Bitrate is the speed which a video or audio is transmitted, measured in bits per seconds. Typically:
– Video played on smart phones has a bit rate measured in kilobits per second (kbps).
– High-quality video found on the web has a bit rate around two megabits per second (mbps).
– Standard-definition DVD video is usually about 6 mbps.
– HD Blu-ray video is about 20 mbps.

How bitrate influences video/audio quality?

The higher the bit rate of a video, the more data gets transferred at a time. Therefore, higher bitrate usually means high quality video. However, video with very high bit rate will also strain the capacity of slower Internet connections and many mobile devices. This can result in buffering and interrupted streaming. Therefore, to save more space for your device and also achieve a smooth video streaming or transferring process, you will need a bitrate converter program to change the bitrate of different video and audio from high to low.

Best Bitrate Converter to Change/Convert Video/Audio Bitrate

Although there are many programs on the market can assist you to complete the job, however, you may find that some program are only available on Windows platform, others are cross-platform, but has poor media importing capability. Fortunately, here comes Pavtube Video Converter Ultimate, which is available on both Windows and Mac (get Mac version) platform. The program has full support all media types including commercial Blu-ray/DVD disc and digital video and audio file formats in virtually any file formats. You can lower the bit rate value for the output video and audio in the program’s “Profile settings window” to get a small file size video for space conservation, in addition, you can also change other profile settings such as video resolution, frame rate, audio sample rate, aspect ratio, etc.

Tips: To produce a high quality video lower bitrate video, make sure to set your video bit rate to let it match with your video frame rate, resolution, aspect ratio, etc. For example, to get the best uploading settings, you should set your video/audio bit rate and frame rate as the tablets below:

SDR uploads

Resolution	Video Bitrate, Standard Frame Rate (24, 25, 30)	Video Bitrate, High Frame Rate (48, 50, 60)
2160p (4k)	35-45 Mbps	53-68 Mbps
1440p (2k)	16Mbps	24Mbps
1080p	8Mbps	12Mbps
720p	5Mbps	7.5Mbps

HDR uploads

Resolution	Video Bitrate, Standard Frame Rate (24, 25, 30)	Video Bitrate, High Frame Rate (48, 50, 60)
2160p (4k)	44-56 Mbps	66-85 Mbps
1440p (2k)	20 Mbps	30 Mbps
1080p	10 Mbps	15 Mbps
720p	6.5 Mbps	9.5 Mbps

Step 3: Adjust output video/audio bitrate.

Click “Settings” on the main interface to open the “Profile Settings” window, here, you can flexibly lower output video or audio bit rate, make sure to tweak other profile parameters settings such as video resolution, frame rate, aspect ratio, audio bitrate, sample rate, etc to let them match with your bitrate value.

Step 4: Begin the conversion process.

After all setting is completed, hit the “Convert” button at the right bottom of the main interface to begin the output video/audio bitrate conversion process.

When the conversion is finished, click “Open Output Folder” icon on the main interface to open the folder with generated files. you can then get a lower bitrate video with small file size but high quality video for viewing on smartphones, tablets, TVs, etc.
