I am out of ideas. I cannot copy and paste this clip onto the same sequence. When I do, they are different sizes on the timeline. They are NOT different lengths, the duration of both is the same, the speed is 100% on both, so that rules that out. I also cannot simply cut one down to the same size as the other, as it only lets me cut on the frames, which this clip falls between frames for some reason. I have asked many people and am out of ideas for how to remedy this, and how to prevent it in the future. Any help would be my absolute angel.
