RED ONE Workflow in detail

Dennis Alaniz is a Chapman alum and former student of mine who has been a very busy editor and on-set DIT.   As I have said many times, the new camera technology has created tremendous opportunities for young filmmakers to get hired and get on-set and go to town managing data, looks and how the final edit is going to be made.   It takes organization, discipline and passion because there is a mountain of raw data out there ready to be corralled and whipped into shape.   I think you will find his breakdown to be very useful.

RED WORKFLOW by Dennis Alaniz                                    August 5, 2010

DISCLAIMER: As an emergent technology, a RED workflow that works today will likely need to be refined in as short a time as a month. The workflow I describe below suited my particular situation at my particular time. It is my hope that what I learned will serve as a guideline for any future workflow using RED technology.

And remember, the newer the technology, the bigger the risk. It hurts living on the bleeding edge. Trust me! The list below is what we specifically worked with. If you can get better, faster machines, do it!

Hardware

2 RED Cameras with Mysterium X Sensor (30.4 firmware and 30.5 firmware)

Please do what you can to have the same firmware on both cameras. It can save you a major headache later in the process.

6 16GB Flash Cards for RED Camera

You need more! Ideally, you would never reuse a card. We were stressed to keep cards clear so the film could keep shooting. An external drive is also an option, but moving parts make things much more precarious.

2 MacBook Pro Laptops for DIT

A laptop of decent speed that can connect to firewire or e-sata is necessary to keep cards copied and cleared. It doesn’t need to be laptops, but you should have one or two separate machines to copy the flash cards over to external drives. Laptops are more helpful if you need to stay mobile.

2 Flash card readers

As many as you need and can plug in to your machines. Just keep flash cards copied and empty IF the data has been verified by an MD5 after the copy.

Mac Pro (8 core, 16BG RAM) for Asst. Editor

You’ll need a fast machine to facilitate copying files, rendering video, and keeping several apps running. Most importantly, you need to stay as much in pace with the production as possible.

REDRocket video card

An extremely expensive accessory, but if you can afford it, it will keep you moving at an impressive pace and allow you to manipulate and play back the image with very little performance hit. Something your Director and Cinematographer will thank you for. Every single day!

E-SATA Card for Asst. Editor

The $20 from Best Buy will suit you just fine. As long as you’ve got a lot of very fast connections (that are hot swappable) to your Mac Pro because you’ll be shuffling a lot of drives.

6TB Redundant storage

8TB G-TECH RAID 5 with G-TECH E-SATA Card (not the same card as listed above)

6 2TB G-TECH External RAID 0 (Set Drives)

These six drives were broken into groups of three: A, B and C. When one card was copied off, it was copied to both drives in a group at a time. (ex. Card 001 was copied to Drive A1 and A2. What card was copied to what group depended entirely on availability. This redundancy will be explained in the Appendix 1 below. Exactly how much you’ll need depends on a great many factors. 6TB barely suited us. I would have been happy to have an additional 2.

6TB Work Storage

2 4TB G-TECH External Non-RAID

2 1TB External FireWire

The two 4TB drives were my personal raw RED storage, Import/Export, SFX Drives. Again, I’d have been happier with about another 4TB. This redundancy is also explained in Appendix 1. The 2 1TB were used as an emergency back-up to the editor’s drive and as a delivery drive respectively. Ideally, you’ll have a back-up drive onsite and offsite for every machine being used.

Optional Hardware

Laptop and USB External Drive (at least 500 GB)

Delivering low res dailies for use on set (more on this later).

Software: RocketCine-X (depreciated)

Viewing dailies and transcoding footage

REDCine-X

Transcoding for upres (the official replacement for RocketCine-X)

FileMaker Pro

Maintaining a shot database

ClipFinder (2.2 and 2.5)

Exporting shot information and still images for use in FileMaker Pro. Different versions will be explained later.

R3D Data Manager

Used to verify the MD5 of your clips after they’re copied off the card. This program is a must!

Final Cut Pro (Or the NLE of your choice)

Shot organization and synching dailies

Workflow

To reiterate the critical pieces of data from above, we shot on a newer model RED with a Mysterium-X sensor. That alone drastically altered my intended workflow. I won’t go into all the technology as to why, but simply say, know the color science of your camera! The Mysterium-X uses a new color science called FLUT and was the specific reason for this workflow.

Knowing the color and gamma space your finishing in isn’t necessary, but it saved me a step early on in the process. Whatever you choose, be consistent in it when transcoding from RED. We were working in a color space of Camera RGB and gamma space of REC709. (ADDENDUM: Changing post houses last minute may facilitate rerendering all the red footage with a different gamma space. This is still an unknown)

As the director was also editor for this film, I was required to work from a trailer on set. This made my job easier and allowed me to keep pace with the production. Equipped with the above hardware, our day-to-day workflow is detailed below.

On-Set Workflow:

Footage shot on the RED to Flash Cards.

Footage offloaded using R3D Data Manager to verify MD5 and to duplicate on two of the above 2TB set drives.

Data from one of the two set drives is copied to one of two 4TB G-TECH Non-RAID drives. I was always delivered only A2, B2 or C2. This was to ensure that, if I corrupted a drive, I never corrupted the other in the group.

Using RocketCine-X (Now depreciated), newly copied footage is transcoded to 720p Proxies and saved to USB external 500GB drive. Footage is then transcoded again to 2K and saved on the 6TB G-TECH RAID.

