High resolution of sound is important especially for people who are interested in music. The quality is defined in terms of bitrates, which is the number of bits processed per unit time. To understand this concept better, the bitrates of each music source are compared:
For a music CD, the bitrate is 1411 kbps and for online sites, such as Spotify and iTunes, the bitrates are lower, 320 kbps and 256 kbps respectively. The reason for decreasing the sound quality stems from the fact that compressed versions of sound is easier to download and achieve, wherever you are (2). Even though these companies decide to decrease the quality of the audio for the sake of accessibility, this results in dissatisfaction from certain customers.
Youtube Sound Quality 360p Vs 480p Resolution
For YouTube, this sound quality is even lower compared to the other online music streamers. YouTube used to stream audio and videos all together, which would result in lower audio quality as the video quality becomes worse. For example, in 2012-2013, YouTube used 192 kbps audio bitrate for videos with resolutions higher than 720p, but the audio bitrate decreased down to 64 kbps, for videos with 240p resolution.
Nowadays, YouTube streams the audio and the videos separately, and so that the audio quality is not affected from the change in video resolution. Now, this quality depends on the device and its connection performance. The audio bitrate is around 126 kbps, which is considerably poor compared to the other sources of audio. (3)
Change the resolution of the video you're watching by clicking the gear icon and selecting a setting. Choose from 1080p, 720p, 480p, 360p, 240p and 144p. You cannot choose a high-definition setting if the video you are watching was uploaded in standard definition. The video will stay in the resolution you select for its entire duration, unless you manually change it.
When you're logged in to your YouTube account, you can change the default resolution setting by navigating to the Settings page. If your Internet speed is slower, select "I have a slow connection. Never play higher-quality video" and click "Save." YouTube will default to SD resolution whenever you play a video. For faster Internet connections, select "Always play HD on fullscreen (when available)" and click "Save." YouTube will automatically display videos in HD whenever the option is available.
This longer version is needed because all new YouTube uploads use separate audio and video streams. If you had used -f 'best[height=480]' only, it would work for low-resolution modes (e.g. 360p), but often wouldn't find any combined high-resolution stream at all.
yeah it's fake 320, but with this method, I get really clean sound from let's say monstercat videos (for the test) and because i got the original files from their bandcamp, I can say the comparison is held really well (the highs are a bit lower and the sound is not as crispy but that comes from youtube's compression...
Speaking of resolution, your data speed has to be in a specific range or within the byterate for streaming at that particular resolution for your video to stream in that quality in Auto mode. Starting from the lowest video quality that is on Youtube, we will be looking into how fast your data connection needs to be for each of the video qualities.
In video or digital photography, the resolution is the ability of a video or digital camera to record details, such as the number of pixels and their size. The video resolution is one of the few technical aspects of video quality that you can easily understand. You can think of resolution as a long string of numbers. The more numbers, the more detail, and the clearer the video will appear. When comparing SD vs HD, a higher resolution means that each pixel is smaller. (The pixel is the basic building block of a digital picture.)
The typical Standard Definition TV refresh rates are 25, 29.97, and 30 fps. The SD video quality is low with lower bitrates and file size. Compared to higher video resolutions, SD quality tends to be less defined and blurry. In slow internet connectivity, SD may come with an advantage. SD requires less bandwidth for streaming which means a slower internet speed. SD videos will stream smoothly with less buffering compared to higher-quality videos.
SD and HD both are video resolutions, which essentially means the number of pixels in a given video frame. The difference between the two is their respective video quality and the bandwidth consumption for streaming these videos. The number of pixels for the frame is different for SD and HD.
HD is much better than SD. HD or High definition has better video quality and has a pixel height of 1080 or 720p. SD or standard definition is lower quality and has a pixel height of 480p. If you want to watch a video in the better quality you should go for HD. If you have a poor internet connection and you want to stream your video online, then SD would be better. In the battle of SD vs HD, HD always trumps for video quality and SD for lower bandwidth consumption.
Pixels are the tiny blocks behind your screen that make up all the digital images you see, and the resolution refers to the size of these pixels. The larger the pixels, the fewer you can fit on screen, resulting in blocky, low-quality, or low-resolution, images. A higher resolution image has more pixel density, resulting in clearer, sharper video quality. The smaller the pixels, the more you can fit together to create a more detailed image.
