How to watch videos slow motion in YouTube

The YouTube video player lets you easily change* the playback speed of videos. You can watch a YouTube video in slow motion and see the frames in more detail or, if the video is boring, you can switch to fast motion mode and skim through the video by doubling the playback speed.

YouTube is home to countless eye-popping videos, everything from epic outfield catches to freaky car crashes to seemingly impossible dance moves.
Indeed, for the past couple days I’ve been watching, and rewatching, this video and trying to figure out how a person’s legs and feet can move that way. (It gets especially amazing around the 1-minute mark.)

Bottom line: there are times when it would be great to see a video in slow motion. YouTube offers this option, but it’s not exactly out in plain sight.

To adjust playback speed if you’re using the Chrome browser, click the Settings icon in the lower-right corner of the playback window, then click the Speed selector. Choose 0.25 for quarter-speed playback or 0.5 for half-speed. (Obviously you can also opt for faster playback if you wish.)

Don’t see that option? While I found it in Google Chrome, it wasn’t visible in either Firefox or Internet Explorer. However, you should still be able to access it in those browsers by enabling the HTML5 version of YouTube’s video player (click “Request the HTML5 player”), or by using the site discussed below.

Play YouTube Videos in Slow Motion

Method 1#: YouTube HTML5 Video Player

As I said earlier YouTube HTML5 player is not available by default for the viewers, but you can get it easily by following the below link. Once you visit the link click Request the HTML5 player and instantly your default video player will be changed to HTMNL5 player. Now search and open any video, click on Gear icon (bottom right) and choose speed. Below is the same in steps by step procedure.

Step 1: Go to http://www.youtube.com/html5

Step 2: Click on Request the HTML5 player button and wait for few seconds until you see the button has been changed to “Use the default player”

Step 3: Now search for any video and open it

Step 4: Now click on Gear icon (bottom right)

Step 5: Next click on Speed, then select your video playing speed from 0.5 to 0.25 and you are done!

I would recommend you to use 0.5 speed, because when I chose 0.25 the video was playing in slow motion but I was not able hear the sound. You can also play video in fast motion by following the same steps, but instead of selecting 0.5 or 0.25 select 1.5 or 2 to increase the speed.

Useful Background Dimmer Addons For Firefox

Here’s a list of useful background dimmer addons for Firefox which you can use to dim backgrounds on website when viewing videos so that they are more enjoyable to watch. Having a bright background around a video isn’t very appealing, because it puts extra strain on the eyes. To enjoy a video more, you’ll have to dim everything down so that nothing distracts you from watching the video.

That’s exactly what the addons that we’re gonna talk about are for.

Turn Off The Lights

Background Dimmer Addons For Firefox (1)

Turn Off The Lights adds a button for dimming everything in the addon toolbar. Clicking on that button while watching a video in a tab down below will dim down everything around the video, see image down below.

It’s a classic background dimmer addon, and it works great no matter which website you’re on. This means that you can use it on other websites, not just YouTube. Wherever there’s a video frame it’s gonna be detected and everything around it is gonna be dimmed after you click on the button.

Get Turn Off The Lights.

Screen Dimmer

Background Dimmer Addons For Firefox (2)

If on the other hand you don’t like the fact that the entire screen is bright when watching videos, then you might be interested in a screen dimmer that dims the entire screen.

That’s exactly what this extension which bears the same name, Screen Dimmer, does. It will dim down everything within all the active tabs, no matter what you might have open inside of them. Use Ctrl + Alt + + and Ctrl + Alt + – to adjust the level that the tabs are dimmed, or use Ctrl + Alt + 0 to reset the levels to normal.

Vimeo Dimmer

Background Dimmer Addons For Firefox (3)

Vimeo Dimmer is for all of those who might be interested in dimming background on Vimeo videos specifically, if it’s not working with Turn Off The Lights for example.

Everything works pretty much the same like with Turn Off The Lights. You get a toolbar button which is gonna turn off background on all the videos, no matter if they’re on a single video page, channel or group page.

Tube Enhancer Plus

Background Dimmer Addons For Firefox (4)

Tube Enhancer Plus on the other hand is a full-fledged YouTube improvement suit that has a wide range of options for tweaking YouTube, one of which is the background dimmer.

After installing the extension, you’ll be given a toolbar down below with options for managing YouTube. There’s a light bulb icon which after you click on it will dim down the video background and at the same time also increase the video player to fill out the entire page, so that the video is more enjoyable to watch.
