I'm working on an animation for the sword I made for my Elf character. But in the close-up renders, there is some jitter in the texture, especially in the blurred areas. I wonder what would be my best option to fix this.
A) raising the sample count? (it's now at 540, for a 4K frame), on my MBP M2, that takes about an average of 7 minutes/frame.
B) Baking the texture to an image texture, but what resolution would you advise? Now the texture is procedural, but the model is UV unwrapped since I painted some maps in texture paint. Since it's pretty close-up to the model, I don't know if this is an option.

HI Jonatan,
I don't notice any jitter, to be honest. Maybe it's 'hidden' through the compression, or maybe you've been staring at it for too long...
But anyway, what could be causing it, is Adaptive Sampling, if you're using that. In that case, you should disable the Noise Threshold and see if that helps.
Thank you for your swift reply. In my ProRes, it is definitely more pronounced. And staring at it for too long is something that might be a professional deformation from my day job as a video editor. But I'll try disabling the Noise Threshold and see if that helps. What does that Noise Threshold do exactly?
Noise Threshold means that when the difference per Pixel between 2 consecutive Samples is less than the threshold, Blender stops Rendering that Pixel. So some Pixels get less Samples than others, This is great for still images, but can cause issues in animations. Just as Denoising can cause problems in animations, although there are Denoisers, that actually take that into account; this is usually referred to as Temporal Denoiser.
