![]() ![]() ![]() You can use these interpolation methods to provide a more natural progression between sets of valuesa smoothness that would be harder to achieve with simple division and multiplication. These styles work exactly like their identically-named keyframe interpolation styles (available via the Animation->Keyframe Assistant menu). The interpolation methods clamp their incoming and output values at theĪnother difference is that you can specify different styles of interpolation: ease(), ease_in() and ease_out(). Hand-rolled 'divide by 5, multiply by 360' technique we used earlier. This is a chief difference between these methods and the If you try this, notice that the layer stops rotatingĪt 5 seconds. ![]() In English, this expression would read something like: 'as time goes from 0 to 5, output values from 0 to 360, with linear interpolation.' Applied to a layer's rotation parameter, this expression would cause the layer to rotate 360 degrees over the first five seconds of the comp. To see how these arguments work together, consider this example: Value2 can be a number or vectorif it doesn't have the same dimension as value1, After Effects will ignore components or append values of 1, as necessary. When t equals or exceeds t_max, the method will output value2. Value1 can be a number or a vectorthe results will have the same dimension as value1. When t equals or is less than t_min, the method will output value1. T_max The maximum expected value for 't'. Optionalif t_min and t_max are omitted, After Effects will assume values of 0 and 1, respectively. T_min The minimum expected value for 't'. The values from t must be numbers (dimension of 1). 'rotation', 'time', or a variable of your choice. These methods look more complicated than they really are, mostly because they accept so many arguments. ![]()
