The EOS C400 camera records in 6K full frame up to 60p in 12-bit Cinema RAW Light. By changing the sensor mode, the camera can record 4K RAW up to 120fps and 2K RAW up to 180fps. This is all recorded in Canon’s latest iteration of Cinema RAW Light, which provides three different recording modes to choose from depending on your file size preference and workflow.

Other recording options include the Canon-developed, industry standard XF-AVC codec which can be recorded in 10-bit 4:2:2 with oversampling from the 6K sensor, helping to create rich detail and smooth imagery, at frame rates up to 120P, without the need for cropping the image from the sensor. Canon is also introducing two new recording codecs into the EOS C400 camera, XF-AVC S and XF-HEVC S. These formats feature an easy-to-manage naming system and folder structure, while recording in the familiar MP4 format and preserving metadata.

All of these options are recorded to the camera’s CFexpress slot with sub-recording and proxy options available to the SD Card slot, which allows for simultaneous recording even when shooting RAW.

 

 

It will be interesting if anyone makes a housing for it.  I don't think the C70 housings have been a real winner (I notice it is no longer on the Nauticam website) even though the footage from them is remarkable. 

 

Now that Nikon owns Red, things may shift around in the Cine market and this may play a role in it.
