Siggraph 2017

OpenVFX_siggraph2017_header_flat_01

I’m not sure if this was my 4th or 5th Siggraph. I’ve been attending the conference since I began using Blender professionally, invited by Ton to help work the booth and chat with people about using Blender for visual effects. Siggraph become one of the highlights of my year. I’ll be completely honest with you, though – I’m probably not the best person to write about Siggraph. I do not take full advantage of the convention. I don’t go to talks, don’t attend the parties, don’t get to visit every booth on the exhibit floor, and I don’t pick up a Pixar teapot. (more…)

Intro to Compositing in Natron

Finally, I’ve finished this up and I’m getting it out there! The first Natron tutorial for OpenVisualFX. If you haven’t heard of Natron, it’s an open source compositing program very similar to Nuke. In fact, it’s similar enough that if you know one, you know the other. I wanted to come up with a fun scene with some relatively standard compositing work, the kind of thing an artist at a professional studio is going to be doing all the time, and the TNT television show The Last Ship gave me the perfect opportunity.

Interview with David F. Sandberg

David F. Sandberg is a rare breed in Hollywood – a director who does his own visual effects. In fact, he’s a one-man film studio! Have a look at his Youtube channel and prepare for a crash course in filmmaking. Seriously, I’m not kidding. It’s some of the most inspirational behind-the-scenes clips I’ve ever seen. (more…)

Using Blender’s Vector Pass in Nuke

Wow. Sometimes you think something will be easy and automatic, and then reality steps in and yells “Nope!” right in your face. This is one of those common things a compositor runs into almost daily – using a vector pass from a 3D program to add motion blur in post. Using a vector pass speeds up the 3D rendering and lets the compositor make adjustments to the motion blur without having to re-render any 3D elements.

Creating a Matte Painted shot in Blender

OpenVFX_set_extend_header_flat_01

A few months ago, I was excited to once again contribute to 3DArtist magazine. This time I was asked to write a piece involving set extensions, which of course means matte painting. I hired an actress and headed right out to shoot something that could be open to lots of different creative interpretations! The printed article (and what was offered for download) was limited by space, but I thought it was a fun tutorial so I really wanted to go over all the details here on the blog and take it even further.

Blender – Stabilizer Improvements & Muzzle Flash

If you’ve tried to stabilize footage in Blender at any point since the inclusion of tracking tools during the production of Tears of Steel, you may have noticed a large, glaring omission – scale. Translation and rotation, no problem. But we have not been able to stabilize scale in Blender at all.

Smoothing Camera Motion in Blender

OpenVFX_highpass_header_flat_01

Handheld camera work is very common today, but if you’re out there shooting your own movies, sometimes you may find your footage has a high frequency shake that is just really annoying. I’ve found that the smaller the camera is, the more chance there is of introducing that jittery motion. With people shooting movies on smartphones and GoPros, cameras really can’t get much smaller! That means there is a lot of high frequency jitter in those handheld shots. (more…)
