This tutorial provides information on the application and adjustment of a Sparkle filter in relation to a selected image (or clip) in Vitascene. The use of Key frames is also discussed here. To do this, for example, Sparkle rays are presented as an animation in the background image (set in motion).
First start Vitascene, then go to the Filter Templates and select the Sparkle filter (e.g. Effect #131) by double clicking in the Vitascene preview window.
Should you be running Vitascene in a stand-alone format, after saving the effect, the desired background will no longer be visible in the preview window (but rather an example image). To import our image, go to the Navigation Menu in the Source field and click on the Video A option.
This opens the Video A dialogue box. In the Source field click on the Type of fill option, this opens a drop-down menu; select the Image / animation option.
Then click on the Folder button - to the right next to the Image drop-down menu - to select our image file, for example, and import the file with the help of the Image option. The image file appears immediately in the Vitascene preview window (with the Sparkle filter already integrated).
The Video A dialogue box also contains setting options for imported images (or clips) for pixel-aspect, attributes and geometry.
For this workshop, use the original image without additional settings.
Now go to the Navigation menu and click on the Filter-Presets option.
This opens the Filter-Presets dialogue box with various templates and settings for the active Sparkle filter.
Now go to the Navigation menu in the Parameter field and click on the Filter option.
This opens the Filter dialogue box with various settings for the active Sparkle filter (without filter templates, since a template is already applied in the preview window).
Here you can modify the settings for the Sparkle filter, but first go to the preview window and check whether the Keyframes option is activated (key points during the course of an animation, which have various properties at pre-determined times).
Without activation of the Keyframes option no changes in the effect, in relation to the progress of an animation, will be shown. In this case, the settings will apply to all points in time during an animation.
Now stop the preview by clicking on stop. Leave the beginning Key frame with its current settings (see preview or current controller position). Next, move the slider to a new position during the course of an animation. No new Key frames will be placed, unless you enter the first setting in the Sparkle dialogue box, in relation to the current position in the Timeline.
Now alter the following settings using the controller:
Glow-Intensity = 70%
Spot-Intensity = 0%
Orientation = 60%
and reduce flicker = 54%
This will create the following preview for the 2nd Key frame. Start the preview to look at the effect with the help of the Play button.
Now stop the preview by clicking on stop. Now move the slider to a new position during the course of an animation. No new Key frames will be placed, unless you enter the first setting in the Sparkle dialogue box, in relation to th
e current position in the Timeline.
Now alter the following settings using the controller:
Length = 25
Erosion-Threshold = 91%
Glow-Intensity = 70%
Spot-Intensity = 0%
Orientation = 80%
and reduce flicker = 30%
This will create the following preview for the 3. Key frame. Start the preview to look at the effect with the help of the Play button.
Now stop the preview by clicking on stop. Now move the slider to the end position during the course of an animation.
Now alter the following settings using the controller:
Length = 20
Highlight-Threshold = 20%
Erosion-Threshold = 13%
Glow-Intensity = 30%
Spot-Intensity = 0%
Orientation = 90%
and reduce flicker = 20%
This will create the following preview for the End-Key frame. Start the preview to look at the effect with the help of the Play button.
Now stop the preview by clicking on stop.
Now you can process the animation as a video clip in preview, with the help of Export.
Note:
Naturally, you can shift Key frames within the Timeline, to do this place your mouse on a Key frame, hold down the left mouse button and drag it to a new position in the Timeline. You can also delete Key frames during the course of an animation, to do this place the slider on the corresponding Key frame and press the Delete key on your keyboard.
This completes application of the Sparkle filter in connection with the use of Key frames in the Timeline.
