Contamination or too much gelatin?

[Exortus]

Hello, I bottled my last batch of brown porter last sunday, everything looked fine inside the fermenter, I mean, there was no weird looks or smell, the taste was pretty good as well.
Today I took one bottle to take a look and noticed a strange body near the surface of the beer. I have never seen that in my previous batches, so I'm a little bit concerned.
I've done some research and I suspect of two things, either I used too much gelatin to clarify or this is dextran due to low quality primming sugar (shame on me).
I also suspected of pediococcus at first, but since the beer isn't thick I discarded that possibility.
So, have anyone ever seen that before? Any thoughts?

Are all bottles like that? I had gelatin effect the lower part of my bottles before, it looked like floating hop debris or something, not really sure how to explain it.

Not all of them, I'd say 70%.

I see, never seen it before frankly. But if it tasted ok i would drink it anyway lol And you never know maybe if you put them in the fridge for a week it might drop to the bottom.

Looks like a mixture of gelatin and priming sugar. Tell me you did not boil the gelatin, though. You just heated it up to 150-160 degrees.

I recently had a similar thing happen. I have been searching the internet and your photo is very close to what is in my gallon of chestnut beer. After adding gelatin a little blob with ropy strings, like a jellyfish, appeared floating on top of the beer. I decided to wait a couple weeks and it eventually dropped to the bottom. I have now bottled it being careful not to disturb it. I am hoping that it's just a blob of protein from hastily adding too much gelatin (and possibly doing the procedure wrong). I will try the beer out in a couple weeks and see if there are any ill effects

Here's a video of it after bottling:
