Motion Blur Tool

Executive Summary: a simple tool for creating motion blurred images and videos from videos.

Motion Blur Tool creates a motion-blurred image from an input movie. The ideal input movie has been rendered at a very high framerate.

To Use simply load the movie (two examples are provided) pick a position in the movie, and then click "Motion Blur".

Frame Rate: allows you to set the framerate of the output movie (new!)
Save Movie...: allows you to render a motion-blurred movie
Sample Frames: determines the number of frames that will be sampled
Shutter Speed: the duration the "shutter" will be open
Mode: the "anchoring" of the sample frames
- Centered: sampling will be centered on the current frame
- Trailing: sampling will end with the current frame
- Leading: sampling will start with the current frame
Bias: the method used to weight frames
- None: all frames are equally weighted
- Cosine: frames are weighted via cosine functon
- Quadratic: frames are weighted via quadratic function
Quality: preview simply renders the frames on top of each other which introduces a lot of rounding errors; high quality renders each pixel component into a 64-bit buffer, and then outputs the final result (i.e. fewer rounding errors)
Save Image: outputs a PNG
