The choice of the right video resolution is crucial for the quality of your productions. Often, discussions about videography only focus on the resolution without considering the various factors that play a role. In this guide, you'll learn what the common video resolutions are and how to record future-proof videos. Whether you're a beginner or an advanced user, knowledge about resolutions can elevate your videos to a new level.
Key insights
- Video resolutions are specified in pixels and have a direct impact on image quality.
- 4K is not the same as 4K – there are different standards (e.g., UHD and DCI).
- Full HD (1080p) can be sufficient in many cases and offers advantages in processing and storage.
- The frame rate and bit depth play an important role in the overall quality of a video.
Step-by-Step Guide
Step 1: Understanding Resolution
Start by understanding what resolution means. Videos consist of many individual images, called frames. Each of these frames has a specific resolution measured in pixels. A pixel is the smallest element of an image and plays a crucial role in color representation. To piece the images together in the right quality, it is important to know the resolution.
Step 2: Understanding Resolutions
The most common resolutions are 480p, 720p (HD), 1080p (Full HD), and 2160p (4K). For example, 480p stands for 720 x 480 pixels, which is considered standard definition. Full HD has a resolution of 1920 x 1080 pixels. Here, the number "1080" indicates the height, while the width typically measures 1920 pixels.
Step 3: Differences Between HD and 4K
When looking at 4K resolutions, it is important to differentiate between the terms UHD (Ultra High Definition) and DCI (Digital Cinema Initiatives). UHD has a resolution of 3840 x 2160 pixels, while true 4K (DCI) at 4096 x 2160 pixels represents the higher standard. This is especially relevant for films and professional productions.
Step 4: Considering Actual Image Quality
A high resolution does not automatically mean higher image quality. Sometimes, you can achieve better results with a Full HD camera than with a high-end 4K camera that does not provide the necessary quality in production. Ensure that the entire chain from the camera to editing to broadcasting is correct.
Step 5: Practical Application of Resolution
Use the resolutions to experiment and record different video formats. Full HD is perfectly adequate in many production scenarios, especially when it comes to processing speed and file size. The decision to shoot in 4K should be well thought out.

The choice of the right video resolution can often make the difference between a good and an outstanding video. Be aware that resolution is not everything, and also consider other factors such as frame rate and bit depth. Educate yourself about the different standards and choose the resolution that fits your project.
Frequently Asked Questions
What is the standard resolution for old TV broadcasts?The standard resolution was often 480p.
What is the difference between UHD and DCI?UHD stands for 3840 x 2160 pixels, while DCI has 4096 x 2160 pixels and is used more for cinemas.
Why shouldn’t I only focus on resolution?Image quality depends on many factors, including camera quality, lenses, and editing techniques.
Is it always better to shoot in 4K?Not necessarily. Full HD is often sufficient and can cause fewer problems in processing and storage.
How does frame rate affect video quality?The frame rate determines how smoothly a video plays and can significantly impact the perception of quality.
