Why does my key have green edges?

Almost always spill: green light bouncing off the screen onto the subject, particularly on shoulders and hair. Move the subject further from the screen, reduce the light on the screen to only what is needed, and add a backlight from a neutral colour to separate the subject. Spill suppression in software helps but cannot rescue heavy spill.

How evenly does the screen need to be lit?

Evenly enough that the keyer sees one colour rather than several. A common target is within about a stop across the area, checked with false colour or a spot meter. Perfect evenness is not required, but a hot patch in the middle and dark corners will produce edges that will not key cleanly.

Green is the usual choice for video because sensors carry more green information and green is further from most skin tones. Blue is better when the subject wears green, has green hair or props, or when you want less spill on blonde hair. If your presenter's wardrobe is unknown, green with a wardrobe note is the safer default.

Do I need a green screen at all?

Often not. A real background at a distance, thrown out of focus, looks better than a mediocre key and takes no post work. Green screen earns its place when the background must be replaced with something specific. If you just want a clean look, a plain wall and a bit of separation light is easier and more convincing.

Collapsible vs Fabric Green Screen (2026)

Short answer

A collapsible screen is stretched over a frame so it has no wrinkles, which is the single biggest cause of a bad key. Fabric on a stand is far larger and far cheaper, but only keys well if you get it flat and light it evenly. For a seated single presenter, the collapsible screen gives a better key with less work. For anything full length or more than one person, fabric is the only affordable way to cover the area.

Choose the RAUBAY Collapsible Green Screen Backdrop if…

You shoot a seated presenter, you set up and pack down often, or you work in a space where a backdrop stand cannot stay up. A tensioned screen unfolds in seconds and is flat by construction, which removes the wrinkle shadows that most keying problems come from.

You still have to light it. A green screen needs its own light, reasonably even across the area, and the subject needs to be far enough forward that green does not spill onto their shoulders and hair. Two soft sources aimed across the screen from each side, with the subject a few feet in front, is the standard arrangement and it matters more than which screen you bought.

Choose the Green Screen Backdrop 10x12ft Muslin if…

You need to see feet, you shoot more than one person, or the budget is the constraint. Fabric is by far the cheapest way to cover a large area, and a 10 by 12 foot backdrop on a stand handles full length shots that no collapsible disc can.

Flatness is your job. Steam or iron the fabric, or hang it under enough tension to pull the creases out, and give it time to settle after unpacking. A wrinkle casts a soft shadow, the shadow is a different shade of green, and the keyer treats different shades as different things. Most complaints about cheap green screens are actually complaints about wrinkles.
