P3P is what I would recommend. I shoot in 4K and downscale to 1080p. Looks so much better than shooting plain 1080p due to a thing called chroma sub-sampling.
Worth it for this alone. And you get a faster charger
You will get more chroma information shooting in 4k but you also get more compressing due to the 60mbs vs 40mbs in 1080p so shooting in HD will have less compression artifacts.
