“Tri-sync is gonna last you longer than your $5000 G5 or $2K capture card”

Rule of thumb is if you are dealing with with progressive, flat frame rates (ie 60p and 24p) you will need it – especially if there is a cross conversion going on. For things like 59.94 and 29.97 based projects you can get away with your standard balck burst.
