Description

Plugin to Zoom, Pan & Rotate.

Requirements

• AviSynth 2.5.8, or 2.6.0 or greater
• Supported color formats: RGB32

Syntax and Parameters

Zoom (clip, string "srcx", string "srcy", string "dstx", string "dsty", string "factorX", string "factorY", string "angle", int "width", int "height", bool "show")

clip   =

Input clip.

string  srcx = ""

string  srcy = ""

The "center" coordinates in the original frame.

string  dstx = ""

string  dsty = ""

The center coordinates in the moved frame

string  factorX = ""

string  factorY = ""

The magnification factors.

string  angle = ""

The rotation angle in radian.

int  width = 0

int  height = 0

The new image dimensions.

bool  show = false

If true, it prints the calculated values on the image.

Examples

Sounds complicated? Not really, try this:

Version().ConverttoRGB32().zoom(dstx="n", angle="n/10")

Here you see that the variable "n" can be used to reference to the current frame number (and this is of course the most important thingie).

Or try:

Version().ConverttoRGB32()
zoom(factorx="n<41 ? pow((n+1)/41,0.5) : 1", factory="n<41 ? pow((n+1)/41,0.5) : 1", dstx="n<41 ? width/2 : width/2+5*(n-41)", angle="n<41 ? 3.1415*n/10 : 0")

And the new image gets a defined alpha layer (black=transparent, else opaque), so you can layer the result on top of another video.
