So I thought I'd try using the profile analyzer on the produce tab, and it recomends MP4 > 3840x2160 > at 10000fps lol

I used MediaInfo and found the original clip (test.mp4) you shared is encoded in 10K fps (it is in dynamic fps and the maximum frame rate is 10K).

As what you said "New phone, new problem", did your new phone really record the 4k 60p video properly?

If a video contains 10k frames a second and the resolution is in 4K, I'm not surprised it will be laggy and uneditable in a video editor. Even though it can be edited in other video editors, it cannot explain and proof that your source video file is a fine one.

Have you ever contacted your phone vendor to clarify this technical issue?
It does not encode video properly with correct video metadata.

Thanks for looking into it, Yeah its really odd. But the video stays at 59-60fps when playing never goes up lol so thats weird.

Yeah deffiantly a weird encoding issue with the phone, but PowerDirector is the only video editor that doesnt support it correctly despite the weirdness of the file.

Phone venders will never help with this, they'll blame the computer, person, user error or want to RMA the phone lol. When its clearly a software issue on there side. Its the OnePlus 8.

Every video clip that comes from this phone, I have to render the clip unedited first in powerdirector, and then edit the rendered clip as a workaround.

Somehow I missed the stats on the original clip, but now that we all know it has a max framerate of 10kfps, that at least explains why PD's shadow files ended up with that framerate.

I just ran the clip through Virtual Dub2 and re-encoded the clip at a constant 60fps. I don't see any issues when working with this clip in PD, and I imagine it'll work fine on your system as well



You may want to take a look at the video settings on the new phone to see if changing any of them can avoid recording with spurious fps.

No settings to change for frame rate except for 240fps slow motion. It also happens in 3rd party camera apps as well. Really strange software issue.

4K at 10kfps would be nice at slow motion for a $350 phone haha.
