# Can someone give me a good definition of "Blend Decimation"

1. I don't know exactly what that is in words or how it works. I just know how to use a filter related to it but dont 100% fully understand how it works.

tdecimate(mode=1, hybrid=1)

Ive read all about tdecimate on many different pages, but it keeps saying "Blend Decimation" alot and I wish to understand it a bit more.
2. Decimation means reducing the number of frames.

Suppose you have 3 frames [A][B][C] and you want to decimate it to 2 frames. Here is a possible way:

[A+B][B+C]

The first frame, for example is a blend of frames A and B. That is blend decimation.
3. Two frames blended together (with equal weighting) to make one frame:

Code:
`(frame1 + frame2) / 2`
Or in AviSynth, N frames reduced to N/2 frames:

Code:
`Merge(SelectEven(), SelectOdd())`
