To make Skype HD (high-definition) video calls, you will need a good HD webcam, a powerful enough computer, and sufficient bandwidth, which means you will need an internet connection fast enough to transfer the majority of video frames in high quality. In this guide, we will discuss how much bandwidth you need and how to achieve the best call quality.

High Definition video uses a lot of data. The video is a stream of high-quality images that pass before your eyes on the screen at a rate of at least 30 images (technically called frames) per second. There is usually some (or a lot of) compression that reduces data usage and prevents lag, but if you want high definition video, compression won’t work.

Skype is one of the VoIP apps with high video quality. Skype uses special codecs and other technologies to deliver sharp images and high-quality video, but it comes at a cost.

Therefore, even if you have all the necessary equipment for HD video calling with Skype, but not enough bandwidth, you will never get a clear, sharp and crisp HD video quality. You may even fail to have a decent call. Frames will be dropped and the audio, which is more important than the visuals in a call, may also suffer. Some people choose to disable their webcams and sacrifice the video for a clean call.
