why need to render only overlapping video files?
on Apr 23, 2010 at 11:59:30 pm

For some reason, if I have 2 video tracks ontop of each other in the timeline, I need to render the files. I am editing a music video, so no audio is in the video tracks. my sequence and capture presets all match. It only needs to render when on is one V2, and one is on V3 and they over lap.

why is it only on overlapping files I need to render?

Because your hard drives are only supplying sufficient throughput for one video layer.

Clearly, you are most likely editing off of a single firewire drive, right?

Well, if you've ever wondered why most of the people who really do this type of work for a living all have eight-drive (or even larger) RAIDs, now you know.

I am editing from my internal hard drive... should I edit to another external, would I get better results?

Using the system drive for media is a totally no-no. If it is a separate internal sata then that should have enough speed but single drive systems are much more fragile than RAIDs with redundancy.

At the moment I have both an external fibre Channel RAID and an internal 3 drive RAID5 which can handle HD uncompressed easily.

Never edit from the system drive!

Think of it this way. Your system drive already has a lot do do, it is running the OS and applications. Making it also deal with active heavy video files at the same time is just giving it to much to do.
