Slow-Motion Picture: Netflix Is Rolling Out New Playback Speed Controls

You can stay in the Daredevil universe just a bit longer with the slower playback options.
You can stay in the Daredevil universe just a bit longer with the slower playback options.

Netflix is now letting some users adjust the playback speed of its content, meaning you can finish The Irishman in a mere fraction of its 3.5-hour run time (or make it last even longer).

As The Verge reports, viewers will have the option to watch videos at 0.5, 0.75, 1.25, or 1.5 times their normal speed, and the feature will be available for regular streaming content and offline downloads. So far, Netflix is only offering it to Android mobile users, but tests are in the works for iOS devices and the web app, too.

When Netflix shared plans to develop playback speed controls back in October 2019, some leaders in the entertainment industry voiced their opposition. Filmmaker Judd Apatow, for example, took to Twitter to explain that distributors like Netflix shouldn’t be allowed to alter content created by others. The streaming giant didn’t abandon the idea, but it did take the negative feedback into consideration. In a July 31 press release, Netflix explained that it was limiting the number of speeds to just four, and each program will always start playing at the normal speed—that way, viewers will have to consciously choose to speed up or slow down videos on a case-by-case basis.

And while content creators may dislike the thought of having less control over how people experience their work, it’s not a new concept. As Netflix pointed out, DVD players and DVRs have long included playback speed options—the feature has also been available on YouTube for years. More importantly, speed controls give users with vision impairments the opportunity to accelerate the audio—since some can process audio faster than sighted folks—and it gives deaf and hard-of-hearing users the chance to slow down the subtitles. Both the National Association of the Deaf and the National Federation of the Blind have endorsed Netflix’s new feature.

While you’re waiting for Netflix to expand the offering to iOS and web users, here are 25 other hacks to enhance your Netflix viewing experience.
