Vob splitting

[DJ_Izumi]

I was just curious, is splitting the vobs at 1GB absolutly necessary? If I were to author a DVD with just one large 4GB vob, is my DVD player just going to crash? Is it a limitation of the file system or something? Or is it just an older standard?

Not sure how (or why) you would author one huge VOB file, but for reference it'd be a coaster. Splitting the DVD into 1GB chunks is how DVD's haved worked since the dawn of time.

I would imagine, without proof or documentation, that the reasoning behind this is to make it easier for the DVD player to read the disc. After all, a set-top DVD player is still just a computer; like all computers, when a file is opened it is put into the computer's memory for faster access-- while most systems obviously don't have enough RAM to load an entire gigabyte, it's much more managable at 1GB than 4.3 or 8.7.

Well, I was sorta manually shrinking a DVD using Tmpgenc (DVD Shrink sucks), I ripped all the vobs to one single large vob, and will load that vob to re-encode the video stream to a lower bitrate, I'll then remux the the vob with the new video stream.

I guess I can use SmartRipper to splice up the large vob into little vobs by telling it to 'Rip' my new shrunken DVD and make it vob split every 1gb.

I hope this works.

IfoEdit is the program you need - it can both re-mux the video and split VOBs into 1Gb files in one operation.

By the way, please do not insult DVD Shrink, especially due to its being a freeware and very highly regarded in general. You simply noticed, apparently without realizing it, that there is a quality difference between transcoding (DVD Shrink) and re-encoding (TMPGEnc).

I thank some dvd author program split the vob file any ways.
Try using it in TMPGEnc DVD Author and output it to see if it split
the vob.
