Trying to see if I can solve this:
I have three simultaneous 60 fps videos that are being locked to SMPTE timecode coming from Ableton via audio cable. Everything is coming in fine (I can see that resolume is receiving SMPTE track) but when the SMPTE lock is enabled, the video does not appear to be 60 fps, it appears to be jittery/slower. My computer is handling it fine, the FPS readout stays between 59-60ish, and if I set one of the three clips to sync to the "timeline" rather than "SMPTE" that clip plays back at the distinguishable 60fps and the other clips look slower (looks even slower than 24-30 fps to my eye).
I am curious about the mechanics of the SMPTE sync. Is it possible that only half of the frames in my 60fps video is being played back because the timecode track is 29.97fps? Or maybe, does the SMPTE sync require more computer power and my computer just can't handle it? The latter explanation would surprise me because if 1 of the three clips is not synced to SMPTE it plays back smooth but the two synced clips play back jittery.
Here is a dropbox link to a screen record, the left performer is NOT synced to SMPTE and the right performer IS:
