Yesterday I recorded a speedrun video of an online game, and I used Camtasia 8 to edit it. When I sped up the video to about 125% the video started to lag. So I went with 120% and everything was fine. I was almost done with the video, but it was late so I thought that I'll just finish it tomorrow. When I started up my laptop today and opened up my edit all my gameplay was laggy! I checked the speed of the clips and all of them were 120%. I don't know what to do :( Please help fast.
