Netflix has some big plans to save bandwidth and the company is going to re-encode its whole catalog part of its plans.
The plans will save people about 20 percent of bandwidth on the current Netflix TV shows, the company says there will be no loss of quality on movies and TV shows.
It’s a much more complex movie, at least from a purely visual perspective. This means that Netflix’s encoding servers have to work a lot harder to get it down to the same file sizes as they do with “My Little Pony,” leading to more compression and possibly more visible artifacts at low bitrates. That’s why in 2011, Netflix’s video algorithm engineers realized that they shouldn’t apply the same encoding rules to these two very different titles. “A one-size-fits-all model doesn’t give you the most optimal quality,” said Aaron.
As Netflix is responsible for a massive amount of Internet traffic at peak times, then a 20 percent saving is pretty significant to overall traffic.
