Do either of them help?

The red outline means that the item overlaps another nearby item, and I’d guess the solid red square is the extent of the overlap.

Unfortunately, this can’t be solved in Encore.

What Encore actually does is split your motion menu clip into two parts at the loop point. It then causes the intro part to play once, and the rest to repeat. Audio and video breaks occur (depending on the player hardware) at the start of the repeating part, because the player has to preload the menu at that point, and that takes noticeable time. This also means your audio will restart at the loop point, rather than continuing to play on its existing timeline.

This is all because of a flaw (my word) in the Blu-ray spec that prevents a simple delay in the start timing of a menu. There are more complicated Blu-ray mechanisms that I believe will achieve the desired effect, but Encore and most authoring software doesn’t support them.

I’ve seen evidence that some versions of DVDArchitect support menu video loops with a non-zero loop point, but in Encore I think you’re out of luck.

In answer to your original question, FWIW, the instructions for installing Encore are here:

It’s not pretty.

My guess is that each clip has a separately muxed menu stream (i.e. an IG elementary stream in a different M2TS file). In that case, the player may pause while it tries to pre-load the menu, since players are not required to be able to play from multiple files simultaneously, and I think the video will be black while this happens.

I can’t think of an easy way to fix it, other than re-authoring to force the menu stream to be muxed in with the video stream.

[Robin Henson]

You can’t, really. The video stream in the m4v file needs to be multiplexed into a MPEG-2 transport stream file (and the audio would usually be multiplexed in there too), then you’d also need a clip info file to go with the transport stream, along with a playlist file, plus Index.bdmv and MovieObjects.bdmv files for the disc as a whole.

Blu-ray has its middleware pretty firmly entrenched in the workflow.

It’s not quite so severe a Blu-ray limitation as such. Menu pages use an 8-bit indexed color table, and every page (whether regular menu or popup) can in theory have a different color table.

I think you’re running into a combination of two problems:

— Encore is trying to be clever, but isn’t succeeding very well. (It looks like it’s trying to unify color tables across pages.)

— You are testing the limits of what’s feasible with 256 colors. Each of your thumbnails has its own range of hues, and both the thumbnails and the text rely on gradients and glows over a reasonably large area (that is, more than just anti-aliasing along edges).

You might have better luck if you go back to your image editing application, and force all your images all to use the same 8-bit color palette. That might ease Encore’s task, and it will give you an idea of what’s feasible and what’s not.
