Loop

Loop(clip clip [, int times = -1] [, int start_frame = 0] [, int end_frame = inf])

Loops the segment from start_frame to end_frame a given number of times. Setting times to -1 loops a "very large" number of times.

Examples:

# Loops frame 100 to 110 of the current clip 10 times:
Loop(10,100,110)

Loop()         # make the clip loop (almost) endlessly
Loop(10)       # make the clip loop ten times
Loop(10,20,29) # repeat frames 20 to 29 ten times before going on, actual clip duration increased by 90 frames
Loop(0,20,29)  # delete frames 20 to 29, actual clip duration decreased by 10 frames
Loop(-1,20,29) # frame 20 to 29 is repeated (almost) infinite times
