Sometimes forcibly upscaling a video may destroy the image quality. Does up-converting resolution make video clearer? The higher the resolution, the more the pixels and the better the video quality. In digital imaging, resolution equals to pixel count. How does resolution affect video quality? 1080p means a video composed of images with 1080 horizontal lines from top to bottom, each of which is 1920 pixels wide. There is no "video resolution" term on Wikipedia. So when we say video resolution, we actually mean image resolution. Bit depth - decides color accuracy of videoĪ video is a continuous display of a group or groups of still images at a certain speed. Bit control mode - controls balance between quality and size Codec - determines compession ratio and affects video quality Bit rate - affects video quality and decides video size Frame rate - impacts the smoothness of video Resolution - decides the quality of every single image in video Instead of a large chunk of dizzy words, we list all must-know information for you one by one as follows. ![]() Here we will focus on explaining the main factors that affect a compressed video quality, making it easy for you to know how to mediated these video parameters with a video processing software to control video quality. If what we are talking about is visual quality, real-world viewing conditions should be counted in as well, for example, the viewing angle and distance, display size/resolution, decoding ability of video player, lighting, etc. The quality of an encoded video also depends on video codec, bit control mode and bit depth. What are the factors that affect or decide video quality? Video resolution, bit rate and frame rate are taken as the correct answers everywhere. That's because the quality may be dropped in the every step before finally showing on HDTV screen, from upload to download, transfer to airplay, edit to convert and more. Apparently, the perfect match of huge screen and ultra high definition leads to the best-ever immersion, which is so hard to reach at home. Why do so many people prefer IMAX movies despite the ticket always running $5 or $6 higher than that of a regular film? Guess the answer will be as simple as it is worth every penny. And the reason for "maybe" is that it can be prevented visually when conducting in a proper way with a prefessional-level video encoder.įree Download for Mac OS X 10.6 or later What Factors Affect Video Quality? That's what encoding is designed for, to clear redundant information as much as possible. ![]() Technically, there is no way to 100% avoid loss of data when compressing or transcoding a video. What are the factors that affect or decide video quality? ![]() Video resolution, frame rate, bit rate, codec, bit control mode (macroblock), Bit depth (color depth). The factors that decide a compressed video quality include: The factors that determine the quality of an uncompressed videos are: video resolution, video frame rate and macroblock.Ģ.
