Please join Tessive at NAB this year. We will be in booth C9649 in the central hall. We will be demonstrating the Time Filter live, and showing off its newest capabilities.
Also, Tessive has been invited to talk in the HPA Post Pit at NAB. Join us for our presentation on Monday, April 16th, at 2:20 in the NAB Post Pit.
Andy Shipsides with AbelCine has written a great article about 24 fps judder: it's causes and how to deal with it. The article appears in the February 2012 edition of HDVideoPro, and he sums up the issue very well. He also mentions the Time Filter in the article as a way to deal with the issue. Check out this excellent article if you haven't seen it on page 26.
Andy contacted me last year as he was researching the topic, and I was very impressed with his technical and practical grasp of the situation. Great article!
In the latest firmware update we've rolled out to the Time Filter, we've added an often requested feature: variable neutral density. Here's how it works: if the system is shuttering (running the Tessive shutter or a 180 degree global shutter) then the system operates at 2.5, 3, or 4 stops. When in this shuttering mode, the camera is set to a 360 degree shutter, so you gain a stop back compared with running at a 180 degree shutter, so these are effectively 1.5, 2, and 3 stops. We always display the effective total stop loss of just the Time Filter on the main display, regardless of what the camera shutter is set to, so you can compute exposure as though it's a neutral density filter.
If you don't want to use the Time Filter to do any shuttering, you can turn shuttering off and just use it as a steady, unchanging variable ND filter. In this mode, it can provide ND from 2 to 7 stops in half-stop increments.
The Time Filter cuts light wavelengths down to 750 nm, which means it cuts the infrared that sometimes causes brownish casts to dark fabric when imaged with a CMOS sensor. Therefore, it is a variable IRND.
Tessive will be at the Createasphere Tech Expo in Burbank, November 2 and 3, at booth 606. Come join us. We will be demonstrating the Time Filter and answering your questions about our system.
We have some outstanding new demo footage from a test at Shepperton studios. This was part of a test performed to evaluate the utility of the Tessive Time Filter for an upcoming project. We have a complete writeup about the test as well as, obviously, the footage itself.
Follow the link to the writeup:
Tessive will be presenting a seminar at Cine Gear, New York, covering time resolution issues in motion picture cameras. We'll be introducing a more straightforward way of understanding time resolution capabilities of any motion picture camera (film or digital) and showing footage to explain the concepts. Topics discussed will include time-contrast of motion picture cameras (temporal modulation transfer function) and temporal aliasing and their respective practical effects. Finally, we will discuss how the Tessive Time Filter works with these concepts, although the concepts are important even for people not using the Time Filter. Come find out how to effectively pack more of the real-world into 24 frames per second.
The seminar will be on the main Cine Gear show floor at the Metropolitan Pavilion, Saturday September 24th at 3:30pm.
Tessive will be at Cine Gear Expo in New York City. We will have demonstration footage Blu-ray discs and a live demonstration of the Time Filter, and will have engineering staff on-hand to answer questions about the system. Please stop by our booth, we would love to talk to you. We will be in booth 143.
The Time Filter is available for rent exclusively at The Camera House in the Los Angeles area. We've been working with TCH for a while now when doing demonstrations for their customers, and they've been an outstanding shop. Their technical staff is trained in how to rig the Time Filter on all their systems, and they're an excellent group of people to work with. I highly recommend talking to them if you're interested in the Time Filter system, as they have a good feel for how the system can enable what you may be trying to achieve.
The folks at FreshDV were great to meet at the show. They've prepared a nice video of what they found at our booth. Take a look at their report:
Cine Gear 2011 was a great launch for our product. The people there were wonderful to meet and talk with, and our reception was great. Thank you to everyone who came by our booth and talked with us.
We're very excited that people received our product so well, including a really nice review of our product by Adam Wilt. He summarizes it better than I can!
Tessive has a full-page ad in this month's American Cinematographer magazine, page 57.
Incidentally, the article following our ad on page 60 is a really excellent article by Christopher Probst entitledDecoding Digital Imagers: Part 1. He has an outstanding section explaining spatial aliasing and Nyquist rate in digital sensors. This is exactly the same math the Time Filter addresses, except where digital sensors deal with spatial aliasing, we deal with temporal aliasing (same math, different dimension.)
Think of the Time Filter as an Optical Lowpass Filter, except for time instead of space. Same thing.
Tessive will be at Cine Gear Expo June 3 & 4, 2011. This show is held at The Studios at Paramount in Hollywood. Come visit us at booth S205.
We'll be demonstrating the Time Filter live at the show. We're in the indoor section, so it's easier to see the display. We'll have our engineers onsite to answer your questions and to talk to you about your application.
We're completely aware that the Time Filter is a very unusual system, so we're ready to do our best to help show what it does and why we believe it's a revolutionary device for cinematographers.
