Newb here. If you watch this short film linked below there is a section near the start 4:35 showing ruined skyscrapers that have been added into the background. I have tried messaging the channel on how they did this but have gotten no response. Please can you tell me the quickest and cheapest way to recreated this in terms of programs ect??? Thanks a lot!!!
