HDMI to SDI converter options for on-camera use and steadicam monitoring in 2014

12 years old. Gear and prices may have changed since.

What the thread found

  • The Atomos converter offers a compact form factor with internal battery and external power options suitable for steadicam mounting.
  • The Blackmagic Hyperdeck Shuttle provides simultaneous SDI and HDMI outputs plus onboard ProRes recording capability but has a larger footprint than the Atomos.
  • The Teradek Bolt 300 includes both HDMI and SDI inputs and outputs but can only use one output at a time and generates significant heat during operation.
  • Dedicated cross-conversion boxes from manufacturers like AJA and Decimator cost around $695 and up, while one-way converters like the Atomos are priced lower.
  • The Atomos can supply dual SDI outputs simultaneously, allowing one feed to a wireless transmitter and another to a monitor.
  • Powering the Hyperdeck Shuttle from steadicam power using a modified AC adapter with spliced connectors provides an alternative to battery operation.
  • Recording capability on the Hyperdeck Shuttle has proven useful for creating dailies and reels during production.

Depends on

  • The Hyperdeck Shuttle's internal battery provides approximately 2 hours of operation and is considered unreliable for long shoots.
  • The Atomos requires a separate battery to carry and charge on set, which adds operational complexity.
  • The Teradek Bolt 300 runs very hot and may have durability concerns with extended use.
  • Hyperdeck Shuttle has mounting and power connector limitations compared to smaller converters.
  • No converter mentioned offers true pass-through functionality combining signal conversion with simultaneous transmission without signal loss.
