This is a collection of Pure Data patches to convert between timecode/frames, calculate shot duration, and roughly estimate job time on a render farm.
I created these tools to simplify my workflow when creating 3D animation scenes in Maya and After Effects. So these tools use a frame rate of 30fps for their conversions. But the patches can be edited to work at other frame rates, should you need.
It's free and open source. Available for Mac, Windows, & Linux.

Especially useful when adjusting timings between two versions of the animatic and need to figure out the exact amount of time added or removed.
Most useful for estimating the min/max time until the render is complete. Which is especially important if you’re worried about bottlenecking your farm and need to prioritize for deadlines.
