Thoughts on this noise from new clutch?

Sounds to me like it up under the dash. Can you feel any of it in you foot? Like when it clicks you get a notched or stopped feeling? It sounds very consistent too. Is the mater cylinder or its mount tight, if it s a bit loose it rocking could make that noise going off and on the pedal.
I don't feel any hesitation in the pedal. Also, the sound isn't always there, it comes and goes. I can wiggle the pedal a little bit from side to side so maybe something is binding a bit. I sent the video to the tech guys at Silver Sport Transmission (they sold me the clutch package) and got a nice reply. The tech thinks it could be fire wall flex. I'll take a look at it this weekend and see if I can see any flexing.
