To give you the best viewing experience possible on your iOS device, we automatically adjust the quality of your video stream from standard definition (such as 240p or 480p) to high definition (720p), based on the speed of your Internet connection (bandwidth). This is why you may notice that the quality of your video changes as you watch videos. Here are some other factors that determine video quality:
- Video player size: By default, the quality setting will be on “Auto” and we'll use the highest quality based on your video player's size.
- Quality of the original uploaded video: For example, if the video was encoded in standard definition, it will not be available in high definition.
- Internet connection speed and reliability: By default, Viki is set to change video resolution automatically, depending on your Internet connection speed, whenever you watch a video. Automatic resolution settings can cause problems, if you have an unstable Internet connection that's constantly speeding up or slowing down.
Please keep in mind that your Internet service provider (ISP) could be the culprit of your speed fluctuation issues. If you're experiencing slow loading or poor quality on your iOS device (iPhone, iPad, iPod), there’s a chance your internet connection is unstable.
- Wi-Fi Vs. Cellular Network
You may want to test video quality on both a Wi-Fi signal and a cellular signal to see if you experience different results. This will help narrow down what might be causing the streaming issue.
- Change Your Quality Setting
There is currently no option to change quality settings from the Viki app. The strength of your internet connection will dictate the quality of the video. Simply put, as your connection fluctuates, so will your video quality.
- Run a Speed Test
Depending on your connection, internet speeds can vary by the second. To test your current network speed, try using an app like Speedtest.net from the App Store. We recommend at least a 2.0 Mbps internet connection for streaming video.
- Restart your Wifi connection
- Unplug your router or modem from its power outlet (don’t just turn it off).
- Wait 15-20 seconds, then plug it back in.
- Allow the device a minute or two to turn back on.
It may seem simple, but doing this can solve many connection problems without the inconvenience that comes with resetting your modem or router.
There are, of course, some times when you’d want to reset your router or modem and start back at square one, but for most cases, simply power cycling the device will do the trick.
