External Matte

A separate file that provides an alpha channel or mask for compositing or effects work.

What is an external matte in DaVinci Resolve?

An external matte in DaVinci Resolve refers to a grayscale image or clip that is used to control where an effect or correction is applied in a video. It is essentially a mask that allows you to selectively apply effects to certain areas of your video. The matte works by using the grayscale values to determine the transparency of the effect. The darker areas of the matte will have less of the effect applied, while the lighter areas will have more of the effect applied.

This feature is particularly useful in post-production when you want to isolate and manipulate specific parts of your footage without affecting the rest of the image. For instance, you can use an external matte to change the color of a specific object in a scene, add a special effect to a certain area, or correct a particular part of the footage. It provides a high level of control and precision, making it a valuable tool for video editors and colorists.

How to use external matte in DaVinci Resolve?

To use an external matte in DaVinci Resolve, you first need to import the matte into your project. You can do this by going to the "Media" tab and then navigating to the location of your matte on your computer. Once you've found the matte, you can drag and drop it into your media pool.

After importing the matte, go to the "Edit" tab and drag the matte onto a video track above your footage. Then, go to the "Color" tab and select the node of the footage you want to apply the matte to. Right-click on the node and select "Add Alpha Output". Connect the blue square on the node to the blue circle on the output. Then, right-click on the node again and select "Add Matte" > "Timeline Mattes" and select your imported matte. This will apply the matte to your footage.

Why is my external matte not working in DaVinci Resolve?

There could be several reasons why your external matte is not working in DaVinci Resolve. One common issue could be related to the file format of your matte. DaVinci Resolve supports a variety of file formats, but not all. Make sure your matte is in a format that DaVinci Resolve can read.

Another possible issue could be related to how you're importing or using the matte within the software. If you're not correctly linking the matte to your footage, it may not appear as expected. Make sure you're following the correct steps to import and use your matte. If you're still having trouble, it could be a software glitch. Try restarting the software or updating to the latest version. If none of these solutions work, consider reaching out to DaVinci Resolve's customer support for further assistance.
