![]() The higher the bit depth, the more tones of color possible for an image. Color is just the blending of the RGB channels, represented as data during the encoding process.Ī spectrum graph showing the tonal range of colors. The colors are encoded to create one pixel that contains the amount of RGB from each channel to represent the color. Each pixel contains 3 channels that represent the colors RGB (Red, Green, Blue). The bit depth determines the amount of color that the camera can recognize and encode. When capturing an image, an important consideration is the bit depth your CODEC in your camera is capable of. The CODEC also performs processing the color and details information to present the final quality that users see on their display. The CODEC compresses the digital content from the source and then allows users to decompress the content for viewing. The file is too large for content distribution, so the CODEC compresses the file to a smaller size. This is because the original file is usually in an uncompressed format that cannot be easily viewed or distributed on different devices. The CODEC’s main function is to convert the content’s original file to a smaller format for content distribution or media. We will begin with the CODEC’s function, and then delve into calculating the estimated storage from the bit rate manually to have a better idea of the content’s image quality and file size. The CODEC helps determine the quality of the captured content, but we need to know the bit depth and bit rate to have a better understanding of file size for storage considerations. CODECs work behind the scenes to process the captured image using programmed algorithms.Ī camera that supports Apple’s ProRes CODEC. Another type of CODEC can be implemented in software (intermediate CODEC) like Apple’s ProRes, used in post editing (used for final format delivery). The CODEC itself resides inside the camera’s firmware chip, and performs its function without requiring user intervention. An example of this would be the H.264 CODEC used in Canon 5D Mark II and Mark III cameras. The CODEC is often included as a camera feature. JPEG for still images and MP3 for audio). We are going to discuss CODEC in terms of video, since there are other types used for different purposes (e.g. ![]() This is in relation to the CODEC, which is the compression/decompression hardware (or software) that helps determine the quality of the images in your content (i.e. When preparing to shoot video during production, taking bit rate into consideration is important to determine file size and image quality. ![]() Bit rate refers to the amount of digital data encoded per unit of time, usually expressed in seconds to minutes. editing) requires understanding the relationship between bit rate (also spelled bitrate) and its CODEC.
