Frequently Asked Questions

How accurate are AutoClip's captions?

AutoClip uses Deepgram, an industry-leading speech-to-text provider. Accuracy is high across accents, audio quality levels, and content types.

Can I customize the caption style?

Yes, multiple caption styles are available. Pro and Scale plans include additional customization options for font, size, color, and animation style.

Are captions added automatically to every clip?

Yes, captions are generated and burned into every clip by default. No extra steps required — the auto-caption generator runs as part of the standard clip pipeline.

Why do short-form videos need captions?

Over 80% of social media videos are watched on mute. Without captions, the majority of viewers who encounter your clip without sound will scroll past without understanding the content.

Are captions burned into the video or added as a separate file?

Captions are burned directly into the video file in AutoClip. This ensures they display correctly on every platform — TikTok, Instagram Reels, YouTube Shorts — without any compatibility issues.

Does the auto caption generator work for non-English content?

Deepgram supports major languages. English has the highest accuracy. For non-English content, transcription quality may vary but the captioning pipeline works the same way.
