The hottest debate in camera world is about two major stakeholders i.e. Canon & Nikon if which one is better while this may vary product to product while personal preference & brand loyalty plays a part to so today we turn the heat up & see if which shoots Better 4K & Slow Motion?

Let’s clear this at first that there isn’t a single winner both brands are reputable and make stellar video capable camera but approaches are different ,Canon focuses on filmic color science wide internal RAW/Log options (and a dedicated cine variant), and very approachable AF in video whereas Nikon pushes sensor read out speed ,high frame rate  & pro level sustained recording in flagship bodies.
To start with Canon’s recent full-frame models (and its cinema line) emphasize strong internal 4K options, oversampling modes, and accessible Log/RAW workflows. The EOS R5, for example, brought internal 8K RAW and full-frame 4K up to 120 fps plus Canon’s R5 C variant is explicitly a “cinema” model with active cooling and extensive RAW choices for long takes. These features mean Canon can produce very clean, color-rich 4K that’s friendly for grading and heavy post-production whereas Nikon’s Z-series (especially the Z9 and Z8) takes a different tack: powerful stacked sensors with super-fast readout, internal high-bitrate RAW options, and pro codecs that minimize rolling shutter and retain detail even at high frame rates. The Z9 and Z8 can handle 8K workflows and true 4K/120p with pro-level robustness delivered in camera bodies built for heavy professional use. That makes Nikon a very attractive option for filmmakers who want long takes, reliable high-fps performance, and minimal artifacts. 
The “Slow motion” capability is often the deciding factor for creators & why not as two things matter: maximum fps and whether those fps are available in the same quality (bit depth, chroma subsampling, RAW vs compressed) as your normal 4K.

·         Canon: Modern Canon bodies let you shoot very high frame rates in-camera (4K up to 120p on R5 family and the R5 C; many Canon hybrids also offer high-frame full HD slow motion). Canon’s cinema hybrid (R5 C) removes many recording limits and gives you Cinema RAW Light for heavy grading. That makes Canon great when you want slow motion with vivid color and grading headroom.

·         Nikon: The Z9/Z8 design lets Nikon offer sustained, high-quality 4K120 and 8K capture with fewer compromises. Because of the stacked sensor and processing, Nikon’s high-fps modes are not just “short burst” tricks — they’re built for pro workflows (and often include options for internal ProRes/RAW). If you need long slow-mo takes at the highest possible quality, Nikon’s flagship bodies are very strong.

Evidently the lower-tier or older models from either brand will often limit high-fps to cropped modes, lower bitrates, or to Full HD rather than 4K. Always check the exact model’s 4K/120 vs 4K/60 behavior before you buy.
This maybe a debate but Canon’s Dual Pixel AF historically has had the edge for reliable, smooth subject tracking in video considering it’s fast, predictable, and easy to use for solo shooters. That makes Canon dslr camera price in pakistan popular with run-and-gun creators, wedding shooters, and vloggers who depend on autofocus during complex moves.
Nikon has closed that gap aggressively with subject recognition and tracking updates in the Z9/Z8 line. For very high-speed capture (animals, sports) the Z9’s tracking and blackout-free EVF give it advantages and with pro rigs Nikon’s AF + high frame readout is extremely reliable, to sum it Canon feels friendlier for solo operators; Nikon is incredibly robust when paired with pro workflows and lenses.
This bring us to the two real-world headaches for video shooters are rolling shutter and thermal limits.

·         Rolling shutter: Fast sensor readouts (stacked sensors like Nikon’s) reduce rolling shutter skew. That’s why Nikon’s Z9/Z8 are frequently praised for clean motion without jello/warping artifacts during fast pans.

·         Overheating / recording time: Canon’s original R5 made headlines early on for thermal limits when pushing 8K or 4K/120 heavily — firmware updates helped, and Canon’s cinema R5 C addresses the problem with an active-cooling design and unlimited recording options in many modes. If you need to record long 4K/120 takes without a cage, fan or external recorder, consider a cinema-oriented body or Nikon’s pro bodies which are designed to sustain long sessions.

Having said If you intend heavy color grading, both companies offer Log/RAW toolsets ,Canon with Canon Log / Cinema RAW Light / ProRes options on certain models, Nikon with internal RAW (and ProRes in recent models) and strong N-Log options. Canon’s “film” color science often requires less grading to hit that cinematic look out of camera; Nikon’s RAW gives more latitude for extreme color work and retains detail at high frame rates. Choose based on whether you prefer pleasing out-of-camera color (Canon) or the maximum latitude of RAW and pro codecs.
To conclude this would advise if your primary question is “which shoots better 4K & slow motion?” Nikon’s top flagships (Z9/Z8) are built to deliver clean, long-duration high-fps capture with minimal artifacts, while Canon’s lineup (R5/R5 C and R6 II family) gives you filmic color, strong in-camera RAW/Log choices, and user-friendly AF. For solo content creators and those who want Canon’s color and workflow, Canon remains an excellent choice; for pro cinematographers who need sustained high-fps, minimal rolling shutter, and raw power, Nikon’s big bodies lead the pack.
