Not an expert on this, but video editing is generally considered a fairly demanding process on computers. I'm pretty underwhelmed by all these options.
Processor: First option has slowest clock speed (2 GHz), but most cores (8). Second option has middle clock speed (2.1 GHz) and 4 cores. Third option has fastest clock speed (2.6 GHz) and 2 cores. I compared these processors on a benchmark website and the middle option was clearly inferior. The last option is faster single thread, but the extra cores on the first option give it a bit of an edge. However, it says the that first option ships with a 32-bit operating system. The processor is supposed to be 64-bit, but if it's operating as a 32-bit system then you definitely want the last option. 32-bit is like early 2000s technology.
Ram: 4 GB on all, this is on the low end these days, but I guess it could be sufficient?
Memory: All three of these models are somewhat deficient in this category. They have eMMC memory rather than SSD, and they only have 64 GB, 32 GB, and 64GB respectively. SSD would be preferred over eMMC, but that's not an option here. 64 GB is not a lot of space for videos.
Honestly, I wouldn't buy any of these computers, but if push came to shove I would likely get the last option. These are definitely super budget specs. I tried comparing these computers on a benchmark website, and I couldn't even find most of these components. I did find the GPU on the last option and its supposedly in the bottom 1% of GPUs. Combined with the CPU it was in the bottom 2% in terms of it's quality as a computer workstation (e.g. mixing music, video editing). Honestly, my older iPhone SE might outperform these PCs.
I know it's nice to get a budget PC, but these are so budget that if you spent twice as much money you might actually get a 10x better computer. I've never owned a chromebook and I don't do any video editing so you might know more about how it fits your needs.
Edit: the last option is supposedly only 720p resolution. I wouldn't get it. In that case, the first option might be better.
