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?
