I am working on a video which includes some dropped frames ever so often. When a frame dropped, it repeated the previous frame sometimes 2 or 3 times. I am overlaying many objects on this video, and the problem is that when interpolating a property, it continues to interpolate during the dropped frames, meaning the objects move while the video remains still. Because of the huge amount of objects in my scene (100+) it is incredibly tedious to go through each and find each dropped frame, set a keyframe for the properties, and copy them for all the repetitions of that frame. Is there a way to either set a keyframe for all properties at some time, or ideally to set time ranges for the whole composition where interpolation is disabled?
