The Quest for High-Resolution Video: Current Limits and Future Possibilities
As of August 2023, the pursuit of a 50 megapixel video camera remains largely theoretical. Consumer video cameras, while continually advancing, still fall short of this target. Let’s delve into the current landscape and explore the possibilities for the future.
Current State of Consumer Video Cameras
Most high-end consumer video cameras are currently capable of recording at resolutions around 4K, approximately 8.3 megapixels, or 6K, around 21 megapixels. These resolutions are a far cry from the 50 megapixels seen in high-resolution still cameras, such as mirrorless and DSLR models. For instance, the Canon EOS R5 and Sony A7R IV can achieve stunning still image quality but their video capabilities are limited.
While manufacturers are pushing the boundaries of resolution in still photography, the focus in video recording is different. Professional cinema cameras prioritize frame rates, dynamic range, and color science over sheer megapixel count. This means that even as still cameras continue to inch closer to 50 megapixels, video cameras are optimized for entirely different specifications to meet the demands of motion picture production.
Understanding Video Resolution
Video resolution is not measured in megapixels, but in terms of resolution and refresh rates. A common designation is 1080p30, indicating a resolution of 1080 on the short dimension (typically 1920 on the long dimension) and 30 frames per second (fps). The P stands for progressive scan, as opposed to interlaced (i).
The television industry is currently in the 4K phase, which is four times the resolution of 1080p, measuring 2160 x 3840 and resulting in a megapixel count of around 8.2. The next frontier, 8K, measures 7680 x 4320 and boasts an incredible 33 megapixels. The high-resolution nature of 8K means that a single HDMI cable cannot handle the data; multiple cables and special TVs are required to view it.
Future of High-Resolution Video
As of now, the highest resolution video is captured by the Phase One, which can shoot in 10K, bringing us to around 50 megapixels. While consumer 8K is expected to become more accessible within the next few months, the commercial sector typically has superior equipment, indicating that 10K or even higher resolutions are possible in the future.
Manufacturers like Canon are already making strides in this direction, hinting that 8K cameras could soon be more affordable for the average consumer. However, the rapid advancement of technology means that what seems impossible today could be a reality tomorrow.
