Here’s a very nice ouchi gari (or as wrestler’s call it: inside trip) from Victoria Anthony (USA) against Anzhela Dorogan (AZE) in the 48 kg division in the Heydar Aliev FILA Golden Grand Prix in November 2013.
The interesting thing to notice here is that the trip is done on the overhook side. This is how I’ve seen it mostly done in high-level wrestling. That’s different from how it’s done in judo where it’s done on the “underhook” side. Of course, in judo, it’s usually a lapel grip and not an underhook but those are actually similar in terms of how the throw is performed.
Here’s one of many instructionals on this basic takedown from a wrestling perspective:
