- I'm having a bitch of a time trying to get a captured piece of
- video composited with a logo animation done in Lightwave,
- using alphachanneling in ADPro/Fred.
-
- What I have is:
-
- - a sequence of captured video (captured using the Personal
- Animation Recorder, then saved as 24 bits iff's);
-
- - a sequence of a flying logo done in Lightwave, also saved as
- 24 bits iff's;
-
- - a sequence of the alpha channel, generated by Lightwave, for
- the flying logo sequence.
-
- Now I want to do an overlay of the second sequence on the
- first sequence, using the alpha's from the third sequence.
- Manually this goes allright, using the compositing feature of
- ADPro, but to do this for 250 images I'd have to be insane.
- Therefore, I tried to achieve this using Fred. I set up the
- three different sequence files, saved them as .seq's, then
- started up AnimOps/Compositor.
- As sequence 1 of 2 I defined the video sequence, using
- 'transparent color' settings R:-1, G:0, B:0 and the 'mix from'
- settings 0,0. I set the inframe, duration, skip and offset
- correctly.
- As sequence 2 of 2 I defined the logo sequence, using the
- alphaLogo sequence as the alpha channel to be used. Doing this
- resulted in the 'transparent color' and the 'mix from' fields
- getting ghosted. Here also inframe, duration, skip and offset
- as they should be.
- As loaders I selected universal for both.
- I set up the results panel as usual, just setting the output
- sequence and the image root name. Also here the correct number
- of total frames, skip frames and process frames.
-
- Now I thought everything would go alright, but to my surprise,
- the only thing that happened was that AdPRo loaded an image
- from the video sequence and then saved it under a new name.
- I experimented with the 'mix from' settings, but this had no
- possitive effect.
-
- Someone please help, I'm going nuts...
-
- Thanx,
-
