You could cut the video down in parts. Half of 1.5gb is exactly 750mb. I'm guessing there's a chance that you don't end up with exactly 750 each though (unless 1.5gb was a slight round up), so you could remove a few seconds or just do 3 parts and that would work.
Edit: Just noticed you posted it with fileditchfile you're the goat! Thanks for sharing. Is there some time stamps where you'd consider the being best moments of the live?
