Maybe it's doing something else, because it has to up-scale nearly all sources. I still must check all formats on my new FullHD-TV.

if DAR is correct, the recommended 12/11 and 16/11 SAR for x264 is wrong 720x576 DV-AVIs are Rec.601, with coded PAL-SAR. 704x576 and 720x576 are treated with the same sample-aspect-ratio (SAR), not DAR, so they're scaled by the same factor, not to the same destination size. My PAL-TV (tube) doesn't do this: DVB-streams via RGB are stretched to ~1047x576 (hardware-MPEG2-decoder on DVB-card) I just notice, that the MPEG2-specs talk about a display-aspect-ratio (DAR) in the sequence-header, so a 720x576-16:9 MPEG should be scaled to 1024x576.

Indeed 1024x576 is 1.78:1 (=16:9), but the MPEG is coded with non-square pixels and it's questionable how to decode that back to square-pixels.

So when the DVD authoring/mastering guys manufacture a DVD according to the specs, and the DVD makers do the same for their products, then the combination should work - this is how a standard works.

It's the responsability of both software and hardware manufacturers to ensure the compatibility of their products with the specs. WHY?īecause 1024x576 is 1.78:1, you have quadratic pixels on your PC.įor what I know, they don't test it on software players, but they run the result through certain 'conformity checkers' (like Eclipse), it's the mastering facilities that test the test DVDs against a series of SAP DVD players (it's just optional, an extra convenience, as long as eg Eclipse said OK it should be OK). To my understanding the DVD should be played at 1047x576, or perhaps 1050x576, but all four software-players scale to 1024x576. I just recognized, that mplayer, VLC, MediaPlayerClassic-HC and also WMP 12 still scale my DVD-VOBs wrong on my PC-screen. I understand, that some companies are too lazy to change something.īut even open-source players with active development should have recognized, that their players don't scale as the hardware-players do.

Adobe says 12/11 (1,091) is the right PAR: Link () (before, they had 16/15)Īll guides I find recommend 12/11 or 16/11, and hardware-players do use that aspect-ratio anyway. SAR 16/11 is also recommended for encoding with x264 I can't believe the movie-makers just check with software-players and don't check if it looks correctly on TV (for what a DVD is actually created). So, it's just the software-players, what do it wrong. its more like no one cares about those specs.īut all my checked hardware-players do scale to about 1047x576:
