Dr. Jekyll and Mr. Hyde; The ongoing story of Olympus's video implementation in the OMD cameras. revised 3/29.

I had this dream. In my dream I would find a small black camera and it would have a port for an external microphone and another port for set of headphones. The camera would be beautifully designed and as fast as agile as a cheetah. While its primary function would be taking beautiful still photographs it would be a new, "universal" camera that would also make wonderful video content.

This miracle camera would have a built in image stabilization that would make tripods, sliders and other rigs in the video world obsolete. The audio would be surprisingly clear and crisp; easy to use.
Working with it in the field would be a breeze because its perfect EVF would show focus peaking while recording along with a live histogram. It would be so amazing. Perhaps the perfect news gathering and art video video camera.

But then I got the footage back to the studio and that's when the dream started to fall apart....

The first clip I opened was a wide scenic with moving leaves in the distance. The frame was not particularly sharp. Oh yes, it was in focus, but the things in focus just weren't crispy sharp in the way that the video from better cameras like the GH4 is. It looked over sharpened and the victim of some amount of noise reduction even though we were shooting, for the most part, at ISO 200.

I know the fault doesn't lie with the lens because I have terabytes of images from the Panasonic 12-35mm X f2.8 that say otherwise.

The camera is not unusable for video but I have to say that Andrew Reid's rant about the camera's video codec is pretty much right on the money. In other words, buy this camera is you want a micro four thirds camera that takes amazingly good photographs but don't buy this camera as your primary video production camera or you will be crying tears of disappointment and frustration.

Can it be saved via a firmware upgrade? Good lord I hope so.

I gave the camera every chance I could. Lowest ISO. A bright, sunny day. A tack sharp lens. A day without coffee. A mindfulness toward exposure and color balance. The highest quality, All-I codec and much more.

The audio is clean enough, especially given the uncontrolled audio on that location. The colors are perfect. But the whole sharpness thing is just not convincing me. At all. But I did go to all this trouble to piece together a video from the footage so you can see for yourself.

I must say that the big Nikon runs circles around the video capability (at least in terms of video quality) of the EM5-2. And the GH4 makes the Nikon grovel by comparison.

I hope someone will figure out what settings we can use to optimize the camera for shooting much better video because the one thing the video should show is just how good that stabilization is. But it doesn't really matter if the client ends up asking me why the video doesn't look sharp. Right?

They swung. They missed. Hey! Olympus!!! Get working on that firmware. We deserve better looking video than this. Next step? See how the uncompressed video looks via a digital recorder sucking data from the HDMI plug. That's all I have for now.

Added notes: I thought about the material I shot yesterday and I decided to try a few more tests this morning in the studio. I've read a number of different articles and looked again at John Brawley's nice  project, shot with the EM5-2.  I re-tested the camera with all new settings. I've ditched the All-I codec in favor of the highest quality setting ACVHD codec at 60p. I went into the profile settings and created a custom profile that drops the sharpness to minus two, the contrast to minus two and the saturation to minus one.

I turned off the image stabilization, turned off the noise filter and the noise reduction and carefully manually focused the lens with the camera sitting on a stout tripod.

The files were better but not "head and shoulders" better. The drop in contrast and sharpness is definitely helpful and a small bit of post production sharpening in Final Cut Pro X adds back some snap. I also brought the black levels down in post which adds back some contrast but not in the destructive way that in camera contrast control seems to work.

I think I am closing in on a more workable set of parameters for shooting video on this camera. I am hopeful that I'll get it into the ballpark to work as a competent B-roll camera and as a quick, mini-ENG camera for run and gun stuff that's not destined for bigger productions.

If you have suggestions for improving the look of the footage from the Olympus EM5-2 I'd love to hear it. Put it in the comments and we'll share. The camera is a wonderfully fun photography camera. Perhaps we can pound it into shape (with the help of a firmware update or two....) in the near future.
Thanks for staying tuned.

Forget the new cameras. Buy a nice book:

Added notes v2.0: I tested the camera with different settings in the studio today. See video here: https://vimeo.com/123557879

Just a program note. Samsung sent me one of their NX-1 cameras. I will shoot with it and see if it matches the marketing speak.



I resigned from Samsung's beta tester/user program in the middle of last year because I got tired of waiting for a camera that felt like it was aimed at my particular market. I may (or may not) have been premature in my resignation because their new flagship camera, the NX-1, was announced shortly afterward. While I am happy with my current set of cameras I was, initially, very interested in the video capabilities of the new camera. The control set seemed good and I was intrigued by the availability of 4K video and the very fast processor set of the camera.

My initial interest was diminished when I learned about the new codec (H.265) Samsung used in the camera because it's highly compressed in camera and must be converted to an editable file for use in Final Cut Pro X. The resulting converted files can be enormous and the process time consuming. I've since read glowing reports about the image quality and I'd like to see for myself.

As to the still imaging capabilities of the camera-----I think all the cameras on the market are fine for my use. Some menus are better than others and some sensors (like the one in the Nikon D810) are standouts. But most advancements in the still field will be less spectacular than the big jumps in capabilities we saw five and ten years ago.

I am not a sports shooter but if I was I couldn't really test the performance of this camera and it's 15 fps because I only have a handful of lenses for the system and if I was shooting something like the USMS Swimming Nationals in San Antonio next month I would want lenses like the fast tele zoom or the equivalent of a 300mm f2.8 to use in order to really frame tightly while having the lens speed to give me fast shutter speeds as all that work would be handheld.

It's interesting to have three relatively new products in house at the same time. And three such different permutations of photographic tools. I have the EM5/2 with its very nice image quality and color, coupled with the world's best image stabilization. I have the Nikon D810 with its incredibly detailed sensor and massive dynamic range. And I have the NX-1 which shoots fast and offers up the promise of excellent 4K video.

I wish Samsung had sent along two things to help me make a better evaluation of this camera. The first would be their fast, longer zoom. The 50-150mm f2.8. If the camera is going to shine then this lens would go a long way to unveiling that shine. And secondly, on a much more pedestrian note, there was no charge of any kind in the box Samsung sent. I ended up having to buy a USB cable and charging the camera battery, in body, with an old Apple USB phone charger. Hmmmm..... In addition I think every camera maker should supply reviewers with two batteries...

I am waiting for the battery to charge before I begin going through the camera menus and setting it up the way I want it.

It's always a bit awkward to get a review camera within a week or two of having bought a new model camera for one's own system that also wants reviewing. The Olympus got here first so it gets priority in the next few weeks.

Lots of good cameras out there. I guess we'll see which ones are the most FUN to shoot....
