December UFO footage from East Anglia – genuine artifact or swamp gas?

This came across my feed and I wanted to get the Quirk Reports take on it before I dismiss it out of hand. Footage is about 40 seconds, taken on 15th December 2023 in Norfolk, early evening (around 5 PM when it was already dark, obviously). The video shows what appears to be a triangular object with lights moving in a way that definitely doesn't match conventional aircraft behaviour - jerky movements, sudden stops, changes of direction that would be impossible for normal planes.

What I've analysed so far: Video's shot on what looks like a mobile phone, fairly stable footage, no obvious signs of digital editing that I can spot. The object is consistent in size and brightness throughout, which rules out it being something close to the camera. The lighting on the object suggests self-luminous rather than reflected light.

The skeptic in me says: could be a drone, could be a weather balloon filmed at an odd angle, could be Chinese lanterns creating an optical illusion. But the movement patterns are genuinely unusual. Looking for thoughts from people who do actual video analysis rather than just armchair experts.

Upload the video or share a link. Can't give proper analysis without actually seeing it. Most "UFO footage" that gets passed around has artifacts or is deliberately misleading, but some is genuinely anomalous. The fact you're asking for proper analysis rather than just posting on Facebook is encouraging.

The triangular shape is interesting because military aircraft have right angles and symmetry. Natural or conventional objects don't usually look that deliberately geometric unless someone's built them that way intentionally. That said, geometry can be trick of light and perspective. Phone cameras are also notorious for creating artifacts at night. All the more reason to see the actual footage.

Norfolk's got some military history if I remember right. There's RAF bases and MOD testing areas. Could be secret defence project - our lot's got UAVs and experimental aircraft that look decidedly odd. Not saying it IS that, but it's worth considering before jumping to extra-terrestrial.

Here's the thing though: if we're talking about a tiny object far away, camera jitter and compression artifacts can make it LOOK like impossible movements when it's actually moving perfectly normally. Phone video compression especially plays hell with motion accuracy. Would need the original file to properly analyse.

15th December is interesting timing - winter solstice season. There's been correlations between anomalous activity and solar events. Not saying that proves anything but it's worth noting. If you've got the original file, get it analysed by someone with proper video forensics experience, not just UFO enthusiasts.
