Hello.
We hace a project in wich the user play a movie of a travel around the earth. While the movie is playing the user can see detail of a country. To do this the user push the OK button on te remote. To do this movie we use TFDVDEdit to insert 170 cell in the movie. In each cell there navpack with button. This process work well.
When the user choose a country, we have to display a collection of still picture. The user use the remote to navigate in the picture and to come back to the earth navigation. If you calculate the number of stills (8 stills *170)=1360. To do this we decide to use the same process that we use in the earth navigation. But in the earth navigatiion there is no stop. In the still picture we need to make a loop, because the user can choose some action. To do this we make a test. in this test we place a cell command in the PGC (Link Cell2) and in the cell 2 we call the cell command. But there is a flsh with the button. Keep in mind that we do not use the VTSM. We use this process because it is more easy to produce a movie with all of the still . Is there a solution to avoid the flicking effect in the link cell???

thank you

The flicking appear on the Apple DVD Player.

Unfortunately, LIBEO, a non seamless situation arises when you have a cell command. This causes the sub picture not to display briefly. Same thing happens on motion menus at the loop point.

Anything that we don't want to flicker at these locations has to be a part of the video (the last frame of the video will be paused momentarily at this point, too, just so you know).

Take care,

Trai

Hi Trai,

So, our solution is bad. Do you know how many menus we can have on DVD Spec. The solution is to transfer our still picture from the VTS to VTSM and display it as menu. But this take 1360 differents menu.

Hi LIBEO,

You can have thousands of PGCs in a VTSM domain. You would probably go over the 1 gig limit per menu domain, before you reached any theoretical limit, which is around 32,000 some odd (I wouldn't approach that number though).

Take care,

Trai

Hi Libeo,

1) Could you use the "Cell Still Time" property instead of a cell-command ? If you set it to 256, this will freeze the final frame of the cell.

2) Alternatively, how about rendering the stills with a copy of the button highlight included in the video ? That way even if the button disappears briefly when the cell loops you shouldn't see it.

3) If I understand you correctly, you are adding cells to the "world animation" in TFDVDEdit after muxing ? Be careful that none of the button highlights cross these cells, since I believe this is out-of-spec and will cause issues in some players.

Good luck,

Cheers

Hi Trai and Ian

I will try all of your solutions to choose the correct for my project.
To produce many menu what is the best tool. DO you think DVDSP can handle 1500 menu or do i have to use another solutions.

Can i create menu in tfdvdedit using data in a VTS. ?? I hope my question is clear.
