Speeding up video on an iPhone is actually built right into the native tools—no need to clutter your storage with extra apps unless you’re going for a professional edit.
Fast-Track Your Footage
The “Slo-Mo” Fix: If it’s a Slow-Mo clip, open it in Photos > Edit and drag the two thick white bars in the timeline together to return it to normal speed.
The iMovie Rabbit: For standard videos, open iMovie, start a new project, and import your clip. Tap the Speedometer icon and slide it toward the rabbit to hit 2x speed.
The “Stacking” Hack: If 2x isn’t fast enough, export the 2x video, import that new file back into a fresh iMovie project, and speed it up again. This lets you reach 4x or 8x without buying third-party software.
Audio Check: If the “chipmunk” voice is ruining the vibe, go to Project Settings in iMovie and toggle Speed changes pitch off to keep audio sounding more natural.
