Scenarist SD - "buttons over video" - how to do?

[neil wilkes]

How would I go about creating a "buttons over video" effect in Scenarist SD?
The manual & PDF documents are silent on the subject but I know it can be done - just a case of "how"?

BOV is a standard "highlight". So you do a subpicture at a specifiec timecode and then you draw the rectangle as a selection and adds a button command.

I tried this but got an error telling me there was no properly formatted subpicture (it was a regular indexed TIF, black on white).
What I am trying to do is overlay a button set for the duration of the entire timeline.....it would need to be active constantly, but the manual (and my PDF from Sonic Support) is at the kindest a tad vague.

Maybe try a 4 Bit Bitmap instead of TIFF.

Maybe the highlight Bitmap needs to be 720x573 because a subpic in general is not allowed to occupy all 576 lines (it's because the analogue half lines at the top and bottom shall never contain any content).

Interesting - never had to use anything except 720x480 NTSC TIF before so the idea of a BMP did not occur to me - why would this make a difference?
The Sonic "instructions" such as they are mention only using buttons on subtitle scripts, whereas I am trying to use a button over video but dragging in the button overlays that work in Menu tracks simply doesn't work for me.
It's pilot error of course - I just do not know how to do this

Well, I wish I could help you but I never used Scenarist. With most authoring softwares I've used a BOV works by placing a button highlight point on the timeline (very similar to placing a chapter point manually) where the button should appear and then adding a single subpic where you would usually place/import the subtitles of a titleset.

NTSC subpics are not allowed to exceed 720x478. Authoring softwares usually crop 2 lines by themselves but maybe this doesn't happen with BOVs?
