Hi I am new to these forums so I hope you guys can help me. I have recently switched to a LCD TV for my computer display (Vizio 26"} from a 19" CRT. When I play back XVids on this display they are badly pixilated or posterized. Is there a way to filter them to make for correct play back. They never appeared this way before on my CRT monitor. I noticed that some files using the x264 codec seem to play back ok. System Specs in case they help: p4 2.8ghz EVGA 7800gs co Superclock 3 gigs of pc3200 Turtle beach Montego
I am running 1360 x 768 at 60 hz which should convert over to 720p. I have done some research and believe that it may be to poor quantization on the videos. I read some where that LCDs have trouble displaying this. I however don't exactly know what quantization is or if I can correct this. Any in site would be greatly appreciated.
Why don't you spin off a 10 or 20 second clip and let somebody take a look. (post it to a file hosting site and put the URL in here) In general, any quality loss due to too low a bitrate cannot be recovered. Unless, of course, you have the original source - in which case you can do a fresh encode.
Well one thing to note is that dedicated PC monitors are different than TVs. Your old 19" CRT probably had a resolution of 1600 x 1200. A 24" PC monitor has 1920x1080 resolution.
My CRT monitor was capable of 1600x1200 where the 26" LCD is capable of 1360x768. I think the xvids are encoded with an old version of the xvid codec using low motion which may account for the varying quality of some vids.
