Joining different VOB files together

[siluet]

I would like to join a few VOB movie trailers together and put it on one DVD. There is tutorials how to make this using VOBEdit and IFOEdit tools. What's not clear: will the VOB processing/joining with VOBEdit and IFOEdit somehow affect the clip quality(video & audio)? Does that affect the encoding somehow? The VOBs comes ripped from various sources.

Use instead gui for dvd author. The video will not be reconverted.

[siluet]

You mean VOBEdit/IFOEdit will reconvert, and GUI for dvdauthor - will not?
Do the VOB files need have same video/audio encoding to play DVD correctly?

[Baldrick]

No, I mean that the vobedit/ifoedit method is old and might not work that well.

You can mix different videos if you use separate VTS/Tracks(supported in guifordvdauthor). But if you mix PAL and NTSC clips it might not work on all DVD Players.

[siluet]

if there is a mixed PAL and NTSC clips, preferred DVD standard can not be set from GFD?
But will work on region-free DVD players? GUI for dvd author is not standalone program, installation requires?

The DVD specification does not allow for mixing NTSC and PAL on the same disc. Very few authoring tools will therefore allow it. DVD Lab Pro will, if you turn down the compliance level. You also have to put the NTSC material into a different titleset to the PAL material. Not all players will be able to switch correctly between the two formats, so do not expect perfect playback if you do this.

GfD will do it, after you click through a warning.

I do many discs like this, they play on every player I've tried (this is PAL country, and all players and TVs are multi-system).
Sometimes the menu looks weird, but the videos play correctly.

I suspect that most PAL capable systems will play these mixed discs.

[siluet]

which from commercial DVD authoring tools is most suitable for joining VOB files and produce fully compliant DVD format? (mixing PAL and NTSC format is not a goal)

[guns1inger]

Where do your VOBs come from ? If you have complete DVDs then use something like PGCDemux or DGIndex to demux back to elementary streams, then use any authoring tool you like to create you DVDs.

[siluet]

I don't know. It's just several VOB video clips ripped from various DVDs. Does it possible put also WMV videos on DVD without re-encoding them?

No.

If you burn them as data, yes. If you want a DVD, no.

Demux the VOBs and use a real authoring tool.

[siluet]

what is purpose to Demux VOB and which program is for this? Will the demuxing somehow affect video/sound quality? I want try DVD-lab Pro authoring program, it seems it supports VOB files as inputs.

[manono]

The purpose is to separate out the audio and video into their own streams. gunsl1nger already told you how to do it, with DGIndex or PGCDemux.

I want try DVD-lab Pro authoring program, it seems it supports VOB files as inputs.

You can demux them yourself or you can let DVDLab Pro demux them. One way or another they have to be demuxed.

[siluet]

Can DVDLab Pro do this fully correctly?

[manono]

Yes.

Hi Siluent,
Perhaps u can folow this if u want use GFD. I m using GFD to make dvd of my own.

1) First convert all the .vob files to .mpeg using vob2mpeg.
2) Install & open GFD. from there u can select NTSC/PAL & other fatures using settings option. Then drag the mpeg files from left pan to right pan 1 by 1, click on create dvd. it will crete dvd in your hard drive in selecteed destination without changing quality & sound.
If all ok, then burn to disk, thats it!
