I live in the UK and we use the 50Hz tv system, this is 50i HDTV. However, I plan to shoot my vacation video in Europe later this year by using three different cameras, an action cam, my Galaxy S8 phone camera and my Panasonic FZ2000 (FZ2500 in US) as my main camera. The intention is to later edit the footage together and burn to blu-ray My question is, which frame rate should I shoot in for UK viewing compatibility? My Action cam and Phone camera only shoot at 30fps, yet the FZ2000 shoots at 25 or 29.97fps so will 29.97fps mix with 30fps without frame dropping if mastered as one or the other format? I know 25fps and 30fps drop frames when mixed and mastered but would i be wiser to shoot at 25fps instead of 29.97 on the FZ2000 being that i'm in Europe, even though i'm shooting in 30fps on my phone and action cam? Im talking about shooting 4k video too so 50 or 60fps are not an option with my cameras in 4k mode.
