Frame Sync and Format Conversion

The switcher has multiple input frame synchronizer / format converter (FSFC) and input de-interlacers that can be used to convert video input signals to the format that the switcher is operating in, as well as correct mistimed, or drifting, video input signal. The frame synchronizers cannot completely correct badly formatted video, mistimed switches, signal drops, or similar issues.

Each FSFC channel maintains a separate setting for different video formats. This lets you change between video formats without losing FSFC channel configurations.

The switcher has 6 FSFC channels that can be assigned to any input, and 4 additional frame syncs from the Media​-Store (MSFS). Each Media​-Store channel can be converted to a frame sync and assigned to an input, this removes the Media​-Store functionality.

Keep the following in mind when working with Frame Synchronizers and Format Converters:

  • The Media​-Store Frame Syncs (MSFS) do no support format conversion. If you need format conversion, you must use a standard FSFC.
  • If the switcher is operating in 1080p 59.94, you can only use a maximum of 7 frame synchronizers to sync 1080p 59.94 video inputs. This can be up to 3 FSFCs and 4 MSFSs or 6 FSFCs and 1 MSFS. Format conversion is not restricted.
  • If a video format not compatible with the currently defined conversion is used, the video image is frozen with the last successfully processed image frame.
  • FSFCs create a one-frame delay in the video output of the switcher for the video signal being converted.
  • FSFCs strip embedded audio data from the video signal. Ensure that no FSFC channels are assigned to any input or bus you are using with external audio mode.
  • The FSFCs used in the switcher conform to the SMPTE ST 125:2013 standard. Some older equipment may not fully conform to the current standards and can send out-of-spec video to the switcher which can have unexpected results. Ensure that video coming into the switcher conforms to current standards, especially with regard to 480i video signals with variable blanking sizes.
