SurCode for Dolby E Encoder

page 5

The imported metadata will immediately appear in SurCode, both on the Main tab and on the Pro-

gram tabs.

2.5 Frame Offset

SurCode for Dolby E Encoder allows for a time shift of the audio relative to the video. This can be

very useful with projects that involve encoding or decoding during tape transfers because these

operations often contribute one frame of shift between the audio and video.

SurCode has a pull-down menu to select no offset, or one or two frames of offset, either advanced

or delayed (see Figure 2-6). The plus (i.e. positive number) means the audio is being advanced

relative to the video.

Figure 2-6

The frame offset is recorded into the BWF header of the .wav file in the Coding History “T” field,

like this: “T=FrameOffset 2;”

2.6 Timecode

2.6.1 Start time

Start Time is a metadata value that gets saved into the encoded Dolby E file. It can be used during

decoding to, for instance, position the audio relative to playback of a video file. The Start Time

can be typed into the text box (see Figure 2-7).
