VDmod size ... error? >_<

Post by post-it » Fri Jun 08, 2007 11:50 pm

VDmod size ... error? :oops:

I've used this software for years ( yes, years ) and I'm just now noticing something possibly wrong with the Sizing:

1) the DVD say's its 720 X 576 .. A52 Audio .. 8-)

2) VDmod say's its 720 X 480 .. 48k @ 192... :?

I loaded DirectShowSource and its 672 X 420 in both :?:

? am I missing something here ??

Your post doesn't make any sense.

Your DVD tells the resolution? I've never seen the resolution printed on a DVD, at least not in pixels. It isn't necessary, because the possible resolutions are very limited (720x576 would be proper PAL). And what the hell is A52 sound? DVD-Video supports PCM, DTS, MPEG1 Audio Layer 2, MPEG2 Multichannel and AC3 (Dolby Digital).

Sounds like a proper NTSC DVD.

You loaded DirectShowSource into what? And how did you do that? Presumably you made an AVISynthScript with DirectShowSource and loaded it into VDM and ??? Why the hell are you feeding MPEG2 via DirectShowSource? What do you think is MPEG2Source for? Ever thought about the possibility that the DirectShow playback device resizes your footage?

A/52 is an alias of AC3.
Wikipedia wrote:This codec has several aliases, which are different names for the same codec:

* Dolby Digital (promotion name, not accepted by the ATSC)
* DD (an abbreviation of above, often combined with channel count: DD 5.1)
* Dolby Surround AC-3 Digital (second promotional name, as seen on early film releases, and on home audio equipment until about 1995/1996)
* Dolby Stereo Digital (first promotional name, as seen on early releases, also seen on True Lies LaserDisc)
* Dolby SR-Digital (when the recording incorporates a Dolby SR-format recording for compatibility)
* SR-D (an abbreviation of above)
* Adaptive Transform Coder 3 (relates to the bitstream format of Dolby Digital)
* AC-3 (an abbreviation of above)
* Audio Codec 3, Advanced Codec 3, Acoustic Coder 3 (These are backronyms. However, Adaptive TRansform Acoustic Coding 3, or ATRAC3, is a separate format developed by Sony)
* ATSC A/52 (name of the standard, current version is A/52 Rev. B)

Qyot27 8-) Thank You
. When I right clicked the VOB and it said, "Audio Type: A52" and I was hoping it didn't mean AC_7 because I don't have that Codec ~_~

Hellfire ... yeah, but that's what is said!

a quick review might be needed:

1) WinXP, Explorer, D drive, right click the VOB ... say's its 720 X 576

2) I then opened it in VDmod, it said 720 X 480

3) I fed it through DirectShowSource, not knowing what the A52 was, and it reads 672 X 420 in both !?

actually, no! ... well, that's not true -- I was hoping it would solve the size mistery but it desided to make a third size available AND I was not prepared for that.

Is the dvd NTSC or PAL? how did you get explorer to give you the resolution of a vob?

-Purge- PAL and I just right clicked on the VOB itself; the properties thingy came up and it said everything in the Expanded Summaries locations.

is it just a certain PAL vob file or are all your PAL vob files resizing to 720x480 in VDUBMOD?

Lets say this: I wouldn't rely too much on VDM's MPEG support. For example, it ignores the pulldown flag, which is really bad for anime, since often 23.976 and 29.97 parts are mixed (NTSC). So it's possible that it fails in determining the proper resolution sometimes, though I think that points to an improper encode of the MPEG2 file. For example, my PAL-Version of Noir is recognized correctly. To make it short: Index your .vobs with DGIndex and frameserve them via AVISynth to VDM, using the MPEG2Source(...) command.

Sorry for the double post, but after sending the last one I got an idea: Do you load the .vob directly from the DVD into VDM or do you rip them first? If the latter is the case it is possible that your ripping tool converts them.

-Keeper of Hellfire-
. I'm old-school when it comes to DVD's -- rip, tare, shred editing.

. at work I use U-matic VCR's and Gen-Lock timers with simple fading from Tape 1, Tape 2, Tape 3, blah blah to make the final Tape. It is basically the same process as Editing with Software except that I have to set the timing for the VCR's to a Que-Point-Time to start and stop each section of tape(s). Then a timing Mark ( audiable tone ) is added so the program/commercail can play/rewind/start & stop on its own. These tones are stored in the unused audio tracks [ of which we have four to play with. ] Once the Video is completed, we can then Burn a small DVD from it and the computers can then pick any program/commercail free-style and nobody needs to remain in the editing department to Que the tapes.

. the only transition I like, because of what I do at the station, is simple fading 8-)
