Laser tracing on video wall

[Yash Velguenkar]

I have seen videos where lasers draw on video walls following exact content on the video wall. i was wondering how we do that? is there a third party app that integrates with beyond ? how do we carry out those complex mapping sequences? i want to know how to make the laser do it.

Its purely cleaver placement. There is no real mapping going on. It's mainly done with the advanced draw editor.

Are you tellling me its all done by drawing it all out in beyond and then manually alligning it on the screen?

 

[Bob@Pangolin]

Yes, often this is done this way.

Laser line draws are, as Bob said, essentially done manually within Beyond. This is the only method I know of for precise laser line draws. If you are looking for automated ways of laser-to-video/audio interaction, there are programs like Touch Designer and Mad Laser that have some features. I'm hoping that Pangolin eventually develops internal features for laser-to-video mapping (fingers crossed).

I was always under the impression this was done with the "real time video tracer" feature included with Beyond Ultimate.

I have experimented with Mad Mapper which traces video and works with beyond. This can be effective but i feel needs to be running on Saturn Scanners or be able to work with distrubuted scanning setup (i have yet to do this experiment)

It strongly depends on the requirement regarding output quality (line accuracy, output points…) and the content you want to overlay.
Best quality is clearly done if you draw the points and manipulate movements in Beyond directly. Tracing is really limited depending on the complexity. But in case you have access to experts in after effects and/or C4D, they might support your work significantly by implementing position markers in simplified version of the final video content. With this, you can redraw the points and cues much easier in Beyond then.
