I am using Camtasia 8- My screen recording is approx 30 minutes long. I have done in multiple sections- but recorded video and audio together- when i play it back the audio jumps as if the narrator is 'rapping' but this does not happen in same place all the time. How do i know what ' blips' to fix? as well, i am in the middle of editing- i have added all sections on timeline- and i find the more i edit - add transitions- call outs etc- it appears i get more ' blips' am i degrading the screen recording the more editing i am doing? Is there someway to keep the integrity of the original recordings but still edit?
