I want to shoot a dance video with a green screen as the background, and I want to edit it later. What size suits me best?

The size of the green screen depends on the size and shooting distance of the video you shot. Generally speaking, the size of the green screen should be at least as large as the screen size of the video to avoid the green edge or sawtooth effect when keying later.

If you plan to shoot full HD video (1080p), it is recommended to buy a green curtain at least 1.8m high and 1.2m wide. For higher resolution video (such as 4K or 8K), a larger green screen is needed to ensure better keying effect in the later stage.

In addition, buy green curtains should pay attention to the following points:

1. Choose high-quality green curtains to reduce flicker and reflection.

2. Make sure that the color of the green screen is even, so as to avoid the color difference in the later keying.

3. When buying, ask the merchant if there is any packaging. I also want to ask, what problems should be paid attention to when shooting, so as to capture images better later?
