Keep this setting at the default value of 0, unless you are troubleshooting a problem with how devices play back
the end of your video asset. If you know that player devices are hanging on the final segment of your video
because the length of your final segment is too short, use this setting to specify a minimum final segment length,
in seconds. Choose a value that is greater than or equal to 1 and less than your segment length. When you specify
a value for this setting, the encoder will combine any final segment that is shorter than the length that you
specify with the previous segment. For example, your segment length is 3 seconds and your final segment is .5
seconds without a minimum final segment length; when you set the minimum final segment length to 1, your final
segment is 3.5 seconds.
