This method is the latest and greatest method from Tom Barry. This new method improves on some of the older methods in two important ways.
- Where there is motion, the bob pixels are generated by looking along a series of diagonals as well as simple the ones above and below.
- Also when there motion the code will try and spot slowly moving objects and will try and maintain the detail on those objects.
The combined effect of these two searches is a big jump in picture quality and also a big jump in CPU usage.
Who Should Use It?
Everybody with a fast machine. 1 GHz is about the minimum required to use this method.
The Settings
There are only two options to set for this method:
- Search Effort: This setting will control how much CPU is used by the method by controlling how big an area the method will search looking for matches. A Search effort (SE) of 0 means that all pixels are smart bobbed and is not recommended. SE = 1 does no motion compensation, but doesn benefit from the diagonal bob interpolation. SE > 1 starts to do true MoComp with increasing CPU demands. You should use the highest value that allows you to run any other filters etc withuot dropped frames.
- Use Strange Bob: This was some test code added by John Adcock to try and reduce the number of errors in the diagonal searches. It is not recommended.
