De-Mystifying ‘Crop Factor’

The Crop Factor Conundrum

There has been quite a bit of discussion lately on the crop factor of cameras like the Scarlet. There is a recurring phrase that I’m seeing which goes something along the lines of, “You will need to shoot at 30mm because the lens will become a 48mm.”. Yes, that’s true – the lens will have a 1.6x magnification factor, and 30 multiplied by 1.6 is, in fact, 48 – but guess what? That 30mm will still behave like a 30mm, regardless of if your field of view changes or not. However, let’s take a step back for a second, because we’re getting ahead of ourselves.

Back when I first began making films there was a de-facto camera for indie filmmakers – the DVX100. A plastic fixed zoom lens gave you plenty of framing options, allowing the camera to shoot anywhere you wanted to in glorious 24p. Jump forward to a couple years ago, and we had the 5DMKII, a camera which changed the indie landscape and gave people the added bonus of using custom glass. Here’s the snag, a lot of people that have shot on the full-frame 5D are now moving on to shooting with other cameras and becoming flustered when their 50mm is now an 80mm equivalent in terms of Field of View (FOV). This is nothing new, in fact many cameras have an ASP-C crop sensor, oftentimes Read more

Pulling Focus Remotely with the Redmote

How to Pull Focus with the REDMote

A recent post from Sean Brown shows the method of using a REDMote to pull focus. I’m on the fence about how much time this would save, as well as options for using glass – since it would require your lenses be either electronic, or servo-synched to the camera. In addition, for my Scarlet-X setup, I find things like the REDMote and Sidehandle to be superfluous and unnecessary. However, if you already own one, in addition to some electronic glass – then by all means this could be a handy trick to achieving critical focus quickly without doing a 1:1 zoom or using a tape measure.

How to Unlock Adobe Premiere’s exclusive CUDA acceleration for any NVIDIA card

How to Unlock Premiere CS5.5 and use your NVIDIA video card with CUDA acceleration

Although my beloved NLE Vegas has been using R3D native for years now, there have been some incredible leaps made by Adobe as of late. CUDA acceleration within Premiere CS 5.5 allows the software to utilize the GPU processing power from your video card. This means editing 4k/5k material is faster than ever, and doing things like adding effects and grading is applied in realtime – without a hitch. The only thing standing in between you and taking advantage of the acceleration? Adobe has essentially “short-listed” a few higher powered video cards that will take advantage of CUDA GPU. If you don’t own one of them, then you will have to run CUDA in software mode only, which means you will have to take a serious performance hit.

Until now.

Read on for a step by step how to for “hacking” or “unlocking” Premiere, and get the most use out of your video card. Before you decide to Unlock Premiere for CUDA acceleration – a few caveats to be aware of:

  • Will only work for NVIDIA cards
  • Your card should have at least 1GB memory
  • Also must have DDR3 or DDR5 memory (DDR2 clashes with the Mercury Engine)
  • Works better on Intel chipsets
  • You will need to repeat this process each time Adobe patches Premiere


There are a ton of video cards out there, these are most of the recent offerings from Nvidia. If you are on the fence about trying to run CUDA acceleration with your current card, check out the list below for some extra insight – created by the guys at Studio One Productions.

From Camera through Post – Scarlet-X workflow tutorial

Scarlet-X RAW R3D workflow pipeline

A quick Scarlet-X workflow tutorial

Check out this quick tutorial on an example workflow on the Scarlet-X. It is designed to maintain the native-RAW data for as long as possible throughout the pipeline. This is definitely not an “end all be all” post workflow, but it is a good primer for those of you looking for some direction on a simple, straightforward approach.

TUTORIAL: Camera Projection in NukeX

Camera Projection Tutorial Timelapse for NukeX

A Timelapse Camera Projection Tutorial for Nuke

The time has come, I have decided to put together a tutorial. It was spurred on by this post, in reference to a timelapse shot being animated with a camera in post. The funny thing is that I’ve used this specific technique on my reel opener a few years back. In this tutorial I will be supplying you with the same source footage I’m using as well as the started and finished Nuke scripts. Contextually speaking, I think it’s really helpful to follow along actively – that means downloading the footage I’m using and doing the work yourself at the same time.

This is the first tutorial I’ve done for the blog, and I plan to do many more so please leave comments or messages to let me know what you think. It was done on the fly, so there are plenty of “ums” and “ahs”, and a few times I even get stumped on things. However, this tutorial will teach you both the basics as well as the mentality behind doing 3D projection timelapse setups. Even if you aren’t a compositor, as a visual filmmaker it’s good to know that you have these options in your proverbial bag of tricks and knowing what’s entailed so when you’re shooting in the field you’ll know how to shoot for post.

If you’d like to download the footage and project files I’ve used, get them at the bottom of this post.

Scarlet-X V-Mount (on a budget)

Scarlet-X V-Mount battery setup

Scarlet-X V-mount battery setup - on a budget

Matt Johnson posted a thread over on the REDuser forums in regards to his solution to powering the Scarlet sans Sidehandle / Wooden Camera components. From the thread:


The excellent Cinemaoxide V-Mount Plate Adapter $169
RED XLR to Lemo Cable $120
Generic E-bay V-Mount plate $49
AXRTEC V-Mount 89WH battery $129 (which now appears to be $229 that I go to buy some more … wtf)

I originally got the XLR cable because I needed the RED Lemo to make a custom power cable for my helicopter. So I did that, and put a molex connector on it. So I just had to put a matching molex on the v-plate. No problemo. Total cost including the 1 V-mount battery = $467
