Encoding Samsung 30.031 / 30.011 fps files

I have some videos shot on a Samsung Galaxy S10+ phone that I need to edit, and I really don't know what to do with the frame-rate. MediaInfo reads it as 30.031 fps, Premiere Pro reads is as 30.011 fps, both being non-standard. I normally work with 25 fps video, and export from Premiere in DNX HQ mxf files which I then transcode with HandBrake to H.264 or H.265 (because HB has the essential constant quality option, which is missing from such an "advanced" video editing suite as Adobe CC).

Now DNX HQ doesn't have even the option for 30 fps, the closest would be 29.97 fps. Since this means changing video frame-rate anyway, should I stick with 29.97, or should I encode 25 fps, as with all my other videos (which are shot in 25 fps); which of these two options will give the best result?

Please keep your truisms for yourself, I am here to find answers for my questions and not to read platitudes from "pro"s.

The fact that Premiere is missing basic features that can be found in free "amateur" software makes your "pro" sound like you're advertising crap for gold.

The cell phone video is truly variable and that's why you get various frame rates.

I would think you'd get the best results my exporting to a constant 25fps in an intermediate codec.

That I find a big problem mixing framerates (using so-called pal and ntsc fps). I avoid 24/30/60 at all times.

(if the file is cbr I transcode in Ae)

Transcode file directly in Handbrake and see if you can get a good result by setting the framerate to 25.

Or use Ae to get 25 fps from the CFR file.

Trial and error.

The thing is, I need to edit the file, I can't just transcode it in HandBrake. Or do you mean to transcode it and then edit? Wouldn't that just be an extra transcoding H.264 to H.264, potentially reducing the video quality?

On the other hand, I noticed that the video file actually has variable frame rate, which makes things even weirder. Can Premiere Pro export with variable frame rate, will it keep the variable frame rate if I export in with the same codec (H.264) and the "Match Frame Rate" checkbox ticked?

Yes, HB does a descent good job

Can Premiere Pro export with variable frame rate,

It will export to constant but in most cases will take on the wrong framerate and still be out of sync.

Premiere suppose to handle vfr but I dont think it does a good job.
