We "helpers" here are peers. Other users. Ann, in particular, is one of the most experienced in a wide range of workflows helping here. You want an expert? With her, you got one.
But as she said, we're not clairvoyant. Troubleshooting always requires information as to the hardware, media, and effects involved. As the vast majority of issues only exist under certain conditions.
Variable frame rate media is a freaking hassle ... you do understand the audio and video are recorded differently, right? The audio is recorded constant, the video varies. I can set my Samsung phone to 30fps, and I'll get a file that constantly varies from say 27.66fps to 31.1fps.
Phones have specific hardware to handle this. Video players don't have to mesh an audio stream with multiple video streams like an NLE, so they may struggle a bit on a computer but get by.
The NLE has to mesh perfectly frames that aren't there with stuff that is, on the fly. That is an enormously difficult process. And is why NLEs really struggle with VFR media. I'm totally a practical guy. I go with what works.
VFR, like most H.264/5, are great capture formats for devices with the specific hardware chips that do the encode. They're lousy editing formats because of their structure however.
And as far as converting VFR, you should also look at ShutterEncoder. It has a more "modern" UI than Handbrake or ffmpeg.
