ok somebody explain why its worth watching a 720p video on a 800x480 screen?
lets look at what is actually going on here.
first off one is larger than the other:
screen size: 800x480 (384,000 visible pixels)
video size : 1280x720 (921,600 visible pixels)
difference: your actually only seeing a little more then a third of the actual detail. you "lose" 537,600 pixels of detail.
hears a visual example of what you are losing.http://img22.imageshack.us/i/resopoint.png/
the point i am trying to make is that there are allot of people on this forum that are complaining about their 720p videos playing really choppy. the underlying problem is actually the bitrates of most of these videos. someone said somewere that the bitrate cap is somewhere around 4000Kbits/s. allot of people think they are running 720p videos at "under" 4000K. there is an extremely good chance that this is not true.
you see most modern methods of encoding video (and even audio) employ variable bitrates. this means that during slow scenes the bitrates are kept low, and during high motion fast scenes the bitrate spikes way up to compensate. this means that the bitrate will go higher then the requested bitrate.
so its possible that the videos that mos people are running are either encoded at a bitrate that is too high, or their video is using variable bit rates.
the fix i am recommending is to either:
a) lower the resolution of the video during the encoding proccess to something that will fit on the screen normally and lower the bitrate to match. (this option makes the most sense to me)
b) in the situation that you intend use the player to watch your 720 videos via the video out, lower the bit rate to less then 4000k. if your preferred codec does in fact use a variable bitrate then see if the encoding program will allow you to adjust the max bitrate to something lower than 4000k.
either option should fix the issue.
also, i would suggest that everyone use a variable bitrate codec if they can. it will reduce the size of you video files considerably without losing the quality. if any of you have questions about how to encode a video in either a) or b), post it here or email me at:
with a little research into video encoding, anybody should be able to enjoy good quality video on their mp4 players.
