Specifications

Mbps: Fill in a manual mux rate in Mbps. Decimal values are allowed (e.g. 19.2 Mbps).

Omit Null Packets: Compliant transport streams are always constant bit rate files. Empty space in the file is

full with Null packets to insure that the bit rate remains constant. This can cause very large files to be created if

the multiplex rate is significantly higher than that required by the audio and video streams. When this option

is checked, Null packets will be not be output. This option is safe to use with many software players. However,

for fully compliant streams which may be broadcast, please leave this option checked.

Note: If you create a stream without Null packets and later want to add them back in, simply check this option

and run Tools>QuickStream Fix on the file.

Abort After N Buffer Underflows: When the mux rate is too low, underflows will result. An underflow

occurs when the audio or video data is delayed. For example, if the video bit rate is an actual 10 Mbps and the

Mux rate is 5 Mbps, the transport stream will not be able to transmit the video data quickly enough and

underflows will result. Use this parameter to specify how many underflows will be tolerated before output is

aborted. A small number of underflows may be acceptable if your output is intended to be played on a

software player or the output isn't critical.

Note: Underflows do NOT cause any loss of data in the output file. If you output a file with underflows, you

can come back later and re-multiplex using Tools>QuickStream Fix at a higher mux rate to remove the underflows.
