I recently upgraded to Vegas 13. I also purchased a Panasonic HC-X920M full HD camera. With the camera set to 1920x1080/50P I am getting poor quality playback loading files onto timeline of Vegas 13. Problems like: Mosquito like artifacts, jagged vertical lines during panning and jittery playback. These are particularly noticeable on the TV monitor.
I also have a working version of Vegas 8 version C. When the above files are played back with this, there are no quality problems like in Vegas 13. What can be causing this and why should there be such a difference between Vegas 8 and Vegas 13?
