Videos under 10 minutes can’t be monetised, I’m guessing they’re keeping that bit.

Videos under 8 minutes can't have mid-roll adverts, but a 2-3 minute video can be monetized and serve front and end roll adverts. Even a 30 second idiot video (IE Shorts) can be monetized but if it's in the slack-jaw brainslop category (IE Shorts) you need a crap ton of views on it to make money.

About 2 months ago I did an experiment on my youtube page where I made a stupid 40 second video and then formatted it for regular format and idiot format. Regular format got 1400 views and made $5.86. The shorts video got 2293 views and made .54 cents.

Most of the shorts views were in the first 4 days and then the algorithm dumped the video. That's one is done. It won't been seen again. The long form format got most of it's views in the first 10 days but it continues to get views every week.
