Exotic Fade
(Version 1.0 beta 5)

This filter is based on the Image Zoom 1.2 source files by Donald Graft.

[Place this text file in the VirtualDub plugins directory to make it available via the Help button on the filter configuration dialog box. The computer must have an HTML browser, such as Internet Explorer or Netscape, available in its search path.]

With this filter you will be able to fade two avi file using various effects (dissolvence, left pan, right pan, top pan, bottom pan).

Preliminary

First you have to copy "ExoticFade.vdf" and "ExoticFade.html" (this guide) files in the plugins directory under the VirtualDub main directory. Now you are ready to use the filter. Note that the filter create a "temp" directory under the VirtualDub path where saving the buffered raw bitmaps.

Usage

This filter work in two pass. In the first pass all the frames involved in the fading are buffered; in the second pass the dissolvence is done. You have to load the first avi file; then load the second avi file with "append avi segment". Now load the filter and take a look at the "configuration options"

The Configuration Options

Used frames This value indicate the number of frame that are used in the fade. For example if you select "5", the first five frames of the second video and the last five frames of the first video will be used for the fading process.

Base frame When you merge two avi file, you will have one more long file. This value indicate the number of the last frame before the strat of the second avi file. For example, if first avi file is long 100 frame (0 to 99) and the second is long 50 frames (0 to 49) when you append the secon you will have an avi long 150 frames (0 to 149). The base frame will be 99.

Fade mode Fade mode indicate the kind of the fading. It may be "fading", "left", "right", "top", "bottom" for fading, "disabled" for disabling the function.

End preload, do fade With this check leaved unchecked the filter will bufferize the frames involved in the fading process. For example if you select 5 as used frames and 99 as base frame, the frames involved will be 95, 96, 97, 98, 99 (first video), 100, 101, 102, 103, 104 (second video). You will have to play throught frames 95 to 104 to do the first pass; you will notice that for each frame the destination screen will be green (this indicate that the filter has correctly buffered the frame); if you will have a red one then the filter has not been able to bufferize the frame). With this checked you will perform the fading.
