Ok, Just wanted to let you all know I figured this out. Looking at the codec I realized that this was old motion jpeg codec somehow upgraded to do 4K. Weird but it’s actually MPEG2 and very similar to the old Matrox Board .avi formats. Having said that I fired up my old Windowx XP Pro Machine with Sorensen #9 on it and imported it and converted it to HD 1080p and Bingo I can now Edit this in Vegas Pro 15! Hope this helps some of you guys out!
Murph.
