Hi everyone,
I used quicktime X to screen record a skype video chat and im trying to crop it so that theres just the skype window and not my desktop. I used imovie and did this but the video quality is terrible when i export it (shadows are like flcikers of grays). Im wondering if theres a way to do this to keep te exact video quality ( when importing to imovie i clicked keep original quality but still turned out terrible after i exported it) or to simply crop the video i need out of the movie. thanks!

What kind of file did you save from QTX, and what export settings/presets are you using? Depending on your codecs and settings, you can sometimes re-encode video quite a few times before there is much of a quality hit. You want to save your screen recording as something easily editable, like ProRes.

umm the original videos are all saved as .mov and for imovie i create a new project and then import video file (clicked keep original quality even though theres an error flag saying the playback quality might be bad...dont know why this is) and then i crop it, it looks great in the preview window of imovie. then i go export-> movie and after its done it looks crappy. Im sorry if that doenst make sense iv never done anything video related with my mac.
