PgcEdit v0.4

[r0lZ]

Humm. I have already fixed two similar bugs in the Tcl/Tk code. Seems that support for buttons with images is somewhat buggy.

Could you be more specific? What were you doing exactly when the problem occured? The problem occur everytime you click on the same button?

[jeanl]

well it happens every time I CTRL-click on any button (sorry, I wasn't specific earlier). And it happens on any DVD that I've tried so far...

Interesting problem.

Calendar Girls, R4. Title 3 is a whole lot of rubbish and is comprised of several separate PGCs (in effect 1 x Title 3 and about 6 "dummy" titles, not separately named as Titles in the VTST domain).

If I load up the DVD in PgcEdit and do nothing else other than simply saving it and close out, the next time I load up it gives me fatal errors telling me it can't read past the end of the code or something. Also IfoEdit won't do a Get VTS Sectors and tells me "somethng is wrong".

A huge IFO is created on save (about 1 Mb!). Of course, no VOB is modified.

I only tried this in v 4.3 - I haven't checked to see if this was a problem in earlier versions.

BTW: DVD Shrink loads the DVD OK to begin with and reports in extras "Title 3", and "Title 3 continued" (6 times). After that 1st save, it, too, won't load.

I ended up backing the DVD up OK by simply starting afresh and adding the titles and menus I wanted - no further problems. So the problem was with the titles I didn't backup - especially this multi PGC title.

I just wanted to make you aware of this situation.

Anybody else come across this?

Best regards

[r0lZ]

blutach, could you send me the original IFOs? Thanks.

Well, here my case. I use original DVD (bought over Amazon) that don't have my subtitle language and author new DVD with DVDMaestro. After that I copy original menu, IFO's and rest of VOB's. Now I have to modify original IFO and add new subtitle at 2nd position (I keep original english subtitle). Now I make changes in stream of that VTS where I have 0000 for first sub and add 1111 for 2nd. My 2nd sub stream can not be seen in streams attributes so I can't make changes but it is possible in IfoEdit.

[r0lZ]

OK, I understand.
I may add a function to add or remove a subtitle entry in the IFOs, but don't expect that soon. I have too many work for now. And, as you said, "it is possible in IfoEdit."
Sorry.

[ffroms]

No hurry. For now I'll use IfoEdit. Just do what you have to do and bring us even better tool :) (I'm doing some basic tutorials on Croatian with PgcEdit so I'm looking forward for new version).

Hi r0lZ, again I have to thank you for this amazing tool.

I, too, have a request for a new feature when adding new (custom) subtitles. Actually it may be a bit of a bug fix, aswell, so I hope you'll find the time to look into it!

When I add new custom subtitles, I do it like this: Demux the main title PGC using jsoto's PGCDemux, create a new (extra) .sup subtitle file using Srt2Sup and put it all back together using the DVD author function in IfoEdit. Then I use PGCedit to add a precommand so that my new subtitles will play by default.

The last thing I need to do is to change the subtitle colours for the PGC. It would be very nice to able to do this in PGCedit, too, so that I don't have to involve so many different tools.

BUT when I double click the PGC in question, and edit the subtitle colours using PGCEdit, I can only set the colours in RGB mode. Srt2Sup, which I use for making the new subtitles, gives me the colours in YCrCB mode only. I can use SupRemap to add my colours in YCrCB mode, but as I said, I'd like to be able to do it in PGCEdit, too, so that I can skip using all those other tools.

Why don't I simply once and for all find out what values, the YCrCB colours I used in Srt2Sup correspond to in RGB values, write them down and then use the subtitle RGB colour editing function in PGCEdit, you may ask?

Well, SupRemap has this general warning displayed: "Please be aware that it is not possible to get the conversion between RGB<->YCbCr to be as 100% as rounding and clipping errors are introduced. This means as you switch between colours and hex values the hex values/colours may drift!"

