I have a problem that after export there are parts of the video that get lags.
For example, in the video below you can find it between 22:15 and 22:20 (and a few more places).
Recordings were made with an iPhone SE (30 fps) and a Sjcam SJ4000 (30 fps) camera in FullHD.
The pictures show the settings I used.
Can anyone help me out what the problem is?
