![]() You do, however, get a massive advantage if the playback resolution is lower than the resolution used to record a video clip. The same is true if you play a Full HD movie on a larger 4K display it will look softer than a clip that’s been recorded in 4K. This is because you’re simply blowing up a smaller image to fill the Full HD display. For example, if your movie is going to be displayed in Full HD, and you’ve recorded clips in Full HD, then any crop you make in post-production will make the image look softer. When it comes to videos, the resolution your films will be played back in dictates how much cropping freedom you get in video-editing software. You can make the subject look bigger in the picture or fine-tune the composition, while still retaining enough resolution to produce large, detailed prints. With still images, more pixels give you more flexibility when it comes to cropping. The EOS R5 will also offer full-sensor-width 8K video, making it easier to achieve the ‘cinematic’ image that comes from combining a full-frame sensor with a large aperture to create a shallow depth of field.ĭigital crop: 4K video has four times the pixel density of Full HD so you can crop to a tighter Full HD composition. The chief drawback is that you can end up with a little less detail. ![]() The camera then processes the image to reduce it to the correct 4K resolution. Here, the full width of the image sensor is used to shoot an image, with the height of the image being cropped to give the correct aspect ratio for video playback. The shot becomes more magnified if you activate ‘Movie digital IS’ to reduce camera shake.Ĭanon offers ‘uncropped’ 4K recording in a few cameras, including the EOS 90D and EOS M6 Mark II. It’s also a pain when you want to quickly move from shooting photos to video, as the framing will change. This is good if you’re filming wildlife, but less useful if you want to capture a wide view. While this gives sharp results and puts less pressure on the camera’s sensor than other options, it effectively increases the focal length of the lens. ![]() This is used for 4K capture in the EOS 5D Mark IV, EOS R, EOS RP and EOS 250D. The simplest option is to use a 1:1 pixel crop, where a 3840x2160 (or 4096x2160) pixel portion in the middle of the sensor is used, and the rest of the sensor is ignored. Reducing the pixelsĬanon EOS camera sensors are packed with millions more pixels than are needed for 4K video recording, so Canon have employed different methods to deal with this disparity. More pixels gives you more clarity, smoother edges, and more creative editing options. There are four times the number of pixels in an 8K image than there are in a 4K one, and 16 times the number of pixels in an 8K image, compared to a Full HD image. This is ‘only’ twice the horizontal and vertical resolution of 4K, which in turn is twice the resolution of Full HD. Full HD is also known by its vertical resolution – ‘1080p’ – while 4K gets its name from its horizontal resolution.Īn 8K image is built from 7680×4320 pixels. It’s the same principle with 4K, although Canon uses two different flavours of 4K each frame is either 4096x2160 pixels (4KI DCI) or 3840x2160 (4K UHD). A Full HD image is always 1920 pixels wide and 1080 pixels high, whether it’s recorded with a 24Mp EOS 2000D or a 50.6Mp EOS 5DS. Video resolution doesn’t change in the same way. Full HD – 1920x1080 pixels: The revolutionary Full HD format now seems tiny!ĤK UHD – 3840x2160: 4K has four times the pixel density of a Full HD image.ĨK– 7680x4320: 8K has 16 times the pixel density of a Full HD image.
