When you stream movies on your network media player/media streamer, Smart TV, or Networked Blu-ray Disc player, from online sites like Netflix, Hulu or Vudu, you don't want to have to wait while the movie loads, or buffers. You certainly don't want the movie to stop every few minutes to load again. In order to have smooth standard definition video, you need a connection that is more than 2 Mb/s. For HD or 3D, you need higher speeds.
You Need Fast Internet Speeds for Streaming Video
When streaming from your Netflix Instant Que, the Netflix service will adjust the quality of video to its assessment of your internet speed. If Netflix determines that you have a slower speed, it will not stream high definition quality video to you, even if the movie or TV show is available in HD.
Other video streaming services, such as Vudu, let you run a test to see if the higher quality video will play on your media streamer. If a video halts and buffers repeatedly while you are watching it, a message will appear asking if you would rather stream a lower quality version.
What Internet Speeds Are Available?
While there are many rural communities that cannot even reach the 2 Mb/s speed, more of the larger cities, suburbs and urban areas have speeds available of 10 Mb/s and above. It is not limited to broadband/cable internet. On a recent visit to Southern California, I experienced internet speeds nearing 20 Mb/s from a DSL internet connection.
Some providers offer DSL speeds of 24 Mb/s and above, while some cable providers offer 30 mpbs or higher. Google Fiber (if you are lucky to live in a community that has access to it) offers 1 Gb/s (one gigabite per second) speeds. These ultra-high speed connections can handle just about any video we have available now and much more.
How Fast Must Your Internet Be?
Many internet providers charge a premium for faster speeds. To get an idea of your internet speed plan, look at your internet provider bill or check under internet services on your cable or phone bill.
You can also test your current internet speed using the speedtest websites. If you want to upload and view your photos or watch online videos, consider opting for a faster internet package.
What Internet Speed Should You Choose To Watch Movies?
With Netflix, while you can stream at internet speeds of 1 Mb/s, the quality will be grainy on your big screen TV — as if you were watching a VHS movie.
After scouring the Netflix website, I spoke with Steve Swasey, Vice President of Communications for Netflix.
As a guideline, Swasey suggested the following minimum internet speeds for Netflix:
1 Mb/s for viewing on a laptop computer
2 Mb/s for viewing standard definition video on a TV
4 Mb/s for viewing High Definition video
5 Mb/s or more for the best audio and video experience
In addition, since the discussion with Steve Swasey, it has also been revealed that:
The Netflix streaming service can determine the speed that a video is streaming and will adjust the video quality to match that speed. As a result, you don't experience interruptions and buffering of the video but the picture quality may also suffer.
Vudu Suggested Streaming Speed
When you rent a movie from Vudu, you are able to choose the quality of your video. Vudu's better quality audio and video "HDX" format costs more to rent than HD or standard definition videos.
To be sure the video will play smoothly, you can watch a two-minute preview test before making your final rental quality decision.
When you click on a movie, you can find a speed requirement chart under the "more info" menu tab. This chart will give you an idea how fast you need for each quality of video.
1.0 - 2.3 Mb/s for SD — Standard definition video
2.3 Mb/s - 4.5 Mbs for HD — High definition 720p resolution video
4.5 Mb/s - 9 Mb/s for HDX — Full high definition 1080p resolution video and high definition audio
Over 9 Mb/s for 3-D HD movies
With the introduction of 4K Ultra HD TVs, you are beginning to see 4K resolution content become available via internet streaming. As listed above Netflix is streaming some content in 4K, but there are additional requirements with regards to both required internet speed and TV or media streamer hardware/software requirements.
Connecting Your Network Media Player to Your Home Network Must Also Be Fast
Remember that the speeds are measured at the device. This means that if you test your speed at the device and it is significantly lower than your internet speed plan, the problem could be in how you connect from the device to your home network router.
Connecting to your home network wirelessly can often be slower than connecting using a powerline adapter. Directly connecting your network media player to your router using an Ethernet cable is your best choice.
For the best high definition streaming video experience, use a power-line adapter or router that is labeled as an "AV" model. Expect new technologies to improve in-home connection speeds in the near future.
