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

Complete a render in Studio Mode or Autopilot
The Render Complete dialog appears automatically
Under 📐 Export Formats, you’ll see buttons for each format
Click Export next to the format you want
The re-crop runs in the background (typically 10–30 seconds)
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:

Reads the EDL’s face data — during rendering, every clip is analyzed for face positions using MediaPipe
Averages all face positions across the entire edit to find the dominant subject area
Centers the crop on that position, with clamping to prevent edge overflow

If no face data is available, the engine falls back to a slightly above-center crop point (0.5, 0.4), which works well for typical human framing.

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.
