If you are viewing the video on your computer, when the part of the video you want to save, hit the "PRTSC SYSRQ" key. This will save the screen shot to the computers clip-board. I don't know any way to save the screen shot as a pdf or JPG, but you can paste it into a word program sheet.Same guy, and same house. If I could figure out how to grab a screenshot from a video, I could share a picture of Bud with his plane in his driveway. His youngest(?) son, Dan, posted an appropriately-sappy video to a closed group on Facebook when the house sold after being their home for 61 years.
The best I have been able to do is then use your computers "Sniping Tool" to capture the screen shave in the word sheet and then you can save it as a jpg. You loose some resolution in the process, but it does work.
