Undisclosed Project: Elevation

Prep for the yet-to-be-announced Shakespearian feature continued last week. Tuesday and Wednesday saw me on Zoom calls with the producers – discussing camera kit quotes – and the costume designer. “Will we see enough of his face through this headgear?” was a question for the latter. She in turn asked how white a white coat should be, and how dark surrounding characters should be to make one person in black stand out. Difficult things to quantify, but important.

The week’s main event was another two-day recce with the director and production designer. The designer had produced beautiful and detailed mood-boards for every room, and had even started to bring in the right furniture and test paint colours. The main aim of the recce was to discuss and sign off on his decisions so that decoration and dressing could step up to full steam.

As we moved from room to room, trying to keep in story order whenever possible, the director revealed lots of his thoughts about the tone and key beats of each scene. I was pleased to find that these were largely in a similar vein to notes I had amassed on my own spreadsheet. And when they weren’t in sync, that was very useful to know at this stage! For most scenes I showed him a reference image or two, again from my spreadsheet, to double-check that we were on the same page.

We were visited during the recce by a grip who had come to see whether a crane would fit into our main location, and if so what kind of crane and whether it could achieve the shots we wanted. I had envisaged using a Giraffe like the one we had on The Little Mermaid, but the grip suggested we would be much better off with a 23ft Technocrane and a basic remote head, as this can telescope and retract rather than only sweeping around in an arc. We measured the distances to see where the camera could end up, and then I used Artemis Pro – a director’s viewfinder app – to see what framing that would translate to with various lenses. One of our most important shots should just be possible at the full extent of the arm, combined with the full range of a 25-250mm zoom.

Whether the budget can afford the crane, however, is yet to be confirmed. This week I am due to conduct camera and lens tests, and once I’ve made a decision on those then we will know what is left for fancy grip equipment!

The only other thing to happen last week was the hiring of a data wrangler. Since I lined up the 1st and 2nd ACs quite soon after my own hiring, the camera department is now complete.

Converting Blackmagic Raw Footage to ProRes with After Effects

My 4K Blackmagic Production Camera

One of the big benefits of the Blackmagic cameras is their ability to shoot raw – lossless Cinema DNG files that capture an incredible range of detail. But encoding those files into a useable format for editing can be tricky, especially if your computer won’t run the processor-intensive DaVinci Resolve which ships with the camera.

You can usually turn to the Adobe Creative Suite when faced with intractable transcoding problems, and sure enough After Effects provides one solution for raw to ProRes conversion.

I’ll take you through it, step by step.  Let’s assume you’ve been shooting on a Blackmagic Cinema Camera and you have some 2.5K raw shots which you want to drop into your edit timeline alongside 1080P ProRes 422HQ material.

1. In After Effects’ launch window, select New Composition. A dialogue box will appear in which you can spec up your project. For this example, we’re going to choose the standard HDTV resolution of 1920×1080. It’s critical that you get your frame rate right, or your audio won’t sync. Click OK once you’ve set everything to your liking.

step1

2. Now go to the File menu and select Import > File. Navigate to the raw material on your hard drive. The BMCC creates a folder for each raw clip, containing the individual Cinema DNG frames and a WAV audio file. Select the first DNG file in the folder and ensure that Camera Raw Sequence is ticked, then click OK.

step2

3. You’ll then have the chance to do a basic grade on the shot – though with only the first frame to judge it by.

step3

4. Use Import > File again to import the WAV audio file.

step4

5. Your project bin should now contain the DNG sequence – shown as a single item – along with the WAV audio and the composition. Drag the DNG sequence into the main viewer window. Because the BMCC’s raw mode records at a resolution of 2.5K and you set your composition to 1080P, the image will appear cropped.

step5

6. If necessary, zoom out (using the drop-down menu in the bottom left of the Composition window) so you can see the wireframe of the 2.5K image. Then click and drag the bottom right corner of that wireframe to shrink the image until it fits into the 1080P frame. Hold down shift while dragging to maintain the aspect ratio.

step6

7. Drag the WAV audio onto the timeline, taking care to align it precisely with the video.

step7

8. Go to Composition Settings in the Composition menu and alter the duration of the composition to match the duration of the clip (which you can see by clicking the DNG sequence in the project bin).

step8

9. Go to the Composition menu again and select Add to Render Queue. The composition timeline will give way to the Render Queue tab.

step9

10. Next to the words Output Module in the Render Queue, you’ll see a clickable Lossless setting (yellow and underlined). Click this to open the Output Module Settings.

step10

11. In the Video Output section, click on Format Options… We’re going to pick ProRes 422 HQ, to match with the non-raw shots we hypothetically filmed. Click OK to close the Format Options.

step11

12. You should now be back in Output Module Settings. Before clicking OK to close this, be sure to tick the Audio Output box to make sure you don’t end up with a mute clip. You should not need to change the default output settings of 48kHz 16-bit stereo PCM.

step12

13. In the Render Queue tab, next to the words Output to you’ll see a clickable filename – the default is Comp1.mov. Click on this to bring up a file selector and choose where to save your ProRes file.

step13

14. Click Render (top far right of the Render Queue tab). Now just sit back and wait for your computer to crunch the numbers.

step14

I’ve never used After Effects before, so there are probably ways to streamline this process which I’m unaware of. Can anyone out there suggest any improvements to this workflow? Is it possible to automate a batch?