The dimension of a video refers to how many pixels comprise an image length- and width-wise. For example, a low-quality image at 240 pixels (resolution) is usually 426 by 240 pixels (dimension). Changing the size of your dimensions can also alter how the resolution displays. For instance, increasing the dimensions spreads the pixels farther apart, reducing the quality of video playback. Uploading your video in the right dimension and resolution ensures that your video looks its best when watched.
For a high-quality image and small video file size, YouTube recommends uploading your videos in MP4 format with a 16:9 aspect ratio, as well as H.264 video codec and AAC audio codec (types of compression software that transfer image and sound). However YouTube also accepts any of the following video formats:
Resolution or aspect ratio refers to the number of pixels on display. The higher the resolution, the sharper the video quality. Inversely, lower the video resolution, and smaller file size. Which is why this is one of the most effective ways to compress a video. Generally speaking, HD videos are 1920 x 1080 pixels. On lowering the resolution, you may be compromising on quality.
Want to get a direct impression of "How a 480P video looks"? You can just open any typical YouTube video with a smartphone. The YouTube video that you play on a smartphone, is a 480P video.(YouTube is defaulting video quality to 480P on cellular networks.) Or, you can deploy yourself a 1080p+ display monitor. Pay a visit to YouTube, and adjust the quality of a video by [Settings] > [Quality] > 480p, 720p or 1080p.
480P: 480P(SD), known as the standard definition, stands for 640px*480px video/image resolution with an aspect ratio of 4:3.(Exclusively for YouTube videos, 480P is 854px*480px.) A 480P source is composed of 480 horizontal progressive scan lines/pixels in vertical direction and 640 vertical progressive scan lines/pixels in horizontal direction. Generally speaking, 480P contains 307,200 pixels to store video graphics information.
Further Reading: Technically speaking, all of these video quality/resolution are enhanced definition digital TV formats. "P" standing for progressive scan (non-interlaced) of horizontal lines. Or, you can check our hand-crafted illustration of video resolution below.
When opening videos from YouTube and other video-sharing sites, VLC tries to get the best quality of the video possible. The best quality that it fetches depends on a number of factors like the speed and bandwidth of your internet connection. The player will try to load the best video resolution that is feasible with the current connection. But what if you wanted to choose the quality/resolution of the online video that VLC loads from YouTube? There is an advanced option that allows us to select Full HD (1080p), HD (720p), Standard Definition (560p or 480p), Low Definition (360p), and Very Low Definition (240p). This video quality will be applied to the online media opened from video sharing sites like YouTube.
Audio: Some containers allow multiple audio tracks embedded in the video files. Hence the size of the video depends on no of tracks and bitrate of the audio as well. 192Kbps bitrate is considered good quality audio for stereo sound.
I've noticed that YouTube only offers three quality options for some videos when viewed on the video's page (240p, 360p, and 720p) even while the offered video elsewhere is significantly higher. One example of this is the following video: =DvY5irWC7kA (/u/aygoman of /r/Oman); when viewed in Chrome or when embedded in a page (such as through the RES addon), the video options are more verbose: 240p, 360p, 480p, 720p, 1080p, 2160p.
and double click on the entry showed to make it true and bold. Now html5 videos will show all resolutions. If this causes any problem,double click on the entry again to make it false. Make sure you are in html trial and flash is disabled on youtube.com
Original:I was using the Flash player on both my desktop (Windows 7) and my laptop (OSX 10.9.2); I found there was an update for Firefox from 29.0.1 to 30.0 so I completed it. After doing so, I did not appear to gain any quality options on my laptop, though on my desktop it appears that I now have access to all of the resolutions. Switching to the HTML5 viewer limited my streaming options to 360p on my laptop, and to 360p/720p on my desktop. It's worth noting, however, that the OSX binary does not appear to support H.264.
I'm still wondering why I can view all of the quality options on my laptop if the video is embedded, but I'm still limited to the aforementioned resolutions. I've attached screenshots showing the options present. 2ff7e9595c
