Demo of Raspberry Pi Video Wall with 9 Analogue TVs used in Vacation Forever's "Shadow" Music Video
Channel: Vacation Forever
Date: 2019-05-23

This is the first video in the behind-the-scenes series for the making of Vacation Forever's music video "Shadow." In this episode, the Creative Coder and New Media Artist Johanna Tano demonstrate her amazing art installation Analogue TV Wall. 

In the next episode, the video director Albin Eidhagen shows us how he created the visuals, and how he managed to live mix the videos on the different TV screens while filming it. Subscribe to get a notification when it's out!

» Johanna Tano explaining how the TV wall works:

"This digital driven analogue TV wall is connected in real time to a network streamed video. This is done by using one Raspberry Pi for each TV, telling the RPi to send composite video signal through its headphone jack, instead of the standard HDMI port. That means you can plug an A/V cable straight from the RPi into the TVs analog video input (or via a SCART adapter). 

To achieve the effect of the video stream being perfectly spread across the individual TV screens, there's a quite complex mapping system going on from a server. The system makes each RPi only send a specific area from the shared video (based on the position and relative size of each TV screen). Luckily this only needs to be done once, and I built a web interface to simplify and manage this video mapping process. 

The idea when making the installation was to have the TV wall function almost like any external screen. Meaning it should be ready to receive video from a VJ Software, camera stream, or interactive experiments. The only requirement is to use software with Syphon video output support."

Zacharias Zachrisson about the idea of the music video:

"The idea of this video started with an Instagram post in my feed by my friend Johanna Tano. She was working on an amazing visual art project with a bunch of old analog TVs. So I sent her a DM: “Can I borrow your TVs for my new music video?”. And she said YES!

How it works? I have no idea! Johanna is a genius. There’s a lot of matrix code, computers, cables and a black painted stand for the TVs. Together with the video director Albin we created custom made videos and animations for the TV screens which was live mixed when we filmed it.

If you look closely, you can see me skate on one of the screens. We filmed me skating around in a red spandex bodysuit. That was kind of strange.

I hope you like the video as much as I do."