The way I see it, the correct way when it comes to subtitle colours in IFO files, is to use the YCrCB values only, and not the RGB values... Hence my request to be able to enter subtitle colours in PGCEdit using YCrCB values instead of/as a supplement to (like SupRemap) RGB values. :-)

The SupRemap program is not maintained anymore by the author, but you can get the latest version here, if you want to see what I mean: http://dvd.box.sk/index.php?pid=soft&prj=info&pol=0&plat=SupRemap

[r0lZ]

It is true that the conversion between RGB and YCrCB can introduce some little errors. However, the algorythms I use to convert from one format to another are the 'official' ones. So, you can be sure that what you see is what you get.
Also, as you can see, I use the built-in color dialog of the platform PgcEdit is running on. All those dialogs are using RGB, because RGB is the 'natural' color format on a computer.
I really don't want to write my own color dialog, just to be able to input YC color codes. And, anyway, when the colors are displayed in the dialog (or in the color table in the PGC Editor) I have to convert them to RGB.
If you really want to cut/paste YC color values, you can do it with IfoEdit. Though you have to convert them to hexadecimal.

Also, adding a new option somewhere in the PGC Editor allowing to enter YC color values is not a good solution: I retrieve the RGB colors from the displayed color table when you click OK.

I wonder if it is so important to have exactly the same colors in the final DVD. The subtitles are only subtitles, not real live images. Also, most of the time, you will use white and black, that are never changed by the algorythms. And anyway, when you add a new subtitle, there are NO original colors. Or am I wrong?

[CoNS]

It's correct that there's no "original" IFO when I add new subtitles. But I've created the subtitles using Srt2Sup and this program uses the YC colour table and it gives me the colours in YC values only. I believe Srt2Sup is the most popular and commonly used program when creating new subtitles from a text file.

Is it correct that in IFO files, the native colour scheme is in YC values and not RGB?

[r0lZ]

You will see that the black is not 0,0,0, and white is not 255,255,255. In fact, value 0,0,0 in YC is this strange well known green you see when the color table is not initialized.
YCrCb is used in the DVDs, because it is the standard for video.

@r0lz

Is it posibile with pgcedit to add/delete programs to menu PGCs? And can i delete some menu PGCs?

I'm editing one dvd, and after striping all foregin menus i got about 40 unneded dummy pgcs. there is total 55 pgcs, and i needed only 9 of them (first two and 26-32). I wanted to clear this a little bit. first 2 pgcs are dummy and then 7 normal.

- so i opened ifo in ifoedit and set "Numer of menus for this LU" to 9.
- reopened in pgcedit and set programs of those 7 PGCs to point at right vob/cell id's
- back in ifoedit i strpied all unneded vob/cell id's
- now again in pgcedit i put pgc commands from original pgc's (26-32) and finaly i got working dvd :)

is there a quicker way to do this? and what about pgcs with more than one program? (i had either dummy pgc or pgc with one program)

[r0lZ]

@M!ro

No. It is normally not possible to delete a PGC in PgcEdit. See here (http://forum.doom9.org/showthread.php?s=&threadid=85329&perpage=20&pagenumber=2#post570330) (5 posts) for the reason, and a trick to do step 1 of your example in PgcEdit.

You can add or remove a Program in the Cells table (in the PGC Editor) simply by clicking on the buttons of the "Program" column.

I don't know how to do it. I open PGC Editor for a specific menu PGC i want to edit, and it has only one program, how can i add another one? Or even better, if it's a dummy pgc, how can i add program/cell?

[r0lZ]

Why do you want to add a program when there are no cell associated with it? A dummy PGC may not have programs, and a PGC with only one cell may have only one program, no?

Adding a new cell in a PGC makes sense. But it is not possible for now. But you can use AddChapter for that purpose, if your PGC is in the Title domain.

[Lupo Silenzioso]

i have a problem with a dvd (ripped on hd) that i try to open with pgcedit.
The program says:

-------------
WARNING: The number of VTS stored in Vide_TS.ifo (£) don't match the real number of Title Set sotred on disk (5).

You should manually remove all files related to VTS 5.

If you really need this Title Set, ty to import it with one of the "Import title clip" macros or the "Import VTS Titles" and "Import Menu" utilities.
--------------
I also open the Video_Ts.ifo file with IfoEdit, and there are only 3 Title Set there.... this is very strange, isn't it?
I also try to remove the VTS_04_*.* and VTS_05_*.* and now pgcedit makes no warning.

p.s. the original dvd contains a JACKT_P folder, with 3 *.MP2 files in there. I have never met a dvd video like this! all the others have a VIDEO_TS (like this one) and a AUDIO_TS folder (that is not present here).

