Frequently Asked Questions
What is a vertical video converter?
A vertical video converter transforms horizontal (16:9) video into vertical (9:16) format suitable for TikTok, Instagram Reels, and YouTube Shorts. Smart converters like AutoClip use AI to track speakers and keep important content in frame — simple converters just crop from the center.
Does AI reframing cut off important content?
AutoClip's AI is designed to minimize content loss. Face detection keeps speakers in frame, and scene analysis prioritizes important visual elements. The result is significantly better than static center-crop.
What's the difference between cropping and reframing?
Static cropping cuts a fixed portion of the frame. AI reframing dynamically adjusts the crop position over time, tracking speakers and action like a virtual camera operator.
Does the vertical converter add captions?
Yes. AutoClip includes automatic caption generation with every clip, ensuring vertical videos are engaging even when watched on mute.
What resolution are the output clips?
AutoClip outputs vertical clips at up to 1080p × 1920p (Full HD vertical). Scale plan clips have no watermark.
Does the vertical video converter add captions?
Yes. AutoClip includes automatic AI speech-to-text-powered caption generation with every clip — captions are burned directly into the vertical video output.
Can I convert an entire YouTube channel to vertical automatically?
Yes. Channel monitoring watches any YouTube channel and automatically converts every new upload to vertical format, captions it, and posts it to your social accounts — completely hands-free.
