Stream Toolbox turns long videos into short vertical clips. It keeps **selection, reframing, review, and output** in one operator workspace.

## Visual Proof

Start with a source. Finish with organized, reviewable output.

## Outcome Flow

  accTitle: Stream Toolbox Outcome Flow
  accDescr: A source video moves through moment selection, vertical framing, review, and organized output.
  source["<strong>Source Video</strong><br/><small>URL Or Upload</small>"] --> select["<strong>Find Strong Moments</strong><br/><small>Create Candidates</small>"]
  select --> reframe["<strong>Frame For Vertical</strong><br/><small>Keep The Subject Clear</small>"]
  reframe --> review["<strong>Review Clips</strong><br/><small>Check Media And Details</small>"]
  review --> output["<strong>Organize Output</strong><br/><small>Ready For The Next Step</small>"]
```

1. Add a URL or upload a video.
2. Find strong moments and create vertical candidates.
3. Keep the subject framed without distracting camera motion.
4. Review clips, thumbnails, and metadata together.
5. Retry failed work without restarting the whole job.

Each stage has a clear input and output. Implementation details stay encapsulated behind the workflow.

## Reframing Engine

The reframing engine follows the subject inside a stable safe area. It moves only when the composition needs correction.

Fallback framing keeps output usable when confident tracking is unavailable. The result favors watchable motion over constant correction.

## Operator Workspace

The dashboard supports repeat work: create a job, follow progress, inspect output, and resume from a known state.

## Result

The media manager keeps source files, clips, thumbnails, metadata, and drafts together. The operator sees what is ready, what failed, and what needs review without extra system noise.
