Rendering the video

## Introduction

This dialog has two different appearances depending on whether you clicked a button for device type or the Advanced button.
If you clicked the device type button, the dialog has two selection zones:

- The first zone allows you to select a device category
- The second zone allows you to select a device model

If you clicked on the Advanced button, the following dialog will appear:

## Description of the dialog box in advanced mode

## Render the movie

Once the you have selected the device or set the advanced parameters, one click on the OK button starts the process of rendering the video.
At any time during this process, one click on the "Cancel" button stops the process.

### Remark :

Depending on the device model or the advanced parameters which you selected, the generation can take quite a long time.
Generally, for a Full-HD 1080p video :

- On a PC with 4 fast cores (Core i7 for example) : The process will take approximately 2 minutes for each minute of video to be rendered
- On a PC with 2 cores (Core 2 duo for example) : The process will take approximately 5 minutes for each minute of video to be rendered

This amounts to 2 to 5 hours for a one-hour video.
This duration will be much shorter for a video in VGA resolution. That is why we recommend you to carry out all tests and focusing trials at low resolution, and to render your videos in Full-HD only for the last step.
