Ohaiyoo1 and Ohaiyoo 2-Video Characteristics

I've learnt that when you upload a video to the internet there are a few things that you need to consider:
-Frame rate

-Colour depth

-Resolution
b).So, I saved the two different 'short videos' as Video for dial up access (38kbps) who's nickname is ohaiyoo1 and Video for IDSN (48kbps) who's nickname is ohaiyoo2. I found that the difference was that ohaiyoo2 was a lot more clearer and the pixels were not very visible to the human eye, the resolution was higher . In Ohaiyoo1 the resolution was very low which made the whole video seem shaky. The colour depth; the number of bits that represent colour in each pixel was not very distinguished which made the overall colour very grey and blended together as a result of the resolution. The video was also very jittery and jumpy because frame rate was very low compared to ohaiyoo2. Ohaiyoo2 the number of bits per pixel or colour depth was very high and gave a broader range of distinct colours. It is a lot more clear for the viewers and the particular movements of the people in the video were a lot more smooth compared to ohaiyoo1.

c). I think that ohaiyoo2 is the better quality from the differences above and because it is faster by the amount of data that can flow in a given time as it is 48kbps and ohaiyoo1 is 38kbps.(kbps=kilobits per second-thousands of bits per second) It is also better quality as it has a higher resolution, colour depth and frame rate.
