Vs auto-captions

Caption-Lagao vs in-app auto-captions

TikTok, Reels, and YouTube auto-captions help some viewers. They are the wrong tool when you need Roman Urdu, a style you picked, and a file that still has captions after a share.

Need	Platform auto-captions	Caption-Lagao
Urdu speech on screen	Often Hindi Devanagari or a stiff translation	Roman Urdu, then you edit mixed English
Timing	Late sentence blocks	Word timestamps for karaoke and highlights
Stay on a repost	Usually lost when someone saves the file	Burned into the MP4
Account	Platform login	None
Export	Stuck in the app	MP4 plus SRT, VTT, ASS, or TXT — no watermark

Why Roman Urdu captions are different

Auto-detect often writes Hindi Devanagari for Urdu speech. Roman Urdu uses Latin letters — the same script as comments and chats — so a mute Reel can still be read at a glance.

What you receive on export

A captioned MP4 with the style you previewed, and optional SRT, VTT, ASS, or TXT. Exports do not add a Caption-Lagao watermark. Timing is only as good as the audio — edit before you post.

Caption generator FAQ

How do I add captions to a short video for free?

Upload an MP4, MOV, or WEBM on the create page, generate captions, edit any line, pick a style, then export a burned-in MP4 and an SRT file. No account is required.

Does Caption-Lagao support Roman Urdu and mixed Urdu–English speech?

Yes. Spoken Urdu can be written as Roman Urdu (Latin letters). English words, brand names, and numbers stay as spoken. You can also output English or other languages from the same transcript.

Are the captions word-timed?

Yes. Each word gets a start and end time from speech-to-text, so karaoke and highlighter styles can follow the voice instead of dumping a late paragraph on screen.

What happens to the video I upload?

The video file stays on this device in local storage. Audio is sent to generate the transcript. Caption-Lagao does not require an account, and projects are not published to a public gallery.

What do I get when I export?

A burned-in MP4 with the styled captions in the picture, plus optional SRT, VTT, ASS, and TXT. Exports do not add a Caption-Lagao watermark.

How accurate are the captions?

Timing and wording depend on audio quality, overlapping speakers, and background noise. You can edit any caption or word in the timeline before you export. Treat the first pass as a draft.

Do I need an account or an app download?

No. Caption-Lagao runs in the browser. There is no sign-in wall and nothing to install. Projects stay on this device.

Which file formats can I upload?

Video: MP4, MOV, WEBM, MKV, AVI, M4V. Audio: MP3, WAV, M4A, AAC. Files up to 200 MB. Shorter talking clips caption more cleanly than long, noisy recordings.

Can I add captions to a Reel or TikTok I already filmed?

Yes. Save or export the draft as MP4, drop it here, generate captions, then download a burned-in file to post. In-app auto-captions are not required.

What is the difference between burned-in captions and SRT?

Burned-in captions are pixels in the MP4 — they show even if someone watches on mute or reposts the file. An SRT is a separate subtitle file for YouTube’s caption track. You can export both from the same project.

Do I need to download an Urdu caption generator app?

No. Caption-Lagao runs in the browser — there is no APK, no App Store listing, and nothing to install. Open the site, upload the video, export a captioned MP4.

Does Caption-Lagao write Instagram photo captions or quotes?

No. It captions speech on video (Reels, TikTok, Shorts, YouTube). It does not write photo captions, birthday quotes, England captions, or Instagram bio copy.
