Getting good SimulCam Fixed results

Here are some tips for getting good SimulCam fixed results.


Remember to film the background!

In order to extract the performer from its background, you should have at least one frame of video showing the background but WITHOUT the performer present. This can be done in two ways:

1.	Record a separate clip of the background before you start to film the action.

2.	The background shot may be the first few frames of video before the performer enters the field of view.

Fixed means fixed!

The camera cannot move or zoom during filming and it can't move or zoom between filming the background and filming the performer. Using a tripod is therefore essential.

If comparing performers at the same location on different occasions it will help comparison if you use the same position and zoom each time. Mark the position and take note of the zoom used.
