When I post a video,I just go to photobucket,then my library ,then I click on the video that I want to share to bring it to the main screen .
On the right side I click on the direct link which automatically copy the link on the browser,then come here to where I'm doing the post and RIGHT CLICK on
the screen and paste it
COPY and PASTE wick the mouse Right Click.
You can try it by making a post ,preview it ,and if is not something you like ,then edit your post and remove the content of it .
Hope this make sense .
It's not rocket science (I can't post a video here right now,because at this moment photobucket is doing a maintenance of their web site )
