What is a convolution? A beautiful explanation + visualisation

[ChaosKing]

The youtube channel 3Blue1Brown has just published video on this topic with a very nice visualisation:

It definitely helped me understand the convolution function. This is basically what convolution() does in avisynth / vapoursynth.

If you are impatient, start at minute ~8:00


There's also a video on Fourier transform :cool:

Yep, watched few video on this channel and I think it's quite amazing and so well presented.

Ah, Grant Sanderson, I know his channel, I would suggest everyone to watch the linear algebra series as it will help everyone understand the beauty behind it and behind lots of the things we use in encoding. Keep in mind that Grant is a mathematician who developed his own python library to create those visualisations and his scripts are always accurate.
