In the operation theatre

Filming a live surgical or medical procedure during a live surgery meeting demands an experienced crew and a specialised set-up.

We have been performing live surgery since 1992 during our medical training.

Live surgery is an educational tool to show to an expert audience a new surgical technique or approach, diagnostic procedure, tools, decisions, ...

Our purpose is to make sure that your public sees what needs to be seen, in the highest possible quality and that a fruitful discussion can be established between the operating doctor or surgeon and the public or moderator.

For this multiple cameras are installed in the OR to cover all aspects and stages of the procedure, from initial preparation to final closure. Our remote-controlled ‘boom’ cameras allow us to ‘fly’ over the operating field and capture high-resolution, close-up images of all steps. The nature of the procedure determines whether we work in 2D-HD, 3D-HD or UltraHD(4K).

We connect all relevant medical imaging devices, such as microscopes, echo, fluoroscopy, roadmap and hemodynamics, using high-end scan-converters to upgrade their native resolutions to HDTV (typically 1920x1080, 16:9) or UltraHD.

All the video feeds are transferred to the live mixing desk, which is installed in the vicinity of the OR. The operators’ commentaries are captured using wireless microphones, and patient history slides and graphics/statistics can be inserted into the live transmission. Then, video and audio sources are mixed, picture-in-pictures are created, titles and animations are overlaid and the final video-feed is transmitted. Of course, both the ‘live’ audio signals and the extensive internal communication between the camera operators, mixing desk and conference venue technical staff are handled here too.

You can read more about our work in a ‘medical AV context’ in our guide to the Do's and Don’ts of live surgery transmission. This whitepaper offers insights into AV production in an operative environment, gained through our extensive experience from the past two decades.

Transmission to the congress

We choose the most appropriate method for transmitting images and sound from the OR to the congress venue, depending on distances involved and technical requirements. For instance, transcontinental transmissions are sent via (single or dual feed) satellite links. Alternatively, radiofrequency transmission or high-speed point-to-point Wi-Fi may be used to carry images and sound to the conference venue. We may also opt for videoconference or IP transmission. However, it can be difficult to reconcile our desire for optimal image quality with the often intermittent and patchy transmission that these ‘low-bandwidth’ transmissions are able to offer.

To read more about, see our White Paper on transmission technology over the years.

Medical Video Production

We proceed as we would for any live surgery project. During filming, we anticipate and focus on the important steps of the procedure. We record all medical sources, and audio of course. Plus, we create the background and other visuals based on the graphics and organisation identity.

The recording results in a full-length version of the procedure, with all steps included. Recordings are made using HD-TV broadcast standards such as HDXDCAM or the Apple PRORES HQ H.264 CODEC, or H.265 (UltraHD/4K). Immediately after the procedure, an initial rough cut can be made onsite by our director/editor, alongside the doctors or sponsor representatives.

Further editing is carried out in our studios. Multiple versions of the recorded case at various lengths can be produced, with additional images/animations and graphics inserted. The videos can be exported in any format or resolution, for DVD/USB-stick-production, web publishing or insertion into PowerPoint/Keynote presentations.
