The Lumix GH4 is Panasonic's new flagship mirrorless camera, and the first of its kind to offer 4k video recording. Announced in February 2014, the GH4 is numerically the successor the GH3, but that model will remain on sale for those who are satisfied to shoot Full HD / 1080p. The new GH4 comes-in at a higher level to satisfy video professionals who want to film in 4k using a relatively affordable interchangeable lens camera. What can the GH4 do for you?

For all the combinations of video frame rates, bit rates, audio formats, and file formats this camera is capable of shooting, you'll have to consult Panasonic's site: I think there are 36, not including the options for new variable-frame-rate (0.25x to 4x) HD video. It's the first prosumer model to offer Cinema 4K (C4K, 4,096x2,160) in addition to Quad HD 4K (QHD, 3,840x2,160), and notably it supports potentially extra-high-quality HD, meaning 4:2:2 10-bit output with a 200Mbps bit rate at all the major frame rates. So, you can get 4K and 1080P footage easily.
