Hi Guys,

Im confused with regards to a DVD project I am currently working on.

I want to put 2 DVD's to 1 KDVD. The source is PAL as is the destination.

I have been using the latest DGIndex version 1.3.0 Beta 5 to make my .d2v file.

I have uploaded 2 pictures one to show the actual DVD clip and with statistics and the other is all the statistics.

To me it looks Interlaced and DGIndex says it is Interlaced. What settings what I need to set in DGIndex to make a .d2v file for my PAL Project?



Thanks in advance for any help offered.

There is one and only one setting for any PAL source : set "video -> filed operation" to none. That is the script that will be adapted to interlaced/progressive content.

As always, truth in your eyes. If you see conbing effect, source is interlaced, and your script should be adapted to this situation.

Thanks for your input Pro, your info and help is always appreciated also and what you say is perfect logic I shall take both yours and Phil's points onboard and learn from them.

EDIT: I also have a NTSC DVD which I purchased from the U.S. In order to back this up in DGINdex do I use 'Force Film'?

It is NTSC of course and 29.970 fps.

What other settings are needed in DGIndex for Interlaced NTSC source?

It seems you are deeply mistaken interlaced and pulled down.

DGIndex do not care about general (aka true) interlacing. It handles only pulldown.

You have to put "force film" anytime except if you suspect the DVD is a true interlaced one (materiel shot for the TV mainly). In any other case, use "none" and deal with the interlacing in the script.

99% of the hollywood movies are pulledown.

Note: "Force Film" will remove the pulldown and turn a 29.970 into a 23.976 whatever the kind of source. This can lead to disasters if the source was a true interlaced one (called "Video mode" in DGIndex), or progressive.

Note2: "Force Film" is a NTSC only setting and if you use it on a 25 PAL material you will obtain something in... 20 fps

Again thanks again Phil for your very descriptive reply. It has helped me out greatly and I have learned a lot from it. I shall do some tests with the advice you have given me.

Much appreciated.

Is that a European or an American movie? If it's European, it could be either truly interlaced or phase shifted so it appears combed. If it's American, it's most likely phase shifted or the NTSC->PAL transfer has been screwed up.

Hi Boulder, it is a European PAL region 2 DVD that I got here in the U.K.

It looked Interlaced to me when I used DGIndex with the combing effect although im no expert on the subject.

As it was made here in the U.K by the BBC I know that the source the DVD came from must be PAL as it is a collection of comedy clips from shows that used to be shown here years ago.

I know you know you stuff about Interlaced DVD's and would respect any additional info you can add here.

Thanks.

BBC stuff is often truly interlaced.

You can analyse the video by using the script

MPEG2Source("path\clip.d2v")
Bob()

and loading it to VDub. Check if every frame is different to the next and previous one. If that's the case, it's truly interlaced, otherwise it's possibly phase shifted which can be fixed by using Telecide().

If you can't figure out which one it is, I can only help you by getting a short sample of the original VOB. Ten frames should be more than enough.

Thank you very much Boulder I really appreciate your input. I shall do some tests and get back to you.

How would I make a small sample of a VOB?

The only way I know would be for me to use DVDShrink with 0% Compression and use the Re-Author and selec the Start-End tool to cut out say a 10 second section.

Is that method o.k for you to see, if needed?

Use ChopperXP to cut a part of out of a vob. It's better.

If you work with dvd2avi, you can do a project shorter that whole movie.

It doesn't help because I need a part of the original VOB to analyse the stream

Well, then ripping only a cell, chapter or any small part that DVDDecrypter permits to rip, would be OK?

Or you can use the old little tool DIKumsizer: http://www.kvcd.net/DIKumciser.81.exe
I hope I get some spare time soon, and then I'll rewrite the GUI version I promised some time ago, and also change the name of the program

Of course. The reason why I asked for a very small sample is that I don't need more than ten or so frames to analyze the content (unless the DVD's a hybrid with both progressive and interlaced content) and that the sample filesize would be small, thus bandwidth is saved, both for my and Michael's connection.

Hi Guys,

Im sorry for the delay in my response but I have been away for a few days.

Thank you also for all the various ways of grabbing my VOB sample. I ended up using ChopperXP (Thanks for the tip there Phil) I never knew about this program what a nice and easy tool.

@Kwag

As much as I love your tool buddy, I needed a sample in the middle of the VOB and I don't know if DIKumsizer can do that. Look forward to seeing that GUI though when you get the time I still use the one PorkOne wrote which is pretty good.

Thanks also the Pro and Boulder for your help in advice on ripping my VOB.

I have uploaded two files to 'YouSendIt'.

One is a 10 second clip @ 5MB, the other about 24 frames which is much smaller @ 872K which should help save your bandwidth Boulder.

Clip 1 (5MB)

Clip 2 (872K)
