To give you the best viewing experience possible on web, we automatically adjust the quality of your video stream from standard definition (such as 240p or 480p) to high definition (720p or 1080p), based on the speed of your Internet connection (bandwidth). This is why you may notice that the quality of your video changes and fluctuates 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 video streaming, there’s a chance your internet connection is unstable.
Manual video settings are not available for the HTML5 player. Viki will automatically adjust video quality based on the strength of your network connection.
If you're having issues with your video quality, please follow these steps.
