What the thread found

• FireWire connections on older DV and HDV recorders expect a native DV signal over the FireWire port, not standard video signals like SDI or HDMI
• Converting SDI or HDMI directly to a true DV signal suitable for FireWire input is not straightforward and no simple cable solution exists
• One potential workaround involves using a miniDV camera that accepts external video input and then outputting its DV signal via FireWire to a compatible recorder
• Using a separate hardware recorder with native HDMI or SDI inputs may be more practical than attempting complex signal conversions for steadicam applications
• Some recorders support a rec trigger function that allows the camera to automatically start recording on the external recorder simultaneously, though compatibility varies by camera model

Depends on

• The FireWire bandwidth may be insufficient for full-quality SDI signals
• The rec trigger compatibility only works with specific camera models such as Red and Sony cameras, not with Alexa or Canon C300 cameras
• Solutions discussed assume older DV/HDV format recorders; modern alternatives with direct digital inputs are recommended
• This discussion does not address whether custom hardware conversion solutions exist beyond commercially available products
