In the context of the Lyon Intergalactic Science Fiction Festival, AOA Prod & Les Marathons du court-métrage organise "Les 48h plus tard" which is a competition where a film must be made in 48 hours, lasting 5 minutes maximum with constraints given by the organiser (theme, object, music, ...). Within this framework, we were able to make a short film on artificial intelligence with the association 3K Image. I was then able to entirely take care of the sound and music part of this short film (sound recording / editing / Sound Design / mixing etc...).
