![]() They isn't likely any noticeable difference between the two depending on how it's displayed.
They are the same resolution. The file size differences are a result of the codec used. Why not download both and test for yourself? |

![]() Ultimately you'll have to download both versions and compare - but I would think that the first file would be better quality as it has a higher bitrate of 2048kbs vs. 1600kbs for the smaller.
A lot will depend on what you are using to view it - a crappy 7 year old monitor like mine or a proper HD TV. Having said that, I would comment that even the first file doesn't really have true HD specs - 2048kbs is a very low bitrate for HD. A lot of sites claim to be offering HD when they aren't at all because of the low bitrate encoding. Just consider that a Blu-ray disc (which is true HD) - has a max bitrate of 40Mbps (1Mbps=1024kbs). That will give you some idea of just how much quality has been squeezed out of those "HD" clips you have. 720p and 1080p don't stand for much when the clips have had the shit kicked out of them by lowering the bitrate. ![]() |

![]() but I heard somewhere (don't know if correct) that bitrate is just theoretical issue. because for human eye, you won't see a difference bettween higher and lower

You are likely confusing bitrate and framerate. framerate would only apply for like gaming. bitrate is the amount of data in the image. If you have a shot glass of beer and a pitcher of beer, could you tell the difference? |

![]() I have never worked with HD but for standard DVD or TV rips I think a bitrate between
2500-3000 is the best. You don't really see any difference above that. 500 looks like old youtube clips. |
