I would like to crop the corners of my video to use the green screen effect. However, my green screen isn't straight at the corners. Unfortunately, the crop feature in Camtasia 9 does not do this>>>is...is there a way to draw a line mask like ohter software like like after effect?
Let's say your green screen looks a bit like this.
Take some rectangular callouts.Size, Rotate and Position them over areas you need masked out. Use the color picker to make them match your green screen as close as possible.Make the duration of the callouts long enough to cover the entire video.If can apply animations to move them if need be.
Render the video as an AVI. TechSmiths screen codec 2 is a high quality codec that is well suited for this purpose.The default setting is great.
No need to render the audio yet. I would just wait until final production for that. Then just bring in the AVI and apply remove a color to that. It's a little extra work, but if you don't have access to anything else.It should work out for you.
