Understanding Video Resolution and Quality

At Qbrick, we continuously push industry standards to ensure the highest possible maintainable quality of customer-uploaded video content, whether it’s for showcasing, promotional purposes, or archival storage.

While we offer standardized encoding profiles designed to perform reliably across global use cases, we understand that every organization has unique needs. If you have questions about your content or believe there may be room for optimization, we encourage you to contact us. Together, we can tailor a solution that best supports your company’s goals and audience.

As a side note, video quality is ultimately subjective. Viewers consume content under different conditions, on different devices, and with varying expectations. What is considered “high quality” in one context may not be necessary, noticeable for another.

In this article, we’ll provide a high-level overview of:

• Why encoding is important

• What we provide

• How encoding decisions affect the end viewer

Why do we encode Video?

Whenever you record a video whether it’s a concert on your phone, a studio production, or a screen-recorded presentation you typically end up with a single large video file. Different devices generate different formats, codecs, and resolutions.

Video encoding (sometimes referred to as video conversion) is the process of converting that original file into a standardized format that is:

• More data-efficient

• Optimized for distribution

• Compatible across devices and platforms

Modern encoding does more than simply compress individual pixels. It analyzes frames in sequence, identifying movement, color changes, and repeating patterns. By understanding how frames relate to one another, encoding can significantly reduce file size while maintaining perceived visual quality.

In many cases, file size can be reduced dramatically without noticeable impact on viewing experience.

Transcoding and Adaptive Delivery

As part of the encoding process, we also perform transcoding, creating multiple renditions of the same video at different quality levels.

This enables adaptive streaming.

For example, imagine someone watching your video on a moving train that enters a tunnel. Since most online video is progressively downloaded during playback, a full-resolution stream may begin buffering due to reduced bandwidth. In this case, the video player automatically switches to a lower-bitrate version to maintain smooth playback.

Another example: a viewer may start watching a studio-recorded podcast but then lock their phone and continue listening with the screen off. Delivering full 1080p or 4K video in that scenario would be unnecessary data usage.

A typical transcoding profile may look like this:

Resolution and Bitrate

Resolution refers to the videos canvas size, this is the total amount of on display pixels each video frame is being drawn on. This is usually represented in the 16:9 aspect ratio and the "p" stands for the vertical pixel count.

A common misconception is that resolution alone determines video quality that UHD will always look better than HD.

In reality, resolution is only part of the equation. If there is not enough data (bitrate) to properly support a higher resolution, the result may look worse than a lower-resolution video with a higher bitrate.

This is why a 1080p Blu-ray often appears sharper and cleaner than a 4K stream from a heavily compressed streaming service.

Bitrate refers to the amount of data used per second of video and is typically measured in kilobits per second (kbps) or megabits per second (Mbps).

Different types of content have different bitrate requirements:

• A static interview setup requires less data.

• Fast-paced sports footage requires significantly more.

• Detailed textures or fine patterns demand higher bitrates.

If bitrate is too low, compression artifacts may appear. These can include:

• Text blending into backgrounds during sports broadcasts

• Fine clothing patterns becoming distorted

• Blocking or smearing during fast movement

• Loss of detail in complex scenes

   

  

   

Many streaming platforms limit higher bitrates or place them behind premium tiers due to bandwidth costs. This is why it’s important to define encoding profiles that align with your content strategy and audience expectations.

If resolution is the canvas, bitrate is the paint budget.
A higher bitrate -> more data per second -> more detail preserved after compression.

Framerate

Framerate, often abbreviated as FPS (frames per second), determines how many images are displayed each second.

Traditionally, broadcast television used:

• 24 fps (cinematic standard)

• 25 fps (PAL regions)

• 29.97 fps (NTSC regions)

Today, online content is commonly distributed at 30 fps or 60 fps.

Higher framerates:

• Capture fast movement more clearly

• Feel smoother and more responsive

• Are preferred for sports, gaming, and dynamic content

Lower framerates:

• Provide a cinematic aesthetic

• Reduce overall data requirements

• Can be more efficient for certain types of content

There is a close relationship between framerate and bitrate. Doubling framerate generally requires roughly double the data to maintain the same visual quality.

Conclusion

Encoding, storage, and online distribution is always a balancing act.

The goal is to preserve the intended visual quality while maintaining efficiency in storage and bandwidth usage. Achieving the right balance depends on content type, audience behavior, device usage, and distribution goals.

There is much more to this field, including diminishing returns at higher bitrates, video containers, codecs, HDR workflows, and advanced compression techniques. Many excellent technical resources online explores these topics in greater depth.

In today’s digital landscape, where video represents a significant portion of online communication, making informed encoding decisions is not just a technical concern, it’s a strategic one.

At Qbrick, we are here to help you make those decisions with confidence.
