HOW TO LONG TO SHORT VIDEO CLIPS AI AND FREE TO USE 2026

Step-by-Step AI Conversion Workflow

1.Import Your Long-Form Source Video:Supports YouTube URLs, Twitch links, or local MP4 files.

Paste your long-form video link directly into the AI tool (or upload the local video file). Works best with podcasts, interviews, speech-heavy vlogs, and educational videos.

2.Set Output Aspect Ratio & Preferences:Ensure 9:16 vertical formatting is selected.

Select 9:16 (Vertical) as your default canvas size. Set target clip durations (e.g., 15–30 seconds or 30–60 seconds) depending on your target social media platform.

3.Let AI Scan for Virality & Reframe Speakers:Processing typically takes 5–10 minutes for an hour of footage.

The AI generates a full audio transcription, scans for high-engagement "hooks" (emotional peaks, key takeaways, debate moments), and applies AI face-tracking to keep the active speaker centered in vertical mode.

4.Review AI Scores & Edit Captions:Edit captions by clicking directly on the transcript text.

Select clips with the highest AI virality scores. Review the auto-generated captions for minor spelling fixes, choose dynamic typography styles (Alex Hormozi-style animated text), and add automated B-roll or emojis.

5.Export and Publish:Export at 1080p resolution for optimal social algorithm reach.

Download the clips or connect your TikTok, YouTube Shorts, or Instagram Reels account directly to publish or schedule posts.
