You can load files using file_text_read, but how does the file look like? For an example I made it like so:
Clip1, 2, 27, 20,
Home movie, 3, 5, 30,
Intro, 1, 0, 5,
Long background clip, 6, 25, 70,
This is a comma separated file that is very easy to load. The first one is the name, then channel number, then start time and then length.
I added a basic example on loading and drawing those clips as an attachment. Download both and put at the same folder.
