What this page covers
vdoflow does not author subtitles yet, so this page is about preparing the video cleanly before you move into captioning elsewhere.
Use vdoflow to prepare clean subtitle-ready video outputs while direct subtitle authoring is not available yet.
When add subtitles is the right tool
- Trim and crop before captioning so subtitle timing matches the final edit
- Prepare a broadly compatible MP4 handoff
- Keep spoken content clear when transcription or manual captioning is next
Common mistake to avoid
Do not start captioning before the edit is stable. Any timing change later makes subtitle work harder than it needs to be.
How this differs from nearby tools
This is a preparation workflow, not a subtitle editor. Use vdoflow to clean the file before you subtitle it somewhere else.
Start with trim or convert so the file is already close to the final version before captioning begins.
