I heard it's possible to do by copying time stamps. Or is there any other way?
The problem has got to do with Nvidia Shadowplay and Adobe Premiere.
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays!

If there is only minor jitter in the timecodes, you can treat it as CFR and you can use mp4fpsmod to override/set the timecodes without re-encoding
But if it's really variable (in terms of lots of fps fluctuations), you will go out of sync. In that case smart thing to do would be re-encode with CFR. -
it basically fluctuates between 59 and 61.
Can you refer me to how do that with mp4fpsmod? -

whats wrong with people and always wanting the quick way out - encode and enjoy

If you don't remux with timecodes, it should be CFR . Timecodes control the display time per frame (speedup, slowdown in sections)
An elementary video stream has no framerate (except sometimes a declared framerate in the header, but it's only 1 framerate, there is no variability)
Sometimes the problem is the muxer. Certain timebases used by the muxer cannot reflect certain framerates as integers so you get rounding up and down, or jitter. Other times there is a mismatch between the timebase in the container vs. bitstream declared timebase and that can cause interpretation as VFR.
Eitherway, for a MP4 stream , mp4fpsmod will work, but demuxing/remuxing without timecodes should work as well
