Frequently Asked Questions
What is Flixly's AI Auto Captions tool?
Flixly's AI Auto Captions tool automatically transcribes speech in your video and renders accurate, timed subtitles directly onto the footage. Upload a clip, choose a caption style (word-by-word, karaoke-highlight, scrolling, or classic), and download the captioned video ready for TikTok, Reels, or YouTube Shorts.
Which languages are supported for auto captions?
Auto Captions supports 80+ languages including English, Spanish, French, German, Italian, Portuguese, Japanese, Korean, Mandarin Chinese, Arabic, Hindi, and Russian. The speech-to-text model auto-detects the spoken language unless you override it.
How much does AI Auto Captions cost?
Flixly runs on pay-as-you-go credits. You get 10 free credits on signup, and captioning a short clip typically costs only a few credits. No monthly subscription required.
Can I customise the caption styling?
Yes. Pick from preset styles — word-by-word, karaoke-highlight, scrolling, and classic — and tune font, size, color, and outline to match your brand. Great for TikTok, Instagram Reels, YouTube Shorts, and LinkedIn video.
Does AI Auto Captions work for long videos?
Yes. The AI handles long-form content, though very long videos are chunked for reliability. Short-form content under 60 seconds is fastest and works best for social media.
