AutoResize automatically adapts your videos to the right format for each platform (TikTok, Reels, Shorts, & more) while keeping your subject perfectly centered using AI tracking.
Watch our YouTube tutorial to get started :

Step 1 - Define your desired format

Use AutoResize’s preview window to:

• Choose your target format (9:16, 1:1, 4:5, etc.)
• Adjust the subject speed to define how quickly the AI should follow movement within the frame

AutoResize will then track your subject and adapt the framing accordingly.

Step 2 - Add your watermark

You can easily import your own watermark and position it exactly where you want: top corner, center, bottom, etc. Once set, AutoResize will apply your framing, format, and watermark consistently across your entire sequence.
