Not the post author but I tried this with ffmpeg and failed. Do you (does anyone) want to share some pointers?

I used something like this a few years ago in a project sort of similar to this one. There's a bunch of parsing and processing to do with that, and the "0.3" value is ... fiddly, but it worked pretty well: ffprobe -show_frames -of compact=p=0 -f lavfi "movie=THE_VIDEO_FILE,select=gt(scene\,0.3)" -pretty`

I played with that too before.

`ffmpeg -i input.mp4 -vf "select='gt(scene,0.4)'" -vsync vfr frame-%2d.jpg`

(from the repo pforret/filmpace)

For this project, I want to find an A.I. solution for finding the most 'interesting' frames. Not even sure how to measure interestingness yet, might be the presence of text, the presence of a human ...

Based on the example shown on the page, the output doesn't seem very good. If that's one of the better examples the software produced, I don't think this will be useful in practice.

This is one of the first results. The third, if I remember correctly.

I got this running yesterday (Sunday), and I wanted to write the blog post first to test if there was any interest in this topic. Apparently, yes. Now I only have to do the remaining 80% ;-)

I saw a YouTube video by a guy who specializes in building D&D characters. He spends twenty minutes going into detail on each one, and then makes the pitch for subscribing to his Patreon account with something like "members get all the details in a convenient list so that you don't have to keep going back to this video." So he's using the same bit of friction that this article is trying to solve, to fill his rice bow…

Do you remember what was the channel? Thanks

Definitely would use this. Instructional video instead of step-by-step text is a personal pet peeve. I know it's a lot easier to just record a video to show something like "how to replace the battery on a cordless vacuum" or "removing a sink basin nut" but it's often such a painful experience for consumption (watch a moment, pause, scrub back and watch again, pause, continue, pause, all with potentially gloved hands…

People have a mental cap on what text should cost. If someone creates instructional content that provides thousands of dollars in value, they can sell videos for $200+, but a book version is hard to sell over $50, even if both provide the same value. Even for free content it is easier to monetize YouTube than it is to monetize a blog.

If we want people to create more text-based material, it needs to have similar financial incentives.

I have no data to back this up but just taking a stab in the dark - a possible reason might be because people generally tend to prefer learning from someone talking about the subject matter?

I know most all of us here are techies and very used to cracking open books and documentation and text tutorials to teach ourselves stuff, but many people are not like that and especially if you're new to a subject, sometimes books just don't help things to click as well for some reason.

There's probably something to do with the way material is structured and presented differently between talking about it and writing about it, but I wouldn't know what to say about it.

I dunno, just a guess because it's an interesting observation to think about.

Do video formats support structured meta data to be embedded in them?

If I make a video of me cooking, can I embed the recipe in the video, etc. Not just visually, but i.e. at 10s, I digitally insert the data "Add 1 cup red peppers". It isn't necessary a caption of something said or shown, just extra data.

Could a video creator leave substantially more metadata in their videos? I always assumed the pop-up metadata was externally stored and timestamp synced. Is there a way to embed it?

I'm on the other end of this in a way. I think it may come from having to read and write all day every day. Sometimes just having somebody yak at me for a few minutes is useful.

I really enjoy watching instructional videos, especially for recipes. The demo of the cooking techniques is almost always hard to write or talk about, and easy to show.

In the kitchen it works this way for me:

1. Watch the video once or twice all the way through to "learn it" and decide if it's what I want to do.

2. Put together my mise en place and basic prep for the recipe. Learning to do this was a game changer.

3. Finally, put it on my phone or tablet in my kitchen and let it play while I work, it's mostly audio at this point as I've "seen" the content a few times but I'm just listening as if the video is a coach. I'll hit pause at the major steps, and scrub back if I need a refresher on a technique or step.

I've gotten through some very complex dishes this way, and never hit the equivalent rhythm using cookbooks or recipe websites. The audio part of step 3 is really critical to me as it helps me focus on the food rather than remembering all the steps and it's just fills up the background space in my kitchen or act as a coach. The only way it would be better for me is if it automatically paused after each step and I could then ask it "what next?" or "go back two steps, I missed a step" or some other audio prompt.

Have you considered paying for the patreon regardless because you consume his content one way or another and value it?

I think ideally the creator would be compensated by PrintThatVideo, who is taking their content and repurposing it.

I consume hundreds or thousands of creators' content that I value more than this particular channel. If I felt the duty to donate to each one, let alone subscribe , I would consume much less of it and live in a smaller world. Perhaps it is a rationalization, but I don't feel that consuming content that someone offers to me for free creates an obligation on my part, whether I love it or not.

And don't they make money from ads or subscriptions via YouTube or whatever platform they're on? I don't want to bother paying each creator, but I'm fine subscribing to YouTube or Pandora.

I was thinking the same thing. Extraction and basic formatting of information from human language is something that LLMs excel at. Especially if the result is being shown to a human so small mistakes can be tolerated.

It could also dramatically increase quality, look at the below from the example PDF from the page: > Garlic balsamic chicken, you'll be making over and over. By sear your chicken. I resin wine. Grab yourself a nice large bowl, extra virgin and olive oil. Balsamic glaze. Tomato paste. Honey, fresh lemon juice, garlic, Oregano fresh thyme, coat my chicken with this beautiful balsamic, no balsamic, left behind. Don't yo…

Looks pretty good to me when I use all "the tricks": https://chat.openai.com/share/18bb729c-82e9-4c7d-abc1-a977c9...
