The .MTS footage from the Canon Vixia HF M300 is not importing well into Adobe Premiere Pro CS6. Basically, it imports without any audio. I tried downloading 6 different converter programs and the closest I got to being able to use the footage was converting it and then getting a super pixelated tripped up version. One conversion program let me convert it fine and when I played it back on Quicktime there was no noise in the image--no trip-ups, but then when I imported it to Adobe, it got messy and the image would tweak out. I even tried rendering one of the imported clips thinking it was a problem of the computer speed, but that didn't do anything to clean the image up. How do I rememdy the situation?
