 A video’s bitrate is a key piece of information in determining the quality of said video. Even if two videos have the same resolution, a lower bitrate is going to result in less detail and clarity. Here’s how to see the bitrate of any video you’re playing in real time with VLC. 

  視頻的比特率是肯定所述視頻質量的關鍵信息。 即便兩個視頻具備相同的分辨率，較低的比特率也會致使細節和清晰度下降。 這是經過VLC實時查看正在播放的任何視頻的比特率的方法。  

 VLC is a powerful, cross-platform app that can play virtually any video file and has a ton of hidden features. One handy little tool lets you see a video’s bitrate in real time. Higher bitrates mean more detail, but it also requires more processing power and bandwidth. Lower bitrates may be easier to stream or to play back on older hardware, but you’ll see a decrease in picture quality. 

  VLC是一款功能強大的跨平臺應用程序，幾乎能夠播聽任何視頻文件，而且具備大量隱藏功能 。 一個方便的小工具可以讓您實時查看視頻的比特率。 更高的比特率意味着更多細節，但同時也須要更多處理能力和帶寬。 較低的比特率可能更易於流傳輸或在較舊的硬件上播放，可是您會發現圖像質量降低。  

 NOTE: Most videos use a variable bitrate that can change from moment to moment. VLC lets you see which scenes use a higher bitrate to identify areas that may cause playback problems or crush the quality of your video. If you just want to see a video’s overall bitrate, check out our guide on how to do that in Windows or macOS here. 

  注意：大多數視頻使用可變比特率，該比特率可能會隨時變化。 VLC使您能夠查看哪些場景使用更高的比特率來識別可能致使播放問題或視頻質量降低的區域。 若是您只想查看視頻的總體比特率，請在此處查看有關如何在Windows或macOS中執行該操做的指南。  

 To find your video’s bitrate information, open up a video in VLC and click on the Tools menu and select Media Information. 

  要查找視頻的比特率信息，請在VLC中打開視頻，而後單擊「工具」菜單上的「媒體信息」。  

 

  

 

 In the window that appears, click the Statistics tab. 

  在出現的窗口中，單擊「統計信息」選項卡。  

 

  

 

 On this screen, you’ll see a chart under Input/Read. This displays a live view of the bitrate of your video as you watch it. Play the video for a few seconds to get enough data for this chart to fill in. The entry next to 「Content bitrate」 will most accurately represent what bitrate a video is using at the current time in the video. 

  在此屏幕上，您將在輸入/讀取下看到一個圖表。 觀看視頻時，它將實時顯示視頻的比特率。 播放視頻幾秒鐘，以獲取足夠的數據以填寫此圖表。「內容比特率」旁邊的條目將最準確地表明視頻當前在視頻中使用的比特率。  

 

  

 

 You’ll notice as you play the video that the bitrate will raise and lower depending on what’s on the screen and how much movement there is. The peak bitrates will give you an idea of how much bandwidth you’ll need if you want to stream the video over the internet without any degradation in quality or converting the video. 

  在播放視頻時，您會注意到比特率會根據屏幕上的內容和移動的多少而升高和下降。 若是您想經過互聯網流式傳輸視頻而又不下降質量或轉換視頻，則峯值比特率將使您瞭解須要多少帶寬。
