Error writing TIFF

Does anyone know why this might be happening – for some unknown reason to me, Nuke just won’t write a TIF / TIFF file and is chucking out the error:
write error at scanline 2303

Usual things have been checked like I do have permissions to write to that directory, other formats work fine (JPG, EXR) it’s not a Proxy output etc. etc…. tried all different compression types…
Also tried with Nuke 5.1v5 64 bit and 32 bit but both give the error.

Why the problem?

It’s a real pain in the arse to chuck out an EXR and convert it to TIF in Photoshop….

Thanks in advance if anyone can shed any light

Can’t smooth a track?

Came across a little snag here while doing some paint work. I did a track on this plate so I could matchmove in the fixes, but the rotation of the track is a little jittery. I wanted to smooth out those points in the track node, but it wont let me! I can’t figure it out. i’ve selected the specific area of the track in the graph editor, hit smooth from the right-click menu, but nothing is applied… Am I missing something here?

making a button in Nuke

Hey

I’ve seen it done in Nuke where instead of having a list of nodes or scripts under a menu on the toolbar you have a button which just has one purpose – to evaluate a script.

I’m familiar with making custom menus for Nuke but I would quite like to have a button for a script I’m writing.

Does anyone know how to write this in python? Any help would be greatly appreciated.

Camera export from 3D Studio Max into Nuke

I´m a Maya user but because of a recent project i´m using Max.
I´m having some problems in exporting the camera from Max to Nuke. I use the same process like in Maya: Export all through .fbx and in Nuke i make a camera read from a file, the same .fbx but nothing happens.
Is there any specification that i´m missing?
Hope someone can help me.
Thanks
Cheers

Vfx cuts may affect upcoming films

Economy hits high-end visuals, studios concerned

By DAVID S. COHEN

Visual effects now vie with stars as box office draws in summer tentpoles. But a possible shortage of visual effects shops could be a brutal blow to the next wave of f/x-heavy tentpoles.

Studios depend on outside vfx shops to deliver ever-larger amounts of first-class work on ever-shorter schedules. Some leaders of the visual effects business, both at vfx shops and at studios, are warning there could be a shortage of vfx capacity within a year — a shortage that could drive up costs and even threaten release dates.

The combination of Hollywood’s production slowdown and the recession have already driven some California vfx shops out of business, with more threatening to shutter.

Warner Bros. exec VP of digital production, animation and visual effects Chris de Faria says his studio is taking the threat so seriously, "We’re looking at advancing R&D and development work on projects, and the corresponding cash flow, to make sure that some of our valued vendors can get through this time," he says.

Here’s the dire scenario: As pics now in production wrap, vfx work slumps, killing off more midsized and small vfx companies. Then a new wave of tentpoles arrive, wanting more and bigger vfx, only to find insufficient capacity to complete them at the breakneck pace — and with the sometimes huge last-minute additions and changes — the majors now favor.

When this scenario may play out is the subject of some debate. Some expect the crunch to come late this year. Recently, though, tentpoles including Warner’s "Green Lantern" and Marvel’s "Thor" have been pushed back. That could push the potential crisis back to 2010 but may actually make things worse, as it means the lull would last longer.

"The studios need to be concerned about this," says Industrial Light & Magic exec producer for marketing Gretchen Libby. "Their options could start to run out for finishing their projects. There could be fewer companies that can help out at the 11th hour."

Underlying this warning is the fact that vfx shops are under financial pressure from several directions.

They were hurt by the prolonged slowdown after the WGA strike and prolonged SAG talks, then hurt more when production financing dried up, exacerbating the slowdown.

Even in the best of times, feature vfx aren’t lucrative for the companies that make them despite their importance and the typical tentpole’s huge f/x budget. As de Faria notes, "The feature film business, for most vendors, can be a boom or bust business. It’s glamorous, and it’s work done at the highest level, but it’s hard to survive just on that."

Many shops rely on commercials to provide an extra revenue stream. The recession, however, sent commercials production off a cliff.

Jeff Barnes, co-founder and executive producer of CafeFX, has been warning of a crunch for some time, as he sees some of his competitors, such as the Orphanage, shutter for good.

