I've been creating AI videos for a while now...

But this was my first time using the Canvas feature on Renoise.

And honestly? Game changer.

Building the entire workflow in one place character reference sheets, storyboards, video nodes, all connected felt like actually directing, not just prompting.

The result? A 40-second cinematic short with a twist nobody sees coming. Watch till the end.

I’d love to know your thoughts what would you rate this creation/10 ? Tell me in the comments 👇✨

I never wanted to be a starving artist.

Wanted to be a talk show host. Then a Vegas lounge singer. Anything but an artist.

For the Renoise × Contra challenge I got personal.

60 seconds, autobiographical, every frame on a plan: childhood daydreams shot in degraded consumer formats (Kodachrome, broadcast NTSC, grainy 16mm), graduating into large-format cinema as the kid works out what he's been doing all along.

FacePass held the shots I needed, and the interface stayed out of my way. Cool tool, genuinely easy to use.

Feels straight out of a trailer .. of a 80s show redefined with a modern spark.. Great work! Would love to know your opinion on my submission as well. Good luck!
