zapIn this week's fxpodcast we discuss linear workflow. We geek out with 3D guru Master Zap of Mental Images about linear compositing workflow: separating fact from fiction, and discuss just how viable it is to set up a correct linear pipeline.

Why is linear compositing valuable?

Feature film compositing is nearly always 'linear' ironically - given the files are normally log ( ! ) but in the world of video and HD often multipass compositing and compositing is often done incorrectly leading to a series of hacks, fudges, and workarounds to make images look right.  Zap and Mike discuss the issue and flag ways to set up a correct pipeline.

  2. Thanks for the very informative discussion. I been researching a lot about this issue ever since I saw Stu’s post sometime back last year. Though I haven’t been able to put this into practice at where I work because of the common scenarios mentioned in this discussion.

    Anyway here are few couple of links which I found very interesting and helped me to get my head around this issue.

  3. Can we call this linear workspace “gamma 1”? I think it sounds cool and futuristic and it avoids the confusion of linear vs non-linear editing and people calling gamma 2.2 linear. Since non-linear editing has become common place I think the word linear has gotten a negative connotation.
