I have found Video DownloadHelper to be an excellent tool for my purposes--especially since it does so much for free--and even more once you buy a license. I can archive online video clips before they are deleted or paywalled. I can download video from one platform and then share it (or edit and share it) on another platform. Very helpful. I probably use it a dozen or more times a week--sometimes a dozen or more times a day. Excellent program.
