Progressive scan is a method of displaying video where each frame is drawn line by line in sequential order. This creates a smoother and clearer image, especially in scenes with movement. It is commonly used in modern displays, digital video cameras, and live streaming platforms because it reduces motion blur and flickering.
This differs from interlaced scanning, an older method where frames are split into two alternating fields. In interlaced video, the odd-numbered lines of an image are drawn first, followed by the even-numbered lines. While this technique was useful in older television broadcasts to conserve bandwidth, it can cause flickering, jagged edges, and motion artifacts—issues that progressive scan eliminates.
Most modern cameras, monitors, and streaming platforms prioritize progressive scan because it produces a sharper, more stable image, making it ideal for live streaming services, worship music, and speaker presentations.
How Progressive Scan Video Improves Streaming Quality
One of the biggest advantages of progressive scan video is its ability to maintain image clarity even at lower bitrates. This is particularly important for live streaming, where bandwidth limitations can affect quality. Progressive video compresses more efficiently than interlaced video, allowing for a better balance between quality and file size.
Those using Resi’s Resilient Streaming Protocol (RSP) can take full advantage of progressive scan. RSP is designed to deliver high-quality streams without buffering or dropped frames, even in unpredictable network conditions. When combined with progressive video, this results in a smooth, uninterrupted viewing experience for online audiences.
Progressive scans also reduce the risk of compatibility issues. Many online streaming platforms, including YouTube and Facebook Live, prefer progressive video formats. Choosing progressive scan from the start helps avoid problems with playback or video conversion later on.
Progressive vs. Interlaced Scanning
When deciding between progressive vs. interlaced scanning, a progressive scan is usually the better choice for live streaming. Progressive video produces a cleaner image with fewer visual artifacts, which is particularly noticeable when capturing motion, such as a pastor walking across the stage or worship members playing instruments.
Interlaced video, on the other hand, can introduce issues like screen tearing or flickering, especially when displayed on modern digital screens. Since nearly all smartphones, tablets, and computer monitors display video progressively, using interlaced scanning can lead to a lower-quality experience for online viewers.
Because of these benefits, most organizations streaming with Resi use progressive scan to maintain high-quality video output.
Choosing the Right Settings for Progressive Scan Streaming
To make the most of progressive scan, consider the following recommendations:
- Set Your Camera to Progressive Mode – Most modern cameras offer a progressive scanning option (often labeled as “1080p” or “720p”). Avoid interlaced modes like “1080i” unless absolutely necessary.
- Match Frame Rates to Your Streaming Needs – A frame rate of 30fps (frames per second) is standard for streaming, providing a good balance of smooth motion and file size. For fast-moving worship environments, 60fps can offer even better motion clarity.
- Use a Compatible Streaming Encoder – Resi’s streaming encoders support progressive scan video, optimizing it for smooth, high-quality streaming.
- Check Display Compatibility – Since nearly all modern devices support progressive scan, your audience will see a cleaner image on their phones, tablets, and smart TVs.
By following these steps, it is possible to create high-quality streams that look great on any screen while minimizing technical issues.
Choosing progressive scan video for live streaming helps deliver a more professional and engaging experience for your congregation. Compared to interlaced scanning, progressive video can produce sharper images, smoother motion, and better compatibility with modern platforms.
Organizations using Resi’s technology benefit even further, as Resi’s streaming solutions support high-quality progressive scan video while preventing buffering and playback issues. By selecting the right video settings and using reliable streaming equipment, it is possible to create polished, high-quality broadcasts that effectively share their message with online audiences.
