Were two fighter jets filmed escorting a saucer-shaped flying object over a mountain? No, that's not true: These special effects were computer generated. The video was originally uploaded to YouTube by the channel called oondyla. It has posted other special effects videos and includes a disclaimer on their channel that reads, "This channel is intended for entertainment purpose only. It shows how it could be IF ufo were real. Ufo are cgi generated image sequences."
The video titled, "INCREDIBLE UFO SIGHTING: TWO MILITARY JETS CONVOY - The Original Version!!!" was originally uploaded to YouTube on August 14, 2011. It was recently reposted on Facebook on July 24, 2022. The text captioning added to the video says:
UFO IN FLIGHT
In Plain Sight
With government jets escorting
This is how the post appeared at the time of writing:

Although the oondyla channel is currently forthcoming about their videos being CGI creations, this may not have always been the case. This video was debunked by Sixty Second Scams on August 12, 2015. At the 1:23 minute mark in the debunking video, an "Easter egg" is revealed -- oondyla has put a barely visible watermark of sorts, their name, on the sign at the side of the road. Below is a screenshot of that detail enhanced:
