What is this phenomenon?
I mostly happens when I'm using a MTS file (AVCHD, 25.000 fps interlaced, 1920x1080x12, AVC) and rendering to MPG2 for DVD. I'm using Sony Vegas 10 but I'm pretty sure it's a cross platform problem.
The project matches that of the original file, it improves when it's 'Progressive Scan' and selecting 'deinterlace' doesn't help. Rendering is generally a 'high quality' bit rate of 9mil, 2 passes etc... If I render to the equivalent in MP4 this phenomenon doesn't occur but will then reoccur when converting it to MPG2 and let's face it the less file converting the better. The att is a particularly good bad example.
So what is it? If I knew I could google it and do something about it. Thanks in advance for any help!
