Vitamin C Serum animation

Long slow drip simulation made in Blender.

Vegetation is almost impossible to render out without noise and flicker, unless you up the sample count to unreasonable amounts. You probably know that "blender flicker" with vegetation, that comes from the Blender internal denoiser denoising frame by frame and not looking at multiple frames at once. The workflow is: final render without Blender denoise > 750 samples > multi image Neat Denoiser on the final animation in after effects > Topaz Labs AI denoise > Lumetri Color sharpening in after effects. A LOT of processing and still far from perfect, but at least with this workflow the flicker is not that visible anymore. I think that's the worst. You can get a less pronounced flicker by not utilizing the translucency channel for the vegetation, but then it will look incredibly fake, which is not ideal either.
