Exported playback glitch

I downloaded the first two, 1 was 720p and the other was 1080p. The only odd thing I could see was when I first put it into PP and I was just dragging the playhead over the footage, and I could swear I saw some green stuff, especially in the lower right area...but I couldn't find a frame to settle on to see it. Otherwise, I put it into a 1080p sequence and exported with match/high bit rate h.264 and it looks OK. I export 22mins. I couldn't find a glitch. I didn't convert to cfr, I just tried the clips as is. 

Are the glitches random or happening in the same spots each time you export?

^ this is the raw footage before the vfr to cfr conversation

Ok I can get you that, one minute 

I was hoping for one of the raw clips that cause the problem, rather than the final export.

wow it is still having the same issue, even after the VFR to CFR conversion on all 3 camera angles I have on this. Here is the Dropbox link to the whole video. It happens a couple times, one of them is minute 4:11. Anyone have anymore ideas

Do you have one of the clips that causes the glitch...

I didn't see the CFR in preferences, good item Neil, I've always used the Advanced setting.... as I'm usually just doing one or two...

That's in the Preferences/Settings window ... the little gear icon in the upper left corner. Rather well hidden ... 

I am in shutter encoder now, uploaded my files. I am not seeing any option to "set frame rate mode" as it looks in the screen shot you sent.
