FS4 Frame Synchronizer/Converter v1.1
Single Channel Mode frame rate conversion within the same “family” of frame rates are
supported for HD/SD signals, and for up and down format conversion only to or from 4K/
UltraHD signals. These frame rate families are:
• 59.94/29.97/23.98
• 50/25
• 60/30/24
However, when the FS4’s input and output are both 4K or UltraHD, the frame rates must
be the same even within the same family. For example, if the FS4 receives UltraHD 59.94,
when it is configured for UltraHD output, that frame rate must also be 59.94.
Audio processing and routing in Single Channel Mode is similar to Four Channel Mode,

Video Processor(s)
Each Video Processor performs format conversion, frame synchronization, signal
processing, and keying operations. Conversion is done with very high quality scalers. De-
interlacing is performed with high quality motion-adaptive processing including
diagonal filters. The Processing Amplifier and Color Corrector supports video signal
adjustment with standard Proc Amp controls and RGB-style color correction.
