Video Resolution Explained: 480p, 720p, 1080p, and 4K

Direct answer: Resolution is how many pixels make up your picture. In Descript’s export options you will see choices like 480p, 720p, 1080p, 1440p, and 4K. Higher numbers mean sharper images and larger files. For most beginner videos, 1080p is the sweet spot—do not go below 1080p for polished work; consider higher only for big TVs or when your camera and screen can actually use it.

This guide is grounded in the Descript Made Easy lesson “Video Resolution — What are 480, 720, 1080p, 4K?” Export from a project at web.descript.com.

What do 480p, 720p, 1080p, and 4K mean?

1. The number is pixel height — Roughly how many dots of color run vertically (480, 720, 1080, etc.). More pixels = more detail.
2. Descript’s export ladder — The lesson walks through exporting the same video at each available resolution so you can see quality and size tradeoffs.
3. 4K is the top end — Maximum detail and maximum file size / render time.

How should beginners choose a Descript export resolution?

1. Default to 1080p — Looks good on phones, computers, and most TVs. Best everyday tradeoff.
2. Do not go below 1080p for finished work — Lower settings look soft/pixelated on modern screens.
3. Consider higher than 1080p only if the video is meant for large screens and your source camera / monitor can use the extra detail. Exporting 4K from 1080p source footage does not magically add detail.
4. Test on real devices — Export a short sample, watch on phone, laptop, and TV, then decide.

How to try resolutions in Descript

1. Open your project and click Export.
2. Open the resolution dropdown.
3. Compare options (480p through 4K / max).
4. Export a short test at 1080p first.
5. Only bump higher if you have a clear large-screen need and capable source media.

FAQ

Is 720p “HD enough”?
The lesson’s practical advice for finished beginner work is: stay at 1080p or above.

Does 4K always look better?
Only if source and display can use it. Otherwise you mostly get bigger files and longer exports.

What if my camera only shoots 1080p?
Exporting 4K will not invent detail that was never recorded.

Where do I change resolution?
In the project Export dialog’s resolution menu.

Is 1080p OK for YouTube and social?
Yes—1080p is the everyday recommendation in this lesson.
