Currently there is no way to change time of last video view without changing time of all animation
Please make last view works the same as others ( with possibility to change it length ) and make length of all video as separate option.
Well, that’s just the last frame you are selecting, so If you want that to stay still more time you just have to add another final frame and give the previous one the duration you want. The green number you are marking its as you know the total video length, so it will never add more seconds to the final frame because its the ending point. Some ppl will get confused by the number position meaning different thing.
