Re: [sync-on-the-web] announce for the tag at ME-IG


Rob,

Thanks for your comment!

Your idea, using WebVMT to control DMX lighting behavior, is interesting 😊
With your idea, single web page can produce a live entertainment experience with lighting which is synchronized with mp4 data, which must be fantastic.

In my understanding, WebVMT is an abstraction layer to control lighting devices. Since data format of DMX is binary basis and vendor specific, there is less interoperable between different devices. However, with WebVMT, we can represent behavior of lighting device with human-readable basis, e.g. { color: “rgb(255, 243, 127)” }. Furthermore, your idea will be applied to other lighting devices, e.g. Hue ( https://www.philips-hue.com/en-us ).

I’ll prepare for sample DMX data with video. I’ll let you know when it’s ready.

Ken,

Thanks for your excellent presentation in the MEIG meeting last week.

You mentioned a live screening use case that requires DMX lighting data to be streamed in sync with video. I believe that this may be possible using WebVMT’s data sync feature [1] and I’m interested in creating a prototype to explore this further. The basic idea is to export DMX data to a VMT file that is synchronised with a video element in a web page. Please let me know whether you can share sample video with DMX data that would be suitable for a demonstration of this kind.

I recently produced a video [2] that demonstrates how WebVMT can synchronise web map rotation with the camera heading to simplify image cognition for an aerial observation use case. This is a similar concept and may help to visualise the demo that I have in mind.

I look forward to hearing from you.
