H.264 does not carry the Encore chapter info unless the Chapter is named in Premiere. So my guess is that your chapters aren't named and you exported as H.264. There was a thread in the Premiere forum where we couldn't figure this out. MPEG2 export does not have this issue.

I don't know which versions of Premiere, Encore, and Matrox drivers you're using, but from the Matrox "Release Notes" for 5.5 I found the following -

http://www.matrox.com/video/media/pdf/support/windows/mxo2/doc/en_Matr ox_MXO2_Release_Notes_5_5_1.pdf

When you export an Adobe Premiere Pro sequence that has chapter markers

to a Matrox MAX H.264 file, the chapter markers are not exported and

therefore won’t be available when you import your exported file to Adobe

Encore. (Ref# 51780)

****

So, it looks like you will just have to plan on adding chapter markers in Encore to use the MAX workflow

Oh, boy. Two ways to lose chapters and mess up the work flow!

That sucks. I had set and named all the chapters in Premiere so they would export into Encore. I wonder if there is a way to export the chapters to some kind of text file and then import them in Encore?

No chapter import. It has been a topic for feature requests, but so far no go.

It is painful.

As a workaround in the past, I write down the timecode in PR, and type it in EN.

By setting them in PR, you assure that the encoding sets gops where you need them.

Actually I click on the timecode in PR, copy, then click on the timecode in Encore and paste. Still annoying when you have several chapters. But as far as setting the GOP limits in the right places, I'm not sure Premiere is even doing that. In another project I set Encore chapters in Premiere, then encoded from Premiere using its own MPEG-2 DVD encoder, and Encore recognizes the chapters, but they are not frame accurate, which is obvious because I set a lot of them right in the middle of a fade in-fade out where it should be completely black, and Encore shows the chapters a few frames before or after. And this has nothing to do with the Matrox encoder, so I don't know what's the deal.

When using a GOP structure file, Encore will only be able to place Chapter Markers on I-Frames, and not on the "difference Frames."

Good luck,

What's a "GOP structure file"?

Sorry about that.

GOP = Group of Pictures. In many formats, there are only I-Frames (with all info) about every 8 - 15 Frames. All between those are "difference Frames," and do not contain all of the data to form the image of the Frames. This article goes into more detail: http://forums.adobe.com/thread/544204?tstart=90

Good luck,

But his point at post 6 is that he sets the markers in PR and exports from PR as Mpeg2-DVD, which should result in accurate placement.

Sebasvideo, can you confirm that the marker timecode in PR is the same as the time in EN?

Stanley,

Per the block quote, I was referring to the MPEG-2 file out of PrPro.

If ADL is used, or a DV-AVI Export from PrPro w/ En Chapter Markers, the Markers should be on the Frame chosen, and in those cases, GOP would not play a role.

Right, I know what a GOP is, I wasn't sure what Bill was referring to as "GOP structure file". But I know that the main point of setting DVD chapters in most NLEs is to ensure that there will be an I frame at that exact frame so the chapter break can be accurate.

That said, I opened the project in Premiere and I see that all the Encore chapters are moved from where they were supposed to be, which I have no idea how it happened. Maybe I made a mistake and did an unwanted trim operation somewhere.

I hate it when I do that. Let us know how the reencode goes.

If I understand your point. Same is now true for mpeg2-dvd out put from PR (or ame).

The way I did not interpret it, but perhaps what you meant, is that a PR project with markers, having done the export, can't have a gop issue for the markers in EN, since they will be on GOPs.

Also looking for a better work around for this!

The export SHOULD be made be sensible enough to drop/force in a keyframe whether ever you put a chapter marker regradless of underlying GOP in source

Without this feature the workflow sucks using 3rd party chapter inserters on MAC, may as well use FCP X, which does support it.

I have not tested the various issues here recently, but I believe that when you export MPEG2-DVD from Premiere with Encore markers, it places an I-frame.
