I've been using this for a long time for downloading of royalty-free content. I recently upgraded to pro-version to download in better quality and am very pleased with it.

The free version is great for everyday use, the pro version is excellent for higher quality work and also help support development..

Note to people upgrading: Make sure ALL your ad blockers and anti-tracking software white lists BOTH http://videodroid.org and https://videodroid.org. I thought it hadn't worked until I checked my (overkill) 4 different blockers.
