I rendered my animation in 30FPS then found it hard to match the narrative exactly.
So I like to speed up some parts and slow down others, then I need enough frames to do so. So now I like to re-render every scene in a higher frame rate, from the original 30 FPS to 60 FPS.
But I have a lot of keyframes in every scene, so I wonder if there is any magic button that can make the keyframes know where they should be after I increase FPS to 60.
Edit 1 day after:
What I want to know really is how to move the keyframe to its position after I increase the frame FPS to 60, then I found a simple solution, select everything in the scene and move to the timeline and scale all keyframes 2 times.
I am making a machine visualization, the scene is heavy and there are many keyframes in the timeline - something for curve animation, something for shader mixing, and of course many transformations, I am not sure if my method(SX2) can conclude every keyframe.
