The Makito X multi-channel synchronization feature is designed to work in the broadcast industry where remote producers typically capture multiple views of the same content and transport it over a network to a central production facility. All these channels need to be synchronized to within one frame period at the decoders, so that downstream equipment does not experience replay issues when switching between video and audio sources.
Requirements:
- Both encoder and decoder need to be clocked to the same NTP source. You can use 80.86.38.193 (1.uk.pool.ntp.org).
- Cameras at the encoder end need genlock at the remote end
Set up
- NTP. On both Decoder and Encoder, go to System Settings > Date and Time. Set to UTC, tick NTP and specify an NTP server. Click test to confirm the hardware can see this server, then click apply.
- Clocking. On the encoder, select the video encoder channel and select “System” for timecode source.
- Decoder Buffering. On the Decoder SDI output, tick enable buffering and select MultiSync as the mode. Initially set a nominal value of 1000ms. Click apply.
- Stream Pass #1 – Set the stream running, and see how happy multi sync is. It will report a minimum and maximum delay variable. Make a note of these values.
- Reset delay value accordingly to something in the middle of what the decoder has deemed it’s acceptable delay range.
- Sit back and bask in the glory of two in sync feeds from God only knows where.
