Start with the part of your video workflow that needs fixing. The Canon EOS R6 V gives you selectable cooling to plan around during a shoot. The Nikon ZR offers an R3D NE and float-audio path that may suit the work you do afterward. Both record RAW internally, so wanting RAW alone does not settle the choice. Your existing lenses, sound setup, and editing software can matter more than either headline feature.
Plan the Canon around the actual take
The R6 V has Auto, On, and Off fan settings. That control is useful if you need to manage cooling deliberately, but it comes with a sound and power tradeoff: higher fan speeds can put more mechanical noise into recordings, and Medium or High shortens battery life. Leave the intake and exhaust clear. An external microphone placed farther from the fan may reduce pickup; check that placement in the scene you intend to record. Auto can keep the fan running in a hot environment, so choosing Auto is not a promise of a silent take.
Check the power setup before counting on those controls. LP-E6P batteries and the DR-E6P support full operation; older LP-E6NH and LP-E6N batteries restrict operation, including making Cooling fan settings unavailable. LP-E6 and DR-E6 are incompatible. The PD-E2 USB power supply requires a battery in the camera, and a depleted battery charges instead of supplying the camera. Even with external power, the battery reserve can decline. A supported supply and a charged battery belong in the recording plan.
Active cooling still has a limit. The R6 V can issue temperature warnings and shut down, and it may overheat again after cooling and restarting. The ZR uses passive heat dissipation without a fan, but it also has temperature warnings and a shutdown countdown. Its higher temperature cutoff setting does not guarantee unlimited recording. For either camera, rehearse a representative take with the intended settings, power, microphone, and environment before committing to a job that depends on uninterrupted recording.
Make the Nikon files earn their place in your edit
The ZR's R3D NE uses a RED Log3G10 and REDWideGamutRGB workflow. It is a distinct recording format; renaming an N-RAW file does not turn it into R3D NE. Check support for R3D NE specifically in your installed application version, then try a representative file through ingest, grading, and export. General RED file support is not enough to establish that this path will work for you. The Canon's RAW files also need compatible software.
The ZR can record 32-bit float audio through its built-in microphone or 3.5mm input. A compatible ME-D10 can provide float audio through the digital accessory shoe, but other shoe accessories should not be assumed to support it. Enable float recording and choose a supported RAW or MOV mode; MP4 records AAC instead. An external microphone or line input takes priority over the shoe, so confirm which input is actually being recorded.
With compatible post software, float audio gives you room to adjust levels afterward. It cannot undo distortion from the microphone or input device, or remove noise already captured from the equipment or scene. Unsupported apps can have playback or level problems. Audio input sensitivity AUTO is unavailable in float recording, and sensitivity cannot be changed during recording. Position and monitor the microphone, then verify the audio in the software used for delivery. Buy for a working capture-to-edit path, not the expectation that float will rescue any recording.
Price the kit you would actually use
Canon RF and Nikon Z are different native lens systems. Account for the lenses you own, any specific lens or adapter compatibility, microphones, supported power, and cards and readers suitable for the chosen recording mode. RAW can also bring storage and editing requirements; do not assume that every existing card or computer workflow is sufficient.
Matching, currently purchasable US complete-kit totals remain unconfirmed. A body listing leaves out these other costs, so it cannot establish a price premium or a value winner. Get a current quote for the setup that will do your work before deciding to switch.
The R6 V is a conditional fit when selectable cooling addresses your recording needs and you can support it with power and a workable sound setup. The ZR is a conditional fit when R3D NE and float audio serve an editing workflow you have checked. Those capabilities do not establish a winner for recording duration, battery life, image quality, sound quality, or editing speed without matched tests. If your present camera, audio recorder, and editing path already deliver, keeping them is a sound option. Wait to switch if the codec, input chain, power, or complete-kit cost is still unresolved.
