The Phantom Flex 4k is known to be the ultimate tool for slow-motion capture: it shoots 938 fps in 4K and 1,984fps at 2K, producing extremely mesmerizing footage (seriously, look at some clips… it’s droolworthy).The camera comes with a hefty price tag—$60k-$150k—so it has always been more rental-oriented. And it’s rare: it’s rumored that there are only a handful of these cameras in the New York area (two of which are on KitSplit!).

Rent the Phantom Flex on KitSplit here.

Opportunities to see, learn about, and play with the Phantom Flex 4k are unusual. So KitSplit was very excited to host a workshop on the camera with Phantom operator and filmmaker Tore Knos this weekend.

In the workshop, Tore covered a variety of topics related to the camera, including the fundamentals of high-speed photography, how to set-up and operate the camera, and the unique production and post-production workflows associated with Vision Research’s Phantom Flex4K. You can watch the full workshop below:

Some key takeaways about the Phantom Flex 4k:

  • Although the Phantom Flex 4k seems intimidating, Tore told the room, “any one of you can operate a Phantom Flex 4k. In terms of the menu options and settings, it’s actually less complicated than some cameras at a lower price point such as RED cameras.”   
  • The buttons on the camera are not configurable, but they are intuitive! Trigger, capture, playback and save buttons are on both sides of the camera. You can also trigger with a handheld remote control.
  • You “trigger” the camera to record and save footage. When you press the trigger, it saves the 5 seconds previous to triggering. Therefore, you trigger right after the event you want to record has taken place.
  • The Phantom Flex 4K is available with up to 64 GB of internal RAM. Once the camera is triggered, the files can be offloaded to a CineMag, available up to 2TB (which can cost up to a whopping $25,000!)
  • The camera can be set to write either raw or compressed files. There are benefits to either option: of course, raw files are uncompressed and maintain the most information for processing. They are compatible with several post processing and color grading systems, or can be converted to a variety of formats using the software provided with the camera. If you decide to save compressed files, it’s a slower in-camera workflow, and can cause delays on set. However, this increases record time and decreases file size, and simplifies the process out of the camera.
  • Because the file sizes are so large, the camera does not automatically save what it films. You have to “opt in,” or save every clip you want to retain.
  • Even though the video files are so large, they can be edited on a MacBook Pro with Adobe Premiere (evidence in video, above!).
