FFmpeg add a watermark to video

How to Add a Watermark to Video

FFMPEG filters provide a powerful way to programmatically enhance or alter videos, and it’s fairly simple to add a watermark to a video using the overlay filter. The easiest way to install ffmpeg is to download a pre-built binary for your specific platform. Then you don’t have to worry about including and installing all the right dependencies and codecs you will be using.

Once you have ffmpeg installed, adding a watermark is as easy as passing your existing source through an overlay filter like so:

ffmpeg -i test.mp4 -i watermark.png -filter_complex "overlay=10:10" test1.mp4

Basically, we’re passing in the original video, and an overlay image as inputs, then passing it through the filter, and saving the output as test1.mp4.

Realtime Fluid Simulation: Projection

Realtime Fluid Simulation: Projection

The core of most real-time fluid simulators, like the one in EmberGen, are based on the "Stable Fluids" algorithm by Jos Stam, which to my knowledge was first presented at SIGGRAPH '99. This is a post about one part of this algorithm that's often underestimated: Projection

MG4_F32.mp4

Stable Fluids

The Stable Fluids algorithm solves a subset of the famous "Navier Stokes equations", which describe how fluids interact and move. In particular, it typically solves what's called the "incompressible Euler equations", where viscous forces are often ignored.

Encoding to Hap from the command line using FFmpeg

Encoding to Hap from the command line using FFmpeg

For users who prefer working with a command line or need to access advanced encoding settings for Hap the popular FFmpeg library can be used to work with Hap movies.

  1. If this is your first time using FFmpeg you may need to install it on your system, or compile it from source. In either case be sure that Snappy is enabled as part of the binary. If you already have FFmpeg on your system with Snappy enabled, you can skip this step.

    You can check that your version of FFmpeg can encode Hap using

    ffmpeg -encoders | grep hap

Tech Art Expectations
There are a handful of different specializations under the ‘Tech Art’ umbrella, the first step would be to identify what area interests them. Below are different specializations and what skills I would expect for each discipline.
Technical Animator (TD at IG)
This role is for an individual interested in empowering Animators. Physics, jiggle, muscle deformation and cloth simulation are particular areas that would be explored in this role. A portfolio would show the following:
• Understanding of Rigging
• Understanding of OpenMaya/PyMEL/MEL/Python
• Understanding of Mocap Pipelines
