Short notes from "El Premio" Post-Production
Short Notes from "Cave of Forgotten Dreams" Post-production
by Kaspar Kallas
This 3D project by Werner Herzog and DoP Peter Zeitlinger, started for me by a phone call in the late evening offering me a DIT job on SI2K shoot in south of France. I had 10 minutes to decide. The rest is a documentary film…
On set Iridas tools were irreplaceable because we lacked proper tools to make this technical very demanding job on the first week of shooting. So there was quite a lot of duct tape and spit solution used to acquire the footage needed. This in turn required good tools for QC, to be certain that we would have something that we can use in a film.
The shooting period was split into two weeks of shooting with week and a half in-between. I used the in-between time to make a very solid side-by-side rig for use inside of the cave. There could be no adjustment screws as they would have become loose when the crew was climbing in and out of the cave. Because of Iridas native support for cineform RAW we could watch the dailies instantly when we left the cave to make necessary adjustments to our gear, workflow or both.
On the second week we had 2 sets of cameras, one would reside in the mirror rig while other were used for side by side. So when we needed to change in the interview we would just switch the heads to another setup while keeping the same recorder.
The production was extremely fast paced, up to 2h of footage daily. The postproduction was light-speed. I had exactly 2 weeks from the day I got the locked cut to the premiere in Toronto International Film Festival.
About 12minutes of the final 90minute film is non-synced go-pro cameras. I already knew the problem from set, as part of it was shot with one camera upside down the 3D was unwatchable because of rolling shutter tearing the images apart. There really are only 3 possible solutions to the problem today. Try to render a depth map based on original stereographic setup - extremely complicated because of the rolling shutter, compression and lens distortion artifacts. Use bezier shapes to push in or pull out parts of the image. Just use plain 2D slightly pushed into the screen.
The last option is worst, because it really pronounces all the problems with 3D cinema and leaves one wonder why to wear those geeky glasses in the first place. The first option was too time consuming and results were not really predictable.
2 days before screening, after 1st pass render I notice a bug, all the frames are not the correct frame size - a bug in beta version. Iridas was very prompt to deal with the problem in less than 12h I have a new build and everything is on the way again. The final version for the screening in the theater is taken to Toronto by Director himself just hours before screening as we hit another bug, this time in EasyDCP software that was also cleared within hours.
After 2 weeks almost no sleep, the show starts, I can breathe easily - the film is there, everything seems to look correct. 10 minutes before the end of the film the image goes black, sound continues for a moment and then it is stopped. Silence.
It turned out that it was the very first public screening in the Bell Lightbox for digital 3D and somebody had accidentally turned off the the AC for the projector and bulb had overheated.
The golden rule of filmmaking: if something can go wrong, it will go wrong, alligators or no alligators!
Digital Sputnik: The “New” Post-Production
INTRODUCTION

I had the opportunity to work with Kaspar Kallas on Argentina last year, during the shooting of the movie “El Premio” (The Prize) by Paula Markovitch. Kaspar is the founder of a very small post-house on Estonia. And by the time we were working on “El Premio” he was finishing the post-production of Werner Herzog’s 3D documentary “Cave of Forgotten Dreams”. Both movies participated on this year’s Berlinale.
Kaspar and his brother Kaur, founded the company 3 years ago. With only 3 employees, they are focused all their efforts on developing new tools and workflows to aid the postproduction so it can be more creative and less technical. With more than 10 years of experience and knowledge applied that go from edition to VFX artistry, they have created a reliable company that is getting closer to what seems to be the future of movie making.
This “New” post, as Kaspar calls it, has a simple premise: a “One man’s” support to the DoP from pre production to the final screening. This would be the only responsible for every step and every decision made on the way, from the picture being recorded to the final output. “Responsibility in this case means if I make a mistake, I have the means to fix this situation down the line in production pipeline. So the Producer, Director and DoP have only one person to deal with: Me. No meetings. No blame game.” says Kaspar.
The “New” Post
by Kaspar Kallas
There is actually nothing new about having a small and effective team for filmmaking. Then again it has always been a compromise of tools and possibilities. It has more to-do with quality and technology access, rather than innovation.
Technology keeps marching on and there is nothing new about that either. The only thing that keeps chaining is the time window of professional to prosumer. The tools that are bleeding edge in a moment are already in prosumer access within months of initial release in the highest end software/hardware. Then again there are some tools that are never available for highness systems.
Access to tools does not separate professionals anymore. Once again the industry is calling out for Hero's, artist who are capable moving fast and efficiently in post-production pipeline (Hero suite, used to be very expensive hardware and software combination used for film and television finishing by a Hero who is very capable in editing, coloring and mastering). Only this time the lines between production phases are even more blurred. The artist will have to leave the comfortable settings of a studio and take part of pre-production and production itself.
Throughout filmmaking there have been different technicians on set to assist DoP. But it has never been unthinkable that DoP cannot take care of all the responsibilities on his own. For a short period of time it was color technician who was the exception to prove the rule. Now with the advent of digital film cameras and stereography once again technician have temporarily forced their way into mandatory part of the camera team.
There is a very principle reason why the technicians job fades away in time. DoP responsibility is to create the most memorable images anyone can imagine. Technicians job on the other hand is to make sure that the images do not stand out in any way. So for the sake of creative freedom DoP needs an artist as assistant rather than technician to tell what is not technically correct.
The tools
Most prosumer tools today are very capable of producing content for the highest cinematic standards. Then again I have not found one tool that would suite all the needs for post production, even the highest end tools need assistance. So we developed our own in-house software that would "glue" together all the different pieces.
Iridas Speedgrade and Metarender: very intuitive and easy to use grading software with support next to none. There is no special hardware requirements for full technical support. Command-line rendering is very important for integrating to in-house software. As an extra perk, one can easily drive cinema projector over SDI for final work in any Digital Cinema theater. Most importantly it will work with most of the media I get directly without any conversion or import procedure.
Iridas tools are central for our workflow, because it will be the first thing to decode any incoming material, prepare dpx files for compositing and effects and also the final step to finish grading, before rendering out J2C files for digital cinema masters.
I use one computer to run all processes parallel so I could make good use of multi CPU environment. So while 1 pass of metarender is preparing flat grade DPX files for compositing I am grading another part of the film. When DPX files are ready I will to the preparation for camera tracking, for computing time again I can grade next available shot. When processing finishes I will do the composite. All in supervised session.
The glue
The in-house software we use is built on similar notion of Batch in Autodesk products. The software keeps track where the sources are coming from and what procedures have been used on them, so if any compositing, grading, etc. changes are implemented, it will mark the downstream procedures for re-rendering and generates a script for rendering. As all the plugins for different parts are just scripts, it is quite simple and straight forward.
Extra to Iridas tools we use Cineform, FCP, Premiere Pro, Nuke, EasyDCP and Photoshop.
No compromise in quality
Thanks to these tools it is possible for one man to do the extremely technical finishing jobs in unprecedented quality and time frame. The other perk in working with DoP from very early on in the production I know from the first steps on where the film is going aesthetically, so even when picking a camera and lighting equipment DoP can make well informed choice.
When I am on set as second AC, DIT, Stereograopher (or all of the above), I can help to make sure that every step is in the right direction for the end goal. The final finishing becomes just executing the final details rather than trying to bang the footage into something it was never shot for.
