# Introduction

# Video Transformations

Transform your videos on-the-fly using our powerful transformation system. This guide explains how to use transformations to resize, crop, add effects, and optimize your videos.

## URL Format

Transformations are applied by adding them to the URL:

```
https://cdn.apexxcloud.com/f/{access_id}/{transformations}/path
```

For example:

```
https://cdn.apexxcloud.com/f/abc123/tr-w_1280,h_720/videos/sample.mp4
```

## Basic Format

Transformations follow a simple, consistent pattern:

```
tr-{parameter_name}_{value}
```

### Combining Transformations

Multiple parameters can be combined using commas:

```
tr-w_1280,h_720
```

Multiple transformation sets can be chained using plus signs:

```
tr-w_1280,h_720+blur_10
```

## Transformation Categories

Our video transformation system is organized into six main categories:

1. **[Resize](/transformations/video/resize)** - Control video dimensions and scaling
2. **[Crop](/transformations/video/crop)** - Smart cropping and focal point control
3. **[Effects](/transformations/video/effects)** - Visual effects and filters
4. **[Overlays](/transformations/video/overlays)** - Add text, image, and video overlays
5. **[Format](/transformations/video/format)** - Format conversion and optimization
6. **[Thumbnails](/transformations/video/thumbnails)** - Generate video thumbnails
