The High Density Recording or HDR filtering feature of the RDI's motion amplification software platform is a feature that help user to get following benefit.
Showing motion at a specific frequency.
Eliminating noise and distortion.
Eliminating environmental vibration.
Nice and clean amplified video.
This filtering process is considered similar to the Synchronous Waveform filtering (1X, 2X, 3X, etc.) in the traditional vibration measurement world. It shows vibration at only wanted frequency.
The process to get the HDR filtered video is showing in the following video.
In the next topic, I will show you how to use HDR filtering to overcome the noise, which is generated from air diffusion/distortion on the high temperature objects. This is the noise that very difficult to remove.
