The thinkpad-x13s-snapdragon is fanless and uses a qualcomm snapdragon processor, so an ARM like the macs use but lower performance. Batttery life is reputedly in the 20+ hour range.

Caveats:

• kinda pricey, 1K
• this arm chip is slow compared to macs.
• out of the mainstream so better do your homework on whether linux is well supported.

Laptops based on the snapdragon elite processors will come out this year, and performance should be comparable to the Mx macs. So maybe better to wait. Although, those may be considerably more expensive, and who knows what linux support will be like, especially at first.

I don’t like apple as a company and their attitude towards repair makes it so i feel obligated to never recommend one of their products, but if you need it to be fanless, a macbook air is prolly your only really good option, honestly though an m1 should be just fine (I’m assuming your video editing workloads are pretty light), also i recommend checking out Just Josh on YouTube https://www.youtube.com/channel/UCtHm9ai5zSb-yfRnnUBopAg, he has some great laptop reviews
