I bought an 16e last week with the same chipset, just tested and it handles realtime recording of 4k at 60fps with HEVC (camera is "48mp" so the source is 8k camera source material).
Pretty sure most of the encoding/decoding of video is handled with special circuits these days.
Now, add enough layers and it'll probably falter, but with dedicated encoding/decoding circuits combined with a modern GPU it will definetly be a usable experience with some lower res quick pre-renders at worst but probably realtime for most content creator usages.
Content creation also used to mean writing novels by hand and stitching pixel art. You can do basically anything imaginable before 2010 in terms of creation (which is... basically anything worth mentioning?) before running into video as the bottleneck. Probably closer to 2020.
The first professional commercial 4K camera came out over 23 years ago, and the first smartphones and camcorders capable of 4K video were back in 2013.
The Macbook Neo has a 2.5x higher multi-core Geekbench score compared to the i7-4960X's, the top consumer CPU of 2013 (which could handle 4K video editing in h264), and its single-core performance is 5x higher. Plus, I'm 99% sure the MacBook Neo has a dedicated video decoding ASIC anyway.
The number of PowerPoint and slide presentations I sat through with sans serif white and yellow text on a dark purple background still gives me nightmares. For my presentation I went black over medium-light grey. The audience sighed with relief.

There's a patent (2017/0280211 A1) for using this as a data storage method, and there was a company called Lyteloop trying to leverage the idea for data storage with estimations for petabytes across constellation.
The article says 2.6 gigabits/second which is 2,600,000,000 bits/second, 2,600,000,000b/s * 0.5s / 8 is 162,500,000 bytes, 162,500,000 / 1,000,000 is 162.5 megabytes
