Features to Look For in an Underwater Video Camera:
What makes the “Best Underwater Video Camera”? When shooting underwater video, or video in general, there are many factors to consider. To start, being able to record 4K video is now a standard that is expected out of any respectable video camera. The good news is nearly every new DSLR, mirrorless or compact camera features 4K recording capabilities. You may even want to consider a video camera that can record 6K or 8K. 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.
But as with photography, there's more to video than just resolution when considering the best underwater video camera. You also want to consider the size of your sensor and how your camera processes the data from your sensor. 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. However, APS-C, micro four thirds, and even 1" sensors produce very respectable video. Generally, a video oriented camera will actually have a slightly lower resolution than you might find in a photo camera. This is to keep every pixel on the sensor larger and collecting as much light as possible. The Sony A7S III performs very well in low light because its sensor is "only" 12 megapixels. A higher resolution sensor also requires more processing. 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 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. 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.
The next most immediate specification to consider, for the best underwater video camera, would be the frame rate that your video camera allows you to record in. Top-of-the-line video cameras record at 4K resolution and 60 frames per second (fps) or even 120 fps. High frame rates are absolutely essential for good underwater video. This is because three dimensional underwater environments produce a lot more camera shake in a scene than topside video. Unless you have a tripod, you need to capture your video at higher frame rates and slow it down in post processing to get stable footage. We recommend that serious underwater video shooters consider frame frates as being the most important specification in their chosen camera.
Finally, you will want to consider the codecs, bit rates, bit depth, color sampling, and picture profiles that your video camera can record in. Codecs are algorithms that compress your video data into a certain file type. The bit rate of your video is the amount of data that gets recorded from your system over a given time period. Some cameras can record at higher bit rates onto internal memory and some require external recorders to film at higher bit rates. Bit depth is the number of color options your camera can record with. With modern cameras, if you want to color grade in post processing, you should aim to record at 10-bits or higher. Color sampling refers to how accurate the color capture on your camera is by the number of pixels it chooses to determine the color in a square area of your image. If you are color grading than you will want a camera that can record 4:2:2. If you are not color grading then 4:2:0 is acceptable. Finally,picture profiles are algorithms that "bake-in" data into your video file resulting in a certain "look" to your video. Log profiles can be particularly useful for color grading because they save details from the highlighs and shadows of your image - much like a "poor mans" RAW file. If you post-process heavily, then you will can to consider a camera that can record RAW filetypes including ProRes RAW and Blackmagic RAW. These are uncompressed formats that maximize the information gathered by the sensor and provide you with extended flexibility when it comes to color grading and post-processing.
It is important to note that many cameras record at higher bit rates, deeper bit depths, and sometimes with RAW or Log file types with an external recorder, like the Atomos Ninja V external recorder. Nauticam offers a housing for the Ninja V for use with your underwater system.
Other factors to consider when choosing an underwater video camera are in-body image-stabilization (IBIS), autofocus capability, low light sensitivity, lens options, and, well, of course, the price tag.
If you're looking to step up your game and ensure reproducing the colors and beauty of the underwater world, make sure to also choose the right underwater camera light.
Here we will walk you through some of the key points that make each camera great for underwater video and hopefully make the process of choosing which underwater video camera is best for you, a little bit easier.
