Lightbow Sorry to comment on packaging rather than content, but I was surprised to see one of the longest, raciest YouTube advertisements I've ever seen before what's supposed to be a kid-friendly educational video. I'm not offended or anything, but if I were to have the same experience in front of a classroom of kids, I'd be totally fired. I thought the point of Patreon subscriptions was to cut the need for stuff like this. How much money would you need to raise per video (either on Patreon, or via corporate sponsorship) to cut out ads entirely?

June 2, 2015 15:04:26 · Reply

Henry Reich This is a good question, thanks for asking and I'm sorry you had to sit through an inappropriate ad. At this point I've been turning off overlay ads on new videos as well as turning off unskippable pre-roll ads (like the one you watched) for the first 24 hours or so of new videos, so if you watch right away you don't have to see ads (or at least you can skip them). I don't have a set number goal for turning off all ads for the first week a video is live, and one potential issue is that a lot of patrons put a cap on their monthly contributions, so the full amount listed on the patron page (minus transaction costs and patreon.com's cut) is only for one video/month, any additional videos receive a significantly lower level of pledges.

A New Way To Watch (Vessel Announcement)

Hey There Patrons, It’s been a really exciting month for here at MinutePhysics! It’s now three years since I’ve been making videos full time, plus MinutePhysics recently passed the 200 million view mark. But that’s not all…(drumroll)... I also recently signed up to make my videos available on an exciting new video site called Vessel.com to give you even more options for watching MinutePhysics. Check out my vlog announcement here for more details: https://www.youtube.com/watch?v=eitTd8LODDE Or just read these bullet points: • Vessel is a clean, streamlined video platform with curated content and minimally-intrusive advertising (no popup ads!). • It’s free to watch videos on Vessel, but there’s also a subscription option where you can pay just $3 a month and get early access to content across the site, including all future MinutePhysics videos. • If you go to vessel.com/sciences to subscribe, Vessel will pledge additional support to MinutePhysics, MinuteEarth, AND the excellent Veritasium. So your subscription will help fund lots of new science videos! • Additionally, if you sign up with Vessel before 11:59pm Pacific Time on Thursday March 26th, you’ll get a FREE one-year subscription - that means you’ll have pre-release access to videos all year long without paying a dime (and like, really for free…you don’t even have to enter your credit card information). If you’re not interested in checking out Vessel, don’t worry! I’m still going to post my videos on YouTube and iTunes, too, as I always have. Thanks again for supporting me! I hope to see you soon, wherever you want to watch my work – on YouTube, iTunes, or now Vessel. Henry

Ho Yin Cheng Ok, so I had already signed up for Vessel yesterday (same year offer, but from LinusTechTips) and tried it out. Before I list my thoughts on the platform, I have a question: Does early access on Vessel mean that videos come out slower on YouTube? If so, then why would I bother continuing to support you via Patreon (formerly, Subbable - yes I've been supporting since day 1)? The only reason I'd have left for supporting you is for the sciences, and while I'd love to do that, I'd probably much rather put those types of donations towards the education charities that I try to support. Now for my thoughts on Vessel as a streaming platform (copy pasted from my comment to Linus): 1. Signup forces you to subscribe to categories and follow people to continue? I literally don't subscribed to anything outside of two types of videos so I had to just pick one randomly to continue. (ended up just removing everything after signup) 2. I don't have too many Firefox plugins installed, but usually all websites work. But Vessel is completely broken and tells me to upgrade my browser. Uhhh... sure. I'm actually on the latest version of Firefox, so what gives? 3. The website homepage is laggy as hell because they animate parts of the videos in some of the previews. Why do this? The previews are also so large that I can 100% see this being a pain in the ass to use to see what new content came out once you're subbed to more than a few people. 4. The video player is not responsive. It's hard to get the controls to appear without pausing and resuming (in fact, it seems impossible - try doing it in fullscreen). 5. Control menu has so many design quirks (looks and feels like default Bootstrap so badly that I wonder how many real UI designers they have on their team) that it simply feels clunky to use. They made so many UX mistakes that the website actually feels amateurish. Overall, I'm glad to see all YouTube creators trying to break their dependence on YouTube. However, I think your usage of Vessel is not representative of common users. Especially those of us who are such heavy users of streaming services that we actually pay for them (as I do via Patreon). For us, Vessel is a pretty poor platform. Thank you for reading this, and I hope you can pass along these comments, and similar ones, to the other YouTube creators who are also pushing to Vessel.

Michel Payette Hello Henry, The sun is about the same size as the moon when we look at it from here, if the sun was hollow and a photon would emit from one side, and travel in strait line through the center...(and if we could see it) then it would require something like 4 seconds to reach the other side ! This make it easy to follow with the naked eye...seems almost slow !
