Codec & Compression: It's natural to know that different codecs not only lead to the differences among video sizes, but also video quality.
So usually a 60dB S/N media player is preferred for a better quality.Ħ. It's just a parameter when choosing media players, influencing the output video quality to some degree. SNR: Signal to Noise Ratio (also SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. Given that, if you're gonna to watch videos on a 16:9 HDTV, you can make use of an aspect ratio converter to convert 4:3 to 16:9 aspect ratio for a better video quality.ĥ. If you watch a 4:3 video on a 16:9 screen, the video image will be squashed.
Aspect Ratio: It's more reflected on the video's display when playing video on Mac, iPhone iPad Android. Therefore, as you change video quality from high to low, you can omit the frame rate adjusting option, since it has little impact on quality.Ĥ. It influences more about the video's fluency rather than quality. Frame rate: Frame rate is the frequency at which consecutive images called frames are displayed in an animated display. So adjusting bitrate is an effective choice to change video quality.ģ. It means if there are two videos in same size, resolution and others, the higher bitrate one will be sharper and in better quality than the lower one. Bitrate: Firstly bitrate in proportion to file size of a video, reflecting the richness of the content.

You can compress 4k to 1080p, 1080p to 720p, or 720p to 480p according to your needs.Ģ. And different devices require different resolution to enjoy the video to its fullest, namely 640x480 for Apple TV or iOS devices 720x480 for Android Samsung, HTC 720x480 or 320x240 for Microsoft WP8, Xbox, Surface, Zune and Sony PS4, PS3, PSP etc. Resolution: The higher the video resolution is, the higher the quality is. Now let's go in depth of the key factors.ġ. In fact, video quality is not determined by a single element, but a result of various factors, such as resolution, bitrate, frame rate, aspect ratio, codec, compression ratio, data rate, SNR, interlace/progressive scan, etc. To solve it, you need to know what elements affect video quality first.

Well, how to change video quality? It's a big question, always stopping green hands from getting off the ground. Part 1: What Determines Video Quality? Resolution, Frame Rate, Bitrate, Codec or Any Other?
