What is SD?
SD—or Standard Definition represents the standard resolution level for streaming. 480p is the standard cut-off or base resolution for SD videos—with 480 referring to 480 pixels across a single image and "p" indicative of a progressive scan. While you can stream video at resolutions below 480p—for instance, 144p, 240p, and 360p—SD provides decent video quality and is considered an accepted standard in live streaming.
- 480p provides decent image quality without buffering or lags, even if you have a poor internet connection.
- SD resolution ensures a smooth viewing experience without significant lags or buffering.
- It is considered an ideal choice where network conditions are not favorable.
- It doesn't require significant storage space when compared to HD formats.
- SD is unsuitable for large screens, given its poor resolution and video quality.
- SD video quality further deteriorates based on the availability of bitrates.
- It is not suitable for videos that have fast-action scenes.
SD vs. HD
