AviSynth to VapourSynth code translation

is there a better, possibly shorter way to achieve SelectEven and SelectOdd?

Code:

Select Even 

	fpsnum = clip.fps_num
	fpsden = clip.fps_den
	clip = core.std.SelectEvery(clip = clip, cycle = 2, offsets = 0)
	clip = core.std.AssumeFPS(clip = clip, fpsnum = fpsnum, fpsden = fpsden * 2)

Select Odd

	fpsnum = clip.fps_num
	fpsden = clip.fps_den
	clip = core.std.SelectEvery(clip = clip, cycle = 2, offsets = 1)
	clip = core.std.AssumeFPS(clip = clip, fpsnum = fpsnum, fpsden = fpsden * 2)

From the docs:

Code:

# Select even numbered frames
ret = clip[::2]
# Select odd numbered frames
ret = clip[1::2]

works

Also, SelectEvery will adjust the frame rate and frame durations for you.

Yes, somehow I missed it and made it much more complicated than it is.
