Re: [Avid-L2] Re: Sapphire question

 

Here's the HTML Help from Sapphire Pan&Zoom:

 

S_PanAndZoom

Loads a still image from a file and pans, zooms, or rotates it in three dimensions, while preserving the original resolution. To get started, click the Load File button and choose an image. Supported formats include JPEG, PNG, TIFF, and EXR.. Then adjust the parameters such as Shift, Zoom, and Rotate to position the image, and set keyframes to create movement.

In the Sapphire Distort category.


Inputs:

Background:  The current track.   The clip to use as background. The output of the effect is composited over this clip.
        

Parameters:

Load Preset:   Push-button.
Brings up the Preset Browser to browse all available presets for this effect.

Save Preset:   Push-button.
Brings up the Preset Save dialog to save a preset for this effect.

Load File:   Push-button.
Loads an image file. This file will be read from its original location each time your project is opened or rendered. If you move the file, or move your project to a different machine, the file will have to be re-loaded before it can be rendered.

Zoom:   Default: 1,  Range: 0.01 or greater.
Zooms in or out on the image. Values less than 1.0 move it farther away and make it smaller. Values greater than 1.0 move the image closer and enlarge it. This parameter can be adjusted using the Shift Widget.

Scale:   X & Y,   Default: [1 1],  Range: any.
Adjusts the horizontal and vertical scale of the image independently. Use this to stretch the image or change its aspect ratio. This parameter can be adjusted using the Shift Widget.

Rotate:   Default: 0,  Range: any.
Rotates the source image by the specified angle in counter-clockwise degrees.

Shift:   X & Y,   Default: [0 0],  Range: any.
Translates the source image. This parameter can be adjusted using the Shift Widget.

Swivel:   Default: 0,  Range: any.
Rotates the image left or right in 3D about the vertical axis.

Tilt:   Default: 0,  Range: any.
Rotates the image up or down in 3D about the horizontal axis. You can use Swivel and Tilt together to rotate about arbitrary diagonal axes.

Perspective Amount:   Default: 1,  Range: 0.25 to 4.
Controls the amount of lens telescoping while applying Swivel and Tilt. Increase for more 3D perspective.

Shear:   X & Y,   Default: [0 0],  Range: any.
Shears the source image horizontally or vertically.

Scale Lights:   Default: 1,  Range: 0 or greater.
Scales the result by this value. Increase for a brighter result.

Offset Darks:   Default: 0,  Range: any.
Adds this gray value to the darker regions of the result. This can be negative to increase contrast.

Combine:   Popup menu,  Default: Foreground Only.
Determines how the image is combined with the background. 
Over:  The image is composited over the background. 
Foreground Only:  The background is ignored and only the image is shown. 

Wrap:   X & Y,  Popup menu,  Default: [No No].
Determines the method for accessing outside the borders of the source image. 
No:  gives black beyond the borders. 
Tile:  repeats a copy of the image. 
Reflect:  repeats a mirrored copy. Edges are often less visible with this method. 

Filter:   Check-box,  Default: on.
If enabled, the image is adaptively filtered when it is resampled.. This gives a better quality result when parts of the image are warped smaller.

Crop Left:   Default: 0,  Range: 0 to 100.
Crops the left side of the input image.

Crop Right:   Default: 100,  Range: 0 to 100.
Crops the right side of the input image.

Crop Top:   Default: 0,  Range: 0 to 100.
Crops the top of the input image.

Crop Bottom:   Default: 100,  Range: 0 to 100.
Crops the bottom of the input image.

Vignette Parameters:

Vignette Darkness:   Default: 0,  Range: 0 to 1.
Vignetting is darkening of the image towards the corners and sides of the image. This parameter controls how much the outer corners of the screen should be darkened (vignetted). 0 gives no vignetting, 1 gives maximum darkening.

Vignette Radius:   Default: 1,  Range: 0 or greater.
Distance from the center where the vignetting starts.

Vignette Center:   X & Y,   Default: [0 0],  Range: any.
Adjusts the center of the vignette ellipse.

Vignette Edge Softness:   Default: 0.5,  Range: 0 or greater.
The width of the vignette's soft edge. Larger values give softer, less visible edges.

Vignette Rel Height:   Default: 1,  Range: 0.1 or greater.
Controls the aspect ratio of the vignette ellipse.

Drop Shadow Parameters:

Shadow Opacity:   Default: 0,  Range: 0 or greater.
The opacity of the drop shadow. Use values near 0 for subtle transparent shadows, or values near 1.0 for stronger shadows.

Shadow Shift:   X & Y,  Default: screen lower right.
The horizontal and vertical offset of the shadow.

Color:   Default rgb: [0 0 0].
Scales the color of the result. For example, if it is yellow [1 1 0], the blue of the result will be 0.

Blur Shadow:   Default: 0.1,  Range: 0 or greater.
Determines the softness of the shadow.

IIRC correctly, using Shift>Alt and dragging would create a "pseudo" X or Y rotation, which was really more of a 2D skew than a rotation.  I've been away from StageTools for quite a while, so I may not have the exact combination of modifiers correct, but you get the idea.

Our director of post told me that Sapphire has added Pan and Zoom to it's toolset, but I can't find it on the website.  I've asked her to send me a link for an evaluation copy.
Will keep the L-2 updated at to what I find out.
