    Adobe Premiere CC freezing while conforming .VOB

    TaylorH Community Member

      Hi all,

       

      First of all, Happy New Year.

       

      I am using Premiere CC and have run into something niche. I have received some old .VOB files and brought them in to see if Premiere would take them, and to my surprise it did with some of the files. It conformed fine as well. Now on some of the more lengthy .VOBs it froze. One one of the clips it conforms all the way until the end and then freezes. So I restarted Premiere, same thing. So I restarted computer, same outcome. So I did some reading and referred to this article about .VOBs - http://forums.adobe.com/thread/464549. I do have MPEG and initially threw the files into the program to see if I could view them there before I put them into adobe. Well you can't preview them there so you have to export which is a lengthy process. I just don't understand why some are ok and some simply are not.

       

      My Specs:

       

      Mac Pro

      32 GB RAM

      8 Core processors

          its been a while since I fooled with vob files ..but basically the way the vob files are created to contain all the info that the overall " film " has ( and disc ) is done to accomodate lots of stuff.

          Some are not simply video and sound ...and it depends on where you got the vob from and what is on the disc. For example, there may be ( in a commercial dvd for a movie ), chapters and special graphics and pop up windows and all sorts of strange stuff...including various menus etc...

           

          Some of those vob's will not be happy in any editing program, but only work with the links on the disc it came from...

           

          some vob's may have some video and sound, but then get into other stuff .... as the vob thing is sorta split up into particular size files in byte count ...

           

          anyway, if you got the vob stuff from a commercial source it is not unusual to not be able to load some. If you got it from " dailies" then you should be able to see all the vob stuff...it depends on where you got the stuff and so on...

            After dealing with them for the past could days I finally diagnosed the issue with the luck a single program.

             

            It seems like the issue was that it was a .VOB fragment. After I posted this  I gave up on the conforming and decided to transcode. Well, MPEG Streamclip froze, Adobe Media Encoder froze, and then finally Compressor somehow read the fragment. I was able to transcode to ProRes 422HQ only to find a 7 second fragment. It seems that whomever transferred the tape to the .VOB format spit out fragments because I found the fragment clip within a larger clip. I double checked my fragment clip with the program "media info" and it was confirmed. A seven second fragment for a bundle of work.

             

            Thank you for the reply I hope this problem and solution help someone not break their Premiere in the future!

              That dvd stuff is sorta standardized ( is supposed to be technically very tight re: code and creation of dvd )..and is actually owned ( copyrighted or patented or whatever you call it ). In other words, every single program that burns DVD's is supposed to handle the creation the same way according to standard.

               

              It's not a matter of a person 'choosing' to do something one way or another when using the program to burn a DVD. It is more a matter of how the 'program' to burn dvd has implemented the standard.  Believe it or not.. there is some leeway in there due to translation from Japanese to English and so on... some programs to burn dvd do a better job than others...but the basics are the same. No 'user' of the program to burn dvd has any control over that.. the program is the thing.

               

              I'm glad you got the video and sound portion of your vob file.. good going. it's like you became a video forensic expert !

                one last note...

                 

                as you know the dvd ( and vob files on it ) are highly compressed and are a " final product " ...and are not meant to be " edited " ...it is what you might call THE FINAL PRODUCT FOR VIEWING... so it's kinda a tribute to adobe that you can even GET that into the editor and play around with it ( edit ) and not lose that much info and quality when you're done... relatively speaking...

                 

                thought I'd give adobe a slap on back for making it possible

                  Well you are exactly right about the .VOB format. It wasn't actually delivered on a DVD. It was delivered in the .VOB format on a hard drive thus why I brought it directly into adobe. It was actually VHS tape transferred onto that format for somereason and then delivered via hard drive. I knew it was a DVD format and agree that it was a feat in that Premiere somehow managed to read most of the non-fragmented files. The only explanation I have based on your explanation of the .VOB format and the fact that some of the files were fragmented was that the person transfering the media probably had some sort of error on his end. Luckily technology allowed me to see the issue than for me to fish it out!
