# Video Processing

Working with video files and exporting processed video.

## Short Summary

This page covers how to load videos, apply effects frame-by-frame, control playback, and export processed video.

## Loading Video

1. Drag and drop a video file onto the viewport, or Use the top menu to browse and select a video file.

Supported formats: MP4, MOV, WEBM, and other common video formats.

## Playback Controls

The video playback controls appear when a video is loaded:

- Play/Pause: Start or stop video playback.
- Timeline Scrubber: Click or drag to jump to specific frames.
- Playback Rate: Adjust playback speed.
- Loop: Enable/disable video looping.
- Mute: Toggle audio on/off.

## Applying Effects to Video

All algorithms can be applied to video:

- Select an algorithm from the Mode dropdown.
- The effect processes each frame in real time during playback.
- Adjust parameters while the video plays to see changes immediately.

## Video-Specific Algorithms

### Blob Track

- Tracks moving regions in the video.
- Displays blob IDs and tracking information overlaid on the video.
- Useful for motion analysis.

### YOLO Track

- Real-time object detection using the YOLO model.
- Detects and labels objects (people, cars, animals, etc.).
- Displays bounding boxes and confidence scores.
- Detection runs every few frames for performance.

## Exporting Video

1. Click Export in the top bar.
2. The Video Export Settings panel opens.
3. Choose export options:
   - Codec: H.264 (MP4), Lossless (MOV), Animated GIF, or PNG Sequence.
   - Quality: For H.264, choose High, Medium, or Standard.
   - Filename and output path.
4. Click Export to begin rendering.

### Export notes

- The entire video duration is exported with effects applied.
- Rendering may take time depending on video length and effect complexity.
- A progress bar shows export status.

## Performance Tips

- For complex effects, playback may not be real-time; this is normal.
- Pause playback when adjusting settings to see the effect on a single frame.
- Lower video resolution before exporting for faster processing if needed.
