Has video resolution always mattered? Or is it a phenomenon gaining importance after technological advancements?
Video resolution did not matter until technology upgraded with multiple grades of video quality. In the beginning of the 1900s, people perceived the quality of video to be good and they were amazed, even though it was poor in comparison to today’s standards. Over the years, this scenario has been completely changed.
In the current day, there are about 10 grades of resolutions from commercial to industrial use. The availability of options in video quality, downplayed lower grade qualities and demanded high quality. This shift is evident in the debate between HD vs SD TV, where standard definition has gradually faded in favor of superior clarity and detail. While technological advancements were vertical, multi-option qualities were horizontal innovation.
In this blog, we’ll explore the primary video qualities and their related concepts. Understanding this will help you render your VOD/OTT platform for better SEO ranking and eventually more website traffic.
Video resolution has undergone 7 major generations since 1888 from mechanical TV with 30 lines to 8K UHD with 33 million pixels.

Upscaling increases a video’s resolution by interpolating missing pixels. Advanced algorithms analyze the original pixel structure and predict new ones to enhance the resolution without distorting the image. AI and machine learning improve the quality, making the video sharper and more defined.
Upscaling Technologies
- Hardware Upscaling:
Built-in upscaling engines in devices enhance SD or 720p content to 1080p or 4K.
- Software Upscaling:
Editing software uses algorithms to upscale the resolution and reduce artifacts.
Pros:
- Improved viewing experience on HD or 4K screens.
- Older content is compatible with modern devices.
- Cost-effective for viewing content in higher resolutions.
Cons:
- Limited improvement, as it can’t add new details.
- Artifacts like blurriness or pixelation may appear, especially with lower-quality upscaling.
The difference between hd video vs sd video is crucial for content creators, as choosing the right aspect ratio and resolution impacts the viewing experience. While hd vs sd tv remains a deciding factor for many users, modern devices favor higher resolutions.
