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, by human counting conventions SelectEven actually selects the first, third, fifth, etc, frames.
SelectEvery(clip clip, int step-size, int offset1 [, int offset2, ...])
A generalization of filters like SelectEven and Pulldown. The easiest way to describe it is by example:
And how about this:
SelectRangeEvery(clip clip [, int every] [, int length] [, int offset] [, bool audio])
Selects length number of frames every n frames, starting from frame offset.
int every = 1500
int length = 50
int offset = 0
bool audio = true
By default, select 50 frames every 1500 frames, starting with frame 0.
SelectRangeEvery will normally process audio. To keep the original audio, use audio=false.
