Let's assume that the used encoder reports a minimum bitrate of 3000 kBit/s and a maximum bitrate of 80000 kBit/s.Now we assume that you have entered 50% and 75% as the custom values. Than the encoder will use the following bitrates, if you choose "Custom" in the bitrate option:- Constant bitrate: 5500 kBit/s (3000 + (0,5 * 5000)) all the time- Variable bitrate (average): The encoder will use a bitrate between 3000 kBit/s and 8000 kBit/s, but in a specific timeperiod (normally 5 minutes) the average bitrate is 5500 kBit/s (3000 + (0,5 * 5000))- Variable bitrate (Peak): The encoder will use a bitrate between 3000 kBit/s and 6750 kBit/s (3000 + (0,75*5000), but still in a specific timeperiod the average bitrate is 5500 kBit/s (3000 + (0,5 * 5000))If you choose other options for the bitrate, than the encoder will use the values which I explained in the last post. The custom option should only give the users the possibility to use a own value. The Peak value defines as you can see in the example the maximum bitrate that the encoder will use in the desired mode.Unfortunately an encoder has the possibility to support different ranges for the different encoding modes. This means that for Constant bitrate the range could be 3000-8000 kBit/s like in the example, but for the two variable bitrate modes the range is 5000-10000 kBit/s.Generally if you want the best quality you should just set the bitrate to "High" as this is identical to 100% in the custom values. As described above the maximum bitrate can be different, so you have to try unfortunately.I know that this isn't the best solution, but at the moment we don't know which encoder will be used when the recording starts. The reason is that the encoder is not stored in our configuration file. For HW-encoding cards normally TvServer will use always the same encoder, but for SW-encoding cards the encoder can change everytime as it depends on the installed encoders.MisterD</blockquote>
