Multi-Format Export

Overview

After rendering your video, Onset Engine can re-crop it to different aspect ratios for social media platforms - all with a single click. The re-crop uses face-aware centering from your edit’s face detection data to keep subjects in frame.

Supported Formats

Format	Resolution	Best For
9:16 Vertical	1080×1920	TikTok, Instagram Reels, YouTube Shorts
1:1 Square	1080×1080	Instagram Feed
4:5 Portrait	1080×1350	Instagram Portrait

All formats output in 1080p quality using the same encoder (NVENC or x264) and quality parameters as your main render.

How to Use

1. Complete a render in the Editor or New video
2. The Render Complete dialog appears automatically
3. Under 📐 Export Formats, you’ll see buttons for each format
4. Click Export next to the format you want
5. The re-crop runs in the background (typically 10–30 seconds)
6. Status updates to ✅ Ready with the output file size

You can export to multiple formats - each runs independently.

Face-Aware Framing

When cropping from 16:9 to a taller or narrower format, the engine needs to decide where to crop. Instead of dead-center cropping (which often cuts off faces), Onset Engine:

1. Finds the cuts in your video, so every shot is framed on its own
2. Finds the face in each shot, a few times a second
3. Follows it: the crop holds still while the subject stays near the middle and moves smoothly when they move away, and it never runs off the edge of the frame

Shots without a face are framed on your edit’s usual subject position, or slightly above center when there is none. Looking for faces adds a few seconds to each export.

The Vertical format in the Editor frames every clip the same way while it renders.

Output Files

Re-cropped files are saved alongside your main render with a format suffix:

output_clips/MyProject/
├── output_STANDARD.mp4          # Original 16:9 render
├── output_STANDARD_9x16.mp4     # TikTok / Reels / Shorts
├── output_STANDARD_1x1.mp4      # Instagram Feed
└── output_STANDARD_4x5.mp4      # Instagram Portrait

Audio is copied directly from the original render - no re-encoding, no quality loss.

Tip

Export all three formats at once if you publish to multiple platforms. The re-crop is fast (it doesn’t re-render the video - it only re-frames and re-encodes) and each format is independent.
