free video software recomendations

[mc141]

so i have a lot of ideas but no way to get them out. i don't know crap about editing at the moment but want to learn

 

so i was wondering what free video editing software (windows or Linux) would work for video editing.

 

adobe is too expensive for me at the moment for the full versions and i don't like the subscriptions model either as the winter months its hard to pay for more than rent food gas ect.

 

things im looking to do/learn if possible on free software

green/blue screens

changing the audio/ading background music

inserting objects into the video. example putting an object over some ones face

 

some edits/vfx  i want to try to do at at some point and yes i know it wont come easy to do and will look like crap most likely 

 

yes i know trhis video is stupid but its another thing i wanna do
