How to use the average tab

Second movie

Click "Choose" to open the movie that is to be averaged with the input movie.
The second movie must start at the same point and the frames must correspond to those of the input movie by number.
The second movie may be shorter or longer.

Shift

Two recordings of the same TV show or VCR tape may differ by a slight horizontal shift.
JVC can correct this shift, even if it is a fractional number of pixels.
The shift can be estimated automatically.

Weight

The weight determines how much of movie 1 is used.
If movie 2 is noisier than movie 1 use a value like 0.6 (=60%).
Automatic estimation of weight is less accurate than shift.
