Earlier quoted context omitted.

YouTube just changed the ad milestone to 8 minutes, and this was posted after this change.

On the same topic, who determines the '10 minute' and '8 minute' time scale perfect for engagement and how did they end up with these numbers?

don't know how they arrived at that specific number, but it was done because in the old days of youtube a lot of channels would spam 1-2 minute videos for that ad revenue

that's why videos like these exist https://youtu.be/nfxpwbWBNuU

This is a really cool video and I don't mean to detract from it, but seeing how its 10 minutes and 8 seconds long annoyed me so much (and not for the reason you think). "10 minutes" is an ad milestone for videos on youtube. I systematically click away and hide videos that are between 10:00 and 10:20 minutes long: They'll almost certainly have been artificially slowed down to match the ad requirements. It's infuriatin…

I am guessing many uploaders just don't realize that yet.

Interesting facts that I didn't know before seeing this video:

- The opportunity rover captured a barren scene which was named Rub Al Khali (Yes! On Mars!), named after the Rub Al Khali desert area which touches UAE, Saudi, Oman and Yemen. (1) (2)

- The video says that Mars rovers send back images (not videos) and then those images are stitched together to create videos, because "nothing ever moves on Mars". But I wonder how a Mars video will look. Maybe it will surprise us (movements due to winds).

- Mars has a lot of clay (i.e. it was once a watery planet)

- Some videos took 1,000 images to make

- There is a beautiful selfie at timestamp 6:41

- There is dune named "Namib" on Mars, shown at timestamp 9:10, named after Namib desert in Africa. (3) (4)

10 minutes is the the milestone for "mid-roll" ads. As far as I can tell, this video has no ads in the middle.

I saw about 4 full-replacement of video ads. It might be because I selected 4K video. I wonder if they push more ads when you select a higher quality.

The music overlay really gives the video a nostalgic feel...even though I've never been to Mars.

For those who had the same question I had about whether these are actual colors, the narrator talks about the change in color between images and the color correction done in post-processing around 5:45.
