Strange object passing in front of Mars #shorts

Heads up I'm resurrecting this clip from 2018 in order to get more subs and because its quite fun. I personally think the object is a party balloon that has somehow managed to rise very high up into the atmosphere without popping but I don't know for sure.

Here are details of the capture:
Date 1st Sept 2018 Time: 20.55.20 GMT
location: North London 51 34' 53" N -0 06' 17" W
The video is shooting at 100fps and the frame size in 320x280. This is pretty standard for planetary imaging.

Here is my investigation on what I think the object is: https://youtu.be/7_CgfM6yN78
