GH4 toggle between 4K and 1080 60 for slomo

[John Snelson]

I have previously been shooting pretty much everything at C4K witht he system frequency on 24 (you have to for C4K). I shoot football so I will need to shoot slomo a lot too.

 

If I understand correctly, the best way to shoot 60fps slomo is recording the FHD 200M at 1080p60 with the system frequency on 59.94 rather than leaving the system freq on 24 and using variable frame rate.. Problem is, you dont want to be changing the system frequency during a game. Is the best way just to leave system freq on 59.94 and use UHD 4K rather than C4K? Or is there a way to quickly toggle between C4K and 1080p60 at its highest quality
