files got so huge I couldn't work them. With FCP X is it worth the while to convert to a certain codec? I know H264 is an output codec but I have a lot of footage to cull through, so I'm trying to make sure files sizes not get out of control... Thank you very much!
