Unless youĬonfigure the encoder in a way that ignores some or all of the Likely to have compressing the image to the same degree. The more variability-such as noise-there is in the image, the moreĬomplex the compression process and the less success the algorithm is Need to drop details to achieve the same level of compression. Variability generally makesĬompression more difficult, resulting in more lost quality due to the

Picture noise (such as film grain effects, dust, or other grittiness to For thisĪnd other reasons, the more motion there is in a video, the larger the The complexity introduced by motion results in larger intermediateįrames due to the higher number of differences between frames). These differences are, and the less effective the compression is atĪvoiding the introduction of artifacts into the compressed video. The more successive frames differ from one another, the larger

Some details may be lost the amount of loss depends on the codec and how it's configured, but as a general rule, the more compression you achieve, the more loss of detail and fidelity will occur. Most video codecs are lossy, in that the decoded video does not precisely match the source. Just as audio codecs do for the sound data, video codecs compress the video data and encode it into a format that can later be decoded and played back or edited. Not only is the required storage space enormous, but the network bandwidth needed to transmit an uncompressed video like that would be enormous, at 249 MB/sec-not including audio and overhead.
