MPEG4 Modifier v1.3.4 Released (Updated 2005-Dec-14) - Page 18

First Id like to say thanks alot for this tool. I use it mostly to check wether my avi anime files use GMC or QPEL so I coudl play them back on a divx/xvid player.

I did have a question though. Unfortunately, I foudn that some of my anime wont work with this tool and I get the error message that they are OpenDML types. I know you dont support that, but is there anyway to re-encode the file or just edit it so its not opendml? thanks

celtic_druid · 27th December 2005, 07:23

Don't know if it supports ODML or not, but avicheck would tell you if a file uses qpel or GMC much quicker if that is all you want.

Agreed.... for a Sigma product it's pretty good

...open the file in VirtualDub and save it with DirectStreamCopy-mode for Audio and Video. Maybe You have to save it with the "save old format avi"-option.

ok i was able to do that and it fixed the problem, but i had another question about the program itself.

what im wanting to do is resize my xvid/divx videos so that subs display properly. i have made several test runs by using a custom Pixel AR, but the results dont vary as I would expect when i try different values.

the source is 640x480 so ive tried 600x450, 580x435, and a few other non 1.333:1 values. The strange thing is that when i view them on my dvd player on the tv, everything looks the same , squished a bit too much. 600x450 is the only one that looks fine, but its just a little too wide and the subs still get cut a bit. I cant fine tune it anymore then that.

would i have to add borders to correct the issue properly, or do i need to do something else in the program to resize properly?

trooper11 · 4th January 2006, 06:21

is this an issue i can fix using the program?

celtic_druid · 4th January 2006, 10:13

If you are talking about hard subs being cut off by overscan, then yes you need to add borders. I just changing the AR could stop the subs from being cut, but then you are compressing the image vertically.

I'd been searching for how to do batch unpacks and read this thread about peoplee using the command line option. In another search I found this
http://sibit.si/directsub/Mpeg4ModifierMod.1.3.4.zip
That modifies the GUI to add a directory select button for batch processing.

I'm glad the N-vop glitch was sorted - had the odd occurrance of this (on TV encodes usually) when I had 1.3.0.

Thanks Moitah for a great app

Moitah · 25th January 2006, 23:51

Check out Gambit's GUI for UnpackCL also.

nix0 · 30th January 2006, 21:37

Thanks, will check it out.

As Mpeg4Modifier doesn't handle openDML I'd been using Avidemux for those instances (though as its primarily a Linux tool the windows implementation isn't as slick), though I've just recently seen dimitrik's tip on using virtualdub with direct stream copy. Is OpenDML support something that will come (maybe the avidemux code would be useful), though it tends to be older files so maybe its relevance isn't so great?

Doubtful.

Appu · 31st January 2006, 13:47

Hi,

How are you checking GMC or qpel is present in the stream?. Just by checking VOL header or do you parse further till macroblock level to find out the required motion vectors are present?..

I am trying to find a tool which provied these info and which can deal with corrupted/wrong VOL header parameters..

regards,
Appu.

Moitah · 31st January 2006, 19:35

@Appu: QPel is determined from the VOL. But for GMC I actually do check the VOP, because DivX reports more warping points than it actually uses in the VOL.

SeeMoreDigital · 23rd February 2006, 19:00

Hi there,

I've just been over to DivX's HD web site and downloaded their Thank You For Smoking trailer.

When I ran it thru' MPEG Modifier it detects it as having just 4No B-VOP's.... Can this be correct?

Cheers

Moitah · 27th February 2006, 05:40

That is rather strange, but it looks correct. If you check out the frame list, they're all in the same area, and there are dummy N-VOPs to go along with them:

Code:

  3016: N-VOP(D) (0:02:05.791)
  3017: P-VOP    (0:02:05.874)
        B-VOP    (0:02:05.833)
  3018: N-VOP(D) (0:02:05.874)
  3019: P-VOP    (0:02:05.958)
        B-VOP    (0:02:05.916)
  3020: N-VOP(D) (0:02:05.958)
  3021: P-VOP    (0:02:06.041)
        B-VOP    (0:02:05.999)
  3022: N-VOP(D) (0:02:06.041)

Sorry if this question already came up in this thread, but i couldn't find the information: Does MPEG4 Modifier work on DivX3 files generally?

I tried two old DivX3's with wrong aspect ratio and M4M complained about them not being valid MPEG4 video (startcode not found at beginning of frame).

No. DivX3 is not MPEG-4 ISO compliant.

DFKT · 27th March 2006, 03:00

So the chances that MPEG4 Modifier will support DivX3 in the future are slim?

Nonexistent. What is there to support anyway? Support for DivX3 died out a long time ago. It's a hack after all.

celtic_druid · 27th March 2006, 03:38

There is a modified version of ffmpeg that can convert (not re-encode) DivX3 to MPEG-4. After that it will work with MPEG4Modifier.
