Upscaling h.264 1440x1080 files / correcting the AR
Hi,
my PS3 seems to have problems playing back 1440x1080 h264 files (muxed in m2ts stream together with an ac3) in the correct aspect ratio. I tried nearly EVERY option in h264info to get the right AR. Setting the AR to 16:9 brings pixelating, setting the resolution to 1920x1080 bring an unplayable files. All possible combinations between those options and 4.1/5.1 etc. do not work either. I could simply set the PS3 to "Display Fullscreen", but I do not want to because I am a bit too perfectionistic So, coming to the point: What is the best way to scale 1440x1080 up to 1920x1080? The files are already deinterlaced. Is there any good filter for VDMod out? I prefer VDMod as I am used to it for a long time. Can the scaling quality of a good filter be compared to the scaling quality of a PC/PS3 or whatever? I would imagine that scaling up with VDMod is way better as it takes many hours for a process that the PS3 has to do "on-the-fly". Am I right with this? Thank you very much, Oli |

You don't need to scale, you just need to add borders. If you don't have to use vdub and can use avisynth instead, just do:
DirectShowSource("yourfile") AddBorders(240,0,240,0) Vdub might have a similar filter, I don't know much about that though. At any rate, this sort of stuff is more along the AviSynth subforum, you should check it out it's a treasure trove of information (but don't cross post this topic there, mods will move this if they see fit)

You need to signal a PAR (=SAR) of 4:3 or alternatively a DAR of 16:9. I'm not familiar with h264info, so judging from a screenshot: Setting »output aspect ratio« to »16:9« should be correct. Does the pixelating only happen on the PS3 or on the PC as well?
@lexor 1440x1080 files are usually anamorphic. Just adding borders very likely results in a distorted picture with »egg heads«. And you'd have to re-encode as well.

Ah, since he mentioned vdub filters, I thought he wanted to re-encode. This is also the first time I hear about anamorphic 1440x1080, the ones I've ever encountered were actually 4:3 picture for HD.

Hi,
yes, they are anamorphic... Setting the AR to 16:9 in h264info brings pixelating on both PS3 and PC. I tried lanczos4 for resizing with avisynth, feeding the avs in VDub and encoding again. Encoding is running, I will tell you about the results! |

For example: 1440 x 1.3333 = 1920 Cheers

But how should I get the PS3 to understand this other than by reencoding? I think that the pixelating comes from the PS3 trying to upscale the 4:3 picture to 16:9. lanczos4 should do a better job than the build-in upscaler of the PS3, doesn't it?

Lanczos is probably "better" than what the PS3 uses, but re-encoding will kill things by comparison.
Try remuxing, and setting the AR there. Hopefully the PS3 will understand and stop meddling! ~Misfit
