![]() ![]() I'll discuss a possible reason for this, later in this message. So, I set it to 720p, at just 6 Mbps and it looked significantly sharper. The result is a much higher quality file.I have experimented with all sorts of settings, but never could get the resolution I thought there should be, with the 1080p video in Fine mode at 12 Mbps. The codec guesses which parts could benefit from more bits per second, and which can use less. ![]() As it's name implies, the bitrate is varied throughout the file. Variable Bit Rate (VBR) is an MP3 encoding method that's used when file size is not an issue. If your audio has moments of silence, it is captured and encoded at that rate, as are areas of very diverse frequencies (that might sound better if encoded to a higher bitrate). All that means is no matter what, there will always be 192 kbps written into the bitstream. Constant Bit Rate (CBR) encoding maintains the same bitrate throughout an encoded file. Of course, the file size of the end product corresponds directly with the bitrate.ġ92 kbps is an example of a constant bitrate ( CBR) mode. If the bitrate is high, the codec will be applied with leniency, and the end result will sound better. If the bitrate is low, the irrelevancy and redundancy criteria will be measured harshly, and more subtlety will be stripped out, resulting in a lower-quality product. The CODEC takes the bitrate into consideration as it writes each frame to the bitstream. Obviously, the higher the number, the more accurately the wave form is approximated.įor example, the current de facto standard is to encode MP3 at 192 kbps, or 192,000 bits per second. Bitrate is defined as the number of data points used to approximate the true wave form.
