I'm trying to edit a 500 gig video file (I think it is avid's dnxhd codec) with a macbook pro i7 with 16 ram.
I have a generic usb 3 external drive (I'm guessing this is the problem)
my main problem other than the fact that it works slow, is that the sound buffers very very slowly if at all.
is a good hard drive going to solve that problem or I need a more serious editing system for this?
Is that 500gig file one single video file? That sounds extraordinarily large for a single clip.
Do you know what setting the DNxHD is?
Because DNxHD 120, 23.98fps, 1920x1080, you would be looking at about 10 hours to fill 500gb! (I'm getting this figure from the Formats app, by the way, so don't know how accurate it is: http://grayhourmedia.com/formats/)
If that's the case, I would definitely think about two things:
1. Breaking the clip down into smaller chunks (maybe an hour or so each)
2. Making lower res/bitrate proxy files to work from
