First .. I am no expert, I took Barbelmicks advice on how to post vids when I joined the forum . Ta Mick. ( I did say you had started something at the time..sorry

)
Here is how I do it on a Chromebook ( different devices may be different , but anything running the chrome browser should be near it

)
Select your vid
alt+right click
Select copy URL
In the text of the post ctrl +v to insert the vid
It doesn't always work, for some reason, maybe the vid doesn't allow it, but mostly does.
See if I have that right ....
Yep
Ho Hum
