Example 1:
VideoStartTime=17:43:13.84
Audio Start Time = 17:45:35.41
In the above diagram, the start and end times of the video and audio files are different.
NOTE: The difference in start time is exaggerated to illustrate this point. In practice, the
difference will be much smaller.
To create the correct number of video frames and a .WVA file of the correct length you must
specify the correct Start and Finish times within the gcode command line.
For this example a Start time of 17:45:35.50 (after both the audio and video files have
started) and a Finish time of 17:49:11.00 (before either file finishes) would be appropriate.
This results in video and audio files of the same length being created. These files can be
used with third-party video editing software to produce a correctly lip-synced file.
You will need two separate commands, the first to generate the video file and the second to
generate the audio file:
./gcode ‑t ‑o /home/matrix_rec/Targa ‑s 17:45:35.50
‑f 17:49:11.00 ‑i /home/matrix_rec/Storage/SAC_Test/
