Therefore, there may be slight difference with the input signal if there is section with large deviation in the horizontal direction in the corresponding input

signal even if the 4K signal is selected with ME2 and output as 4K signal without processing.

r 4K resolution processing and 2K resolution processing

The "ME2 processing unit" and the "combination processing unit for the ME2 output and DSK" of the unit is processing the image in 4K resolution

(3840×2160).

Image is processed in other image processing unit (key processing unit of ME1 and DSK, video memory, AUX, MultiView. etc.) in 2K resolution

(1920×1080) to reduce the image processing load.

Therefore, there will be change in the resolution feeling when the signal that has passed through the image processing unit of 2K resolution is selected

even when the input 4K signal is selected and output as 4K without any change.

As an example, the resolution is reduced compared with the input signal when input 4K signal is selected in ME1 or the AUX bus, and output as the 4K

signal.

The image is recorded in 2K resolution in the video memory (Still, Clip). The image size that can be read from the memory card will also be 2K

resolution (1920×1080).

r Image processing delay

To perform the above processes (4K resolution process and 2K resolution process), both the 4K signal and the 2K signal are output for each input signal

from the FS unit.

There is processing delay of one frame (1 F) in the FS unit. Therefore, the minimum delay when the unit is operating in the 4K mode will be 1 F.

The signal is output with delay of 1 F when the input signal is selected with ME2 and output directly as 4K signal or when the input signal is selected

with ME1 and output directly as 2K signal.

Delay of another 1 F will be added when the signal that has passed through the image processing unit in the 2K resolution is output as the 4K signal

because it will pass through the processing to enlarge to the 4K resolution.

Similarly, delay of 1 F is also added to the ME1 output signal selected as a re-entry source with ME2. To eliminate the delay difference when switching

between the re-entry source and the input source, the delay for 4K signal from the FS unit can be changed to 2 F.

f <SYS> button → [SYSTEM] → [Video] tab → [Latency] column → [4K FS] item

- [Minimum]: Outputs with minimum delay (1F).

- [+1F]: Outputs only the 4K signal with 2 F delay.

However, another 2 F delay is added to the signal passing through the DVE or MV of ME1.
