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.
