SSTV in Max

Slow scan television simulation using Jitter.

See this Cycling 74 forum post for an explanation of how frame rate is limited by audio sample rate and  horizontal resolution: https://cycling74.com/forums/topic/jit-poke-vertical-bars-at-high-scan-frequencies/

Patches:

  • raster-scan4.maxpat (original)
  • raster-scan5.maxpat (better frame rate by lowering screen resolution to 160 x 120)
  • raster-poly-wrap5.maxpat (even better frame rate – up to 15 fps – by up sampling to 384 KHz)

Note – set your audio sample rate to 96KHz if possible, to get the results described above.

“It’s basically a vertex shader, so can’t be used as a pixelshader in vvvv, but could be used as a vertex shader in vvvv. You would have to convert the code from GLSL to HLSL though. The GLSL code is on my site (link above), but actually if you need HLSL you can find loads of similar radial distortion samples on the web (Alex has links to a few more superior radial deformations on his blog, again link above).

In this video the GLSL is simply deforming the sphere and rendering with a very basic flat shading, it’s VDMX which is doing the audio analysis and animating the parameters of the GLSL shader… and taking the flat rendered sphere and applying quite a bit of post effects to get this look.”
