Using Replay Video Capture at default settings... I set my markers to fill the computer screen and play the video I wish to record. Everything works wonderfully (and Thank you!!) but it really sucks up a lot of GB! One hour long video is 2GB. I recorded a series of videos and it's a whopping 100 Gb's. Can I lower this someway - it has basically taken up the remaining space on my external drive! Many thanks in advance!
