Unlike optical flow tools that require manual point tracking, RSMB analyzes the entire frame. It generates motion vectors for every pixel, allowing you to add blur that perfectly matches the physical world.
If you are working with 3D software (Cinema 4D, Maya, Blender), you can render a "Motion Vector Pass." This pass tells the plugin exactly how every pixel is moving.
We ran a torture test: A drone shot flying over trees (complex parallax) slowed down to 25%.
| Feature | After Effects' Pixel Motion Blur | RSMB Pro 6.2.1 | | :--- | :--- | :--- | | Render Time (10 sec clip) | 4 minutes | 7 minutes | | Edge Artifacts | Heavy "boiling" on leaves | Minimal; slight softness only | | Foreground/Background | Fails frequently | Uses vector masking to separate | | GPU Utilization | Partial (Metal/CUDA) | Full CUDA & Metal support in 6.2.1 | revisionfx reelsmart motion blur pro 621 plug
The Verdict: RSMB is slower, but correct. In VFX, you trade speed for accuracy.
To ensure you get the best results every time:
First, a quick reality check. RSMB is not a "smoother" (like Optical Flow for frame rate conversion). It is a vector-driven motion blur synthesizer. Unlike optical flow tools that require manual point
The "Pro" version analyzes the movement of pixels between frames. It creates motion vectors—essentially a map of where every pixel is going. Then, it adds synthetic blur back into the frames based on that velocity.
Why build 6.2.1 matters: This specific release focuses on stability for Adobe After Effects (Multi-Frame Rendering) , DaVinci Resolve (Studio) , and Foundry Nuke. It also fixes a critical bug where motion vectors would occasionally "tear" on high-contrast edges.
