The other highlighted description in Figure 3 is Encoding Settings, and here MediaInfo, particularly in HTML view, becomes a gold mine, especially when viewing most files encoded with FFmpeg. Most codecs get more efficient at higher resolutions, and, of course, HEVC is more efficient than H.264, which is why a bits-per-pixel value of 0.039 for an 8K HEVC encoded video is more than adequate. If you’ve to compare two videos with different resolutions and bitrates, the bits/pixel value gives you a common data point to compare how much compression was applied to the file. If you watch a very high-quality 1080p video and the bits/pixel value is 0.400, it’s a good guess that the data rate is much higher than necessary. So, if you’re watching a 1080p H.264-encoded video that looks terrible, and the bits/pixel value is 0.05, the problem is very likely that the data rate was too low. As a very general rule of thumb, a bits/pixel value of around 0.1 is sufficient to produce good quality in a 1080p H.264-encoded video. Figure 3 shows an 8K file which is why the bits/pixel value is a relatively low 0.039. MediaInfo in Tree view.īits/pixel is another critical data point, which as the title suggests, shows the amount of data allocated to each pixel in the video. I’ve just started working with HDR files where information like color primaries and mastering display color primaries are absolutely essential to understanding critical parameters of the file you’re about to encode and the files that you’ve produced. Most of the information is self-explanatory, like Format (codec), profile, duration, bit rate, width, height, frame rate, and bit depth. There are three major sections, General, which shows container format, duration, file size, overall bitrate, and other data Video, which details video characteristics, and Audio, which does the same for audio. The MediaInfo Tooltip.įigure 3 shows the data presented by MediaInfo. You can open multiple instances of MediaInfo, and once an instance is open, you can change files by dragging a different file onto the interface.īack in the preferences window, it’s also nice to be able to hover your pointer over a media file in Explorer and load the Explorer Tooltip, which identifies the container format, data rate, resolution, frame rate, codec, and codec-related information like profile (Figure 2). Most relevant is to enable the Explorer extension, which allows you to right-click a media file and open the file within MediaInfo. The three checked boxes on the right are checked by default. I prefer the Tree view shown in Figure 3 and use the HTML view shown in Figure 4 frequently to view encoding details-more on that below. Here you choose your default view out of the about 15 different views for the data. Once you install MediaInfo on Windows, you should explore the preferences that you access from the Options menu (Figure 1). It’s available for download here, and there are versions for Windows, Mac, iOS, Android, Debian, Ubuntu, Linux Mint, and many other operating systems. MediaInfo is a video analysis tool that displays the most significant data points regarding a video file, including resolution, data rate, codec, bit depth, frame rate, duration, etc. Here are two free Windows tools that I couldn’t live without. Streaming producers need tools to explore different encoding options and verify their work.
