How to get the “24p” look for your live-switched multicam shoot

Our friends at Datavideo recently asked me to write an article called How to get the “24p” look for your live-switched multicam shoot. The article covers many factors involved in accomplishing that goal, including framerate, aperture, shutter speed, depth of field, and menu settings in Datavideo’s digital HD video mixers (“switchers”) and recorders, and also the menu settings in several pro cameras from Canon, Panasonic, and Sony. The included chart explains which of the cameras have a direct HD-SDI output, and which require an optional converter to go from HDMI to HD-SDI to connect to the Datavideo digital HD video mixer. As you’ll see in the article, the approach is quite different from the workflows I normally cover, which are more appropriate when programs are to be edited, as opposed to when they are shot —and potentially broadcast— live. The graphics for this article were done by Victory Elliot of Datavideo Corporation.

AJA’s Io XT w/ Thunderbolt is now available, but it is not Riker: What’s the cover-up?

AJA is now shipping its US$1495 Io XT, AJA’s first Thunderbolt device which I covered in detail when it was first announced in September 2011. Some of you have asked me whether the Io XT is the same as the prototype code-named “Riker” product that AJA showed at NAB back in April 2011. The answer is no. This article will explain why the Io XT is not Riker, review the currently-available Thunderbolt audio/video i/o devices I’ve covered so far (including the Pegasus Thunderbolt RAID), and clarify William Riker’s involvement in the Pegasus cover-up, as well as that of Leo Laporte, who recently declared Thunderbolt to be “D.O.A.” and “too late” on MacBreak Weekly. Even though neither is true, I think Leo had a very good reason to say those things.

Pegasus Thunderbolt RAID5 from PROMISE

As many ProVideo Coalition readers may recall, I have written about disk arrays from PROMISE before, although the last time it was primarily to be used with a computer with an eSATA port. Now that all Mac computers (except for the MacPro tower) use a Thunderbolt port, many are looking for a disk array which will have the appropriate connection and that will be at least as fast as what they got previously with eSATA. In this article, you’ll find my results with the Pegasus from PROMISE, used both with a Mac Mini and a MacBook Air. You’ll also find PROMISE’s official position on journaling or non-journaling with this device, since this was not previously documented anywhere to my knowledge.

PsF’s missing workflow, Part 6: Tépper asks the camera manufacturers…

In parts 1-3 of the PsF’s missing workflow series, we introduced the terms benign PsF & malignant PsF, and revealed the PsF status of several professional AVCHD cameras from 3 manufacturers (Canon, Panasonic, and Sony). In part 4, we did the same with several file-based HD video recorders from 6 different manufacturers. In part 5, we revealed how one recorder manufacturer is offering its own “Band-Aid” software to counteract the inappropriate signals offered over HDMI by many camera manufacturers. Starting with part 7, I’ll begin offering workarounds within several software editing programs, and with at least one external application. However, here in part 6, I am asking questions and making suggestions to the 3 professional AVCHD camera manufacturers who are responsible for creating this entire mess in the first place.

PsF’s missing workflow, Part 5: Átomos hires a stripper!

In part 1 of PsF’s missing workflow, we introduced the new terms benign PsF and malignant PsF (Progressive Segmented Frame), reviewed their vital importance and fragility in post-production, and clarified the PsF status of two Panasonic professional AVCHD/AVCCAM cameras. In part 2, we revealed the PsF status of the Canon XA10 professional AVCHD camera. In part 3, we clarified the PsF status of Sony’s professional AVCHD/NXCAM cameras. In part 4, we covered some portable HD recorders and their PsF status. Now, in part 5, we’ll learn why Átomos (manufacturer of the portable HD recorders creatively called Ninja and Samurai) has hired a stripper to help correct the malignant PsF signal that many cameras output via HDMI.

PsF’s missing workflow, Part 4: file-based HD video recorders

In part 1 of PsF’s missing workflow, we introduced the new terms benign PsF and malignant PsF (Progressive Segmented Frame), reviewed their vital importance and fragility in post-production, and clarified the PsF status of two Panasonic professional AVCHD/AVCCAM cameras. In part 2, we covered the PsF status of the Canon XA10 professional AVCHD camera. In part 3, we clarified the PsF status of Sony’s professional AVCHD/NXCAM cameras. Now, in part 4, we’ll cover some file-based recorders (from manufacturers like AJA, Átomos, Blackmagic, Convergent Design, Datavideo, and Sound Devices), their PsF status, and their purpose in your system and workflow.

