Samples render history

Is there some trick to view history sample progress render quality.
ex. Preparing animation and put low frame rate test render. Leave it for night and in the morning i can check every frame sample rate quality (maybe not every single sample - maybe every 5-10-20 sec render factor etc)
then i can evaluate scene sample setup for noise reduction/time

hi, no, so far nothing like this is octane. besides, noise reduction/time is different for different scenes. it's not going to be standard, depending on a myriad of factors, eg. lights, specular materials used, etc...

yes you are absolutely right. But i think it will be cool if we start test render and don't need to stair in render progress to see when and where the noise remaining.
Imagine you want render camera movement in interior scene where is different lighting on camera path. I can set render test whole animation but render only the every 30 frame and then go away - ex.for jogging ;-). Come back later and i can see how every 30th freme render engine reduce noise (in frame 1 lets see it handled nose with 1200 samples but in 30th frame engine need 1500 samples and 60th, 90 ....)
Also it will be easier to see how our changes in materials lights and render settings affect render - if we can "scroll back and forward" faster see render denoising (Its like recording picture/live viewer while it rendering)

I think it is not mutch problem to add option for renderer to dump progres fo every 10 seconds (adjustable amount timne or samples).
We can do this right now in picture viewer and live viewer - we can manualy save frame while it rendering and then compare it (see 40 minutes render in few second footage)

Hey!

i wonder if it would be possible to implement an optional Noise-Threshold linked with the max-sample value to stop the render like e.g. the antialiasing-Engine of Vray?
maybe the software could focus on the noise areas of the image while the areas which meets the threshold are not sampled anymore?

i am sure that the developers know much more about the technical issues than i do - but maybe it can be explained shortly why this does not work - i bet if it would work it would have been implemented.
