Great vids with crackin soundtracks,and a very nice section of coast you've shown us there. didn't know there where mines around the coast like that, very interesting.
I know what you mean taking ages to upload, I have the same problem and I was told it's down to the size cable they use to supply broadband, they've renewed most cables around the major cities, to cope with higher demands, but the further out towns and villages have older cables with less broadband width to carry and send.
After editing my vids I sometimes save as email size, then uploading is much quicker, but quality suffers dramatically.
