How to create chapters using the Philips Video CD 2.0
Toolkit
Creating chapters is very easy. The first thing you do is to add a VCD 2.0 compliant MPEG-1 A/V
file to your asset list. Then, you create
an entrypoint (in Toolkit lingo this is called a chaptermark) where you want
each chapter to begin using SMPTE timecodes.
These chaptermarks are saved in a chaptermark file. Drag and drop each chaptermark into your
event list. Now you can use these
chaptermarks as you would any other asset in your event list.
- Add
VCD 2.0 compliant MPEG-1 A/V file to your asset list.
- Click
on the MPEG file. Notice the Name
and Timecode fields are now active.
- To
change an existing chaptermark, click on it to highlight it. Then you can change the Name or
Timecode fields. Click on Change
when done.
- To
create a new chaptermark, enter a new name and SMPTE timecode, and press
Create. The format of a SMPTE
timecode is Hours:Minutes:Seconds:Frames.
There are 75 frames per second.
For example, the timecode for 2 hours, 15 minutes, and 12 1/5
seconds would be 02:15:12:15.
- After
you have created all of your chaptermarks, open the Event window and
create new events for each chaptermark.
- Drag
and drop each chaptermark onto an event.
Answer “yes” to the question about renaming the event.
- You
can now drag and drop the chaptermark events either to a menu,
- or to
a sequence.
- You
can create chapter sequences by creating a sequence object using a
chaptermark event, then set the playing time so the sequence stops playing
at the point the next chaptermark begins.
If you leave the Selection Branch List blank, playback will
automatically return to the calling menu.
You can also specify an action.
In this example, when the chapter sequence named “Start” ends, the
Next action calls the chapter sequence named “Bit”. You can nest all of your chapter
sequences together so that you can use your Next and Previous buttons to
skip forward or back between chapters.
This can be done without having to split up your MPEG file into
separate tracks for each chapter.
However, some players may pause slightly when changing sequences,
just as some players pause slightly when changing tracks.
- You
can also create chapters that use menu objects instead of sequence
objects. Nesting menu objects
together will allow you to move between chapters using both numeric keys
and the forward and next buttons.
However, in order to use a menu object for each chapter, you must
split your MPEG file into separate tracks for each chapter. This is because the menu is actually
hidden in the background while the MPEG file plays in the foreground.
