In a couple of clips along the bottom edge of the layer I can see red and white stripes like a warning bar. I cant search for the problem because I dont know what it is called and I either get results about the beer or the band.
Please let me know because it's killing me :)
A world of difference when you post a screen grab and give us the Premiere import bit of info- I would've thought you're seeing compression artifacts at the bottom of your clip in the preview window. This makes it clear and easy to answer: the clip has been reversed in Premiere, that's why it has the stripes at the bottom.
