Frame Sequence Viewers


Visual effects artists work in frames sequences. That’s what we expect to get from the client, and it’s what we give back to them. EXRs, DPXs, PNGs, TIFs, even TGAs and JPGs. Compressed movies are for reviewing, but our main means of delivery on feature films are frame sequences. Independent projects can have a variety of different formats for delivery, but even then, it’s recommended that you work from frame sequences and just create the delivery movie from the final frame sequence at the end.

Blender screen replacement & marker removal

Lately I’ve been doing more and more for 3DArtist magazine. I got to meet editor Steve Holmes at Siggraph last year, and since then, he keeps inviting me back to do more fun compositing tutorials in Blender, which of course is a pleasure.

This is one I did for them in Issue 88. I wanted to introduce people to the idea that Blender isn’t only a 3D program, but could be used in place of Nuke or After Effects for most compositing tasks. One of the simplest and most common jobs is replacing a screen on a device. Monitors, phones, tablets, televisions, this technique works for any of those. It also works for anything flat in general, like billboards, walls, floors, replacing book covers, photographs, etc.


Welcome to OpenVisual FX!

Hello and welcome to OpenVisual FX! My name is Sean Kennedy, and this is my new blog and training site for professional visual effects using Free & Open-Source software (FOSS).

I’ll keep this intro nice and short. I’m a professional compositor and vfx artist and have been working on feature films, television, and independent projects in various effects positions since 1997. If you’re interested in exactly what projects, you can see my IMDB page here. For a few years now, I’ve been very interested in Free & Open-Source Software (FOSS), and I use these free programs both at my full-time studio jobs and when I do freelance work from home.

This blog is my outlet to share what I’ve learned. (more…)