[r0lZ]

Yes, it's strange! Seems to be a bug in the authoring. This is why the warning pops up.

You may also try to open the original DVD in DVDShrink. It should complain.
Also, try to burn it with Nero (without the blank DVD in your burner if you don't want to loose one!)

The JACKT_P folder is legal, and is used to store still images in various resolutions, that some players are able to display to help identify the DVD, or as the background image when the DVD is stopped.

Normally, AUDIO_TS must be present, although it seems that it doesn't hurt most players if it is not.

[Lupo Silenzioso]

dvd shrink does not complain.... very strange.. i'll try to remove this unwanted vob and ifo from the dvd before burning it (on a dvd-rw!).
Nero Says: Reallocation file failed... what does it mean?

[r0lZ]

Take care. If the titlesets 4 and/or 5 are called somewhere, you will have some problems. Use the Info -> Calls Cross References to see if there are references from FP-PGC, VMGM or VTS 1-3 to any PGC in VTS 4 and 5.

You may also try to fix the numner of titlesets to 5 with IfoEdit.

[Lupo Silenzioso]

how can i know what PGC are present in the 4th and 5th ifo/vob? they are not loaded by pgcedit,as i say before.
I launch Call Cross References, but i don't know what i have to look for.. :(

And how can i fix the number of titlesets to 5 with IfoEdit?

p.s. what's the difference between VTSM and VTST? and TTN stands for..?

I want to add both, cells and programs. And i need this in menus, so addchapter won't do the trick :(
Do you have any idea when this will become possible in pgcedit? ;)

[r0lZ]

I launch Call Cross References, but i don't know what i have to look for.. :( The 1st line of each group lists the target PGC, in the order of the DVD. The following lines, indented, are the references to it. Of course, as you can't load the VTS 4 and 5, this is useless in your situation.

And how can i fix the number of titlesets to 5 with IfoEdit? Load VIDEO_TS.IFO, and go to VMGM_MAT, at offset [0000003e]: VMG Number of TitleSets. Change the 3 to 5.
Then, go to VMG_VTS_ATRT, and do the same change in the first line, if needed.

p.s. what's the difference between VTSM and VTST? and TTN stands for..? VTSM is the acronym for Video TitleSet Menu domain, and is therefore in front of every Menu PGC, except the VMGM menus (Video ManaGer Menu).
VTST is an acronym of my own, meaning Video TitleSet Title, and is used to identify all Title PGCs. The official acronym for title domain is VTS, but it is also used to represent the whole titleset, including the menus.
TTN means Title within Titleset Number, and is the relative number of the title within the VTS. The absolute Title number (which is displayed by the players) is defined in the VMG_TT_SRPT table, in VIDEO_TS.IFO.

BTW, I can't resist to this joke:
Q: What is the meaning of TLA?
A: Three Letters Acronym :)
Q: And TLAE?
A: Three Letters Acronym Extended :D

After that, I may add the function you want. But there are tons of user requests in my TODO list as well...

Do you probably mean "change 3 to 5"? infact now , if i open VIDEO_TS.ifo and go where you told me, i found the number 3. Also in the other section.

[r0lZ]

Oh yes, of course.
Sorry. I'm a little bit tired!
Fixed in my previous post.

[CoNS]

Hey r0lZ, I know your todo/request list is rather long already! And probably someone else has already asked you this earlier:

Are you considering developing the blanking function/macros further in the future so that you can blank out (replace with a 10KB vob) a single PGC within a VTST or VTSM? And also blank out a single cell within a (menu) PGC?

I know that it's possible in VobBlanker, but I really like the idea of being able to blank the PGCs/cells "on the fly" instead of having to copy and overwrite the processed .ifo, .bup and .vob files that VobBlanker made and then afterwards have to get VTS sectors to make it work...

Because of the above mentioned limitations of both PGCedit and VobBlanker, I now use PGCEdit for as much blanking as possible, but when it comes to blanking a single PGC inside a VTS with more PGCs, or a single cell inside a PGC, I have to use VobBlanker. It would be great if one program could do it all!!

[r0lZ]

No, sorry. This is not in my TODO list for now. As you said, you can use VobBlanker to do the work. It's free, and works pretty well.

