even being an easy question for some people i couldn´t find anything on the net. the question is the next: will my 4:3 conversion (divx to dvd with tmpgenc) work on a 16:9 television without being centered? cause i have a 4:3 tv but im going to buy one 16:9 someday. the second: how can i see the quality of an divx dvdrip by the bitrate? cause i´ve seen ones with less bitrate and more quality. will they have a very bad quality in a 16:9 tv?
4:3 content is either displayed in the centre with black bars, stretched or zoomed. For instance a lot of old stuff is encoded widescreen, but 4:3 so on a 16:9 you have to zoom or else you have black bars on all four sides. Problem is that the zoom never looks that good. If the content is actually 4:3 then if you zoom, you miss out on the top and bottom of the image. Bitrate and quality can be quite seperate. It depends a lot on the source. For instance I could start off with a crap quality source and encoe with a high bitrate. So basically you can't tell the quality by bitrate. Also there is the number of pixels. For instance 1280x720 @ 1Mb probably isn't going to look too special. So bits/pixel would be more accurate.
so if i burn a divx to dvd in 4:3 it can be 16:9 on a 16:9 tv? depending on the divx source information? or depending the tv? or i have to zoom it to make it 16:9? isn´t there a way to make dvd like the dvd9 movies, i mean that support both systems(4:3/16:9)?
If you have a wide screen TV, then you don't want 4:3 if your source is wide screen. But yes as I said, it is possible to zoom on the WS tv, but that never looks as good as a proper anamorphic DVD. Sure you can author two versions of the film, one 4:3 and one 16:9. No point unless the 4:3 version is fullscreen though.
