Auto Captions

Add Automatic Captions to Twitch Clips

EzClap adds automatic captions to your Twitch clips directly in the browser. Speech-to-text transcription generates the initial text, a word-level editor lets you fix any mistakes, and the captions are burned permanently into the exported video. No subtitle files, no external captioning tools — just captions that are always visible and styled the way you want.

How auto captions work in EzClap

Select a clip and start transcription

Pick any Twitch clip in your EzClap dashboard and start the auto-caption job. EzClap sends the audio through speech-to-text and returns a word-level transcript with timing automatically.

Review and edit in-browser

The caption editor shows every word with its timestamp. Fix any transcription errors, adjust timing if needed, and split or merge caption groups. Everything happens in the browser — no timeline scrubbing in a separate app.

Style your captions

Choose a font from the curated presets (or search all of Google Fonts on Pro), set the size, color, and outline. Save it as a named style profile tied to a game or content type — the same style applies to every clip in that category going forward.

Export with burned-in captions

EzClap renders the captions directly into the video frames. The exported file is a single video — no separate subtitle track, no SRT file to upload separately to TikTok or YouTube. The captions are always visible.

Caption features in detail

Speech-to-text transcription — no typing required

Auto captions are the only AI-powered feature in EzClap. Upload a clip and the transcription runs automatically. For most gaming clips, accuracy is high enough that you'll only need to fix the occasional missed word or game-specific term. For stream content with overlapping audio or loud game sounds, the editor gives you full control to correct anything.

Word-level timing control

Unlike simpler auto-caption tools that produce full lines at fixed intervals, EzClap's editor works at the individual word level. You can adjust when each word appears, which is important for gaming clips where reaction moments are timed precisely and the caption display needs to match.

Custom fonts and full Google Fonts search

Free accounts get a curated selection of fonts that work well for gaming content. Pro accounts unlock the full Google Fonts catalog — over a thousand fonts searchable directly in the caption style panel. Set a size, color, stroke, and shadow to match your brand, then save it.

Per-game caption style profiles

If you stream multiple games, you probably want different caption styles for each — different fonts, different colors, maybe a different size to account for different gameplay complexity on screen. EzClap lets you create named style profiles and assign them. When you process a clip tagged to a specific game, it picks up that game's profile automatically.

Word censor with sound effects

Define a list of words to censor. EzClap detects them in the transcript automatically and replaces the audio segment with a bleep or a custom sound effect you choose. The censored words are also hidden from the caption display. Useful for keeping content suitable for all-ages platforms or for covering language that might get flagged on TikTok or YouTube.

Batch captioning with Super Editor

Pro accounts can use the Super Editor to apply the same caption style and layout template to a batch of clips in one run. This is useful for processing a full session's worth of clips without going through each one individually.

Frequently asked questions

How do I add automatic captions to Twitch clips?

Log in to EzClap with your Twitch account, select a clip, and start the auto-caption job. The speech-to-text runs automatically, then you review and edit the result in the browser editor before exporting.

Are the captions burned into the video or saved as a separate file?

Burned in. The exported video has captions permanently embedded in the frames — no separate subtitle file to manage or re-upload when posting to YouTube Shorts or TikTok.

Can I customize the caption font and color?

Yes. Free accounts get a curated font selection; Pro accounts get full Google Fonts search. You control font, size, color, outline, and shadow. Save settings as style profiles that apply automatically per game or content type.

Does EzClap use AI for captions?

Yes — auto captions are the only AI feature in EzClap. The transcription uses speech-to-text to generate the initial text. You review and edit every word before anything is burned into the video.

Can I add captions to multiple Twitch clips at once?

Pro subscribers can batch-process multiple clips via the Super Editor, applying the same caption style and layout template in a single run. Free accounts process one clip at a time.
