ARRI ALEXA Hits 120FPS with Software Update

I'm a bit uncomfortable with how camera-focused this site has been over the past couple of weeks, but there's so much going on it's hard to keep up! That's one reason I'm hiring more writers (I'll be closing down the application in a day or two). Here's some more camera news, though: ARRI has released Software Update 5 for their ALEXA, which brings 120 FPS recording to the camera along with several other new features (list below). To help ARRI demonstrate what 120fps looks like, I decided to grow my hair out and take up juggling. Check out my favorite vest:

To shoot at 120FPS on the ALEXA, which uses 4:2:2 HQ ProRes, you must use the latest/fastest Sony SxS Pro 64 GB cards, which run two grand apiece. And here I was thinking that the 64GB REDMAG SSD was expensive at $950! Sony's SxS media is more than twice as expensive per gigabyte. Then again, by my calculations 4:2:2 HQ ProRes takes up less than half the space of REDCODE 6:1 (SCARLET's default compression setting at 4K/24p), so in that sense I suppose it evens out.

More new features in SUP 5.0 below.

  • 60 fps ARRIRAW over 3G Dual Link
  • 60 fps HD-SDI 4:4:4 over 3G Dual Link
  • 60 fps ProRes 4444 when using SxS PRO 64 GB cards
  • Horizontal Image Mirroring (3D)
  • ARRI Look Files for playback of QuickTime/ProRes Log C files
  • Reel & clip number on MON OUT
  • Secure camera display dimming
  • Active look indication
  • Dual record error handling
  • Open Camera Access (OCA) initiative
  • Support for Lens Data Display for Focus Puller (ALEXA Plus only)

I love high-speed. Here's one I just found that cranks RED Epic to 300fps:

Ultra-high speed to me has far more creative applications than 3D, and far more universal appeal. It can make the mundane look spectacular. This video in particular introduced me to that:

I can't wait until the technology gets to a consumer price-point.

Yes, nice vest and you went to Munich, only for shooting test footage, kudos to you! ;)

I'd buy the ARRI if it includes the vest.

Was about to order Alexa but when I saw the vest, I decided to buy 5D instead.

Wow. This footage is phenomenal. It's amazing to see the detail in the background as well, especially considering how dark it was outside.
