Speed ramping (slow-mo) is trendy. But standard frame blending looks like garbage. Optical Flow looks like "liquid plastic." RSMB 6.2.1 introduces a new "Shutter Angle Override" for retimed clips. You can tell the plugin: "This clip was shot at 1/48th shutter, but I slowed it down to 10%. Simulate a 360-degree shutter." The result? Buttery smooth slow-mo without the "soap opera effect."
The "Pro" version includes everything in the standard version but adds crucial controls for professional compositing and VFX work:
1. Motion Vector Import/Export (The Key Pro Feature)
2. GPU Acceleration (OpenCL/CUDA)
3. Object Separation
4. Distance and Depth Support
Let’s walk through a real-world scenario where RSMB Pro 621 shines. You have a 3D render of a spaceship flying across a starfield. Your render engine (Octane/Redshift) rendered it without motion blur to save render time.
Step 1: Import the EXR sequence into After Effects. Step 2: Apply RSMB Pro 621 to the layer. Step 3: Analysis. Click the "Analyze" button. For a 300-frame 4K sequence, this takes roughly 45 seconds on an M2 Ultra. Step 4: Settings.
Result: Your CGI render now swings past the camera with creamy, realistic motion blur, exactly as if it were captured at 1/48th second shutter speed.
