AlignedSplice (clip1, clip2 [, ...])UnAlignedSplice (clip1, clip2 [, ...])
AlignedSplice and UnalignedSplicejoin two or more video clips end to end. The difference between the filters lies in the way they treat the sound track. UnalignedSplicesimply concatenates the sound tracks without regard to synchronization with the video. AlignedSplicecuts off the first sound track or inserts silence as necessary to ensure that the second sound track remains synchronized with the video.
You should use UnalignedSplicewhen the soundtracks being joined were originally contiguous - for example, when you're joining files captured with AVI_IO. Slight timing errors may lead to glitches in the sound if you use AlignedSplicein these situations.
Avisynth's scripting language provides + and ++ operators as synonyms for UnalignedSpliceand AlignedSplicerespectively.

# or: AVISource("cap1.avi") + AVISource("cap2.avi") + AVISource("cap3.avi")
# Extract three scenes from a clip and join them together in a new order
