On all the blu-ray/AVCHD disks I've ever created (with full HD content), the menu thumbnails have black bars at the top and bottom.
However, my latest disk has a mixture of thumbnails with black bars, and some without (i.e. full picture thumbnail).
On the preview, all the thumbnails have bars.
I've not done anything different from previous projects - is this another random bug I've discovered?!?
Anybody else experienced this?
This happens when you project settings do not match your source video specs.
What model of camcorder is your video coming from and what format and resolution is it?
Which project settings did you select when you first started your project? You can see, but can not change, your project settings under the Edit menu.
Also make sure that menu templates you select have a little HD logo in the upper right corner. HD menus are 16:9 while standard DV menus are 4:3.
