I wouldn’t bother, looks like an industrial estate so your in their domain, swimming with sharks, I wouldn’t expect anything less, it’s not like they can give you a wide berth.
The road was perfectly wide enough – they could have moved further across although obviously that might have meant the second truck waiting for the oncoming vehicle so he could safely pass the obstruction on his side of the road.
The good news – both clearly saw you and moved over, albeit not by as much as you would hope. In fairness you were stationary so the risk of you wobbling in front of him was lower (although I’ve had the odd spd moment that would have been very messy!). I personally wouldn’t do anything about the opex.co.uk one, the https://www.howelrichards.co.uk/ one looked like it was a bit more stupid – there’s contact details for them on their website so you could contact them direct to express your concern – but don’t be surprised if they don’t care. They do say they have detailed tracking on every vehicle so they should be able to corroborate your timestamp on the video.
Personally I wouldn’t both reporting to the police with a dodgy timestamped video as whilst its explainable with your own evidence it would be an excuse to find “potential doubt” and therefore not have sufficient evidence of a prosecution. The fact there were two of you helps your evidence too – but does the other rider care as much? ie. could they be bothered spending a whole day sitting around a court probably 12 months from now waiting to give 20 minutes of evidence to say “yes a truck passed me, no i didn’t note the number plate at the time but read it off the video, no I couldn’t see the driver, at its closest I was 50 cm from it, I was intimidated by it, it was doing more than 20 mph, no i’m not an expert in estimating speed but I’ve been driving and riding bikes for years, yes we were pulled over at the side of the road, no we didn’t stop suddenly, and umpteen other seemingly dumb questions”. 90+% chance it wouldn’t go to court/trial but no point reporting unless you can be bothered with the inconvenience to back up the video.
