Shoot in 4K and a Variety of Frames Rates with Panasonic DMC-GH4 | Prolost
"The real story here is the GH4’s video recording capabilities, which include 4K and 1080p, with support for the IPB and ALL-Intra codecs. Shooting aids include focus peaking, zebra pattern, luminance level adjustment, and cinema gamma presets. An optional ‘interface unit’ adds five SDI and two XLR terminals, and permits 10-bit 4:2:2 output with time code."
