“Remuxing preserves the original video and audio quality because it doesn’t involve any compression”

So, what you said - it’s a 1:1 copy of the source. With no compression. Which is what I said, as far as I can tell?
What I don’t understand is why the article says it allows for smaller file sizes, when I’ve found without fail that remuxes are the largest variety by far. It made sense to me that a file produced without compression would be larger than the same file, compressed.
Throwing my +1 behind Hetzner, it’s so much more bang for your buck than with a VPS and I’ve been pleased with the stability and uptime I get out of my auction box.
