These transitions allow one to show two video clips simultaneously in a single frame with variety of split shapes such as Vertical split, Horizontal split, Diagonal split, etc...

DOWNLOAD:

rehansplit.exe (34Kb)

Freeware Package contains 24 pre-built Split Video transitions.
If you like these please consider donating some amount to encourage me to work on more such freeware effects and transitions.

Installation instructions:

  1. Run the downloaded exe file and extract the xml file inside it. It should ask you to specify the AddOnTFX folder with a default value of "C:\Program Files\Movie Maker\Shared\AddOnTFX"

  2. Restart Movie Maker.

Usage:

To use this transition, place two clips on the Storyboard and apply one of these transitions in the middle. Change to Timeline view and drag the right hand clip towards left as far as possible without changing clip order.

Details of the Trick:

Split video effect is a name given to the the special effect achieved by showing two video clips simultaneously on the screen where a part of each clip is masked off in some manner to show the remaining part of the other clip. This is different from Picture in Picture effect in the sense that none of the clips change its size. 

In this package this effect is achieved by using the normal set of transitions that come with Movie Maker otherwise called DxtJpeg/SMPTE wipes. The trick is to freeze these wipe transitions in the middle using the undocumented Progress parameter.

For a normal transition (or effect), the Progress parameter is internally changed from 0.0 to 1.0 specifying the current progress value of the transition. But if we provide a specific value for this parameter via the xml file this constant value is used for the entire duration of the transition, effectively freezing the transition at that value.

For example consider the following two transitions which define the Vertical and Horizontal split video effects by specifying the parameter Progress to have the constant value of 0.5:

<TransitionDLL guid="{DE75D012-7A65-11D2-8CEA-00A0C9441E20}">

    <Transition name="SPLIT: Vertical" iconid="41">
        <Param name="MaskNum" value="1" />
        <Param name="Progress" value="0.5" />
    </Transition>

    <Transition name="SPLIT: Horizontal" iconid="40">
        <Param name="MaskNum" value="2" />
        <Param name="Progress" value="0.5" />
    </Transition>

</TransitionDLL> 

Many more interesting split transitions can easily be made by studying the parameters of the standard SMPTE wipe transitions, especially by using the external mask image.
