Change the frame rate of a video to 24, 30 or 60 fps

Overview

Pick a video and a new frame rate: 15, 24, 25, 30, 50 or 60 fps. The length of the video does not change; only how many pictures are shown each second. Then choose how iEdit should get from the old rate to the new one. Sharp drops frames when going down and repeats them when going up, so every frame remains an untouched original. Smooth blends neighbouring frames to create the in-between ones, which looks more fluid in motion but softens fast-moving detail slightly.

Going down, say from 60 to 30 or 24 fps, is the usual direction: it gives a more filmic look, halves the frames to encode and can make a smaller file. Going up to 50 or 60 fps makes a clip match a project or a display that expects it. Encoding is done by the phone's hardware encoder in H.264 or HEVC at the source resolution, with location, device and date metadata kept and HDR saved as SDR. The job shows progress, can be cancelled, and finishes in the background.

Change FPS when mixed footage has to sit together, when 24 fps is wanted for a film look, when a 25 fps PAL clip needs to become 30 or a 60 fps game capture should be 30 for a smaller upload. For changing how fast the action plays rather than how many frames show it, Speed is the right tool. Everything runs on your device; nothing is uploaded.
