Facebook Video Quality Explained: HD, SD, File Size, and the Best Format to Choose

HD vs SD

HD gives a sharper image and is best for large screens or videos you want to keep. SD is smaller, downloads faster, and is usually fine for a phone screen or a quick share.

File size

As a rough guide, one minute of HD video can be several times larger than the same minute in SD. If storage or mobile data is limited, SD is the practical choice.

Reels, Watch videos, and live replays

• Reels: short and vertical, so HD is usually affordable in size.
• Watch videos: choose HD when the quality of detail matters.
• Live replays: often long, so SD can save a lot of space.

Which should you choose?

Pick HD for archiving and bigger screens. Pick SD for phones, slow connections, or long videos. If you are unsure, download SD first and only repeat in HD if you need better quality.
