Quick Start Guide — VirtualDub

This guide is for Neat Video v4 plug-in for VirtualDub being used with VirtualDub 1.9.11.

If you use another Neat Video plug-in or another editing application, please select the corresponding quick start guide.

1. Installing the plug-in

To install the Neat Video plug-in for VirtualDub
  1. Make sure you have started VirtualDub at least once before installing the plug-in. If you have not done that yet, start VirtualDub and exit it.
  2. Download the installer of Neat Video for VirtualDub:
  • If you already purchased the product and have a current license for the Home or Pro plug-in, please download the corresponding Home or Pro plug-in from My Products page
  • If you want to try Neat Video before purchase, please download the Demo plug-in from Download page
  1. Double-click the downloaded EXE file to start the installer.
  1. Proceed through the steps of the installation process.
    When you install Neat Video, Setup asks you to specify VirtualDub’s ∖plugins∖ subfolder to install the plug-in there.
  2. Start VirtualDub and find Neat Video in the list of filters: Video > Filters… > Add… > Neat Video v4 .

In case the plug-in was not installed into the right folder, you still can manually install it into VirtualDub using the guidelines below.

To manually install Neat Video plug-in into VirtualDub
  1. Copy the NeatVideo4.vdf file from the Neat Video installation folder
    (typically, C:∖Program Files∖Neat Video for VirtualDub∖) into the ∖plugins∖ subfolder inside the VirtualDub folder.

    Typically, the NeatVideo4.vfd file should be copied to:
    C:∖Program Files∖VirtualDub∖plugins∖
  2. If you install the 64-bit version of Neat Video, please make sure you specify the plugins folder (or plugins64 in newer versions of VirtualDub) of the 64-bit version of VirtualDub.

    For the 32-bit Neat Video specify the plugins folder (or plugins32 in newer versions of VirtualDub) of the 32-bit version of VirtualDub.
  3. Then start VirtualDub and find Neat Video in the list of filters: Video > Filters... > Add... > Neat Video v4.
In case the plug-in has not become available in VirtualDub, please contact Neat Video support for assistance.

2. Running Neat Video on a sample video clip

Please download the test-kit prepared to help you start using Neat Video. Having downloaded, please unzip it to a new folder on the hard disk.

The test-kit includes a sample video clip: SampleClip.mp4. This is a typical video clip captured by a digital video camera in high-gain mode. Some technical information about the sample clip is available in the SampleClipInfo.txt file.

Please start VirtualDub and go through the steps below to clean the clip using Neat Video.

2.1. Open the sample clip

1. Configure a new project in VirtualDub

Use the File > Open Video file … menu in VirtualDub to open the SampleClip.mpg file:

The VirtualDub preview window will display the sample clip and you will see that there is strong noise in it. The task of Neat Video is to reduce this noise.

2.2. Add Neat Video to the composition

  1. Use the Video > Filters... menu item to open the list of used filters:


  1. Click the Add... button to open the list of available filters:


  1. Select the Neat Video v4 filter in the list and click the OK button:

VirtualDub will add the Neat Video filter and will open the frame selection window.

2.3. Configure Neat Video

1. Open Neat Video plug-in window
  1. Click the Build Noise Profile button to open the main Neat Video plug-in window.
    (If you run the Demo plug-in, click Ok in the popup splash screen of the plug-in to proceed further).

The Neat Video plug-in window will open and display the current frame from the clip.


Select Progressive in the popup dialog (if Neat Video asks to specify the scan type) or in the lower left corner of the main Neat Video plug-in window.


2. Build a noise profile for the clip

To reduce noise in this frame and in the whole clip, Neat Video generally needs a noise profile describing the noise properties of the clip. You can prepare such a profile using the Auto Profile function:

  1. In the Device Noise Profile tab       click   

Neat Video will then automatically analyze the noise to build a new noise profile:

  1. Visually inspect the selected area — it should contain no visible details, only noise; otherwise the noise profile and subsequent noise reduction may be inaccurate.

If the selected area does contain any details, move the selection to a featureless area or simply draw a new selection in such an area (the selection must be at least 32x32 pixels large). Then click the Auto Profile button again.

After that Neat Video is ready to filter the clip.


3. Check Preview
  • Switch to the Noise Filter Settings tab 

You will notice that Neat Video has already applied noise reduction based on the default filter settings and the preview shows a clearly visible difference: there is less noise than in the original frame.

You can try to adjust the filter settings and see how that affects the results. For example, try to adjust the Temporal Filter > Radius setting (in the Temporal tab in the Filter Settings box in the right part of the window) from 2 to 1 or to a higher value. This will apply weaker or stronger temporal noise reduction to the frame.


4. Apply the changes
  • Click    in the bottom of the plug-in window.

Neat Video will save the current settings and close its main window.
(If you run the Demo plug-in, it will also describe the limitations of the Demo version at this point).

Once this step is completed and Neat Video window is closed, the filter is ready for work.

The preview in VirtualDub now shows the clip with noise reduction applied to it:


2.4. Render the video

To apply Neat Video noise reduction
  • Use the File > Save as AVI... menu item in VirtualDub and proceed to render the clip.

This will automatically apply Neat Video noise reduction to the sample clip and save the result to a new video file on the hard drive. You will then be able to open this new file, evaluate the filtration results and adjust the filter settings if necessary.

Please see the User Guide for more details about adjusting the filter settings and other aspects of using Neat Video. These Video Tutorials will also help you to get the most out of Neat Video noise reduction.
