Q: Why won't iDVD create chapters?

"I create chapter markers using iDVD and Yosemite all the time, (I use iMovie HD 06 and iMovie 11)"

The AppStore is currently selling iMovie 10.0.7. Do you mean iMovie 11 as in the year '11?

Oh, and are these chapter markers fixed interval, or can you do random placement?

Markers created by iDVD are a set intervals.  However, iMovie 6 HD can add them at any interval.  Just don't add them within 2 seconds of any transition that's added between slides.

I forgot to add that iMovie 6 HD is not compatible with Yosemite.

It works fine for me.

Yosemite has a bug that incorrectly identifies iMovie 6 (a.k.a. iMovie HD) as not compatible.  iMovie HD works fine with Yosemite.  Below is a workaround that many use until this bug is fixed.

Find iMovie HD in your applications folder.

Right click on it, and select “Show Package Contents”.

You will then find a folder named "Contents”.  Open it.  Then open the folder named "MacOS”.

There you will find "iMovie HD".  Double-click on this, and iMovie HD will launch.

Then create an alias. iMovie HD starts directly from the alias.

Please report the bug to Apple, the more reports, the sooner it will get fixed.

Based on these posts, here's what I've been able to find out.

Last week, Apple released an update of iMovie '11 which is what I have. After updating Yosemite with the latest security update, I managed to get iMovie updated to 10.0.7. This version of iMovie allows you to add chapter markers wherever you want, then share directly to iDVD. iDVD then sees and posts the chapter markers as scenes. An Apple support article iDVD '09 (7.x): General specifications and requirements for iDVD states that iDVD will only recognize 99 chapters, which saddened me, because the project I'm working on is a DVD that accompanies a music book, so I marked each of the exercises as chapters. It turns out that iDVD recognized all of them, and there are 218! Thank you for your posts; it made me do my own homework and solve my problem.

Have you created an iDVD project with a movie from iMovie 10 and got a second menu with scene selections?

This version of iMovie (10.0.7) allows you to add chapter markers

Are you're referring to this menu option?

If not can you provide a screenshot of this feature?

then share directly to iDVD.

Where do you see this in iMovie 10.0.7?  Screenshot?  Under the File ➙ Share menu there is not option to share with either iDVD or the Media Browser:

It turns out that iDVD recognized all of them, and there are 218!

Yes it does. How it does is to rename chapter 100 back to 1 and then again at 198, etc.  However, you will find that many DVD players will freeze or pause for a while at these transitions.  The pause can be minimized by burning at the slowest speed possible.

Follow this workflow to help assure the best qualty video DVD:

Once you have the project as you want it save it as a disk image via the File ➙ Save as Disk Image  menu option. This will separate the encoding process from the burn process.

 

To check the encoding mount the disk image, launch DVD Player and play it.  If it plays OK with DVD Player the encoding is good.

 

Then burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality.  Always use top quality media:  Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.

I stand corrected. I just opened iMovie and it appears that the version I have is 9.0.9! Further investigation shows that the update never happened, that an error occurred. Version 9.0.9 has a separate "Share" menu which includes iDVD:

Maybe I should keep the version I have... When finalizing the project, I'll burn the disk as you say so it works correctly. Thanks!

You don't want to use the Share ➙ iDVD menu option.  Use the Share ➙ Media Browser option as that produces a superior movie format for use with iDVD. 

Which resolution should I use? I know DVDs are only 480p...

Use 480p or Medium, whichever is offered.

This was the fix I was looking for.  Thank your the detailed explanation.
