Script to automate time code-based videos

[cryptopinion]

Hey,

I am using Avidemux on Mac El Capitan.

I am trying to create thousands of one-minute clips from a long initial source video. I want to start at time = 0 in the long initial source video, and render a one minute clip. Then, move to time = 5 seconds and render another one minute clip. Then, move to time = 10 seconds... and so on until the entire long video is done.

I've been trying to work out a script to make this happen, but no luck. Any ideas?
