4K Cameras For Video Buyers Guide
Below you’ll find all of the relevant factors to consider when looking at 4K-capable devices.
Why shoot 4K video?
But, first, why even shoot 4K, especially if you don’t own a 4K capable TV or monitor. Well, the main reason is that downsampling or reducing the resolution to 1080p full HD will create more detailed videos. And the images will look more crisp, sharp, and vibrant. And given 4K offers 4x the resolution of 1080p, you have plenty of leeway for creative reframing and cropping without losing detail. Or you can apply aggressive digital stabilization to reduce shake.
The only real downside of 4K is the file size, which is often 5x or more that of a similar 1080p video. So you’ll want to get a 64 GB SD card to ensure you have enough storage space. Shooting at this resolution also does highlight more blemishes and imperfections in the skin. And those aren’t as visible at lower resolutions. So you may have to readjust your lighting to hide these details if you find them problematic.
The first consideration, though, above all else, is sensor size, as it ultimately determines image quality. And if all things are equal, a larger sensor will always outperform a smaller one. So if you want the best image quality available, it’s important to look for a device using a full-frame sensor. There you’ll get the best low light performance, a shallow depth of field, and a better signal-to-noise ratio. Otherwise, for many videographers, an APS-C sensor would be plenty sufficient.
Resolution & Frame Rate
You’ll find most devices offering 4K UHD 30 FPS as their standard maximum. But, you can find plenty of options with the wider 17:9 aspect 4K DCI resolution. And if you look at the higher-end market, you’ll also find some models offer 60 FPS or higher, too. Even so, for most users, 4K UHD 30 FPS is sufficient. And the only real reason to opt for a higher frame rate is if you specifically want to shoot oversampled slow-motion video. Otherwise, there’s no reason to opt for such models as you’ll be paying quite a premium for this capability. So save the money and invest in other accessories instead.
Note: Several devices shoot 4K 60 FPS or higher using the HFR (High Frame Rate) or SNQ (Slow & Quick) Mode. Doing so lets them capture slow-motion video rendered internally. The problem is that these modes only last a few seconds before buffering, so proper timing is key. And they generally result in a loss of image quality and fine detail, as they have low bit rates. Finding a device that records at this frame rate natively will provide better image quality. And it’s something to consider if you want the highest quality recording available and better flexibility.
Bit rate is how much data is encoded or writen per second. The higher the bit rate, the better the final video, so long as all else is equal. Thus, a higher bit rate device will produce better images than one with a lower bit rate. Generally, though, most devices record using 100 Mb/s as standard. Thankfully, you can find plenty of models recording with 400 Mb/s or higher, giving you higher quality footage. Even so, 100 Mb/s is a good balance between image quality and file size. And for most applications, you won’t see the benefit of a higher bit rate, as the differences are subtle.
You can find these devices recording with either 8 or 10-bit. But, 8-bit is the most common. Bit depth is the video’s color range and how many colors are possible in a single image. The higher the bit depth, the more colors are possible and the more nuanced the rendering. For this reason, 10-bit will capture better color shades and hues than 8-bit. So if color grading is an important part of your workflow, look for devices recording with 10-bit color. Otherwise, 8-bit will be enough for most applications.
It’s important to know whether the device you’re considering records at full sensor width or has a crop in 4K. Not all devices create 4K video the same way. And the last thing you want is to have an unwanted magnification when switching from 1080p, as it’ll directly affect framing.
Some devices don’t offer confident autofocusing when recording in 4K. So investigate how the particular device performs when recording at this resolution beforehand.
You may also want to consider opting for a device with a fully articulating screen, as it’ll make framing your video easier.
Flat Picture Profile
Flat color profiles or log profiles capture more data and improve the dynamic range and color fidelity. Doing so gives you more freedom to edit and color grade, bypassing some of the internal limitations. And it’s a good option to look out for if you plan on editing the footage heavily in post-processing.
