In conjunction with the Atomos Ninja V+ recorder, the Canon R5 can now record 8K ProRes RAW externally - the announced AtomOS update 10.68 is now available. Supported frame rates for 8K recording are 23.98p, 24p, 25p and 29.97p. A 5K crop can also be shot in ProRes RAW, at up to 59.94p. Again, the Canon R5 must be running the recently released www.canon.de/support/consumer_products/products/cameras/digital_slr/eos-r5.html?type=firmware /firmware 1.4.0) for the appropriate output to be enabled.
§pic1§:Canon R5 with Atomos Ninja V+
With the update, the "normal" Ninja V (without +) is also able to record RAW with the Canon R5, but only the cropped 5K signal and with max. 30p.
According to Atomos, to prevent the R5 from overheating and interrupting recording even when recording RAW externally, the "Standby: Low res." option should be enabled on the camera; also, the "Auto Power off" power option should be disabled. If the recording is started via the Ninja V+ Recorder and not at the camera, the time limit of 29:59min should also be omitted.
Whether this way an unlimed 8K RAW recording is actually possible without the previous heat problems with the R5 will be exciting to see. Atomos explicitly points out that the recorder also gets very hot, so caution is advised when changing battery or storage media.
The following list in the release notes for the AtomOS 10.68 update lists the relationship between memory requirements and runtime. Atomos also notes in the fine print that the specifications for "continuous recording" only apply to a recording at 23°C and after a "cold start".