Mac Mini for pro video editing: a field report from Guatemala

Many readers of ProVideo Coalition magazine may recall my recent article Mac Mini w/Thunderbolt: preferred platform for many new editing systems. However, some of the readers had doubts, and one naysayer even dared to comment via LinkedIn: “This is hilarious garbage. No serious editor, in their right mind, would do this.” Another commenter via LinkedIn supposed that it would stand up for standard-definition video editing only, but would never work for HD 1080p editing. Fortunately, here is a detailed report from a very serious commercial production company in Guatemala, that has recently replaced two MacPro towers with Mac Mini i7 with Thunderbolt, together with a Thunderbolt RAID5 disk array, and a Thunderbolt-based professional audio/video i/o device. Here you’ll see the exact software and hardware configuration used, performance, and enthusiastic comments from the editor. On the other hand, you’ll even learn where not to use a Mac Mini.

DaVinci Resolve training at Staff/HDTV in Guatemala

I just returned from the Republic of Guatemala in Central America, where I interpreted a class for David Catt, the original product manager at DaVinci Systems. (Since then, DaVinci Systems was purchased in 2009 by Blackmagic Design). David Catt taught 7 Guatemalans how to perform grading, including color correction and more using DaVinci Resolve. The client who recently purchased the new Mac-based DaVinci Resolve system is Julio Borrayo, president of STAFF HDTV/Alta Definición, which produces high-end TV commercials in Guatemala. This article explains the details of the system they purchased (hardware + software), installation and preparation, main points covered in the class, and the students. David Catt has agreed to join us on an upcoming episode of TecnoTur to discuss grading and the differences between different DaVinci Resolve configurations.

Blackmagic breaks Thunderbolt price budget with US$299 Intensity Extreme

At IBC in Amsterdam, Blackmagic has just announced its second Thunderbolt audio/video i/o interface, the US$299 Intensity Extreme. For about 70% less in price than Blackmagic’s first Thunderbolt product, the Intensity Extreme is also the first bus-powered a/v Thunderbolt interface, although not the first bus-powered device (since Matrox’s Thunderbolt adapter is bus-powered, but it is not an audio/video interface itself, but the connection to one). When connected with a laptop (i.e. MacBook Air or MacBook Pro), the Intensity Extreme will be powered by the laptop’s internal battery via the Thunderbolt connection. This article will describe exactly what you’ll get —and what you won’t get— if you choose the US$299 Intensity Extreme interface from Blackmagic, and its availability.

AJA announces Io XT interface with Thunderbolt at IBC in Amsterdam

Today AJA announced and is showing its new Io XT audio/video interface with Thunderbolt at IBC stand 7.F11 in Amsterdam, Netherlands. Unlike other Thunderbolt-capable professional i/o interfaces from other manufacturers which I have covered earlier this week here in ProVideo Coalition magazine, the Io XT from AJA is the first and only one so far to offer loop-ability (aka “daisy-chaining”) to other Thunderbolt peripherals or even standard DVI/HDMI monitors via an inexpensive adapter or cable (under US$30 in most cases). This first look at AJA’s Io XT will cover its features, specs, and pricing.

Matrox adds optional Thunderbolt connectivity to existing MXO2 family interfaces

Matrox is the first (and so far, the only) manufacturer of professional audio/video interfaces to offer the possibility of adding Thunderbolt connectivity to any of their existing products which are already in the field. Matrox now offers this capability for any of the MXO2 family of interfaces, which currently include the MXO2 Mini, MXO2 LE, MXO2 (original), and MXO2 Rack. Since almost the beginning of the MXO2 family, all of the interfaces have been available either with (or without) Matrox’s Max option, which performs hardware-based accelerated H.264 encoding from within popular professional video editing and encoding applications, and with a choice of either PCIe or ExpressCard/34 interface to a host computer. As first shown at NAB 2011 and now delivering in September 2011, Thunderbolt is the third available option, allowing connection of any Thunderbolt-capable Mac. This article covers how this works, what it means, and what the upgrade will cost you (or the price of admission if you don’t yet own any MXO2 family interface).
