Grainy/pixilated video when uploading to youtube.

I hope this is the right place for this, apologies if it's not.

I've searched around on google to try and find a solution but I can't really find anything with the same problem. Basically, when I upload videos to youtube they get a grainy pixelated thing happening at random points like this;

I've tried re-uploading and it happens again, but at different points and it seems to happen on every video I've uploaded over about the past year, I trued uploaded stuff from discs and my digital camera so in different formats and that makes no difference. I've also tried uploading through both youtube itself and through Movie Maker and I leave the computer running with just the upload open so that's the only thing it's doing but again it has no effect.

I presume it would be to do with my connection, but my connection is alright any other time. Plus I haven't actually seen it on any other video I've watched so it doesn't seem to be a very common problem? Does anyone know how to solve it or why it might be happening? It's getting really annoying now.

Don't know what causes it but it definitely won't be your connection

Sounds like your computer is not up to encoding videos very well. Have you tried it on another computer?

Encoding runs the same on any PC, but just slower. The output isn't different if it has the same settings and source.

Unless the file is corrupt.

Yeah, I've tried it on 3 different laptops and the main computer and they all do it.

It seems to be when it gets uploaded that it ruins the video because it plays fine on my computers. Also, if I re-upload it, it will do it again but in a different place.

I'm trying to think when it actually started to happen, I remember uploading some performance from Proms in the Park last year and that's when I fist noticed it but as far as I'm aware there had been no changes. I had the same laptop at that time as I'd used before and I had recorded it and got it on my computer the same way as normal.

Would it be possible to try one of the laptops or computer on another internet connection, that way you can rule out if it is the computer or connection?
