How to make an object spin on its axis from slow to fast

[Stefan Cargoski]

Hi Community.

I have imported a PNG sequence of a logo spinning around 360, currnetly its just orbiting on its axis, and  I want to add some interest to it.

I'd like for the object to start of slow, and gradually build up speed, going faster and faster.

Can somoene please let me know a simple approach?

Thank you.

Thanks for reaching out.

To achieve this effect, you might want to explore keyframing the rotation property and adjusting the speed graph in the Graph Editor. This will allow you to control the acceleration of the spin. Here's a YouTube tutorial to get started: https://adobe.ly/4cRsfLt

Let me know if there are any other questions.

Thanks,

Thank you for your reply. 

But the PNG sequence already has a Rotation 360 spinning of the 3D logo. Adding rotation frames in after effects, makes the sequence lose the 3D, and becomes flat as it rotates. So I'll need another method.

Getting the logo to glow should be a case of adding the glow effect and keyframing the threshold.  

Getting the logo to speed up its rotation could be achieved using Time Remapping.

To enable, go to Layer > Time > Enable Time Remapping.

You'll get keyframes for the start and end of the sequcence and just like position or opacity keyframes, you can change the values to get it to speed up, slow down or go backwards.

That was it! Thats what I needed to make keyframes, and in the graph editor use the tangent handles to make it speed up and slow down.

Kind regards Cactus!
