Auto-Resize Videos for All Social Platforms with AI

In today’s fragmented attention economy, your video must meet your audience where they are and in the format they expect. TikTok users scroll vertically. YouTube viewers expect cinematic 16:9. Instagram carousel videos need square 1:1.

Not optimizing for each format can cost you:

• Reach on platform-native feeds
• Engagement from format-conscious users
• Time spent editing the same video multiple times

Luma AI Reframe helps you auto-resize and reframe video content for all platforms in one go, saving time while maximizing visibility.

AI video resizing is more than just adjusting dimensions. Luma AI’s Reframe technology:

• Detects the key subject in your video (face, motion, or product)
• Dynamically adjusts the crop and framing per scene
• Outputs multiple aspect ratios optimized for vertical, square, widescreen, and everything in between

Instead of static crops, your AI-reframed video feels natural and platform-native, regardless of its original format.

Ideal output formats include:

• 9:16 for TikTok & Reels
• 16:9 for YouTube
• 1:1 for Instagram feed
• 4:5 for LinkedIn

Resizing and reframing videos with Luma AI is seamless:

Upload Once - Drop in your original 16:9 or 4:3 video.

Select Platforms or Aspect Ratios - Choose target outputs (e.g., TikTok, YouTube Shorts, Instagram).

AI Reframes Automatically - Luma AI analyzes movement, subjects, and composition to resize perfectly.

Download All Versions – Export reframed, high-quality videos instantly ready to post.

Whether you need 5-second vertical ads or long-form 16:9, Luma AI Reframe has it covered intelligently.

If you're creating video content and managing multiple platforms, this tool is for you:

• Content Creators: Reframe YouTube content for Shorts and Reels
• Social Media Managers: Publish fast without re-editing
• Brands & Startups: Create once, scale across channels
• Agencies: Save hours per campaign adapting videos for client platforms
• Educators & Trainers: Reformat lectures into mobile bite-sized content

With Luma AI Reframe, your content is always formatted right, without manual work.

Manual cropping often cuts out key parts of faces, gestures, or brand elements.

With AI-driven reframing, you get:

• Smart subject tracking
• Scene-aware crop adjustments
• Natural camera motion across formats
• Consistency across your brand’s videos

Your resized and reframed video doesn’t look edited; it looks purpose-built for the platform.

Manual editing tools require time, skills, and rework. Luma AI Reframe is built for scale and speed:

• No timeline scrubbing
• No re-rendering for every platform
• No aspect ratio guesswork
• No loss of subject focus

Luma AI automates resizing and reframing while protecting creative intent, making your workflow 10x faster and more effective.

Content doesn't need to be created three times for three platforms. With Luma AI Reframe, create once and publish everywhere in the right size, the right format, and the right context.

Upload your existing video, let AI auto-resize and reframe it for TikTok, YouTube, Reels, and more, and watch your reach grow across every channel.
