Hi there! I'm trying to make my first video and the source files are crisp and clear, but when sony vegas displays them in the preview there is occasional juddering and distortion. I'm not sure what the correct term for it would be, but it shows up when rendered too.
I've tried increasing the bit rate to maximum, tried different encoders, tried disabling resampling of the clips, made sure all the framerate settings match what it was recorded in. I've fiddled about with deinterlacing methods, too. Nothing seems to work.