His own company dropped benefits and cut costs to stay afloat, and he warns that other vfx shops will need to restructure as well. In the short term, says de Faria, "The question I have is not where am I going to get the work done; it’s where am I going to get the high-level work done — the ground-breaking work that can be the center of a marketing campaign."

Many companies can do low-end work, with more springing up all the time worldwide. There is also no shortage of companies that the studios trust to do a modest amount of high-end work. French shop Buf and Germany’s Pixmondo fall in that category.

There are only about a dozen companies in the world that can handle the large number of shots with digital characters and other complex effects in today’s tentpole pics — the kind of work that concerns de Faria.

London, which has become a world center of vfx due to favorable exchange rates and tax incentives, is booked solid for at least a year, according to multiple sources. Projects looking to save money on vfx no longer have that option.

Universal, for example, is looking for cost savings on the vidgame-based actioner "Bioshock." It might have gone to London but the project is now on hold.

Marvel has "Iron Man 2" in production now and three big vfx tentpoles on its slate for the next few years: "Thor," "Captain America" and "The Avengers." They could be affected should capacity get tight, but Victoria Alonso, exec VP of visual effects for Marvel Studios, is confident that, even after a contraction, the vfx industry can bounce back to meet the challenge.

"If you have a company that’s shrunk, that means they will find it internally to grow again," she says. "I’ve seen that happen at every facility I’ve worked with."

Barnes agrees that shops have no choice now but to expand and contract, but he and others counter that rapid expansion can lead to quality control problems, as people who have never work together adjust to a new company while trying to meet tight deadlines.

Alonso says another solution lies in finding smaller companies anywhere in the world that have a specific skill set, then putting them to work on a contained sequence that uses those skills. The Embassy, she says, had done robots on a short film, so it got the job of doing the "Mark I" suit for Iron Man.

Ironically, when the next big wave of work arrives, vfx companies that are still standing stand to do well. There will be lots of work, and simple supply and demand could lead to higher-than-usual margins for long-suffering feature vfx companies.

"We might get a fair rate for the work for a change," says Barnes. More than one option

Harrison Ellenshaw interview

An old TV interview with visual effects supervisor Harrison Ellenshaw, who talks about TRON and where computer graphics is headed.

The Senate Visual Effects Build Pantheon for Angels and Demons

Following their exceptional work on The Da Vinci Code, Visual Effects Supervisor Angus Bickerton returned to The Senate Visual Effects to create a number of sequences for the follow up thriller Angels and Demons. The Senate worked on 196 shots and contributed outstanding environments and digital FX in several major scenes, most notably a photo real recreation of one of the largest and oldest churches in Rome, The Pantheon.

When Tom Hanks, as Robert Langdon visits Rome searching for clues to the Illuminati’s next victim, his path leads him to the two thousand year old building in the heart of the city. Unable to film on Vatican property the production built a partial set of the Pantheon interior that consisted of just two chapels and one altar surrounded by green screen. The Senate were then tasked with recreating the remainder of this iconic structure which stretches 140 feet in diameter and 140 feet in height and comprises a further five chapels, seven altars, intricate marble flooring and the great domed ceiling with its nine metre hole at the apex, the oculus.

Work began in June 2008 with The Senate designing previs for the entire sequence and building a CG scale model of the Pantheon. Senate VFX Supervisor, Richard Higham notes "After reading the script, it was clear that at this point in the film the Vatican authorities did not yet trust Langdon, so we wanted to create a scene that visually reflected this. Langdon and Vittoria enter the Pantheon uncertain of whether they were in the presence of the murderer, so we devised angles that felt nervous and dramatic and offered this to Angus as a complete animating 3D storyboard." By creating a CG model at this early stage they were not only able to establish the size of the ancient church and the prominence of the oculus but could also orientate the director and actors to where in the building the action was taking place when they were filming on the minimal set against green. The production responded well to the previs and some key shots in the final edit match it very well.

