This flow element will convert audio to a the options selected.

Convert

  • All: All tracks will be converted
  • Matching: The tracks matching the fields will be converted

Matching

You can specific which tracks based on the following

PropertyDescription
ChanenlsCan use Math Operations or specific how many channels exactly
CodecCan use String Operations
LanguageWill compare the language specified using the Language Helper which compares languages based on their names and ISO codes, so 'en' will match English and eng
TitleCan use String Operations

If no tracks match then no tracks will be converted

Codec

The codec to use to encode the audio

Channels

The number of channels this new audio track will be. If you specify more channels than the source, FFmpeg will automatically up mix it. If you specify fewer channels than the source, FFmpeg will automatically down mix it.

Automatic

This will not pass the channels to FFmpeg and leave it up to FFmpeg to determine the channels from the source track.

Same As Source

This will pass the same number of channels as the source track to FFmpeg for the converted track.

Bitrate

Bitrate of the audio track

Automatic

This leaves the bitrate up to FFmpeg to decide and is the default option.

Same as source

This will use the same bitrate as the original audio.

Bitrate Per Channel

If the bitrate specified should be per channel.

For example if checked and bitrate is set to 100K, and there are 6 channels, then the audio bitrate will be 600K.

tip

If the audio is already in the choosen Codec and Channels is set to Same as source and Bitrate is set to Automatic or Same as source then the audio will not be re-encoded and will just be copied


Outputs

  1. Audio tracks matched the parameters and will be converted
  2. Audio tracks did not match and no conversion will occur
