site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com Thread-index: Acx9J7fvDlu1pYKp+Ei8bdka35vwjg== Thread-topic: Animation speed consistency in published title generators? User-agent: Microsoft-Entourage/12.24.0.100205 This may not be an high-end dev question, but I think it is relevant to those using Motion templates to make their FxPlug effects available in Final Cut Pro X. How do you create an effect that animates objects at a consistent speed - even if you change the duration of the title or clip the effect is applied to? I'm working on a Text Crawl title effect with a few extra features - mainly the ability to allow for any amount of text to crawl across the screen and clear the left-edge (as well as snapshots for FCP X's three main display aspect ratios). Whether I apply Rate parameter behaviour on the X co-ordinate, a Throw behaviour or Wind simulation behaviour to the text, the input values get scaled when the duration of the template is changed. This means users can't set all text crawls to have the same speed: the same values in different instances of the title effect will result in varying animation speeds. Although Avid generators have worked this way for many years, I've always thought this was an example of a programmers way of thinking about the problem disrupting the user model of how editing works. Does anyone know how to make animation speed independent of motion template instance duration? Alex PS: The current version is at http://www.alex4d.com/plugins/fcpX/Alex4D_Text_Crawl.zip _______________________________________________ Do not post admin requests to the list.
