Vivo X300 Ultra Delivers 4K120 Video as Autofocus Stumbles in Fast-Motion Tests

4K30 Dolby Vision test footage showed the Vivo X300 Ultra delivers highly detailed video and strong stabilization, even under rapid pans and heavy shaking.
OIS plus EIS kept performance roughly on par with Samsung’s Galaxy S25 Ultra, while Vivo also supports 4K120 across all focal lengths, 120 fps in Dolby Vision and 10-bit Log, and up to 8K capture.
14 mm-to-230 mm shooting gave videographers broad range in testing, with clips recorded at 0.6x, 1.5x, 3.7x, 7.4x and 10x zoom.
Fast running shots exposed the main weakness: autofocus struggled to lock reliably during quick movement, including in footage captured with Vivo’s Film Look mode.
New Pro Video controls for white balance and ISO, plus Film Look and Film Style profiles, position the phone as a serious video tool despite that focus limitation.
Why does the Vivo X300 Ultra’s advanced AI camera fail at autofocus during fast-paced action?
Do the X300 Ultra's pro manual controls make its autofocus issues irrelevant for creators?
