Does re-authoring VOB files with TMPGEnc DVD Author, or DVD-lab better

[MarcMiller]

Hi
I have been reading VOB file re-authoring post on these forums which involve the demuxing and muxing VOB files, but the posts recommend you use TMPGEnc DVD Author, or DVD-lab if you want to re-author with menus. So I am wondering if these products offer better quality by not doing needless reprocessing like the process of demuxing and muxing to re-author would?

if your creating home movies from a cam..i.e..MiniDv or vhs or any camcorder...then they do the job. I would say DvdLab Pro is a ittle complex to understand fo the average person. TMPGDA is dead simple.

If your importing new stuff for menu creation, and if you import to avi..then you could use AVStoDvd and output those avi's to "elementary streams"..then use DvdAuthourGUI..both free apps...or you could use DvdStyler...there are many free authoring apps that do a good job

or if your trying to create menus for an old set of videos, they say Womble will create menus w/o re-encoding those already created mpeg2/vob files

OK
thanks for that reply

Here is what I'm trying to do re-author new compilations of music videos both from commercial collections I own and can decrypt and once I can download from the Internet Pro shot videos and a like. I would like these new compilations to have menus and the highest possible quality. So is the suggestions I have received above already the best I can receive or are they still others ways to do this I should consider?

i've actually done the exact same as your doing. a few yrs ago i did it with some old videos that were in .vob format...used tmpg authoring works and it went over well...there's a setting in it that i cant remember that lets you "not" re-encode those files..i think its called smart rendering or sumthin like that. Womble lets you do it for sure...it has a graph at the bottom of its GUI that shows you if it will stay the same or be re-encoded when you add a menu

Not sure what you're talking about there as de-muxing and muxing change nothing, it is just a process the separate the video and audio into their elementary streams, there is NO quality loss by simply de-muxing or muxing.

DVD-Lab does not do any re-encoding.

TMPGEnc DVD Author does not unless your source is not dvd compliant or you set it to re-encode.

I would like these new compilations to have menus and the highest possible quality. So is the suggestions I have received above already the best I can receive or are they still others ways to do this I should consider?

That would be totally up to you and how nice of menu's you can create with quality sources of video and or still photos.

TDA does have basic menu's you can customize to an extent.

DVD-Lab has more options but it is more of a pro tool for you to import menu's, video's, audio, etc for menu's that you already created in something like Vegas, Adobe, etc.

And as moontrash stated, DLP is pretty advanced and if you don't have a good knowledge of a dvd structure & how things work you can muck things up pretty good or take a loooong time to figure it out.

Where is all this obsession with VOBs and demuxing coming from anyway?.....and "VOB format"?.....WTF is that? VOBs are part of EVERY DVD(video) structure!!

Where is this crap coming from?
Every DVD contains VOB files.....and demuxing is is almost NEVER necessary.

OK
I got my words confused with my first question on this thread. I thought that if I did demuxing then cut out the songs that wanted of say a group of songs being sung by one singer then Multiplex the video and audio together again I would the preserved quality by doing minimal reprocessing. I saw that there were cutters that claim to only reprocess the endpoints of what you are trying to cut out. But I agree a software product that will do this work for you without having to demux vob files would be the way to go if it also did minimal reprocessing to preserve quality of the original. I am now testing the Womble editor mentioned above to see if it is such a product that will preserve quality and also as I mentioned above let me create menus. I remember testing this product I think years ago and at that time it was difficult to get exactly the menu you desire. Does this forum have any good tutorials on how you use the Womble editor?
