Hi. No its not a problem 29fps. Just changed settings on the phone to record in 60fps and it done the same. Previously i recorded in FHD 1920×1080 now i selected option on the phone FHD 1920×1080 (60fps)
Other options
UHD 3840×2160
QHD 2560×1440
1:1 1440×1440
HD 1280×720 >> sony vegas does it same in this quality also ?
VGA 640×480
maybe get some codecs? only windows media player worked perfectly at the start and then lagged with pixels, MPC player doesnt perform well also nor does VLC. Laptop is high spec with good graphics card so it shouldnt be a problem with hardware.
