New Phantom Flex4K-GS adds Global Shutter to the King of Slow-Mo

Vision Research, a brand name synonymous with high-end pro super-slow motion cameras, recently announced the newest addition to their Phantom Flex line-up of cameras – the Phantom Flex4K-GS. The GS in the name stands for “Global Shutter”, which eliminates imaging artifacts associated with motion skew; the Flex4K-GS features a custom sensor capable of recording 1,000 fps at True 4K DCI (4096 x 2160) resolution.

Much like the rest of the Phantom Flex lineup, the Flex4K-GS is built like a tank; it has isolated electronics and thermal design that allow for operation in environments within the temperature range of -20°C to 50°C, all the while maintaining a stable image.

The Phantom Flex4K-GS is available with either 64GB or 128GB of RAM and works with CineMag IV non-volatile memory magazines for the fastest data transfer. Uncompressed raw or compressed video in Apple ProRes 422 HQ is also possible.

When working with ProRes, a 2TB CineMag-IV will hold several hours’ worth of footage. The Flex4K-GS is also fully compatible with Phantom PCC software and can be easily synchronized and used in combination with other Phantom camera models.

The new Phantom camera is expected to be a “strictly rental item” for 99% of productions given its specialist nature and price tag of over $100K to match. For the rest of us mortals, we’ll do with a Sony FS5 and a Shogun Inferno/Odyssey7Q+ combo for super slow-mo up to 240fps in 2K.
