![]() ![]() Some allow a wider 4K aspect ratio called C4K, or Cinema 4K, which measures 4096×2160 pixels, and some older models offer a lower resolution HD standard that records with 1280×720 pixels. Panasonic cameras offer a range of resolution settings though the most usual are 4K and Full High Definition (FHD). Were we shooting FHD the pixel count would be 1920×1080. The display here shows us that we are shooting 3840×2160 video, which is 4K. This is where you will see the resolution of your video in pixels. Interlaced video is usually recorded at 50i. For this to be effective the overall frame rate needs to be high so that the picture doesn’t flicker. In interlaced video every other line is played in sequence – all odd numbered lines followed by all even numbered lines. The ‘p’ in 25p stands for ‘progressive’, which means in the video all recorded lines of pixels are displayed at the same time. In cinema we usually see 24fps, and if we want to be able to slow down our footage to create slow motion effects – or simply want to show smoother motion – we might record at 50/60fps. You can see that this video is recording at 25 frames per second, which is pretty standard for countries outside the USA where they would use 30fps. This number represents the number of frames per second being recorded by the camera. Usually these days video is recorded in a 16:9 widescreen ratio, but we can also record in 4:3 when using a camera that has Anamorphic Mode. Here we can see the aspect ratio of our video. In full frame recording all the pixels are used to record the scene, but the resolution is downsized to fit the 4K or FHD choice of the videographer. This means each recording pixel is directly represented in the final output – and the extra cropping of the sensor area will make our lenses seem longer, which is great when you need a bit more length for a distant subject. So in 4K mode we’d use only 3840×2160 pixels of the 6000×4000-pixel sensor, and in FHD mode we’d use only a 1920×1080-pixel area. In this model we also have the chance to record ‘pixel-to-pixel’ – which means the area used is determined by the number of pixels in the resolution selected. If you need a frame rate above 25/30p in the Lumix S5 the area of the sensor used is cropped to APS-C. In this case the whole sensor is used to record, but not all choices allow full frame recording in most cameras. This section shows us the what area of the sensor that will be used for recording. In Lumix cameras the MOV format often has all the highest recording settings, and is aimed at those who will process their footage in software to eventually output it in a format suitable for viewing easily. Some cameras offer a wider collection of file types, such as the Lumix GH5s ![]()
