Banding can be produced by (starting with most common causes):
- inaccurate video compression by host application;
- inaccurate decompression by player software (QuickTime on Mac is especially bad at that);
- inaccurate processing by host application itself;
- limited precision of the data representation used;
- other causes.
What is banding problem in video processing?
These areas are often affected by the banding problem, which shows up after the original noise is removed from the clip by a noise filter and then compressed by a lossy video codec. The example frames below have been taken from different points of a typical processing workflow to illustrate the problem and possible solitions. 1.
What is color banding?
What is color banding? Color banding, or posterization is an ugly artifact that can be seen in digital images. It’s most often visible in a gradient between two similar colors. Banding refers to the visible change from one color to another instead of a smooth, fading gradient.
How to fix 8-bit banding in video?
As a last resort, you can create an Adjustment Layer and drop the Noise filter on top. Switch off color noise and add 1% noise as a final retouch. This workflow should eliminate the nasty banding artifacts from your 8-bit footage entirely, or at least make them far less visible and annoying.
How to avoid the problem of banding?
The problem of banding can be avoided using different approaches. One of them is to keep some of the original noise in the output clip. The presence of noise prevents the output codec from introducing the banding.
What causes banding in videos?
One of the most common causes of banding in video is lossy codecs used to compress video. Therefore, minimizing the compression ratio when exporting video will reduce or eliminate the stepping within the image.
What is film banding?
Banding film's elastic memory means it can stretch significantly from its original length. The film tries to return to its original shape and form after wrapping, resulting in a tight, secure wrap. This process ensures bundles will not come undone or need to be rewrapped during transport.
What is banding in editing?
Color banding is what happens when the bit depth is too low to support enough shades of a color to allow a smooth transition. The name is quite literal because when it happens a series of lines, rings or bands appear, separating shades or tones instead of showing a smooth gradient.
What is banding on a screen?
Banding, also called false contouring or posterization, refers to unrealistic solid strips of color in areas that should display a smooth transition.
What is banding in cinematography?
Colour banding is a subtle form of posterization in digital images, caused by the color of each pixel being rounded to the nearest of the digital color levels. While posterization is often done for artistic effect, colour banding is an undesired artifact.
What causes banding?
Banding happens when there aren't enough tones available to recreate a seamless gradation; that's why they're most common in 8-bit image files and with image files that have been heavily compressed. In each case, there are less colors available with which to work. Working in 16-bit mode allows for more colors.

What is banding in camera?
A camera setting that prevents the appearance of vertical or horizontal lines (banding) when photographing images on TV and monitor screens. Antibanding may be automatic or have manual settings for 50 Hz and 60 Hz to ensure the frame rate is the same as the country's electrical grid. See banding.

What is HDR color banding?
Posterization, also called solarization or color banding, is characterized by a loss of image quality on color gradients. Instead of being smooth and progressive, they appear in the form of successive patches or bands with clearly defined shades.
Common causes
One of the most common causes of banding in video is lossy codecs used to compress video. Therefore, minimizing the compression ratio when exporting video will reduce or eliminate the stepping within the image.
Three different points where Banding can be spotted
You can encounter banding at various stages of the video editing process:
Example
To demonstrate how banding can be introduced into your video, we’re going to apply a series of techniques to the same piece of footage, experimenting with full and partial noise reduction with both intermediate and final codecs (in this case ProRes 422 and H.264 main profile) to see what delivers better results.
Reduce banding
Adding some noise to a picture is very efficient way of making banding less noticeable. There are several different ways of adding noise to your video. In some video editing applications you can use built in effects, while others don’t have such a feature. Adding an overlay with noise works in most apps.

What can be done to reduce color banding?
So, we already know that color banding is happening due to bit depth reduction and monitor bit depth. Let’s address the first issue with the image.
Common Causes
- Lossy codecs
One of the most common causes of banding in video is lossy codecs used to compress video. Therefore, minimizing the compression ratio when exporting video will reduce or eliminate the stepping within the image. - Removing Noise that Masks Banding
It is important to note that noise removal does not create banding but can reveal banding if already present in an image. Noise can often mask pre-existing banding and therefore in using a noise reduction filter or effects such as Gaussian Blur, this banding will be unmasked and revea…
