This project looks pretty cleaned up to me already, or do you mean you cleaned it up after merging both of them?
Maybe you can share (in text form) what problems you had with merging these two project or maybe even which tasks of merging them were easy to perform.
That would help the creators to improve their system and it would help other users, who also want to merge these projects, to not struggle at the same points.
You might also want to make sure to not show too much of a marketplace project in a video, so people can’t just recreate it by seeing it.
Maybe just blur out the default function names etc. (:
