Frequently Asked Questions
Can I auto-generate subtitles from my video?
Yes. Subtitle Editor can generate a first draft directly from your video’s audio in one click. It works best when speech is clear, and you can refine text and timing inside the editor.
Can I upload existing subtitle files?
Absolutely. You can upload SRT and VTT files created in other tools or provided by translators. After uploading, you can edit timing, text, and readability settings within the editor.
What are WPM and CPS, and do I need to understand them?
WPM (Words Per Minute) and CPS (Characters Per Second) measure subtitle reading speed. You don’t need technical knowledge — the editor shows simple color indicators (green, orange, red) and explains when captions are too fast or too dense.
Can I save subtitles as draft before publishing?
Yes. You can save subtitles as draft, continue editing later, and publish when ready. You can also publish multiple drafts at once.
Can I manage subtitles for multiple speakers?
Yes. Auto-generated subtitles can label speakers (e.g., S1, S2). You can filter by speaker, assign or edit labels, and export subtitles for a specific speaker only.
