The Vivo X300 Ultra promises top-tier video specs but trips on autofocus in fast motion scenarios. It offers 4K120 fps recording on every lens, Dolby Vision HDR, and 10-bit Log — features you’d expect from a high-end phone, yet there’s a catch.
Video enthusiasts can shoot up to 8K and enjoy a new Pro Video mode granting manual control over white balance, ISO, and more. Additionally, cinematic “Film Look” and “Film Style” modes apply film-inspired color profiles for polished footage. That’s the headline—now for the fine print.
Flagship Power, Mid-range Compromises
4K120 fps across all focal lengths is impressive on paper. Vivo’s Zeiss camera system spans 14 mm to 230 mm, covering an ultra-wide to super-telephoto zoom range. Image stabilization combines OIS and EIS, delivering smooth results comparable to Samsung’s Galaxy S25 Ultra in controlled conditions.
However, autofocus falters under fast movement. Running tests reveal hunting and lag, which can ruin otherwise stellar footage. This is no minor quirk—it’s a dealbreaker for action videography.
Pro Video Mode: Control vs. Complexity
The Pro Video mode is a solid addition, giving users granular control over exposure parameters. Yet, this feature feels half-baked without smooth autofocus to back it up. Manual settings only get you so far if the phone can’t keep subjects sharp in motion.
Film Look and Film Style modes attempt to mask weaknesses with stylized color grading, but they’re not substitutes for reliable core video performance.
How Stabilization Stacks Up
Stabilization is the X300 Ultra’s saving grace. Combined OIS and EIS keep footage steady even in shaky, rapid pan scenarios. Our analysis suggests Vivo’s solution narrowly rivals Samsung’s flagship, a big win for Android videographers.
Still, stabilization can’t compensate for focus hunting or occasional color inconsistencies noted elsewhere.
GizmoIndo’s Take
The Vivo X300 Ultra positions itself as a video powerhouse with specs that excite: 4K120 fps Dolby Vision recording, 8K capture, and extensive manual controls. Yet, the autofocus issues under dynamic conditions expose the gap between spec sheets and real-world use.
This phone will appeal to creators prioritizing resolution and color profiles, but those needing consistent autofocus during action might want to look elsewhere. Vivo’s stabilization tech is impressive, but shaky focus kills the deal for serious videography.
In a market chasing every frame per second and color bit-depth, the X300 Ultra is a reminder that reliability — especially autofocus — still matters most.