720p footage is loaded into Final Cut. Organized into bins and properly labeled.

Raw RED footage is again loaded into clipfinder to export an XML of all data along with highest quality screen captures, one every second.

XML is imported into FileMaker Pro. Cross referencing organized footage in Final Cut, missing data (i.e. Shot name) are filled in FileMaker Pro.

Up to 3 screen captures per shot are added to the FileMaker Pro database for visual reference.

At the beginning of the next day of shooting, audio from the prior day is delivered and copied to the 6TB RAID

All footage captured the prior day should be in its own daily Final Cut Pro project. The prior day’s media is then reconnected to the 2K media on the 6TB RAID. This “online” project is synced to the newly received audio.

The day begins again from the top.

In post, the workflow isn’t so dogmatic. Some shots have been pushed in beyond what the 2K image can handle and so is being reconformed to a 4K online. VFX shots are also being reconformed to 4K.

4K Upres:

Place all footage to be reconformed into a new timeline.

Export XML from Final Cut.

Using ClipFinder 2.5 (THIS IS IMPORTANT! ClipFinder 2.2 CANNOT handle the following steps!) import the XML using the Import FCP XML with relevant settings defined (ex: VFX requires 8 frame handles).

Replace the MOV with the R3D media.

Send everything to a RedCine-X Bin. (This, specifically, is what you need ClipFinder 2.5 for)

Double check the color settings are correct for each clip and export them as 4K files (VFX clips go to their own drive, online 4K shots go back to the 6TB RAID).

For footage to be reconformed in FCP, go back to ClipFinder and choose Run Conform on FCP XML file. Make sure you point the application to the folder with the NEW 4K FOOTAGE!

Import this new XML into FCP. The newly imported clips can now be dropped into the show timeline and will be pointing to the higher res 4K footage. Double check that your push-in, repositions, filters, etc., match the clip it’s replacing. Resting it above the 2K allows you to keep the 2K as a reference in case something goes wrong.

The advantages to this particular workflow (on and off set) are:

It allowed me to run onto set with the low res proxy to answer any continuity questions with great ease.

I was able to show the director, cinematographer, costumer, etc., high res footage approximately 1-2 hours after it was shot. Using RocketCine-X, I was also able to grade some shots on the fly to verify we were on the right track.

Finding shots in the FileMaker Pro database was easy as I could cruise the database looking for a particular image, or search by day it was shot, scene name, etc.

Editing online could begin immediately. While on set, I put together a teaser to show the crew incorporating footage shot as recent as the day prior.

The delivery file to the post house will require no reconform later down the line. They intend to take our semi-graded 2K ProRes file, with an EDL to notch out the shots, and do any touch-ups to that file.

Reconforming to a 4K image is extremely easy as I have the raw RED material handy and, since the file names were honored, sending it to RedCine-X is painless and the REDRocket cuts down transcoding time drastically.

Disadvantages to this workflow are:

As the 6TB drive is connected to the editor’s machine and not mine, streaming 2K over an ethernet cable is not reliable. Pulling that much data and hitting the drive from two machines can cause a massive performance hit.

Sharing Final Cut projects isn’t easily done. To solve this, any changes I made on my end had to be copied to the editor’s project by hand on his machine to ensure he wasn’t editing the same project at the same time.

Editing online takes a LOT of hard drive space and render times can escalate quickly. To create a DVD of the full timeline can take anywhere between 5 and 8 hours.

Here’s a link to the FileMaker Pro template I used on set. It’s hard coded to extract the reel name based on where I had the raw RED files stored, so that will need to be modified to suit your needs. The included XSLT file is to handle the translation from ClipFinder’s particular XML format into something FileMaker Pro can handle. When you import an XML file into FileMaker Pro, you’ll see where to use this XSLT file. (NOTE: This has not been tested with an XML from ClipFinder 2.5)

That, in a nut, is the majority of my workflow . There were a number of subtleties in variation I had to employ to accomplish any particular tasks (ie. uploading for web, creating specific screener DVD’s) and can describe any of those in greater detail if you need assistance with your own workflow.

Appendix

The intent of our redundancy was to ensure integrity and safety of all critical data. After the film finished shooting, there were now 8 drives with 3 different copies of all the raw RED footage: one copy was split amongst drives A1, B1, and C1, another on A2, B2, and C2 and the third was split among my two 4TB drives Cold Storage – 1 and Cold Storage – 2. My two drives served as the drives I would use when, for whatever reason, I had to return to the RED footage to re-render anything. The two remaining sets were separated from each other and both put in a safe place in different parts of town. This ensured that the destruction of no one building would completely destroy the footage.

RED Digital Cinema: NAB 2010

Despite the hassle at the door, one Red User got in and provided valuable insight as to the future of Red and it’s lightweight iteration, Epic.

Michael Cioni defends the Red “ Shooting 4K for online is not overkill!”

“In the web filmmaker community, a recent debate has been whether the next generation of Ultra-High Resolution is advancing too fast for the creatives and the Internet to keep up.”

Chud.com presents an article that is both enlightening, yet cautionary as it offers commentary by one of the leaders in Red Camera Post workflow, Michael Cioni, founder of Lightiron Digital.

Check out the feedback comments at the end of the blurb as they reveal a deep seated dissatisfaction by some end users over transcoding and conforming.

Michael Cioni will be leading a RED CAM workshop in Venice California, Saturday April 24th. http://filmschool.ph/LAworkshops
