I figured out that I wasn't getting full resolution because they're video frames, and the frame rate was set at max. Still only 1k...



Actually, your 1920 x 1080 (a.k.a. 1080p) pixel dimensions are nearly the same as theprojection systems still used in most movie theaters. 2K is 2048 pixels wide 1080p is 1920 pixels wide . See image below for relative size.But as I've said before, pixel dimensions are only 1 measure of quality. There are many others. For example, 2K cinema projection typically uses Wavelet compression , while 1080p still uses DCT . Also, most 1080p consumer cameras use 4:2:0 chroma subsampling , while 2K uses full 4:4:4 chroma . In addition, 2K projection typically uses 10 or 12 bits per pixel, while consumer grade cameras nearly all use only 8-bit color depth And obviously, the quality of the camera's specific lens and sensor can make a huge difference, especially in poor lighting. But with good lighting, camera differences are less apparent.I really believe 4K video is over-rated. A professionally produced 2K or 1080p video up-sampled on a 4K TV will usually look better than a consumer quality 4K video, especially if it's been compressed to fit on a consumer SDHC flash card. To get better quality, you need to record at a much higher bit rate. For example, professional 1080p cameras often record at 200 Mbits/sec. For consumer cameras, you can also use the HDMI output to record onto SSD drives using an external recording device. Many of these also double as a 7" monitor and XLR microphone interface, like this
