VidSub: Video Subtitle Creator for iPhone

VidSub — iPhone Captioning Suite

VidSub is a free iPhone application built to help creators produce and refine captions and subtitles quickly. It supports both exporting standard subtitle files and embedding captions directly into video files, making it compatible with many playback environments.

Core features

• Create subtitles by speaking: built-in speech-to-text turns spoken words into timed captions to speed up input.
• Export options include standard SRT files or permanently burning captions into the video.
• Integrated video player that handles multiple container types, including MKV, for real-time preview and editing.
• Flexible visual styling with adjustable fonts and on-screen appearance controls.
• Timestamp capture and bulk timing edits to synchronize large subtitle sets efficiently.
• Tools to convert between subtitle formats and to extract subtitle tracks from video files.

How it accelerates workflow

VidSub reduces manual typing by offering voice-driven captioning and an in-app player so you can hear, edit, and check subtitles without switching apps. Batch timing adjustments and automatic timestamp capture make aligning long transcripts much faster.

Supported formats and playback

The app works with common media containers and delivers subtitles in player-friendly formats. You can:

• Produce SRT files for use in external players and platforms.
• Embed captions directly into the video for devices or players that do not support external subtitle tracks.
• Play and edit videos in popular formats (including MKV) inside the app for immediate verification.

Advanced editing and export

For more complex needs, VidSub includes:

• Conversion utilities to switch between subtitle standards.
• Extraction options to pull embedded subtitle tracks from existing videos.
• A burn-in feature to render captions permanently onto the picture when required.

Who should use VidSub

This app is a good match for videographers, social media creators, translators, and anyone who needs an easy, all-in-one tool to produce accurate captions on an iPhone. Its combination of voice-to-text, in-app playback, and flexible export makes subtitling faster and more convenient.
