WIP Video - we'd love your feedback!
Added 2024-09-26 18:06:27 +0000 UTCOur next video will be out soon, all about the amazing story behind QR codes. While we continue to work on it, here's a preview! Some sections and animations are still in progress, but all feedback is welcome.
Thank you everyone!

He is very happy about it. Thank you!

2024-09-30 09:26:46 +0000 UTCHere are the comments from my 9-year-old son. 1. He likes that the QR code was done by hand because it helped understand how they work. He didn't like the choice to use William Tell Overture when making the QR code. A suggestion is to use a calmer music. But it is ok if it stays as is. He liked the progression from Morse code to barcodes to QR codes.

2024-09-29 20:49:52 +0000 UTCAwesome (basically a) documentary! I was never intersted in the store behind QR codes, but now after watching this preview I will definitley be looking more into the topic on Google Scholar. That aside, (if I'm not mistaken) my name should be at the end.

2024-09-27 21:59:09 +0000 UTC[2:26–2:33] The slideshow is fascinating and going way too fast :) [5:51-] Some shop chains around here use their own bar codes for their own products from a reserved range, which another chain can also use for their own products, so "every product you ever bought is uniquely identified" is not accurate.

2024-09-27 16:33:45 +0000 UTCThe reason I love veritasium is the mind stretching. Back in the early 2000s we tried to introduce QR codes to our marketing customers but they were considered ugly, confusing and space hogging. IMHO QR codes needed the pandemic to become ubiquitous. If you want to really blow your mind, deep dive on data glyphs. Kind of like hidden QR codes in plain sight.

2024-09-27 12:14:09 +0000 UTCThanks for sharing this. I found this to be an eye-opener for me. I knew a bit about bar codes, but the transition to QR codes was something I was unfamiliar with. A highlight was understanding that the game of GO was instrumental in the developement of QR codes.

2024-09-27 03:03:29 +0000 UTCIt might be worth checking out 3b1b's animation library Manim. Grant also has an excellent explanation of Hamming codes (a precursor to Reed-Solomon codes) on his channel, which may be worth a shout-out. In addition, I feel it's worth mentioning that CDs, etc. aren't "dead" because they can't be played properly in your disc player. The formats have a huge amount of error-correction built into them, but it's the ridiculous processing power required to make use of them that makes it infeasible for mass-produced CD players. If you pop it into your computer and rip it via iTunes or VLC or some other method (most GUIs leave the "use error correction" box unticked by default because it's so slow) you can totally pull a perfect track off a heavily-damaged CD that (e.g.) otherwise skips in the same spot.

2024-09-27 00:11:32 +0000 UTCThank you for putting this together, and the inclusion of Masahiro Hara. I was wondering if the painting of the Marquis de Lafayette was one by Morse, but the Internet sends me to a less glamorous painting.

2024-09-26 20:57:00 +0000 UTCTerrific! Tough to hang on through the discussion of the polynomial without graphics, but I’m sure that you’ll do your normal exemplary job.

2024-09-26 19:56:18 +0000 UTCGreat subject. Of course I would have liked to dee the animations of the math behind error correction... I believe som art has been done using QR codes and would have liked to see some of that too.

2024-09-26 19:50:13 +0000 UTCIt's ironic that when I click on "Watch in app" within the Patreon email that led me to this video, a QR code popped up over the top of your Patreon page! (Also, thanks for the "Welcome to the Video" message!)

2024-09-26 19:49:22 +0000 UTC1. As an IT professional, I'm glad you made mention of the security risks of scanning / using sketchy codes. If that hadn't made it in, I was planning to request it. 2. I found the deep deep dive on error correction algorithms and *their* origins to be a bit too much of a distracting 'side quest'. I'd almost think a briefer mention of them for this video, and a dedicated video for error correction, would help stay on topic focus. 3. About 10 years ago or so, while searching for a job, I handed out QR coded self-printed business cards. The QR was encoded with the URL to my LinkedIn profile. I got lots of confused looks. QR use wasn't widespread enough yet and people weren't conditioned to see it as useful / helpful. 4. If you're going to use a thumbnail that has the QR code with yellow smiley face, you might want to add to the video. It *is* actually possible to use color in QR codes already. It's used by some companies to embed their corporate logo for marketing purposes. Likewise, there are free generators online that average people can use to create colorized QRs. 5. FYI there's a website called UPCindex where you can type in the UPC code of an item and it will give you product information, etc.
