I work for a network cutting promos. Using the Kona i/o to a digi deck. I have never had it slip a frame./knock on wood/ I have done inserts less than 15 frames and not a glitch. Take the plunge you won’t regret it. I have used them all *edit, avid,m100, liquid, and all the ones that didn’t last that long……. I was skeptical when put in front of the fcp but now…. I have seen the light.
