|
|
| 1. Download `Nugget Video Trimmer vX.X.html` |

|
| ## What it does |
|
|
| **Trim** — scrub a filmstrip timeline, drag in/out handles, step frame by frame, or type exact times. A slim bar under the timeline slides the whole selection without changing its length. |
|
|
| **Multi-clip** — queue several cuts from one video and export them all at once into a folder you choose. |
|
|
| **Crop** — draggable box with ratio presets (16:9, 9:16, 1:1, 4:5, 2:3, 21:9, custom…). |
|
|
| **Resize & frame rate** — percentage presets or exact pixels; any fps. |
|
|
| **Compression** — one slider, smaller file ↔ bigger file, with a live size estimate. |
|
|
| **Pictures** — single-frame snapshot, animated GIF, and two kinds of contact sheet: |
| - *Auto storyboard* — N×N frames spread evenly across the selection |
| - *Manual storyboard* — pick the exact frames yourself, with thumbnails |

| ## Outputs |
|
|
| | | Format | |
| |---|---| |
| | Video | MP4 (H.264 + AAC), WebM fallback | |
| | Pictures | PNG | |
| | Animation | GIF | |
|
|
| Files are named from the source, timestamp and settings, e.g. `holiday_1m37s_1280x720_30fps.mp4`. |

|
| ## Good to know |
|
|
| - **Export runs in real time** — a 30-second clip takes about 30 seconds. Keep the tab on screen; it pauses if you switch away and resumes when you return. |
| - **It re-encodes**, so output isn't bit-identical to the source. The compression slider controls that trade-off. |
| - **GIF is 256 colours** and grows quickly — smaller width and 10–15 fps work best. |
| - Manual storyboards hold up to 25 frames; grids go to 10 × 10. |

| ## Requirements |
|
|
| Chrome or Edge. Firefox mostly works but falls back to WebM. No server, no dependencies, no build step. |
