I've been trying to work out why exporting some noisy low light footage in premiere pro CS6 is giving me 'diagonal rain' problems that aren't present in the original m2ts files from my GH2.

Reading two similar topics (below) the problem seems to be related to GOP length, which hack is being used, and the decoding abilities of certain players. But I shot this footage with the original firmware so this can't apply? Possibly it is a CS6 specific issue?

It's not footage I can take again so any advice on how to export this without the noise would be amazing... I'm a beginner but not posted it there as the problem seems to be a complicated one.

I just uploaded the start of my edit to youtube for an example of the problem. Some of my footage was 24p and some was 50 fps 720p but the problem persists in all the export formats I've tried;

1080/50 p footage edited

Output to 1080/25p Mp4 h264 codec 10000 mbps

Upload to YouTube

I have read on the YouTube site that you should keep your footage frame rate and your output the same but I thought that conflicted with other information I read that said you should output to Mp4 for best results ( cant have 50p with Mp4)

I thought I would ask here if there was anyone with similar experience here and any helpful tips. I did look at other topics but this question was not specifically addressed.

iv seen some nice quality exports on here... anyone have any advice? thanks
