Bug Report Higher FPS MP4 Recording Than Desired

I hope this hasn't been posted before, but I've been using OBS for a lot of offline recording of speedrun segments, because of the ease of having an overlay and timer, and audio/commentary being blended together without editing.

I set my recording to 1280x720 .mp4 w/ no downscaling at 60fps. Encoding rate/buffersize is 10000kb/s, CPU is preset to superfast. The result video is 64fps. It plays back in sync in VLC player, but the audio will separate from the video if I throw it into a Premiere timeline for snipping. A product of Premiere only accepting a few framerates I suppose. What I end up having to do is running the resulting .mp4 in VLC, and using FRAPS to capture that. It's a bummer.

I tried using the Video/Audio Sync Fix, but that really doesn't do anything. As I said, the video works fine in VLC, I just think the higher than expected FPS is messing with it in any editor. Seems that the audio runs slower in the editor, as frame by frame the video and the timer on the video stay in tune with the timer on the screen.

x264 is variable frame rate so linear editors that expect CFR can be messed up. What sources are you using? OBS should generally try to maintain a constant frame rate unless one of your sources is lagging or there are other timing issues arising from somewhere. What CPU do you have and are you overclocking or messing with frequencies in any way?

I'm running Intel Core i5-2400 @ 3.1ghz, I don't overclock anything. Thought it fixed itself when I switched to 30fps, but I was wrong. Just takes longer to notice the desync.
