Tried it and no change. Even though 26 of my 32Gb of RAM is dedicated to Premiere, it still bogs down with the .mts files. Still bogs down if I dedicate the max (29Gb).
I also noticed that the files are choppy when I play them outside of Premiere. I updated my video card driver, but it is still jerky.
After researching this online, I am seeing many, many people with the same problem and NO solution. This is strange considering the popularity of both Panasonic and Sony.
Any ideas?
