Overview
Video editing on a phone has to balance two things that pull against each other: a preview that responds instantly while you trim and add effects, and an export that keeps quality high without draining the battery.
As an iOS Developer at Yarsa Labs, I built this video editor for iPhone, covering trimming, effects, real-time preview and export at several resolutions.
Developed a video editing application with trimming, effects, and real-time preview using AVFoundation and AVKit. Implemented multi-resolution export options and smooth playback. Worked closely with design and product to ship a polished experience that met performance and quality targets.
