The MSU Frame Rate Conversion (FRC) Filter for VirtualDub is a video processing plugin designed to make video playback smoother by increasing the frame rate through motion-compensated interpolation. Developed by the MSU Graphics & Media Lab, it generates entirely new intermediate frames based on the motion vectors between existing frames.
Depending on your specific definition of “smoother,” the laboratory also offers separate specialized tools like the MSU Deshaker (for camera stabilization) and the MSU Deinterlacer (to remove interlaced motion artifacts). Core Capabilities of MSU FRC
Integer Frame Rate Up-Conversion: The filter multiplies your frame rate by whole numbers (e.g., converting a cinematic 15 fps or 24 fps video up to a smoother 30 fps or 60 fps).
Motion Estimation: Instead of simply duplicating frames (which causes stutter) or blending them (which causes ghosting), it analyzes pixel movement to accurately guess what the missing motion looks like.
Quality Preservation: It preserves original frame clarity while adding visual fluidity. How to Use the MSU Filter in VirtualDub
To process your video and make it smoother, follow these sequential steps:
Install the Plugin: Download the filter file (usually .vdf) from the official MSU Graphics & Media Lab Filter Page and extract it directly into the plugins folder inside your VirtualDub directory.
Open Your Video: Launch VirtualDub, click File > Open video file…, and select your target video clip.
Add the Filter: Navigate to Video > Filters… from the top menu, click Add, select the MSU filter from the list, and click OK.
Configure the Parameters: Adjust the settings in the filter’s dialogue box to set your desired frame rate multiplier (e.g., 2x up-conversion).
Set Processing Mode: Go back to the Video menu and ensure that Full processing mode is checked.
Choose Compression: Click Video > Compression…, select an appropriate video codec (such as Xvid or an MP4 variant), and configure its target quality.
Save the Smoother Video: Go to File > Save as AVI… to render out your newly smoothed video file. Alternative “Smoothing” Filters by MSU
