GoPro HD footage. 720p 60fps
Premiere Pro Cs4
Importing with AVCHD 720p 24fps
Exporting with H.264 codec and HDTV 720p 23.97 fps (with square pixels)
I'm using a quad core 3.3 ghz AMD athlon 2 processor with 4 gb of ram and an BFG 8800 gtOC graphics card
I have exported multiple times and this happens no matter what. I have tried eliminating clips that it occurs on, removing effects, changing export settings, etc. but nothing works.
I have also found that it happens in different spots in the video.
HELP ME!!!
