Prosya Banding Fix

The Banding Fix effect fixes banding due to limited 8-bit color or highly compressed sources.

You can download the Win or Mac trial version as well as a sample project to test it out. The watermark will be removed once you pay and enter the activation code. The trial is full-featured except for the watermark.

This effect works with 16-bpc and 32-bpc color. The optimal usage will require 16-bit or 32-bpc and full resolution. In 32-bpc color, After Effects does not clip the video and allows the user to view any out-of-range data. In 8-bit mode, the effect cannot operate and you will not see any changes in output.

The filter detects regions that have banding and smooths the transition between the colors. Remember that film has infinite color gradation and will never show pixelization. The Banding Fix filter tries to mimic this property. To understand the effect, use the AE Levels filter to check the histogram before and after applying the Banding Fix filter.

Before applying the effect, a frame with banding will show discrete steps.

After the filter is applied, the gaps are “filled in”.

And the result with the filter on the top half of the frame, the bottom half is the unmodified image.

The controls allow you to switch between RGB, HSL, YIQ and YUV colorspace. This effect can also be used to fix the banding show in Red and Blue colors due to YUV 4:2:0 compression.

Channel – Switch between RGB, HSL, YIQ and YUV colorspace. Default is RGB.

Layer Blend Ratio – Define the amount of effect you wish to use. At 100% the entire effect is active, and none at 0%. Default is 100%.

View Colorspace – The allows you to view the intermediate colorspace before it is converted to RGB for display. This is only useful for HSL, YIQ and YUV colorspace. Default is off.

Horizontal-Vertical Blend – The filter fixes the banding in horizontal and vertical direction in discrete steps and blends it together. You may choose non-default values for creative effects. Default is 50%.

The 3 sections indicate the 3 channels for the colorspace in use. For RGB, these are Red, Green and Blue. For HSL – Hue, Sat and Lightness. For YIQ – Luma, I-Chrominance and Q-Chrominance. For YUV – Luma, U-Chrominance and V-Chrominance.

Detection Limit – The minimum change in color to detect banding. The value is a percentage of the total color range i.e. 0-255 for 8-bit. Default is 20%

Detection threshold – Banding is indicated when a block of pixels is followed by another block with a certain change across their boundary. This value indicates minimum block size. Default is 4.

Horizontal Smoothing – Once banding is detected the edges are smoothed out to mimic the film color gradation. This value is the maximum number of pixels across horizontal block boundaries that should be used for smoothing.

Vertical Smoothing – Once banding is detected the edges are smoothed out to mimic the film color gradation. This value is the maximum number of pixels across horizontal block boundaries that should be used for smoothing.

ProSya Scopes

The Scopes effect provides multiple waveforms, histograms and vectorscopes in a minimalist design as overlays for monitoring and editing.

You can download the Win or Mac trial version as well as a sample project to test it out. The watermark will be removed once you pay and enter the activation code. The trial is full-featured except for the watermark.

This effect works with 8-bpc, 16-bpc, and 32-bpc color. The optimal usage will require 32-bpc and full resolution. In 32-bpc color, AE does not clip the video allow the user to view any out-of-range data.

The dropdown choices available include

  • Red, Green, Blue and RGB Histograms
  • Red, Green, Blue, RGB and YUV Waveforms
  • YUV and YPbPr Vectorscopes

The image is divided into 4 regions – Top Left, Bottom Left, Top Right and Bottom Right. In each region, you can place any of these scopes.

Guides – This checkbox can turn on or off the minimalist guides.

Size – This sets the size of the scope as a percentage of the output image.

Opacity – At 0%, it disables all the guides and places only the scopes over the output image. At 100% you see the guides and scopes on a black background. The other values give you different degrees of opacity.

Brightness – Histograms and waveforms use pixel intensity to indicate the number of times that color value is used as compared to the max value. Brightness sets the pedestal of that color value. This is useful in cases where you wish to see the lesser used values clearly.

Trial Watermark

Guide to Plugin Activation

When you first use the software you will find a Trial watermark.

The plugin controls will show Trial License at the bottom. Click on Details.

In the popup window, select Obtain Serial.

You will be asked to choose between Basic and Advanced activation.

Typically, if you want to use a floating license, you can click on advanced activation. Lets deal with basic activation first. Click on Basic. The activation program will link to the first valid MAC address. A serial will be generated. Please write this down somewhere. The window will now close.

Now you can browse to www.prosya.com and follow the payment and activation procedure. Once you have the activation code, you can, once again, click on Details near Trial License.

In the popup window, select Activate Software.

In the popup window, enter the activation code you received after payment.

When you select OK you will be shown the license. The license is also available on the website. Read through the license and shut the window when you are satisfied. Now you will receive the confirmation.

Now restart After Effects. You will find that the plugin controls display that the license is activated.

And you will find that the watermark is no longer rendered.

ProSya software licensing model

I wanted a licensing model that would ensure protection of my work, as well as a comfortable experience for customers. So, each software is licensed to 2 MAC addresses.

Every Ethernet, Wifi and Bluetooth adapter in your system has a unique MAC address.

You can buy a cheap USB Wifi, Ethernet or Bluetooth adapter for a convenient floating license. Just plug it into any supported device and your license is valid. For convenience, you can install the software on one device using the fixed MAC address, and you can use the other license with a USB adapter so you can use the license on other supported devices. The 2 licenses can be used over any device, for any combination of fixed and/or floating licenses.
