on reddit the prevalent voice is that this is the best video ever, impossible to fake yadayadayada
their main argument is that the cloud illuminates during the flash and that this would be next to impossible to recreate with such detail.
adding a radial gradient around the flash does exactly that, as one user demonstrated:

there were also uploads almost 10 years ago with satellite data as an overlay, suggesting to be the
NROL-33 military satellite, which was launched on May 22, 2014 – later than the MH370 incident.
i also think the thermal coloration is not convincing for a military drone, which would be in black or white hot. however, someone could post process it manually (unlikely and for whatever reason but in the realm of possibility).
i personally am not sure if the thermal signature of the engine is accurate, it seems to be too cold?
the "portal" shows up as black on the thermal footage. i dont know how a portal would look like because i dont think anyone has ever seen one, but if the thermal is set to rainbow coloring, why would it show up as black and not red yellow or blue...?
edit: added screenshot part of the original footage that had the satellite letters visible in part
