I've made a simple animation in blender 2.81a and am now trying to render it.
My system specs: CPU i7-6500U; GPU Nvidia Geforce GTX 950M; RAM 16gb DDR4 So far, I've done two test renders (both in cycles):
8 samples, 8 light bounces, denoising on, 60fps (240 frames). Total render time was about 3 hours. Looking at single frames, they were flawless, but if you play the animation, you see that the denoiser is producing some kind of jitter (like in this video).
256 samples, 4 light bounces, denoising on. I set the framerate to 24fps and used time remapping to maintain animation speed (96 frames). The jitter has become far less, but is still there. However, the time remapping made the animation look kind of not-fluent. So I figured that I probably need 512 samples to reduce the jitter and render at 60fps. However, this will probably take about 16 hours to render. Are there any other ways to
- change the framerate without changing the animation speed? (except for manually repositioning keyframes)
- decrease general render time/reduce the jitter (aka denoising for animations) Thanks in advance!
Edit: I heard that Blender 2.83 and 2.90 (which is not yet oficially released) have improved the denoising system, e.g. AI-accellerated denoise, adaptive sampling and optix viewport denoising. Do any of these also apply to video or is there now any option for better denoising for animations?
