@tymektt try getting hold of "handbrake" video compression software. free and works a treat. all our videos are compressed on there.
to be honest, i've struggled to see a difference
takes a bit to get it exactly like you want it, but simple enough!
our 30-35 minute videos compress down from around 1.5 gb to around 400-500mb........no loss of quality that I can personally detect!
