The after-effects option is an integral part of every video creator software. Use the Spill Suppressor Effect Within After Effects This is unlike the hard color replacement method, where the alpha channel is increased to add the required amount of replacement color in the image. Here, Keylight modulates the pixel’s luminance to match the original by adding the required amount of color into the image. The soft color replacement method is crucial because it’s an efficient way to remove the green spill. You can also switch your view to see which pixels Keylight is modifying. It can be added and removed whenever the alpha is altered. You can also stick to the source method, where the original screen color will be what the pixels try to match. Although, it may be a tricky color replacement or a soft color replacement. Keylight has a method that intelligently blends the pixels that are similar to the screen color. Apart from Bias Controls, another way to remove green spills is by changing the way you handle pixels. Keylight is an excellent tool for video correction and post-production. Change the Way the Keylight Handles Pixels on Video But before you can do that, you need to uncheck the ‘Lock Bias Together’ option. However, on some occasions, when it’s more about the tone of the background compared to the foreground, this option can be used to fix the issue. There’s no need to change the Alpha Bias. Usually, the Despill Bias and Alpha Bias are linked together. To remove it, simply select a natural skin tone from the image and apply it where you want the green to be removed. Let’s say you have an image where the green color is persistent in the background, or some of it has spilled over onto your image. Doing this ensures a good color key is achieved. There’s an option where you can lock both. The Controls include Despill Bias and Alpha Bias. In Keylight, one of the best ways to get the desired result is by locking the Bias Controls together. Check out my suggestions for which video lights to purchase at the end of this article. Avoid creating more susceptible dark areas on subjects by using excessive lighting.Īn excessive use of backlighting is one of the easier and more effective ways to avoid green screen spill.Use floppy flags placed outside the frame on either side of the screen.Increase the distance between subject and screen so that the light from the green screen doesn’t fall on the subject.Use spiked green tubes to light green screens effectively.Try using tungsten lamps because they help to distribute light on a green screen from both sides evenly.Use a light meter to measure the amount of light on the screen and verify that the readings match the iris of the camera lens.Ensure the light is neither too dim nor too bright.Of course, if you’d rather do things yourself, here are a few tips to keep in mind: Experts also help avoid green spills by correctly moving and placing the camera in a position that doesn’t disturb the lighting and aggravate the green spill. You could always consider hiring a VFX supervisor or marker to assist in camera movement to consistently capture adequate lighting. Resolving the green spill problem requires a proper and elaborate understanding of the lighting techniques. Almost always, a clean video can be obtained without any green spills if the shoot is done behind a green screen under natural light. Most of the green spills happen due to improper lighting conditions in your studio.

You can still see flickering at edges and green microborders. Logitech Capture's live chroma key gives better results than both ChromaCam and Vcam but is nowhere near as good as Zoom. I won't be paying for Vcam, which costs even more for the same garbage. Super disappointing, especially since I paid for ChromaCam. The result is that they struggle with green trails, disappearing body parts, etc. There are no weird light green microborders or edge flickering using it, and video was smooth.ĬhromeCam and Vcam seem to lack any direct green screen support, opting to simply brute force the problem instead. Zoom seems to be the only app of the group capable of proper edge detection with the green screen setting enabled. I recently picked up an Arozzi Green Screen and tested background replacement using it with Zoom, Personify ChromaCam, Logitech Capture, Cisco Webex, and XSplit Vcam.
