How to manually handle interpolation between 2 keyframe?

[jérômel65546684]

Hello,

I am currently working on a plugin that apply rotation (according to yaw, pitch and roll angles) to a video.

I'd like to know if it is possible to control the interpolation of those 3 angles between 2 keyframes (other than linear, bezier etc...) or manually adding some intermediate points to control the trajectory?

Thx in advance

No additional control of keyframe interpolation is available, via any PPro API.

Using the AE effect API, with an arbitrary parameter data type, you could control your own interpolation (see PF_Arbitrary_INTERP_FUNC).  You could try using such a parameter type in combination with an angle UI control.
