Chapter Problems BluRay

I'm putting together DVD and BluRay versions of a multicam concert. Everything is great other than this nagging chapter issue.

My project is set up in DVDA6 and works great in preview. After I encode the BD .iso the chapters are either in the wrong spot or absent altogether. If I open the ISO with VLC or iDeer player the chapters are present but about 10 seconds earlier than they are in the DVDA timeline. When I try playing a burned BD in my standalone player there are no chapters at all.

The DVD version of this project works just fine in every aspect.

You have to be careful when creating a project that you will use for Blu-ray and DVD because depending on the workflow you could end up with problems.

1) Blu-ray and DVD handle Chapter location differently. DVD requires that a chapter must occur on the I-frame of an Mpeg2 stream. Blu-ray does not care.

Best practice for creating chapters is to create and name them in VegasPro NLE timeline and then export the markers in the render of the video stream for DVDAPro. Because DVDAPro will locate the chapters correctly regardless of the DVD or Blu-ray positions BUT only if you have mastered separate and distinct projects for each type.

You have not given any clues about your workflow that you used - please tell us about your approach to create two different kinds of optical disks.

I created a .m2v file in Vegas 12. Them add to a new DVDA6 project. In fact I've started from scratch several times with the same results.

The .m2v file has markers from Vegas, but they do not appear when the file is dropped intro DVDA. I then manually set up the chapter points. I preview in DVDA and the chapters work perfect. I encode to .iso and open in VLC or iDeer. Both programs show the chapter points appropriately in list view but when I select chapters I'm either 10-15 before or after the marker I inserted. Very frustrating.

The markers will appear correct and appropriately placed when you do a render from the NLE - if they are not appearing then you are doing something wrong. If you render more than once - you have to clear the bad markers, by taking out of the project in DVVAPro, wiping out the directory where you did the render, and then re-render to a different name in the NLE - those steps in that order to reset your import properly.

Don't trust software players, VLC or anything else to be your guide to meeting the standards necessary for proper QA of a burn for set-top players.

I am re-encoding from Vegas 12 with all markers deleted (as they were not coming through to DVDA) and I will add chapters in DVDA. Will see how it goes.

It's all very odd though. VLC and other players have misplaced chapters, while my set top doesn't recognize that there are any at all. Hopefully clearing the markers in Vegas is a step in the right direction.
