The New Blackmagic Pocket Cinema Camera 4K Is Here


Blackmagic introduced the Pocket Cinema Camera back in 2013 and after its release I had several opportunities to use it on short film shoots. You can find my initial impressions here (Bear in mind that some of the issues I had with the camera were addressed with later firmware updates).

Now, five years later, Blackmagic has announced the new Pocket Cinema Camera 4K. I've been browsing through Twitter and industry blogs to learn more and, on paper, there's a lot to like.

  • Price Point - At only $1,295 Blackmagic aims to undercut cameras like the Panasonic GH5
  • Battery - Short battery life was one of my biggest complaints about the original Pocket Cinema Camera, but the new 4K version will use the Canon LP-E6N batteries. So, I'm hopeful that the new camera won't drain battery power nearly as fast.
  • Full HDMI port - No more using adapters to attach external monitors to the camera
  • Multi-function grip - This should make it easier to shoot hand held than its predecessor.
  • Monitoring LUTs - Unless you had an external monitor with a built-in 3D LUT paired with the original Pocket Cinema Camera, you had to look at a gray, flat image if you chose to shoot in Film Mode.

Here are two first-look videos from the NAB Show floor:

12 Tips For Getting a Better Green Screen Key

Since we're about a month away from the 2015 NAB Show, I thought it would be timely to look back at some of the useful information I came away with from last year's sessions.

In this post, I want to talk about green screen workflows. Those of you who have worked on green screen shoots before (and that's probably a majority of you) know how important it is to properly light your green screen and light and place your talent. Otherwise, the edges of your key will be blotchy and your talent will have a green glow.

I had the opportunity to attend Jeff Foster's class, in which he provided some extremely valuable information for setting up, lighting, and shooting green screens. By adhering to his tips, you can get a nice, clean key in post-production.

How to Expose Properly

Proper exposure is crucial if you want to retain as much information in your shot as possible. If you happen to overexpose the frame and clip the highlights, that information is lost. No amount of correction and grading will bring back lost highlights. Conversely, more can be done to salvage lost shadow detail, but the trade-off is more noise, grain, and artifacting (depending on the camera and how crushed the shot is).

This is why using a waveform monitor is so important while on set. It reads luminance values from black (value=0) to white (value=100). Proper exposure means that everything within your frame falls above 0 and below 100. A good rule of thumb is to keep your midtones around 75. This is why, when I use zebras on my EVF, I keep them set to 75. Then I open up the iris enough to see a small amount of zebras on the forehead and/or cheekbones of my subject. That tells me that the midtones are hitting right around 75 IRE.

Another great way, besides using the zebras, to ensure proper exposure, is to use a middle gray card. Where middle gray should hit on your waveform monitor depends on the camera. The following information comes from Jem Schofield of The C47:

  • Canon (for the C100, C300, C500) recommends that middle gray hit around 33 IRE.
  • Arri recommends 38 IRE, but 40 if you are shooting LOG.
  • Middle gray should fall around 50 IRE if you are using the Standard picture profile on the 5D Mk III; 40 if you are using the Neutral profile.
  • Middle gray should fall around 40 IRE if you are using the Blackmagic Pocket Cinema Camera in film mode.

Why RAW and LOG Recording Are So Important


This post is a series of notes I made during one of my NAB sessions back in April. This particular class, taught by Robbie Carmen, centered on both RAW and LOG recording; the definitions of each, the differences between the two, reasons why you should shoot in either format, things to consider when shooting RAW or LOG, production and post-production workflows, and some general guildelines.

Regular Video

  • Parameters are baked into the signal (white balance, exposure, color space, codec, etc.)
  • Easy to use
  • Limiting for maximum flexibility in postproduction

Why Should You Care?

  • You want the best looking image possible
  • It's all about capturing a ton of information and giving you the most flexibility in post
  • Capturing the most dynamic range

What RAW Recording Gives You

  • You can avoid sensor processing
  • Ability to change any exposure/color parameters on the fly
  • Avoid the pitfalls of regular video

Workflow Thoughts

  • Shooting RAW and LOG can complicate on set workflow
  • There's a need to normalize content for on set viewing (Remember that RAW and LOG will look extremely flat coming directly off the camera, which can confuse clients who are unfamiliar with the format.)
  • Potentially the need for additional on set personnel
  • Potentially the need for capable monitoring equipment
  • High capacity, fast storage is needed


  • A DIT manages data and workflow while on set.
  • Develops LUTs (Look Up Tables) and uses them
  • Potentially implements hardware
  • Potentially color corrects and grades while on set

The Onset Colorist

  • Grades from camera transfers on set
  • Grades live from the camera feed
  • First line of defense in processing footage - a) grades that can transfer to post, b) creates an initial look setting

Onset Viewing

  • Proper monitoring for LOG footage is essential
  • Many monitors are capable of supporting LUTs directly

RAW and LOG Are Not The Same

  • Logarithmic recording is a way of capturing an extended dynamic range in a scene
  • Multiple LOG curves exist for different manufacturers
  • Gamma is converted in post-production
  • RAW recording bypasses the sensor processing decisions, so nothing is baked in


  • RAW is not video. It's information; data
  • Color is produced on most cameras by filtering each pixel to produce RGB
  • The pattern of this filtering is called a Bayer Pattern which most cameras use
  • RAW data is in this array
  • Patterns differ, depending on the camera
  • All footage must be debayered in order to view it.
  • Not all RAW is created equal
  • RAW data is often compressed, some cameras more than others
  • Bit depths can range from 12-16 bits depending on the camera
  • 16 bit RAW is not the same fidelity as 16 bit LOG
  • RAW bit depth does not apply well to the way we view images
  • While processing RAW you can often place it into the color space of your choosing and assign a gamma curve
  • Develop RAW to a starting point where you have the greatest flexibility in grading. Don't use RAW control as a principle form of grading.


  • LOG is processed footage
  • LOG is a particular type of Gamma curve
  • Manufacturers have their own flavor of LOG
  • Don't confuse "flat" with LOG
  • Shooting with reduced contrast, saturation and sharpness can help but it's not LOG recording
  • Many cameras try to approximate LOG recording


  • LUTs have been the source of a lot of confusion
  • It transforms data into a specific color space
  • Technical LUT - the LUT you would put on a monitor
  • Creative LUT - a look or grade that a colorist can save and then be applied to any footage
  • Output LUT - profile a film stock, place it into your system so your grade matches the film stock you will output to.

You don't have to go to a LUT right away when bringing in the footage to your NLE. Just simply grade it when you drop it in. You don't have to drop a LUT on it. First, adjust the curves with a waveform monitor and then bump up the master saturation.
