Input / Output Diagram
Dedicated software for the VC-30HD enables control of various parameters such as bit rate of MPEG-2 TS(HD: 50/35/8 Mbps, SD: 12/9/2 Mbps) and audio delay.
*1: USB output does not support embedded audio signal from IEEE1394 or control of audio volume.
*2: USB output supports bit rate up to 25Mbps.
*3: Mac does not have drivers to support HDV/DV/MPEG2-TS via USB.
*4: Audio and Timecode can be embedded in the IEEE1394 video output.
*5: Windows USB support for HDV format has become very limited and dated so should be avoided.
Built-in Audio Delay Setting
The VC-30HD has appropriate compensation built-in so audio and video are in sync from the USB or firewire ports with the delay setting at 0. However, depending on the total signal flow from all connected devices and/or the encoding/streaming software being used, audio may not always be in sync. The audio delay setting in the VC-30HD is there to compensate for whatever may be happening outside the unit. Set the delay as required by watching the final encoded stream. Use a clapper or a percussive device to clearly match the sound to the video image. The VC-30HD allows up to 30 frames of delay compensation (1 second) in increments of 0.1 frames (3.3msec) - enabling the perfect lip sync.