Richard then travelled to Rome to study the Pantheon interior. Because of the restrictions imposed on the production by the Vatican Richard had to masquerade as a ‘keen’ tourist and took hundreds of photographs to provide the team back in London with all the reference and high quality texturing photography necessary. Before the final model was complete, Richard and CG Supervisor Dan Canfora also attended the shoot on set in LA to ensure any technical problems were solved and that new ideas could be incorporated. Using the supplied rushes, the team then created temps of the entire sequence within a couple of weeks of the shoot. This enabled the production’s editors to explore the space and eventually led to a couple of extra full CG shots being added to the sequence, making maximum use of the meticulously built CG Pantheon.
Armed with the high resolution photography and a library of reference books, The Senate’s team spent over six months crafting the interior in Maya. One challenging aspect of the CG build was the lighting, which needed to be true to both how the set was lit and the intense natural daylight that beams through the oculus in situ. As Dan Canfora explains “The mood of the lighting was taken from a mixture of the on set lighting and the overall feel of the real Pantheon at that time of day. We used HDR images taken on the set to form the basis of the lighting, which made sure that all our set extension immediately sat together with the real set. Using Mental Rays image based lighting tools the HDRIs were used to bake the lighting into a point cloud allowing every shot to have its basic lighting colours, intensities, bounce and bleed. From this point each shot was honed to convey the correct lighting mood, be it deep shadows or the blaring sunlight coming through the oculus or the giant bronze doors.”

In addition to the intensely detailed structural architecture of the church, the team also had to build the many intricate objects that adorn the Pantheon. Using 3D modelling software Modo and Mudbox, they faithfully recreated items such as elaborate ten foot tall statues and ornate grand altars which then sit seamlessly in the environment. To complete the work, two further elements shoots were held, one at Sony Studios, LA and the other a motion control shoot at Twickenham Film studios, London, to capture extras to fill out the Pantheon with tourists. Look closely and you may be able to spot one or two of The Senate’s team amongst the crowd. In order to give the compositors control over every aspect of the shot, each one was rendered with up to 25 separate passes in Mental Ray. This allowed the compositors, using Shake to adjust the look as required, for example enhancing parts of the scene by boosting specular kicks and highlights, deepening shadows to create a greater sense of depth and adding extra reflectivity to the marble flooring.

Another ancient church The Senate worked extensively on was Di Santa Maria Del Popolo, situated in Piazza Del Popolo, which is the focus of Langdon’s search in a later scene. Here, once again permissions to film were restricted so The Senate were charged with modifying the exterior of the opposite building, a police station, to look like the church from the outside. Initially, this sequence began as 2D and 3D projection based matte paintings of the tower and Dome that adorned the real church and assembling them to the police station. Once the sequence reached editorial, new requests for complete sky replacements and POV shots of a distant St Peters were introduced to manage continuity and sequence consistency. Digital stills were once again used for these shots, taken at particular times of day to ensure the sun was in the correct location of the frame and casting shadows to match the film plates.

The Senate also created a unique look for when Langdon and Chartrand find themselves locked in the Vatican archives with the air supply cut off and they are slowly starved of oxygen. The brief for this sequence was to design an effect that depicted the visual degradation caused by hypoxia (oxygen starvation) for which Second Unit Director Todd Hallowell was able to provide a vivid description based on his and Ron Howard’s experiences of working with Nasa on Apollo 13. Working closely with Angus and Todd, The Senate tested various looks based on these descriptions and Senior Artist Anton Yuri came up with the final solution, a contra-zoom type effect. Richard explains. "This is where the camera physically moves towards or away from its area of focus. This is then stabilized within the comp on a central location leaving the peripheral edges of frame to warp and stretch giving an unnatural and unnerving perspective." Richard worked closely with Todd and the crew on the shoot, “for these particular shots, Todd was great and allowed me some freedom to instruct the cameraman to move in a way that would facilitate this effect to the max. The set space itself was a little bit limited so I requested wider angle lenses to help. After this, Angus asked for further embellishments so we added extra radial blurs that were isolated to the most luminous areas of the action." Vignetting was also added to enhance the tunnel vision and The Senate completed the rest of this scene tracking in bullet hits and cracks and enhancing the smashing glass with a dynamic particles system.

Other shots contributed by The Senate throughout the film include CG and matte painting set extensions, green screen composites, muzzle flashes and sky replacements.

The Senate Visual Effects is one of London’s leading boutique visual effects facilities, specializing in digital environments and invisible effects. They have previously worked with Ron Howard on both The Da Vinci Code and Frost/Nixon and other recently completed projects include Richard Loncraine’s My One and Only, Shanghai and latest Julian Fellows film, From Time to Time.
