Loading Large Video Files into MadMapper: A Detailed Guide
MadMapper is a powerful tool for video mapping and real-time video processing. Whether you are a professional VJ or a hobbyist, you might find yourself needing to load large video files into MadMapper for various projects. This guide will walk you through the process, covering everything from file preparation to optimization and troubleshooting.
Understanding Video File Formats
Before you can load a video file into MadMapper, it’s important to understand the different video formats and their implications. Common video formats include:
| Format | Description |
|---|---|

| FLV | Flash Video format, commonly used for streaming on the web. |
Each format has its own advantages and disadvantages. For instance, MP4 files are great for streaming due to their efficient compression, while MOV files offer high-quality video with a larger file size.
Preparation of Video Files
Once you’ve chosen the appropriate video format, it’s time to prepare your files for loading into MadMapper. Here are some key steps to follow:
