I've been going through some of my old shows I filmed with my cybershot camera which were filmed in mp4 format and am getting some strange artifacts when I load them into Pinnacle 16. The artifacts only seem to happen with the older mp4 files while the newer shows I filmed in mts format show no issues what soever.

Attached below is a picture of the white blocky pixelation that predominately happens in the lower right portion of the screen. It lasts for a second or 2 and happens in random parts of the files. When I open this mp4 files in other programs the artifacts are not present in any form so it has to be a Pinnacle issue. Also, the artifacts appear both in the preview window along with the finished product.

If anyone out there has any ideas as to what might be causing this I would be eternally grateful for your input.

Thanks!
