From the
main videos menu item you can see video links such as:
https://peakfun.com/video/videos/1-mount-jefferson?from=listing
It should theoretically be:
https://peakfun.com/video/1-mount-jefferson
A few reasons:
1. It's shorter
2. Redundant usage of "video" in the URL
3. Prevent duplicate entries in search engines
As for the parameter, it's not needed. The recommended URL type works as is as seen in the second link.
