Should Professional Editors care about FCPX (again)?

Sam Mestman thinks so: he's betting his company on it. I think he's right. Attend his demo 25 January and make up your own mind.

By Adam Wilt | January 15, 2014

Last October Kevin McAuliffe told us in two articles that Final Cut Pro X wasn't worth caring about: "FCPX is still not ready for professional use". He caught a lot of crap for saying so, but he was right... in a very constrained context (which, if you read his rants, he carefully... Read More

Quick Takes: Phase-detect AF coming to Canon C100; DaVinci Resolve 10 released

By Adam Wilt | November 11, 2013

Two stories of note from this past week:

Canon's C100 Large-Single-Sensor AVCHD Cine Camera will be upgradable to dual-pixel phase-detection autofocus, similar to that used on the EOS 70D DSLR... but better.

Canon's update should improve AF considerably. Note... Read More

First Look - Luxi Incident Metering Attachment for iPhones

A Kickstarter-funded photosphere turns the iPhone / iPod touch front camera into an incident meter

By Adam Wilt | August 24, 2013

Back in late February, a chap named James Flynn put up a Kickstarter page for Luxi: "Luxi turns your iPhone into an incident light meter." He hoped to raise $10,000 to build the thing; 45 days later he had $120,921. I threw some money in the pot in mid-March, and earlier this month two Luxis... Read More

OS X: Fixing AVCHD media to avoid the dreaded “CANNOT OPEN”

OS X is too picky for its own good with AVCHD media names. Here's how to fix things.

By Adam Wilt | May 10, 2013

If you’re using OS X and you copy AVCHD media folders to a NAS (network-attached storage) or a case-sensitive disk, you may run into problems: opening the media in 10.8’s Finder gives you “CANNOT OPEN” instead of a clip browser, FCP X can’t see the clips, and so... Read More

I was able to get a few pictures of these new beasts, which Videofax has kitted out using third-party support accessories and a couple... Read More

Breaking news: Vantage One T1 Primes

Nine T1 PL-mount cine primes!

By Adam Wilt | November 26, 2012

Image from Film and Digital Times used by permission.

Are you into super-shallow depth of field? Do you think modern lenses are too "clinical"? Shoot PL-mount? Vantage, the folks who make Hawk anamorphics, are introducing a new line of nine spherical prime lenses, from 17.5mm through 120mm. They all open up to T1, with the knife-thin DoF and the organic look that implies, and—wait for it—they'll be available in a partially-uncoated version for lower contrast and increased flare.

Review: Induro Hi-Hat

A new take on the venerable hi-hat: micro baby legs.

By Adam Wilt | November 16, 2012

This review will be short and sweet, just like its subject: Induro's Hi-Hat is a stubby little tripod that brings your camera down to earth with more flexibility and versatility than a traditional hi-hat or low-hat can offer, while still allowing the traditional mount-it-on-a-board use that filmmakers are familiar with.

Review: Benro Video Tripod Kits

Benro has a new line of affordable fluid-head tripod kits. Are they any good?

By Adam Wilt | November 16, 2012

Chinese photo-equipment company Benro has been making tripods and heads under its own name for the past decade. At NAB 2012 they introduced a new line of kits with fluid heads for video use, and these started shipping in October. Benro's US distributor sent me three representative kits, with both aluminum and carbon fiber sticks and three different fluid heads, to test and compare. Read More

DSLR Audio: Do YOU know where YOUR sync is?

Another reason why you might prefer a real video camera...

By Adam Wilt | November 06, 2012

Recently one of my L. A. buddies, photographer and director Ralf Strathmann (Flash-based website), shot a feature using Canon 5D Mk IIs. He found to his surprise that the audio and video recorded by the cameras weren't in sync, with sound two frames ahead of picture. A discussion two weeks ago on the Cinematography Mailing List also debated DSLR A/V sync, or the lack thereof. I decided to have a look into it. Read More

Mikey Digital on an iPhone 4S running Voice Memo.

Blue Microphones recently started shipping the Mikey Digital, an add-on stereo mike for iPhone 4, iPhone 4S, iPad, iPad 2, iPad 3, and iPod touch 4G (iOS 6 only), and Blue offered to lend me one for review. I'd been intrigued by earlier, analog Blue Mikeys at trade shows, so I jumped at the chance to look at—and listen to—this digital descendant. Read More
