How to get chapters to number correctly

[Ogmium]

I am making DVDs of music videos where each clip has a number of points which the artists would like to fast forward to. However when you use the chapter marking (flag) point these are numbered as chapters inside each clip. I want to have twenty clips with a chapter points at the begining of each clip and to use the remote control to forward through the clip. The way it works at present I have to put flags at the end of each clip to make sure it will play through to the next title but then the back chapter button will only reverse to the start of that clip and the forward button on the remote stops at the end of each clip as it plays through.

If I compile all the clips into a single track with chapter points all the way through the file would be too big to load into workshop2 - what is the best way to do this? I'm obviously not doing something right

Hi,

I don't understand what you want to do.

One can mark chapters in a video for the *Next Chapter* (different wording for different DVD players) function.

Video A has 12 chapters. Pushing, skip chapter or next chapter moves to next point.

Really??? If it will fit onto a DVD, it should fit into Workshop.

You can link some or all chapter-points to a menu-button.

If I understand your goals correctly, you have two choices:

1- Make one long title with many chapter points.
Put a chapter-point at the beginning of each song. Link these beginning-song chapter points to a menu-button. Add "extra" capters wherever you want (up to 99)... Not all chapters have to be linked to a button.

Using this method, the video can be continuous, and although you can start it at any chapter-point, you cannot make it stop at the end of a song.

I've done this with concert videos. ...Select a song from the menu... Press the >>| button and it skips to the guitar solo in that song... Press the >>| button again and it skips to the beginning of the next song.


2- Make several titles (i.e. one for each song) with several chapters each (up to 99). Link the titles to the menu.

Using this method, you can make a playlist for each menu button, and you can play one or more songs, and then skip back to a menu, etc. However it will have a gap between titles... no good for a concert video.

Firstly I am working in PAL in the UK.

Secondly I am importing mpg or m2p files into workshop2. I have 1gig of ram and 200 gig of local drive resource. If I try to import any files over about 500MB the whole thing freezes so there is no way that I can import a single file of 20 tracks of audio and video and then put chapter marks on - the obvious solution as one single file. If it fits on a DVD it certainly doesnt fit into WS2 on my version - what am I doing wrong?

The projects I am working on are an average of one hour in duration and recorded at 4300 CBR.

what are you using to encode your mpeg videos? check if it has an option to use "closed gop's"

[Ogmium]

I am using Pinnacle Liquid Pro to encode with the settings we have always used:

GOP setting I frame only check box unchecked
size 12 (N value)
Cloased GOP FRequency 0
Reference Picture Period 3 (m value)
Sequence header frequency 1

Look forward to hearing from you - I'm afraid this means nothing to me.

[GeorgeW]

I am not familiar with your encoder, but can you put a 1 in that Closed GOP Frequency?

[Ogmium]

Yes you can. I also have Porcoder which can reset almost any setting. I just dont want to re-encode the project to find it doesnt work. What should the correct settings be for a Pal project?

if you don't want to re-encode everything, then try a small test to see if it has a chance of working.

encode a 20-minute video at about 7000kbps with audio at 224kbps (using the closed GOP's for your video). This should produce a file that's about 1gb -- see if that imports any better than your current 500mb threshold.

[Ogmium]

The test didnt work - system hung just like before. So I ran an analysis on the GOP of the file and got the following:

Analyzing 0, 6, 12 TAPE6.MPG

SystemHeader- VBR, VidBound= 1, AudBound= 1

OK

It ran OK on desktop media player and on a hardware decoder to a television but was different from our old files which showed:
