Thank you guys for all you input, found a solution.
So here was the problem. The footage I was working with was converted using toast and even though it had the same codec, ratio and frame rate it wasn’t enough.
If you want multicam you have log and capture your footage not convert it somewhere else. The reason I was converting somewhere else was because I didn’t have the AVCHD data on my Cannon card only the .MTS files that were saved to the desktop, this was causing the problem.
Thanks again.
