Does changing the fps change the speed of the animation? I had created animation in blender 2.76 with sound effects, at 30 fps, and rendered it at 60 fps. However, when I saw the rendered result, the video was faster than the sound. Does increasing the fps while rendering a video increase its speed? If yes, will simply rendering the animation at 30 fps solve the issue? If no, how should I solve this problem?
Generally, the keyframes (as the name indicates) of blender animations are based on frame numbers instead of absolute time. So if you render an animation that has been created with 30fps in mind at 60 fps, the video will be half the length.
If you really want it to be 60 fps and you do not want to redo the whole animation, you could make use of the &quot;time remapping&quot; parameter (https://docs.blender.org/manual/en/latest/render/output/settings.html), as described here for example: How to render an animation at a higher framerate?
