After spending a little bit of time on figuring out how to set up MFD exports in DCS, and a couple of sorties in very simple SP missions made in 2 minutes, i've got 6 short clips of radar in operation
They look a little odd without context of what is going on, with only the artificial horizon at the bottom adding some clues whenever there is no lock, but its what you've asked for, so i hope it works for you!
Included:
-Peace time intercept with a tanker
-2 clips of war time interdiction of an Su-24
-2 clips of a 1v1 dogfight Mirage F1 vs F-4 Phantom
-1v2 dogfight Mirage F1 vs F-4 Phantom
Here's a playlist on youtube, feel free to download and transform these videos any way you wish
If you would like raw video files, i can upload them to a google drive, just that this is simpler
I could also fly a longer mission if you like, with contacts popping up on radar without getting engaged etc. That recording would probably reach about an hour or two in length, just wasn't sure if this format would work for you.
If for any reason this is not usable, let me know and we'll try to work something out, see how to fix etc
Its also worth noting that this was recorded before the radar rework, so the behavior may not be super accurate
Ps. I didnt know your setup exactly, so i decided to not crop the video and upload the raw capture. This means you'll likely have to center the image and probably crop out the OBS moments at the beginning and end, but i hope you can figure that out!
