My problem is that line on the 3/4 of the vid. To help to understand what i've done i post a pic about it:

i used this masking thing befora, but no problem appeared, so i don't have any idea how to fix it.
Any ideas?

I think its because of the clouds else I don't have any ideas cause i suck at editing

there are no clouds.I did the mask because i wanted to make the sky fully white.

try to make the feather type: both and make it like 5%
oh and your biggest problem isnt the line - its the building bug at 00:10 and I think you can fix both with chroma keyer

By the way change your FPS to 30 and the resolution to the same as the recorded clips are.