Also, PgcEdit is not a VOB editor (although I have added some basic functions, like full blanking, and the ability to blank a cell by adding a blank VOB cell at the end of the VOB.)

If you want to access this feature from within PgcEdit, you may add VobBlanker in the Tool menu... ;)

[CoNS]

Okay...! Must live with that! :)

[Lupo Silenzioso]

i make the changes you told me. I click on save and exit ifoedit. (what does the function "Get VTS Sector" do?? )
But when i open it with Pgcedit the program warns me: Fatal Error! Pgcedit is trying to read data after the end of a table. This means that a Lenght of table value is probably wrong. Please try to fix the problem with IfoEdit. The missing Value may be fixed to 0, but this could lead to strange results. Do you want to fix the value and continue anyway? (NOT RECOMMENDED!


How can i fix this problem with ifoedit?

[blutach]

@lupo

I had this problem too. Sounds like you need the new 0.4.4 beta.

[jeanl]

r0lZ,
Here's a suggestion for a new feature:
- How about allowing us to preview a whole titleset? This would be useful for people who'd want to blank out the whole titleset and replace the vob file (which is really fast), but aren't sure that there isn't something they want to keep in the titleset. Currently, we have to preview every single PGC in the titleset to check that (or use another app). Maybe you could add that to the right-click menu?

Thanks,
Jeanl

[blutach]

LOL jean. Save a couple of clicks? :D :D

BTW: Nice new guide.

Hey, it can be many more than a couple clicks!!! I've seen VTS where there's over 30 PGCs... Of course, it's always possible to launch PowerDVD and drag/drop each VOB file in the VTS... What a pain though... ;)

Jeanl
P.S. thanks for the comment about the guide!

[blutach]

One easy way I have used in the past (but now tend to abandon in favour of rolz's preview) was to load the disk up in DVD Shrink and have a quick look at the titles in extras. 2 minutes later, you're done!

Regards

[jeanl]

yes, you're right, but there's the annoying "analyzing" time required before you can take a look. On some DVDs, it can be somewhat lengthy (1-2 minutes)... Now, I'm totally nitpicking, I know!

Oh, another option:
- Launch PgcEditPreview straight from the bin directory created by pgcedit (or DVD2AVI for that matter), and drag/drop the first VOB file (VTS_xx_01.VOB). The preview loads the whole set of vob files, so the slider will let you scroll through the whole VTS...

In fact, we could probably set that up as a tool in PgcEdit! If pgceditpreview could be made to open a VOB file passed as an argument... That should be easy.

http://home.tiscali.be/debie.roland/pgcedit/third_party/2cool/blank_titles/blank_vts_titles.htm

[lark]

yep, i knew about the possibility to replace by blank or imported,
but what i'd like to achieve is to delete the whole VOB & IFO.

e.g. i've a DVD that has VTST 1 & VTST 2.
VTST 1 contains just warnings, studio logos and stuff that i don't need.
so, i'd like to delete VTST 1 and 'rename' VTST 2 as VTST 1.
obviously i cannot just delete 1's VOBs & IFOs, because it violates the DVD spec. in addition i cannot just rename 02 VOBs & 02 IFOs to 01, because they are referenced in video manager.

obviously there are DVD's that have e.g. 6 VTSTs and from where i'd like to remove something from the middle (e.g. VTST 3).

so, i'd like to have an automated procedure for that. perhaps that already exists, but i just haven't found it...

regards

[CoNS]

A question about how the Blank all VTST and Blank all VTSM macros in PgcEdit work:

I use these macros to save space on my disc before compressing a DVD9 to DVD5, so I use the "Replace all Menus/Titles with a blank frame" option. But what does the sub options about killing playback exactly mean? I know it's about converting post commands to pre commands, but I'm still not quite sure of the consequences of selecting one option instead of the other.

Does the "kill playback" term refer to skipping post/pre/cell commands or to setting the video playback time of the blanked Menu/Title to 0 seconds? Or both?

Lets say that I'm blanking out all titles in a VTS, which is in this example is only one title. The title had originally a video stream which played for say a minute. I want to make 100 % sure that when playing the DVD after blanking, I don't have to sit and look at a black screen for a minute...! Does it matter which of the three options I choose?

