Animated Spline in Boris Red

[Peter Mcauley]

Hi,

You might first want to read through this tutorial, which explains how the spline masking system works in Boris RED. Then simply apply this knowledge to a filled spline shape that is used to generate a colored bar instead of a mask.

I hope this helps!

Cheers,

Hi Peter,

I’d created a long square spline. What I have is an L shape with no curve. But, how do you create the illusion that the line turns and curve? I know you can combine two spline objects by masking one into another and that is what I did.

However, I am not getting that curve illusion that you see on TV commercials. Whereas, your animated line moves across the screen up and down into another scene with a curve. Any video tutorials out there on how to create this spline effects?

Hi Jonathan,

To create the look that you have in mind, they these steps:

• create an “L” spline shape using the pen tool – leave it as an open 3-point spline shape
• set the track shape type to 3d extrusion
• in the control panel for the extrusion shape, set the fill to off and the border to on
• offset the angle by setting the spin parameter to 45 degrees

this will create the angular “L” ribbon shape – to animate it follow these steps

• with the track selected, select the pen tool again
• at the start of the timeline, set the bottom of the shape to it’s starting point by dragging the last point of the shape
• move to the end of the timeline
• reposition the point that you moved

now when you scrub the timeline, the shape will flow on.

If this in unclear please contact me (peterm@borisfx.com) and I’ll send you a small basic sample project that demonstrates this for you.

Cheers,

Peter.
