Hi hagatha and Draclvr, when you Stop the video, at the very bottom right of the video screen you will see a small picture frame and if you Hover your mouse over it, it will say Camera Roll, click on it and another screen pops up, then click on the 3 dots on the Top Right of the Screen and then click on Open Folder and it will bring you to the Video(s) you just made, oh I almost forgot, when you Stop the Video it automatically saves the video.
I hope I explained this OK, my writing is not the best.
