Many Shorts get watched muted. If the words are not on screen, the tip dies in two seconds. That is why SRT captions matter — not as decoration, but as a retention and accessibility tool.
This page is the “why” plus how to export SRT with your voiceover. It is not a full CapCut import click-path — those steps live in the Phase 1/2 CapCut guides linked below.
What is an SRT file?
SRT is a plain subtitle format: numbered cues, start/end timestamps, then text. CapCut, Premiere, and YouTube Studio all accept it. You do not need fancy styling inside the file — style happens in the editor or on YouTube.
What a clean cue looks like
Each cue is short — one or two phrases, not a paragraph. Timestamps should match the spoken take. If you regenerate the MP3, regenerate (or replace) the SRT too. Mixing take A audio with take B captions is how drift starts.
Why captions help Shorts
- Muted scrollers can still follow the tip
- Hard-of-hearing viewers stay in the story
- On-screen text reinforces numbers, names, and CTAs
- Packaging looks finished instead of “forgot captions”
- You reuse one SRT for burn-in and for YouTube upload
Captions do not replace a strong hook. They support retention after the hook lands. Bad first two seconds still lose the viewer — with or without SRT.
Export SRT with your AI voiceover
In Shorts Voice Studio, turn SRT on before you generate. You download MP3 and captions from the same take — no separate transcription round-trip.
- Write or paste a Shorts-length script (under 700 characters per generate)
- Pick voice and mood, lock the series voice
- Enable SRT captions
- Generate and listen once on a phone speaker
- Download MP3 + SRT together
- Burn in via CapCut, or upload SRT in YouTube Studio (or both)
Burn-in vs uploaded SRT
Burn-in means captions are part of the video pixels. Uploaded SRT means YouTube shows a separate caption track you can edit later.
- Burn-in: best for TikTok, Reels, and muted feeds where you want text guaranteed
- Uploaded SRT: easier typo fixes on YouTube without re-exporting
- Same source file: generate SRT once with the voiceover, then choose the path
Many creators burn in for multi-platform posts and also upload the same SRT on YouTube when they want an editable track. You do not need both every time — pick what matches where the video lives.
Caption tips for mobile screens
- Keep lines short (1–2 phrases per cue)
- Fix names, numbers, and brand spellings once
- Leave safe margins away from bottom UI and usernames
- Do not cover faces, product UI, or the CTA card
- Match timing to speech — no long empty gaps after the last word
- Watch the cut muted once before you schedule
Auto-captions vs your exported SRT
Platform or CapCut auto-captions are fine for a rough draft. If you already exported SRT with the voiceover, prefer that file. You paid the timing once. Re-running auto-captions invites spelling drift on brands, apps, and Hindi/Hinglish mix lines.
Where to go next (import + CapCut)
Once the SRT is on disk, the remaining job is import and style. Keep this page for the “why + export” decision. Use the dedicated guides for menus and timeline steps.
Honest limits
- SRT must match the final audio take — regenerate both if you change the script
- Each Studio generate is capped at 700 characters; section longer scripts
- We do not burn captions into video inside Studio — that happens in your editor
- Free credits run out on daily publishing; plan packs for caption-heavy weeks
FAQ
Should I burn captions in or upload SRT?
Burn-in for TikTok/Reels-style platforms and guaranteed muted text. Upload SRT on YouTube when you want an editable track. Many creators do both from one file.
Do captions replace a good hook?
No. Captions support retention. The first two seconds still need a strong visual and verbal hook.
When should I enable SRT in Studio?
Before you generate. Turning it on after the fact does not attach captions to an old take — generate with SRT enabled.
Why do my captions drift from the audio?
Almost always a mismatched pair — old SRT with a new MP3, or a trim on audio without shifting captions. Re-download the pair from the same generate.
Is this the CapCut import tutorial?
No. This page covers why SRT matters and how to export it. For CapCut menus and YouTube Studio upload steps, use the import guide linked above.
Export SRT with the voice take. Style it later. Never mix yesterday’s captions with today’s audio.
Turn SRT on before generate, download the pair, then burn in or upload — do not retype captions from scratch.
