🚀 How to Get Started
1. Upload Your Video - Choose your video file or paste a video URL to begin the resize process.
💡 Tips for Better Results
Choose the Right Aspect Ratio
Match your target platform: 9:16 for vertical social (TikTok, Reels, Stories), 1:1 for Instagram posts, 16:9 for YouTube landscape, 4:3 for classic Facebook.
Consider Content Positioning
Ensure important subjects are centered in your original video. AI framing works best when key elements are positioned in the middle third of the frame.
Optimize for Each Platform
Resize the same video to multiple formats to maximize reach. Create vertical, square, and landscape versions for complete social media coverage.
Test Before Posting
Preview resized videos before downloading to ensure framing meets your expectations. Use the "Reframe" button to regenerate if needed.
