What is this grey line?

Alright It's time I figure out what's going on. Almost every video I make has this weird grey line on the very bottom of the frame, sometimes it breaks up and the pieces move around, sometimes it's just a solid line and every once and a while it disappears for a few seconds. Here's an example (Watch it in full screen or you won't notice it):




This is my workflow, I'm shooting with a 60d.

- Conform footage to prores422 with MPEG Streamclip
- Import into Final Cut Pro 7
- Cut
- Color Correct
- Apply 2.35:1 or 1.85:1 matte and adjust footage to compose in the best way possible
- Color Grade
- Send to Compressor
- Compress using one of the internet streaming compression presets I've created.

Now somewhere in between the time it's in final cut and the time that it comes out of compressor that line appears. It's distracting and I need to find out how to stop it. Does anyone have any ideas? Places you recommend I seek help?

Thanks,

just found this on vimeo forums

"Ok, on a cropped 2.50:1 movie for example my movie is 2048x818 when you scale that down to reach 1280 ( per Vimeo's recommended settings) the scale factor is 1.6 but that leaves you with 1280x511.25 and what I discovered is that with encoding you cannot round down, you must round up.
So in the end I had to do 1280x512 that was the ticket to get rid of the weird 1 pixel grey encoding line."

so try cropping out one extra px line at the bottom i guess?

not sure if that helps or not

I'm going to go ahead and say Crotch's solution will work fine.

But I think if you had purposefully added a pixel line to the top, it might've actually done something more for the video. I tried to picture what it would look like and it'd essentially frame the video, which in this type of storyline and plot format it'd be sick!
