When recording in-camera, 4K video has 4:2:2 sampling and 8-bit color depth, while Full HD 1080p footage has 4:2:0 sampling.
Uncompressed Full HD 1080p video can also be saved via HDMI to an optional external recorder with 4:2:2 color sampling.
Audio can be recorded using the on-board stereo microphone or an optional external mic can also be used via the 3.5mm mic jack.
The Canon N3 remote port has been relocated to the front of the camera body and they have added both GPS and Wi-Fi with NFC to make this model a connected camera.
In line with previous members of the main 5D series, the Mark IV attempts to balance high resolution with low-light performance with a newly developed 30.4MP full-frame CMOS sensor.
Also, this works well with the touchscreen functions, allowing shooters to just tap to adjust focus.
Designed for both professional stills shooting and video recording, the 5D Mark IV supports DCI 4K (4096 x 2160) resolution recording at up to 30 fps at 500 Mbps, along with Full HD 1080p shooting at 60 fps and HD 720p at 120 fps for slow motion playback.
