I am just just about done editing a full length feature film that was originally over two hours long and re-edited down to one hour and forty eight minutes. Here’s what I learned from my experience. If it’s along form piece, you should talk to the person who will be doing the sound design (or audio mix) on the piece to see if their equipment can handle the entire timeline audio export or if their system can handle only 10-15 minute segments of a timeline at a time and factor that into your exports. I was also told to put 2-pops at the beginning and end of my timeline so when the audio mix is laid back to the timeline, we would have a simple way to make sure that everything synced up as it should. Make sure that when you export you audio as an OMF file that you have adequate handles on your files. I’m sure that if you glean a bit from me and the others in the post you should stay out of trouble.
BTW, you asked about project size. right now we’re at 1.8 TB and operating off an XSAN. That number should get bigger after we send it to Color and back.
Happy Editing and I hope this helps.
