Hard subtitles vs soft subtitles
Choose the export that fits your platform. Both preserve your fonts, colors, and layout from the style editor.
Soft subtitles (switchable)
- MKV with embedded styled ASS subtitle track
- Toggle on/off in compatible players
- Dual original + translation tracks when both exist
- Best when viewers choose language or turn captions off
Visual style editor
Drag and resize the subtitle text box directly on your video frame. Pick fonts by script, tune colors and outline, and set background opacity — with smart defaults for portrait and landscape.
- Draggable, resizable subtitle box on the video
- Font library: Latin, Arabic/Persian, Hebrew, Indic + auto language default
- Text, outline, and background color with opacity control
- Box width drives line wrapping and automatic chunking
👁️Preview parity
What you see is what you export
The preview overlay uses the same layout math as the export pipeline — font size is computed for your video’s native resolution, not the preview panel size. Styled hardsub output matches the editor preview.
Export formats
Every export path is included free for platform users — subtitle files, burned-in video, soft tracks, and dubbed audio with optional subtitles.
Subtitle files — SRT & WebVTT
Instant download of original or translated tracks for YouTube, editors, and CMS workflows.
Hardsub video — styled MP4
Burn styled subtitles into MP4 with libass — ready for social and universal playback.
Softsub video — styled MKV
Mux styled ASS tracks into MKV; dual-language tracks when translation exists.
Audio + subtitles on dub exports
Export MP3 or MP4 with dubbed audio and optional styled subtitles — timings remapped to TTS playback.
Sync, chunking & timing
Fix drift, split cues, and keep lines readable — with the same chunking logic in preview, file export, and video burn-in.
Full & partial resync
Shift all subtitles by milliseconds, or resync only the segment range that drifted after a re-edit.
Split at playhead & add segments
Split a cue at the current time or insert a new segment without leaving the timeline.
Box-aware chunking
Long cues split into readable lines based on your subtitle box width, font size, and portrait vs landscape layout.
Dub-aware timing
When exporting with TTS voiceover, subtitle timings remap to match synthesized speech.
RTL & global scripts
Arabic, Hebrew, and Persian are auto-detected with RTL direction, script-appropriate fonts, and proper shaping in both preview and export — hardsub and softsub.
🎙️Dubbing projects
Per-segment export modes
In dubbing workflows, control how each segment appears in the final export:
Voiceover (default)
Segment is dubbed with AI voice — standard for dialogue and narration.
Hard-sub caption
Keep original audio but burn translation as on-screen text — ideal for lyrics, poetry, or quoted speech.
Hidden from export
Exclude a segment from the exported video or subtitle track when it should not appear.

Subtitles — Frequently Asked Questions
What is the difference between hardsub and softsub?
Hard subtitles are burned into the video pixels — always visible, compatible with every player. Soft subtitles live in a separate MKV track so viewers can toggle captions or switch languages. Both support your custom fonts, colors, and box layout from the style editor.
Are subtitle exports free?
Yes. Downloading SRT/WebVTT files and exporting styled MP4 hardsub or MKV softsub is included free for all videodubbing.com users — no separate export fee.
Which format should I use for YouTube or social media?
Upload SRT or VTT to YouTube as separate captions, or export MP4 hardsub when captions must be baked in. For TikTok, Reels, and Shorts, hardsub MP4 is usually best. Use MKV softsub when you want toggleable or dual-language tracks.
Does videodubbing.com support Arabic and RTL subtitles?
Yes. Arabic, Hebrew, and Persian are auto-detected with RTL layout, script-appropriate fonts, and proper shaping in preview and export. For fixing direction in existing files, use our free RTL Subtitle Fixer.
What is the difference between SRT, VTT, and burned-in subtitles?
SRT and WebVTT are editable subtitle files — upload them to platforms or mux as soft tracks. Burned-in subtitles are rendered into the video and cannot be turned off, but they work on every device and social feed.
