A simple question:

I have an (*.avi) XviD 1.1.0 with a broken aspect ratio of (720x432).
I have to force aspect ratio to (720x314) so it can display as it should be.
Now I've tried this app. in several ways but the output is always the same as the input (720x432).

1. Is this normal ? can Mpeg-4 Mod. do what I need it to do?
2. Is there a way to do this except re-encode ?

Thx

All you could do is change the Pixel Aspect ratio to alter the Display aspect ratio to get it closer to what you want. You cannot change the resolution without re-encoding and you can only alter the horizontal resolution by stretching the pixels to correct it.

Try entering 992 and 432 in the Custom Display aspect ratio boxes. That should stretch the picture and should make the Aspect ratio look correct if played on your PC. It will not look correct on a TV.

I've all ready tried that but nothing... I even tried to change it to 4:3, just to see what happens -nothing still the same output (as the input).

It seems I'll have to re-encode it after all
I'll try out a few more things... and hopefully avisynth will help out with the quality loss.

Thx for the replay

EDIT: there is a way to correct an avi like that (wrong aspect ratio) with Quicktime pro but you'll have to save it as a (*.mov) and it doesn't work with all the avi files.

gatekeeper_007,

What media player are you using. Maybe it is not set-up correctly?


Cheers

I really don't think so... but then again who knows,

Same result with : WMP11, NeroShowTime, DivxPro6, VLC... and others.
and of course I passed it in a flashUSB -pluged it to a divx/xvid player (widescreen TV output) same aspect ratio problem.

Thx

EDIT: In Nero I have to force it to 16/7, In divx 720x314(320) or 640X272 so that can be correct

Try adding "64:45" in the "Custom" boxes. And don't forget to select the "Custom" radio button: -

nothing...

is there something wrong with the avi's bitstream..? because it seems it won't change to anything else.
I think that I wont be able to avoid the re-encode after all.

anyway...
thx for your help!!

- WMP11, Divxplayer..., Divx/XviD standalone - display's wrong aspect ratio
- NeroShowtime and VLC will display it with the correct

EDIT: same happens with my avi, only Nero/VLC will display it correct after the change.
EDIT 2: same result if I set the Display AR to 2.35:1, and if I set Pixel AR 64:45
I mean 2.35:1 -output will be playable but again only with nero and vlc

Play the sample file again with WMP11. Then click on: File -> Properties and find out which Video Codec you're using.

Personally speaking, I would not recommend using WMP11 to play any type of media file. It's too limited.

-I don't

It seems that this app does work, but the 'new' stored info can only be read by certain pc players.
But the thing is that I don't really care much about how it display's on the pc, after all I don't mind to force the aspect ratio via the player so I can watch it.

I was just wondering if I can overwrite the AR info in avi's bitstream permanently so it will display ok on a standalone and I can avoid more quality loss by (re-encode) but if not it's ok -not that big deal.

What stand-alone player are you using... Not all of them are clever enough to understand AR signalling embeded within the MPEG-4 video stream.

I have 3 but only use 1

LG DNX190H
KiSS DP 508
Silvercrest KH6515/16 HDMI

It may sound funny but the one I mostly use is the Silvercrest, not because of the HDMI (if u ask me HDMI is almost useless is the player doesn't support HD playback).

I can't test it on the Kiss (because is somewhere in the boxes with my old staff, after all it can't read packed bitstreams), but the other two won't display it as I want it to.

Your KiSS player (with Sigma chip-set) is more likely to automatically recognise AR signalling.

The firmware in your Silvercrest player (I have a similar Tevion player) can't automatically detect AR signalling. Neither can most other players fitted with Zoran Vaddis chip-sets.

By-the-way, your KiSS player can read packed bit-stream, as long as only 1B-VOP is encoded. Which is in accordance to DivX's certification.


Cheers

I never updated the firmware on any of them except one time on Kiss because of my little sister -(she wanted GR (*.srt )subs).

I don't care about the Kiss anymore I stopped using it a long time ago - since 90% I encode with 2 b_vops and packed bitstream, but I'm almost 100% sure back when I was using it, it wouldn't accept packed bitstreams of any kind 2 and 1 b_vop neither, so there must be a fix/update in a firmware they released.

...out of topic now I think 99%

THX again

Is there ANY alternative to MPEG4 Modifier that does NOT need .net framework installed? (Gawd I hate that Microsoft bloatware.)

@Honeyko: Not that I'm aware of, but it runs just fine in Mono even on Windows aside from some cosmetic issues. In fact I just compiled a special version to work around those problems (related to form scaling) in Mono: MPEG4Modifier-1_4_4-MonoFix.zip.

EDIT: Now I remember MPEG4 Modifier was ported to Java, it's based on 1.3.4 I think so no OpenDML and no packing.

Color me stupid, but is there an intrinsic necessity for .net software in order to alter VOL headers? I'm just curious, is all. (I've been getting along without that stuff for years; the only software I've ever encountered which needs it are some x264 encoding utilities, and this program.)

(The ideal solution here would be a direct volume sector-access hex-edit which doesn't require stream-copying a whole enormous file just to change a few kilobytes. I seem to recall hearing of such a utility already existing awhile back, but forgot the name of it.)
