You could use the entire block in. Single transaction and you would have a video of less than 4mb at a cost of over 3k usd. To do the same thing in 10000 transactions across several blocks the cost would be 2x to 2.5x more expensive and. cause 30% more chain bloat. In the end it’s a short low quality video that’s impractical beyond novelty. Having it broken into small pieces doesn’t change anything beyond the cost and bloat.

I guess you have to ask yourself if 30% more chain bloat is a reasonable trade off for your virtue signal?
