Video Characteristics.

well, in this task, i had to open a video(it was pre-chosen) and upload it into movie maker

then, i had to save it as all these different video types and compare the differences in a table.

these are my results: (sorry it's so small, i couldn't do it any bigger without it going all pixel-y :S)

then, i had to save the video as two different file types. the first one was "Video for dial up access (38kbps)" and the second one was "Video for IDSN (48kbps)"

then i had to watch both copies of the video and compare them.

when i watched the first one, it was all pixel-y and i couldn't really make anybody out. All the picture was fuzzy, and the colour was bad too. Everything was a dark green-y colour. nothing like the original. Also the sound wasn't very clear.



when i watched the second copy is was perfect. The picture was very clear, and so was the sound. the colour was good aswell. it was just like watching the original.

now, i have to give possible reasons for these results. okay, so first i went to movie maker and opened the video, then i chose to save it as the first one (again) but i didn't save it, i just looked at the information (the cream boxes in the table above.) and it said there there were only 15 frames per second, which can contibute to the pixle-yness of the video and the colour aswell.

then i chose to save it as the second one again, and the frames per second were exactly the same, so i have absolutly no idea why thing one it better than the other except that maybe the first one is for a dial-up and we don't have dial-up on these computers.

other than that i have no idea,
anybody got any ideas ?
