Snapshots - NAB 2008 Day 1

Various images from the show floor

By Adam Wilt | April 15, 2008

Carlos Acosta shows off his prototype shoulder mount for the F23

Carlos Acosta shows off his prototype shoulder mount for the F23 at the Band Pro booth. Fully flexible configuration: grips rotate freely or lock down, and adjust laterally, vertically, and in or out. Shoulder pad is positionable and can be angled; split foam padding velcroed in place allows easy changes, such as a thicker pad on the "outboard" side for better balance. Completely tool-free adjustment and assembly, too; and squeak-free by design. Nice work! Read More

Sony Snapshots - NAB 2008 Day 0

Some highlights of what Sony is showing

By Adam Wilt | April 14, 2008

PMW-EX3 with 2/3" cine lens, Sony HDD recorder

Sony's Juan Martinez gave me a night-before-the-show tour of the Sony booth (really a miniature city; "booth" doesn't do it justice), and here are some of the highlights from a camera operator's perspective. Read More

Locking HDMI cables!

Finally, a non-self-ejecting HDMI cable

By Adam Wilt | April 11, 2008

Left: normal HDMI cable. Right: locking HDMI cable. Note the cantilevered paddle with two tiny retention hooks.

A colleague and I were discussing the sorry state of the physical HDMI connection; we call it a "self ejecting" technology. HDMI cables fall out of HDMI sockets with surprising ease. Fortunately there's now a solution to this problem: a locking plug that works with any HDMI socket. Read More

Review: Camhandle camera support

Renegade tripod handle makes handheld shooting smoother.

By Adam Wilt | April 07, 2008

The $220 Camhandle looks like a tripod handle gone AWOL from its tripod. Its attachment plate bolts to the underside of the camera, and it hangs off the left front side. It looks goofy, but it works surprisingly well. I tested it for two weeks on the notoriously hard-to-handhold PMW-EX1. Read More

RED? Or Cyan?

Why the RED's highlights went cyan and dark, and how to fix 'em.

By Adam Wilt | March 25, 2008

In my unfair comparison of three cameras, I found that RED's overexposed highlights went cyan and got darker than surrounding, non-overexposed areas. Here's why it happened, and how to fix it—it's an easy fix, but you'll appreciate it more if you see what happens if you don't use it! Read More

Working with RED Footage

RED's postproduction tools, and some pitfalls of learning them.

By Adam Wilt | March 21, 2008

For my unfair comparison of three cameras, I had to process RED clips to a greater degree than I had previously, including dealing with odd overexposure artifacts. I relate my experience, both to describe the steps I took to decide on the processing parameters I did, and to show what I ran into when learning to use RED's tools. Read More

EX1 Misfocusing Explained

Some PMW-EX1s show back-focus changes when internal ND filters are used

By Adam Wilt | March 21, 2008

[Updated 2008.03.29] I noticed in my unfair comparison of three cameras that the EX1's outdoor shot wasn't in focus. I was puzzled: I had zoomed in and focused carefully, then zoomed out and shot. Was back-focus that far off? It hadn't been when I last checked it. Hmm... Read More

Three three-letter cameras: EX1, F23, RED

An unfair comparison of three entirely different cameras

By Adam Wilt | March 17, 2008

On March 7th, Tim Blackmore and I visited Videofax, a San Francisco camera rental house. Videofax is unique in the area (as far as I know) in having both a RED ONE digital cinema camera and a Sony F23 HDCAM-SR camcorder. Videofax's Leigh Blicher kindly invited us to come by and take a look, following the DCS RED Event the previous weekend. How could we refuse? Read More

Exporting stills from FCP

Correcting for FCP's assumptions, and a surprising discovery.

By Adam Wilt | March 11, 2008

I recently had a chance to compare the PMW-EX1 with a RED and an F23 (about which, more will be said in coming days). I collected quite a few video clips from the cameras and I'm going through the process of exporting still frames from the two Sonys, using Final Cut Pro. As I want to capture the full exposure range in the stills, there's more to it than just parking the playhead on a frame and doing File > Export > Using QuickTime Conversion. As it turns out, there's also a surprise. Read More

PMW-EX1: XDCAM Transfer 2.5.1 for Mac Released

Fixes clock-mode timecode import bug; qualified for OS X 10.4.11 and higher

By Adam Wilt | March 07, 2008

Sony has released XDCAM Transfer 2.5.1, software used to import XDCAM clips into QuickTime and Final Cut Pro. This version fixes a bug where PMW-EX1 recordings made with CLOCK-mode free-run timecode were not being properly imported, and it is qualified to run both on OS X 10.4.11 and 10.5.x. Read More

PMW-EX1 Update 2

Corrections and details

By Adam Wilt | February 27, 2008

• Adam Van Voorhis of Boston Camera says that the EX1 does indeed supply Y/C video, using the same VMC-15FS cable that works on the HVR-V1.• Reader Mark Weiss ran a formal audio analysis for line-level inputs, with interesting results.My EX1 review has been updated with these tidbits. Read More

HPA Tech Retreat - Day 3, etc.

Cameras, compression & concatenation; displays, distribution, & demos

By Adam Wilt | February 24, 2008

Fox Network's Yves Montane showing one of many display performance plots.

Day 2 Revisited Larry Thorpe and John Galt argued for a more nuanced view of camera resolution, such as MTF (contrast) readings at 200, 400, 600, and 800 TVl/ph, as well as a subjective description, in addition to the standard measurement of the limiting resolution and report on aliasing (see Day 2 pictures). I will be modifying my review methodology accordingly. Read More

PMW-EX1 - use regen timecode

Free run TC may confuse XDCAM Transfer

By Adam Wilt | February 22, 2008

A post on the Cinematography Mailing List yesterday indicates that XDCAM Transfer may not see all the clips on an SxS card if the EX1's timecode was set to "clock" mode, one of the free run options. Sony is reportedly going to address this issue with an updated version of XDCAM Transfer. For now, it appears the safe thing to do for now is to leave the EX1's timecode in regen mode. UPDATE 2008-03-06: Version 2.5.1 fixes this bug. Read More

HPA Tech Retreat - Day 2 (abbreviated)

The website ate my homework.

By Adam Wilt | February 22, 2008

I logged in to PVC and spent 90 minutes writing up the day's events. Apparently I took too long: when I hit "submit" I was asked to log in again, and all my edits were lost. Oops. Yes, I should have copied my work to a nonvolatile file; no, I didn't. I don't have time to retype everything, so I'll have to leave you with a few pictures and some URLs. Read More

EX1 Gammas

Those cine gammas I like? They're not for everyone.

By Adam Wilt | February 17, 2008

When I reviewed the Sony PMW-EX1 camcorder, I raved about its cine gamma settings, derived from the hypergamma curves in the F23, F900/R, and various XDCAM HD 'corders. The email I've been getting indicates that my enthusiasm isn't universal. Let's explore the issue a bit further. Read More

PMW-EX1 Update

A different PMW-EX1 has slightly different characteristics.

By Adam Wilt | February 17, 2008

A few days ago I obtained a new, production-build PMW-EX1 camcorder, serial #103171. Its shipment had just arrived in the USA, so it's a sample of what's shipping now. While it's 99% the same as the pre-production camera I reviewed, it has a couple of differences worth noting—having two samples gives a more rounded picture of the variations you're likely to see in wild, free-range cameras. The analog is cleaner on the new camera, the Lens Info readout is somewhat more accurate, and the lens vignettes less. Read More
