Question / Help Constant framerate: not sure if working

Last night I recorded some 60 fps footage hoping to upload it to YouTube.

I noticed a frame skip from time to time and I suspect it's not holding up 60 fps. I don't think the cause is from my MPC-HC lagging or anything like that (although the video is 30,000kbps bitrate).

I checked the video specs and noticed the minimum framerate is 58.824 fps and the maximum framerate is 62.5. The only thing that turned out to be 60 fps was the total average. I already have CFR enabled in OBS but I don't know if it's working as intended. The video source, which is my capture card, is set to display my Xbox 360 in 59.94 fps. So I at least expect 59.94 fps and not 58.824 fps.

PS what x264 profile level should I use for 60 fps footage? High 4.1?

Could you post a log?

Sure but this a recent log of a 62 fps test to offset that small margin of hitching. Log is too long for the post I'll have to shorten it
