Long answer: Just jump around. Once you get to the last 1/3rd of the video, there's a lot of close ups of the part of the laserdisc that recorded the credit sequence. The on-screen (laserdisc) text is clearly visible.
The author moves a flashlight around to show how the angle is important; something that won't come across as well in a blog entry.
In this video, Tech Tangents reviews the Andonstar AD246S-P digital microscope and uses it to achieve a "world's first" by capturing clear images of video data and text directly from the surface of LaserDiscs and CEDs (Capacitance Electronic Discs).
Microscope Overview and Setup
Purpose: The creator purchased the microscope specifically to document the microscopic structures of obsolete media like CEDs for the public domain [00:14].
Features: It features a 1080p sensor, HDMI output, and a flip-down display [02:41]. He notes the importance of the included remote control to prevent camera shake at high magnification [04:10].
Build Quality: He highlights thoughtful design choices, such as captive plastic inserts in the screws to prevent them from biting directly into the metal support tubes [05:51].
Initial Testing and Performance
Coins and Wafers: The microscope provides impressive clarity when viewing historical coins and silicon wafers, where individual dies and traces are easily visible [11:30].
Magnification Concerns: He expresses skepticism regarding the "ridiculous magnification claims" often found on these products, finding that the high-magnification lens can sometimes be hazy [13:07].
Visualizing Video Data on Physical Media
The core of the video focuses on using light refraction (diffraction grading) to see the physical encoding of video signals.
LaserDisc (CAV): Using a "The Mind's Eye" LaserDisc, he successfully identifies horizontal blanking pulses and color bursts in the disc's pits and lands [16:27].
Reading Text on a LaserDisc: In a major breakthrough, he discovers that by positioning a flashlight at a specific angle, he can actually read the end-credit text (e.g., the word "Keyboard") directly off the disc surface [22:54].
CED (Capacitance Electronic Disc): He examines a damaged CED of the movie True Grit. He manages to capture a remarkably clear image of the film's credits etched into the disc's microscopic grooves [25:57].
Additional Observations
Optical Media Tracks: The microscope is used to visualize the distinct data sessions and track separators on a CD and a CDRW [27:00].
Smartphone Sub-pixels: A close-up of a Samsung S24 Ultra display reveals the sub-pixel arrangement of its OLED screen [28:37].
Conclusion: The creator concludes that the Andonstar AD246S-P is highly effective for technical documentation and hobbyist use, especially given its ability to resolve the fine details of analog video media [28:57].
It's likely based on just the transcript, even if it describes visual things, it likely guesses those things from the transcript text only.
Maybe it's better now, but that was how it did it recently. To be convinced that it "watches" the video, I would need to see evidence of it referring to facts that are strictly only possible to know from the video, but not guessable from the audio.
yes, you must save it to a laserdisc, and then observe it though a highly magnified digital microscope looking for a specific frame.

this should be the main link
No!
It took me like 2 minutes to find the relevant part:

Gemini can watch youtube videos.

You can try it with your own recorded video. I record myself doing exercises and Gemini gives me really good feedback on my form.
You can ask your human to watch the video and write the text blob for you.
use gemini and ask it to summarize a youtube link
