Curious about the journey from photons to the image or video on your phone? I made a video with Grok @bot, @imagine, and Voice explaining the physics and theory behind it—100% on my phone just chatting.
Part I: photons to digital signal
Part II: digital signal to pretty picture
Pro tip for Grok @bot: Ask it to QA every single frame before handing it back. It saves QA time so you can focus on high-level direction.
All technical visualization, including relinearization of the video footage from Grok @imagine to be physically accurate, is done by Grok @bot.
Update: added more technical details with higher quality encoding for completion.

A physics video on photons to pixels, made entirely on a phone
Yun-Ta Tsai, Sr. Staff Engineer at Tesla, produced both parts by chatting with Grok's bot, Imagine and Voice: photons to digital signal, then signal to picture. Grok did the technical visuals, re-linearising its own footage to be physically accurate, and QA'd every frame on request.
