Subtitle overlay on video
Overlay custom subtitle objects onto MOV and MP4 video files, with controls for text, container geometry, margins, background color, corner radius, and rotation.
Quick Sub 2
Quick Sub 2 is a Mac subtitle editing app for MOV and MP4 files, with separate text and container controls, native .qsub2 saving, and export progress monitoring.
Overview
Quick Sub 2 is a Mac app for adding and styling subtitle objects directly on video files. The App Store listing describes it as a streamlined tool for working with MOV and MP4 sources while keeping text, container shape, and timing controls separate.
Its workflow is built around precise visual editing: users can adjust typography, colors, alignment, margins, corner radius, rotation, and on-canvas placement. The app also supports project persistence through the .qsub2 file format and includes export progress monitoring for rendered output.
Key features
Separate text and container control
Edit font family, typography, color, and alignment separately from the subtitle container so text and layout can be tuned independently.
Batch style adjustments
Apply size and style parameters to multiple subtitle objects with a single menu command to reduce repetitive editing.
Undo and redo support
Use an integrated Undo Manager with full history support, making iterative layout and timing changes reversible.
Native project files
Save work in the native .qsub2 format and restore a workspace by opening the file directly in the app.
Controlled video export
Export rendered video with real-time progress monitoring, and stop the export process if needed.
Common use cases
Subtitle design for Mac video projects
Create subtitles for MOV or MP4 videos when you need control over text styling, container shape, and on-screen placement in the same workspace.
Timing and placement adjustments
Refine subtitle timing by dragging objects along the timeline and repositioning them directly on the movie canvas.
Batch formatting across many subtitles
Build visually consistent subtitle sets by applying the same size and style settings to multiple objects at once.
Trial-and-error editing
Iterate on a project safely by relying on undo and redo while testing different font, color, rotation, and layout combinations.
Project-based subtitle workflow
Save a subtitle project in .qsub2 format, reopen it later, and export the finished video when edits are complete.
