Quick Sub 2: Video Subtitling
Quick Sub 2 is a native macOS video subtitling application built in SwiftUI for video creators and editors. It allows users to place, style, and position subtitle objects over MOV and MP4 video files using direct canvas drag manipulation and rotation controls. The app separates text styling from container geometry, giving creators independent authority over font families, margins, background colors, corner radii, and angles. Projects can be saved natively using the .qsub2 file format or exported to standard SRT subtitle files.
What it does
Positions subtitle text layers via direct canvas drag-and-drop and rotation angle adjustments. Separates text formatting from container geometry, background colors, and corner radius settings. Scales dynamic timeline views from 0.1x to 10x zoom factors for precise frame-level alignment. Exports composite hardcoded subtitled videos or standalone .srt transcript files to disk.
Why it works
SwiftUI native architecture ensures fast rendering and fluid performance on modern macOS devices. Direct canvas manipulation eliminates tedious manual x/y coordinate inputs found in traditional NLEs. Native .qsub2 project persistence and SRT exports provide flexible workflow interoperability. On-device rendering operates entirely offline without uploading media files to cloud servers.

Founder story
Quick Sub 2 was created in 2026 by Japanese macOS application developer Tomoyuki Okawa. Built to fix the tedious overlaying and rigid styling workflows in massive video editing suites, Okawa re-engineered Quick Sub from the ground up using SwiftUI to give creators granular, independent control over text styling, rotation angles, and timeline timing.