[lark]

@cons

i assume you refer with those three options to 3 option buttons under Replace all Titles by a black frame -option.

reading 2cool's guide, it debends on the content (are there cell cmds or not): if there are no cell cmds, 1st and 2nd option do the same and you never see the clip (you don't have to wait for a minute in front of black screen).
if you select the 3rd option (don't kill playback), you'll see the black frame, but i've no idea for how long (you can always try with a sw player before burning the disk...) ;-)

regards
t :)

[CoNS]

Ahh, ok, so it's a matter of skipping it totally or seing a black frame in millisecond? If the original, now blanked out title/menu had a video stream that lasted a minute, I'll never have to sit and look at a black screen for a minute before proceeding, no matter which of the three options I choose?

[r0lZ]

The original duration of a PGC depends on three factors: the length of the video (or audio) coded in the VOB, the Cell Still Times, and the PGC Still Time.

When doing a Blank Out Menu/Title, PgcEdit replaces the VOB with a verry short one, and fixes all Cell Times to 0.
Furthermore, if you selected the option to Kill Playback, it copies the post to pre commands.
When the kill playback is done, you will probably not see the black cell at all. But there are cases where the black cell MAY be shown even when the playback is killed.
As the cell duration in the VOB is now verry small, and the Cell Still Time is 0, the black cell will be shown for less than one second (the exact duration depends of the speed of your player, when seeking to the next PGC to be played.)

There is still one case where the cell may be played for a long time: if the PGC Still Time is > 0, the last cell of the PGC will pause for that number of seconds. (Note that this pause seems ignored when playing the DVD with a software player, but is used by my Sony standalone.)
I forgot to reset the PGC Still Time to 0 in the Kill Playback routine. This will be fixed in the next release.

For a long and somewhat technical explanation on the Kill Playback method, look at this post (http://forum.doom9.org/showthread.php?s=&threadid=79853&perpage=20&highlight=pgcedit%20kill%20playback&pagenumber=4#post544293) and the following posts. (Continued here (http://forum.doom9.org/showthread.php?s=&threadid=79853&perpage=20&highlight=pgcedit%20kill%20playback&pagenumber=5#post545607).)

[blutach]

@lark

You can pick and choose what titlesets you want, just so long as you have a your VIDEO_TS.IFO/BUP and VTS_01.IFO/BUP and VTS_01_0.VOB (this itself can be a 10k stub). The rest is up to you, so long as you don't "break the navigation" of the DVD.

For an example of how to do a main movie plus menu look here (http://ifoedit.wh.fr0zen.com/menuidiot.html). (Don't forget to do a Get VTS Sectors afterwards).

Note, in PgcEdit, you can start off with a "blank disk" and import menus and titlesets at will. I do this quite a lot - it totally eliminates unwanted junk and basically let's you have the DVD as you want it. Again, you will need to check the DVD's navigation (with the trace function - including menu buttons) and where "navigation breaks" occur, redirect them to "existent" PGCs.

lark, why would you want to do that? Is it just so the result is a bit "cleaner" (i.e., doesn't have "stubs" still around)? If so, the result is probably not worth the effort, since the "cleaned-up" DVD would then be functionally equivalent to the one where you still have the stubs, right?
Jeanl

[2COOL]

@r0lZ

Can you put a count flag on each gprm and sprm to tell us how many times each register has been changed during trace? Say gprm 2's value has been changed 3 times so a display somewhere will tell us 3. Don't know if you want to widen the watch window but I can see something like this.

GPRMs

0 [ 4 (3) ]
1 [ 12345 (999) ]


Or maybe a tooltip on each button would be better. It would be also nice to know what PGC the last change occured but that would be asking too much.

BTW, I'm still seeing invalid values besides language codes in my Watch's input language field.

[jeanl]

2COOL,
you can put watch points on gprms, trace will stop when they're changed. That's very convenient, maybe a beginning of an answer to your problem...
Jeanl

[2COOL]

@jneal

It helps...for the time being but my request is still convenient to have. Just want to keep more tabs on registers without manually doing so.

Has this been brought up? Sorry, I didn't fully read this thread. I had encountered a nasty bug, IHMO, during my trace. I had only checked these on.
