- I sat down in front of an Amiga 2000 with a video toaster for
- the first time last night with the intention of figuring out
- how to subtitle. I was able to generate exactly what I wanted
- using the toaster and script editor, with one small problem.
-
- Here's what I did:
-
- I created a project with a character book containing my sample
- titles. I used the Alt-F9 option to pre-render each of these
- overlays.
-
- Then I went into the script editor and displayed the titles
- using a sequence of the following commands:
-
- WAIT Pause before title appears.
- PAGE 01 Load a CG page.
- TAKE Slap it up on the screen as fast as possible.
- PAGE 02 Begin loading next CG page.
- WAIT Wait for as long as the first title should
- remain on the screen.
- TAKE Slap the second title up on the screen.
-
- This was to display titles with no titleless gap in between.
- (I think I have the command names right, but bear with me.)
-
- Here is my problem. Apparently, even though each of my CG
- pages was pre-rendered, the toaster still takes a minimum of
- about 3 seconds on the "load CG page" command. Since often I
- want titles to be on-screen for only 1.5 to 2 seconds, this
- causes a considerable problem.
-
- I thought since I had pre-rendered the CG pages that their
- loading should be almost instantaneous? I thought about
- loading the CG pages into fram buffers before starting the
- titling script to see if that would be faster, but by that
- point it was too early in the morning and I couldn't figure
- out how to do it.
-
- Does anyone out there have experience with subtitling using
- a toaster, or can simply tell me what I am doing wrong / if
- I am just out of luck?
-
- Please reply via email. Thanks,
- Kevin
