Creator workflow
Prepare captions before publishing
Use Voice2Sub before your video goes live. Export the final edit from your video editor, generate a subtitle draft locally, review it, then save SRT or VTT for the publishing step.
- Final video exports
- Caption drafts
- SRT/VTT handoff
Own videos
Designed for videos you own or can process
The page is intentionally positioned around your own local video files. It does not claim to download or transcribe YouTube URLs. That keeps the workflow clear for creators, editors and teams preparing captions for their own content.
- Local files only
- No paste-a-link workflow
- Review before upload
Format choice
SRT and VTT cover most caption handoffs
SRT is a practical default for many publishing and editing workflows. VTT is useful when a web player or web caption pipeline expects WebVTT. Voice2Sub keeps both options visible after the AI draft has been reviewed.
- SRT for broad compatibility
- VTT for web captions
- TXT for transcript notes
Quality pass
Review captions like part of the video edit
Subtitles affect viewer trust. Before using an exported file, check names, acronyms, product terms, line length and timing. Treat the subtitle pass like a normal review step in your publishing checklist.
- Names and acronyms
- Line length
- Timing and readability
