FONDO DE COLOR

Hi @ursula32909205lr2k,

It sounds like you need a white background. You need to create a "synthetic" clip called a Color Matte.

1. Select the Project panel.
2. Chooose File > New > Color Matte
3. Choose the size and click OK.
4. Choose a white color from the Color Picker and click OK.
5. The color matte is now in the Project panel.
6. Edit the color matte to the timeline.
7. Place scaled down images on V2 so you can see the white background.

I hope that helps you create what you are hoping to. Let us know if it does not help.

Thanks,
Kevin
