Review detections¶
After a run finishes, choose Review detections in the completion dialog, or use File → Review results folder… and pick a directory that contains annotations.csv (and a resolvable source video via megadetector_results.json or parameters.csv).
The review window shows the source video, a timeline scrubber, and a table of rows from annotations.csv. Bounding boxes on the video match the filtered table: change filters to focus on a class or confidence range.
Layout¶
- Splitter — Drag the vertical bar between the video and the table to resize.
- Label — Restrict rows (and overlays) to one label, or All.
- Min score — Hide rows below this confidence (0.0–1.0). Missing scores are treated as 0.0.
Mouse¶
- Scrub the slider to move through the video.
- Click a table row to jump to that frame.
- Prev detection / Next detection — Jump to the previous or next frame that has at least one row in the current filtered table. Navigation wraps (e.g. from the last detection back to the first).
Keyboard¶
| Key | Action |
|---|---|
| ← → | Previous / next frame |
| Home | First frame |
| End | Last frame |
| Space | Start or stop playback (approx. video FPS, capped at 60 FPS) |
Playback stops when you scrub the slider, use arrow keys, jump to a detection, or reach the last frame.
Files¶
- Open result folder opens the run directory in the system file manager (CSV, optional JSON, optional
detection_frames/JPEGs).
If the source video path is missing or the file moved, the review window cannot open the player; keep outputs next to the original video or ensure parameters.csv lists the correct source_video path.
