How Browser-Based Subtitle Processing Works
VidStudio uses FFmpeg compiled to WebAssembly to handle all subtitle and text operations directly in your browser. Upload a video and subtitle file, choose your processing mode, and get results without any server uploads. Whether you are burning SRT captions into a video, adding styled ASS subtitles, extracting existing tracks, or creating animated text effects, the processing runs locally on your device. This means your content stays private and there are no file size limits imposed by a server.
About Subtitles & Text
Text Overlay
Add custom text directly to video with FFmpeg's drawtext filter. Control font, color, position, timing, and display dynamic content like timecodes.
Subtitle Files
Work with standard subtitle formats (SRT, ASS, VTT). Burn subtitles into video, add as separate tracks, extract from videos, or convert between formats.
Text Effects
Create animated text like scrolling credits, typing reveals, and fade effects. Perfect for intros, outros, and creative video content.
Common Use Cases
Add Captions for Accessibility
Burn-in or embed subtitle tracks to make your videos accessible to deaf and hard-of-hearing viewers.
Social Media Captions
Add permanent burned-in captions for platforms where viewers watch with sound off, like Instagram and TikTok.
Video Intros & Credits
Create professional-looking title sequences and scrolling end credits with animated text effects.
Translate Subtitles
Extract existing subtitle tracks, translate the text, and burn the new subtitles back into the video.
