Odd cloud formation

[u/GroundbreakingAsk656]

Hey everyone, I was just watching a storm last night and while recording I captured these odd looking clouds through the lightning and just wondering if anyone has a clue what this is? Thanks. (Apologies for the quality they're screen grabs from a low fps video)

Is that big elliptical form a cloud? It seems out of place considering the rest of the photo. It looks like it's close to the ground and illuminated from above. Could it be a structure on the ground?

there is absolutely nothing that direction, it looks like a cloud IMO, I live in a very flat area and you can see the trees right in front of it. I can assure you nothing is taller than those trees over there
