Re: [Avid-L2] Mixed 3perf and 4perf in a project

hi Rainer,

I had a vague memory of the 4 perf going as far as 15, and 3 perf going as
far as 21.

I'm afraid I'm too tired to follow the later half of you post.

The best idea I have is to go through the project shot by shot, colour
coding rolls that I identify as 3perf one colour, and then 4 perf another.

I'm wondering if there is a more elegant and smarter way of doing this.

Thanks

Aidan
