It was just an example of different ad structures for different length videos, not anything close to a final proposal. I mostly watch very long form content (>30mins), so my example is probably not the best for shorter vids.

This seems like a crazy amount of ads to me. On live TV, I wouldn’t expect more than one ad break every 15 minutes of broadcast, with fewer on things like feature films

It’s sadly not when compared to live TV. The thing to remember about live TV ad breaks is that commercials are longer, and so are the breaks. On TV, each commercial is closer to 30 seconds, and the breaks are closer to 3 minutes. ~12 mins/hour (4x 3 mins breaks per hour) for TV vs ~3 mins/hour (6x 30s breaks) for my example. Even if youtube doubled up and put 2x 30s ad breaks in a 10 mins vid, that’s still 6min/hour of ads.

Front-loading the ads makes sense for shorter vids. I chose the middle because youtube seems to want to put them during the video, even on the shorter vids. I chose 30 seconds based on ads being 2x 15 seconds long each, which is what I normally see while watching Youtube without adblockers. Maybe prioritize shorter ads in shorter vids? So, 2x 5 second ads instead of the 2x 15 second ads.

My major grip with the current ads are that they are obtrusive and repetitive.

On broadcast TV, I dont mind ads as much because the shows were written, filmed, and edited with predictable ad breaks in mind. I have a good idea how long the ad break will be and when they happen. Makes it easy to plan bathroom breaks, drink refills, or discuss what we’re watching.

On Youtube, the ads seemingly pop up at random, usually in the middle of a sentence. Sometimes, there will be 2 ad breaks, and other times, there are 4 ad breaks for similar videos. If youtube would make ads consistent (30 second ad break at the half way point for < 10 mins vids; 15 second at break at 1/3 of the way through the video and a second one at 2/3 of the video for 10 - 30 min vids; etc) and content creators would edit their vidoes for these predetermined ad breaks, they would be much more palatable.

I get that the ad pool is based on tracking data/video content, but watching the same pool of 3 or 4 ads makes me less likely to buy something. Throw in some random ads in there, too, to break up the monotony.

Can’t watch the video at work, but I suspect the video is about coagualtion & flocculation. The resin is coagulated from disolved resin particles into suspended resin-alum complex particles too heavy to remain suspended in solution, which is why a small-scale settling pond works.

It’d might be a bit quicker/easier to put it through a filter or series of paper filters. Nothing crazy. Even a coffee filter should get most of it. Micron scale filters aren’t terribly expensive but clog quickly, so it’s best to run a coarser filter to get most of the big chucks first. Granted, not sure how long the coagulation process takes versus the flocculation process. If the coagualtion process is slow but the flocculation process is fast, filters probably won’t save much time. Though they may make cleanup easier.

Eventually, the IPA will be diluted with water from the aqueous alum solution (I assume he’s using an aqueous solution as alum is barely to not alchohol soluable). There’s the salt trick to separate the azeotrope, but I haven’t personally tried it.

Lots of work, but still better than those guys who distill the dirty IPA with non-explosion proof apparatuses. shudders in OSHA
