Slow Shutter Mode
Neat Video includes a dedicated Slow Shutter mode allowing the filter to adjust its work to this special condition — presence of repeated frames in video data — and to apply the noise reduction correctly to all frames. Please check this article for more information.
This tutorial explains the problem of repeated frames, its influence upon noise reduction and the solution offered by Neat Video — the Slow Shutter mode. Two examples of actual use of that mode are included. The first example demonstrates the use of this feature with proper repeated frames in a clip with artificially increased frame rate. The second example demonstrates another clip with repeating noise that also required special treatment provided in the Slow Shutter mode.
The tutorial uses Neat Video in After Effects, but all the points are exactly the same in other versions of Neat Video (for other host applications such as Premiere, Final Cut Pro, Fusion, Nuke, Sony Vegas, Pinnacle Studio, VirtualDub and others).
The tutorial is available in higher resolution. You can switch the player to the full screen and increase the resolution up to 1080p.
