High frame rates are absolutely essential for good underwater video. Top-of-the-line video cameras record at 4K resolution and 60 frames per second (fps) or even 120 fps. The next most immediate specification to consider would be the frame rate that your video camera allows you to record in. Other cameras, especially high resolution cameras, may use pixel binning or line skipping to process the data from their sensor - resulting in slightly lower quality video.The worst video quality comes from cameras that “crop” the video by using only part of the sensor to capture footage. A sensor that has a one-to-one pixel readout (like the 12 MP Sony A7S III) will not downsample, but it will perform very well in low light as we mentioned before.

The most ideal camera sensor is one that has a full pixel readout from a 35mm sensor (often shooting the initial video in 6K) that will downsample to 4K, adding additional details to the video.
A higher resolution sensor also requires more processing. The Sony A7S III performs very well in low light because its sensor is "only" 12 megapixels. This is to keep every pixel on the sensor larger and collecting as much light as possible. Generally, a video oriented camera will actually have a slightly lower resolution than you might find in a photo camera. However, APS-C, micro four thirds, and even 1" sensors produce very respectable video. As with photography, larger sensor sizes, like a super35 sensor, allow you to capture more light resulting in better dynamic range and quality in low light. You also want to consider the size of your sensor and how your camera processes the data from your sensor. When you film in very high resolutions like 8K, you are able to crop your video substantially in post processing, providing you with additional "broll" perspectives.īut as with photography, there's more to video than just resolution. You may even want to consider a video camera that can record 6K or 8K. The good news is nearly every new DSLR, mirrorless or compact camera features 4K recording capabilities. To start, being able to record 4K video is now a standard that is expected out of any respectable video camera.
What makes the “Best Underwater Video Camera”? When shooting underwater video, or video in general, there are many factors to consider. Features to Look For in an Underwater Video Camera:
