Camera HDMI: output format, converters and operator monitor

Camera dropouts: check the equipment inside the rack too

An SDI label on a rack panel does not establish that the switcher has an SDI input. Trace the wiring and identify the complete chain before attributing a problem to scaling, reclocking or cable length.

Before testing, map camera → converter → cable run → panel → internal converter → switcher. Physically check what enters and leaves each unit, and record its full model. Compare a short connection with the event path while keeping the format unchanged. If the dropout returns when you add a stage, record that segment before changing anything else.

A7 III: check HDMI Resolution separately from the recording format

On the Sony A7 III (ILCE-7M3), the HDMI Settings: HDMI Resolution menu (guide 4-732-947-18(2), p. 334) offers Auto, 2160p/1080p, 1080p and 1080i. Sony says to choose an option compatible with the destination if Auto does not display the picture correctly. Go to MENU > Setup > HDMI Settings > HDMI Resolution and record the setting before changing it. These names apply to the A7 III; they are not an A7 IV setup procedure.

For the comparison, agree on a signal supported by every device in the path and check which format the receiver detects. Record resolution, exact frame rate and scan type separately. If you test 1080i, save a sample with motion and listen to program audio. Restoring a picture does not establish that the motion or delivery format meets your needs.

The manual allows that output selection, but it does not diagnose the rack fault or make the setting a universal preference. The fields and deinterlacing guide covers the editing file; this check follows the live signal.

HXR-NX100: distinguish REC FORMAT, HDMI output and on-screen information

The HXR-NX100 Operating Guide, 4-580-997-11(1), pp. 36, 66–67 and 81, separates REC FORMAT from VIDEO OUT > HDMI. It describes output conversion for 25p recordings on the 50i variant and 24p/30p on the 60i variant. The manual covers both variants and warns that the camera cannot switch between them. Record which you have; do not infer the received frame rate from the file name alone.

To keep camera information on its own screen, check DISPLAY SET > DISPLAY OUTPUT > LCD PANEL. Page 88 distinguishes ALL OUTPUT, which also sends information, zebra, peaking and face-detection frames over HDMI/VIDEO OUT. Overlays may help the operator but be unsuitable for program. Check both views while adjusting focus and opening the controls used during the event.

During the test, save the initial setting, compare a card recording with a capture of the live path, and label both samples. If the file is correct but the switcher signal fails, follow the output and its stages. If only the file fails, check the recording path. This is a proposed test; no NX100 operation or HDMI measurement is reported here.

A monitor with loop-through output can share HDMI with the switcher

To add an operator monitor, compare three options: a monitor with HDMI loop-through, an HDMI distribution amplifier, or a converter with an additional SDI output. Choose based on compatible inputs, outputs and formats, and check both destinations.

The official product information for the 5-inch F5, under 4K HDMI Input & Loop Output, documents HDMI input and loop-through output. This is the original F5, not the Pro or V2; its product information does not identify firmware. You can prepare the path camera → monitor HDMI IN → HDMI OUT → converter → switcher. Seeing a picture on the monitor still leaves the downstream chain to be checked.

Test that path with the actual equipment before using it for a talk or concert. Enable the monitor's focus and exposure aids and check what reaches program. Off-air, test what happens when the monitor powers down or restarts and when power returns. If it interrupts the switcher, record that and prepare another distribution route. The cited product information does not establish loop-through behavior without power or whether overlays reach that output; the F5 manual still needs checking.

NX100: check accessory power requirements before using USB

Before using the NX100 Multi/Micro USB port to power a 5 V accessory, confirm that Sony specifies that use for the exact model. The Sony manual sections USB CONNECT (p. 91) and connectors (p. 114) do not provide a 5 V output specification or available current for that use there. Using the port as a power source requires an applicable Sony specification for the intended accessory.

Identify the exact accessory and prepare the power source specified by its manufacturer. For the original F5, Specifications > General, the product information lists a DC 7–24 V input and power consumption of ≤8 W. That range applies to the monitor, not to the NX100 USB port or every Micro Converter. Similar connectors do not make power inputs and outputs interchangeable.

Record the voltage, current or power, polarity, connector and required runtime for each device in the worksheet. Check startup and recovery off-air using the intended power source. Confirm the converter model and its manual before connecting; do not test an unspecified supply by plugging it in.

Document a comparison that lets you restore the initial setup

Use motion, speech and a detailed shot representative of the event. Start with a documented short path and repeat the same shot as you add the monitor, converters and cable run. Change only one variable per comparison: format, stage or power. Record observed dropouts and when they occur, even if one setup restores a picture.

The HDMI and operator monitoring worksheet is blank for you to complete during testing. Keep the initial settings and samples. Recheck the file, program and remote reception if you will be streaming; a working local monitor does not verify the destination of the live stream.

For camera positions, lenses and shot assignments, see the event camera guide. Planning the camera and streaming service also requires setup, rehearsal and operating schedules, as well as the signal diagram.
