Where Does All Your Time Go?

Filming, editing, color grading, designing thumbnails, writing titles, optimizing for SEO — getting a single video from camera to upload already takes hours of post-production work.

And then there are subtitles.

Typing out a full transcript for a 10-minute video can easily take 30 minutes or more. Want to add subtitles in other languages to reach a global audience? That's a whole separate project.

Most YouTubers just skip subtitles entirely. Or they rely on YouTube's auto-generated captions and hope for the best.

The Problem with YouTube Auto-Captions

YouTube's auto-captions have improved over the years, but according to multiple studies, they're only about 60-70% accurate. What does that mean in practice? A 30-minute video contains roughly 4,500 words. With 60-70% accuracy, over 1,500 words could be wrong — almost every single caption line needs fixing. Sitting down to replay, listen, and correct each one easily takes 1.5 to 2 hours.

By comparison, Hey Subtitle's AI transcription achieves over 95% accuracy. For the same 30-minute video, you'd only need to fix around 200 words — about 15 minutes of proofreading.

Beyond accuracy, YouTube auto-captions have other limitations:

Poor translation quality — YouTube does have an Auto-translate feature, but it translates based on the original captions. When those captions are only 60-70% accurate, the translations are even worse. And each additional language means another 1.5-2 hours of manual corrections — two languages means 3-4 extra hours. With Hey Subtitle, translations are based on your 95%-accurate source, so translation quality is high and almost no corrections are needed
Clunky editing experience — YouTube Studio's subtitle editor is cumbersome and doesn't let you edit while watching the video side by side

Step-by-Step Guide

Step 1: Upload Your Video or Paste a YouTube URL

After logging in, click "Upload Video." You can upload a video file directly, or switch to YouTube URL mode and paste your link. Select the source language of your video (e.g., "English").

Step 2: Wait for AI Transcription

The system automatically processes the audio and generates subtitles. This usually takes just a few minutes depending on video length. You can track progress on the video list page.

Step 3: Review in the Editor

Click the subtitle language to open the editor. Subtitles are already synced to the video timeline. AI accuracy is high — just click to edit the occasional word that needs fixing.

Step 4: Add Multilingual Translations

Back on the video list, click "Translate" and select your target languages (e.g., Japanese, Chinese). Translation is handled by AI and doesn't consume your transcription minutes.

Step 5: Export and Upload

Export SRT files from the editor, then upload them in YouTube Studio. Export one file per language, and your viewers can switch subtitle languages freely.

Supports 50+ Languages

Hey Subtitle supports speech recognition for over 50 languages, including English, Cantonese, Mandarin, Japanese, Korean, French, German, Spanish, and many more. Whatever language your video is in, the AI can transcribe it accurately.

Translation works across all supported languages too. For example, you can translate an English video into Japanese, Chinese, Korean, and more — all with a single click.

Multiple Export Formats

Beyond the most common SRT format, Hey Subtitle also supports:

SRT — The universal standard, supported by YouTube, Vimeo, Facebook, and more
VTT — The standard format for web video players
FCPXML — For Final Cut Pro users, with customizable FPS and resolution settings
TXT — Plain text transcript, great for repurposing into blog posts or articles

Different platforms need different formats — export them all in one place.
