Why Manual Subtitling Fails (And Costs You Viewers)
Time Consuming
Manual transcription takes 4-6 hours for a 10-minute video. Time you could spend creating more content.
High Cost
Professional subtitle services charge $5-15 per minute. Costs add up quickly for regular content creators.
Limited Audience Reach
85% of videos are watched without sound. Without subtitles, you're losing most of your potential audience.

Frequently Asked Questions (FAQ)
How accurate is the AI translation?+
Our AI achieves 99% accuracy for transcription and professional-level translation quality comparable to human translators. We use state-of-the-art neural machine translation models trained on billions of multilingual text samples. For critical content, we recommend using our built-in editor to review and refine the output.
What video formats do you support?+
We support all major video formats including MP4, MOV, AVI, MKV, WebM, and more. You can also directly import videos from YouTube, Vimeo, or other platforms by pasting the URL. Maximum file size is 5GB on the free plan and unlimited on paid plans.
How long does it take to generate subtitles?+
Processing time is typically 1/4 the length of your video. A 10-minute video will have subtitles ready in about 2-3 minutes. This includes transcription, translation, and timeline synchronization. Longer videos may take proportionally longer, but you'll always get results much faster than manual subtitling.
Can I edit the subtitles after generation?+
Absolutely! Our online subtitle editor allows you to make any changes you need. Edit text, adjust timing, split or merge subtitle segments, and customize styling (font, size, color, position). All changes are made in real-time with instant preview alongside your video.
