Why Subtitles Matter
Captions turn a silent scroll into a conversation. They let viewers watch on mute, improve SEO, and make your content accessible to the deaf community. A tight 30‑second hook followed by clear subtitles keeps attention high and signals the algorithm that your video is valuable.
Structure matters: start with a punchy intro, deliver the main steps, and close with a call‑to‑action. Keep each subtitle line under 42 characters so it reads comfortably on mobile screens. For vertical Shorts, aim for 9:16; for YouTube tutorials, 16:9 works best.
Creating Subtitles with Vaideo
If you want a brand‑new video, choose “Create with AI.” Type your topic, pick a voice, and Vaideo will write a script, add stock or AI‑generated visuals, and automatically generate captions. The result is a ready‑to‑publish video with subtitles baked in.
For existing footage, open Vaideo Editor (free for all users). Upload your clip, click “Generate subtitles,” and the AI will transcribe and sync text to the audio. You can tweak timing, font, and color, then export in 1080p without a watermark if you have a pack or Pro plan.
Common Pitfalls & Variations
Automatic transcription can mis‑hear slang, acronyms, or fast speech. Always review the generated text and correct errors before publishing. Also, avoid long sentences that overflow the screen; break them into bite‑size lines.
If you need captions in another language, select the desired voice language when you create the video or change the subtitle language in the editor. Remember that the free plan only supports up to 30‑second videos, so longer tutorials require a pack or Pro subscription.
