Some common factors that influence video quality include:
- a high quality source video
- proper encoding
- high resolution
- a quality media player
- a quality screen
How video encoding impacts video quality
When a video is uploaded to the ScreenScape service, we accept any number of different source formats, resolutions, and codecs that our users may have available. In order to use these source videos, we take them and ‘encode‘ them to a common format that will be used by the rest of the system.
Why would I need to know about encoding settings?
The closer an uploaded video is to the final encoded video, the less chance there is for a loss of quality during translation. If you observe excessive pixellation or loss of video quality after uploading a video to ScreenScape, we recommend uploading a version of your video that’s as close as possible to the published encoding settings.
When considering video encoding, the factors that have the most impact on video quality:
- Bit Rate
- Encoding efficiency
Here’s a solid overview of how video encoding works, along with some of the available tools for re-encoding videos yourself.
