JAV Headed Backwards?

[Casshern2]

“You're hiding something out there … and it's going to send us back to the Stone Age!"

No doubt you recognize that from the Godzilla trailer. You should! If you haven't seen it, do check it out.

Fitting I should use Godzilla, the destroyer of Tokyo, for my intro, because I've seen some JAV destroyers in the DDL section. Are we to believe in this day and age (I've always wanted to say that) that we are headed backwards in terms of aspect ratio of JAV media? Really?



I apologize for the extra click, but I did this in a hurry. That screenshot image is from a recent post and the video dimensions are touted as being 640x480. Really. I can safely tell you that any and all Madonna releases as of late (way late) are in fact 16:9 releases and not 4:3 as these screens portray. No, I'm afraid these are probably rush jobs to be released into the wild, but why wouldn't they do it right?

And I will say that I haven't downloaded any of these. Not that I would, but has anyone? Are they in fact presented incorrectly within your player as 640x480. Yuck. Only Godzilla would abide by that.

This tends to happen from time to time.

There have been ton of realses with weird aspect ratios.

This is due to only one thing and that being the one who encoded to take out the DRM or ripped from DVD is an amateur.

The person who has been releasing an influx of that aspect ration probably wont keep doing it for long.

My advise is to track the guy whose posting these and see if hes the one who is encoding them or ripping them or see where he is getting them from to advice on his aspect ratio.

Relax dudes, the screen caps clearly shows that the full 16:9 frame are all there. Note the humans in the frame are all squished sideways, no they are not that slim.

The encoder was a little remissed but it's nowhere fatal. Most players (XBMC, VLC etc) are just a couple clicks away from restoring the 16:9 ratio. If the vid grabs your fancy, download one of these 640x480 file and try it out. At best your player will notice it and play it as 16:9. More likely it won't then you have to change the playback aspect ratio, like I said, a few clicks on most players.

Remember the agogo-tv thread? All the vids from that site are 16:9 screen ratio vids with 4:3 pixel ratio, no worries.

Wouldn't you be losing scan lines if encoding to 4:3 and then having software stretch to artificially present as 16:9? I think it would. But it just doesn't matter I suppose.

Short answer is "not necessarily". It's somewhat an historic factor, on CRT tv (and therefore VCR tapes, and even DVD) the y-direction is fixed to so many lines, depending on NTSC vs. PAL, but the X-direction is analog and it's free to the player (or TV) to stretch to any desired (or undesired) aspect ratio.

So it's entirely possible that the original media was 16:9 display ratio, but 4:3 in pixel ratio. So it's even possible that these 640x480 files are the most faithful encoding available. For many early DVD, it's common, I believe.
