Once you’ve located your final frame, you need to generate the parameters for each of the keyframes in your movie. If you’ve paid for whoosh you can use the UPR tool to do this with Ultra Fractal parameters; save the resulting .upr file and render it as a batch to produce all the keyframes at once. Note you should still follow the Rendering Images instructions below.
Without Using the UPR Tool
If you are using the free version of whoosh, you will need to generate the parameters for these keyframes yourself. Each keyframe’s magnification is exactly one-half of the following frame’s magnification. So, starting from the last frame, divide the magnification by two and then save the parameters with a different name. Keep dividing by two until you reach the beginning. Note that if you have a multi-layer fractal you will need to change the magnification on each layer.
Ultra Fractal can help you somewhat with generating these parameters (but the UPR tool is easier). You can use the Zoom Out option on the Fractal menu (or press F10) to zoom out exactly 2:1. You will need to do this to produce each keyframe. Note that this will not work if you’ve changed the default zoom ratio in your preferences to something other than 2×.
Rendering Images
Once you have created your parameters for each keyframe, you need to render them. If you’ve put them all in the same .upr file, Ultra Fractal can render them all at once for you. Open the parameter browser (CTRL+B) and select the UPR file itself in the left panel; right-click on it and choose Render to Disk. Choose appropriate options and then click OK.
Whatever method you use, you will need to name your keyframes consistently for whoosh to be able to load them properly. Follow these guidelines:
- Use the same base name (e.g. “zoom”).
- Append a frame number. All frames should have the same number of digits. If you’re using the free version of whoosh, you must start your frame numbers at 1.
- Use the standard
.jpgextension. (Note: your version of Windows may be configured to hide this from you. This is one of Microsoft’s biggest security blunders, but that is a topic for another day. You just need to make sure the file really does end in.jpgwhen it ends up on your web site.)
The UPR tool will take care of the naming conventions for you automatically.
