Video Bitrate too High? Please help me fix it!

Is Create Disk the application not responding? Were you outputting to Hard Drive to make a Disk Image, or directly to a DVD burner?

I was able to make a DVD without problem of your test movie.

Step 1: Create a new project: SD 720x480 Anamorphic (the original is widescreen) and frame rate 29.97.

Step 2: add media to project storyline

Step 3: Share to DVD

Open the Settings tab and set Output Device: Hard Drive.

No problems.

The output is a *.img file (disk image).

I think you can just use Disk Utility to burn the disk image to DVD. I think I'd be inclined to recommend Toast as a better disc burner.

If you try to go directly to DVD, then you're "pushing" a lot of data at the disc recorder which is trying to burn the data "in real time". It's not like saving files to a hard drive. DVD is notorious for disc buffer underruns and overruns (they have to receive data at a specific rate.) In that case, it's more important to keep the data rate between 5 and 8MB/sec (which is the maximum data rate the DVD standard allows.) Burning a DVD like a data disk (image copy) is a lot easier for software and burners to handle, it's more reliable.

Disk Utility does not write or create video DVDs, it copies the raw data from an image to a writable DVD. There is no capacity for it to do menus etc. FCPX creates the menus when you export (share) the project (or attempt to burn directly to DVD media.)

The settings I used saved your project to HD as a "disc image" containing the DVD formatting required. You can double click on the resulting .img file to mount the DVD "disc" in the Finder and play the "DVD" (image) with DVD Player (should be in the Applications folder) to test it before committing it to a disc.

What you need to do is a simple "data copy" of the image to a DVD disc. The most compatible DVD discs are DVD-R. The most reliable software is probably Toast Titanium by Roxio, but not a necessary requirement.
