  <p>Judging by the image you provided, I would try Despeckle first, then add perhaps a very very small gaussian blur (very small like 0.1 or 0.2), then last, ADD noise to the image, use a very low variable, like 2 or 3, and use monochromatic noise (no color). Adding noise, a very small amount, will add a bit of texture to the image, much like film grain, and help mask out any little specks which might have been missed by the previous effects. </p>
  
  <p>Again:  Despeckle -> Gaussian Blur 0.2ish -> Add Noise No Color Checked setting in the 2-4 range (setting may need to be higher if your image size is large, say 4k). </p>
  
  <p>Record that, then process. </p>
  
  <p>Take your TIF sequence processed through photoshop. Drag into PremierePro.  Set Still frame length to 1 Frame. </p>
  
  <p>Create new sequence from 1 of the frames to match frame settings. Drage all your images to sequence. Render out as whatever you want. Then take back into AE if need be. </p>

  As an alternative to the denoising method suggested by @CoinRocket, you could try to export the scene from Blender with less noise. If you have enough computation capacity, this will be a superior solution since post-denoising will always introduce some amount of blurriness into your video.
  
  The noise in your example image looks like [fireflies](https://en.wikibooks.org/wiki/Blender_3D:_Noob_to_Pro/Advanced_Tutorials/Cycles_Fireflies), i.e. artifacts that stem from the nature of the [Cycles Engine](https://www.blender.org/manual/render/cycles/introduction.html) in Blender which is based on ray-tracing. There are several ways to reduce fireflies, however depending on your settings and available hardware render times will become *extremely* long. A while ago, I exported a 15-second sequence at 1000 samples and 24 frames per second rendered for three days straight on my laptop. So be warned.
  
  The easiest way to reduce fireflies is to [increase the number of samples](https://blender.stackexchange.com/questions/4980/how-to-avoid-noisy-renders-in-cycles) the program runs during export. This will correlate directly with rendering times.
