=== SelectEven/SelectOdd ===

{{Template:Func2Def|SelectEven(clip ''clip'')|SelectOdd(clip ''clip'')}}

SelectEven makes an output video stream using only the even-numbered frames from the input. SelectOdd is its odd counterpart.

Since frames are numbered starting from zero, SelectEven actually selects the first, third, fifth,... frames by human counting conventions.

=== SelectEvery ===

{{Template:FuncDef|SelectEvery(clip ''clip'', int ''step-size'', int ''offset1'' [, int ''offset2'', ...])}}

SelectEvery is a generalization of filters like SelectEven and [[Pulldown]]. The easiest way to describe it is by example:

SelectEvery(clip, 2, 0) # identical to SelectEven(clip)
SelectEvery(clip, 2, 1) # identical to SelectOdd(clip)
SelectEvery(clip, 10, 3, 6, 7) # select frames 3, 6, 7, 13, 16, 17, 23, 26, 27, ... from source clip
SelectEvery(clip, 9, 0) # select frames 0, 9, 18, 27, ... from source clip

And how about this:

# Take a 24fps progressive input clip and apply 3:2 pulldown,
# yielding a 30fps interlaced output clip
AssumeFrameBased()
SeparateFields()
SelectEvery(8, 0,1, 2,3,2, 5,4, 7,6,7)
Weave()

=== SelectRangeEvery ===

{{Template:FuncDef|SelectRangeEvery(clip ''clip'' [, int ''every''] [, int ''length''] [, int ''offset''] [, bool ''audio''])}}

This filter is available starting from v2.5. The filter selects ''length'' number of frames ''every'' n frames, starting from frame ''offset''. Default values are: Select 50 frames every 1500 frames, starting with first selection at frame 0. (''every'' = 1500, ''length'' = 50, ''offset'' = 0).

Starting from v2.55, SelectRangeEvery will also process audio. To keep the original audio, use ''audio = false''.

'''Examples:'''

# Selects the frames 0 to 13, 280 to 293, 560 to 573, etc.
SelectRangeEvery(clip, 280, 14)

# Selects the frames 2 to 15, 282 to 295, 562 to 575, etc.
SelectRangeEvery(clip, 280, 14, 2)
