Wanted to find out the difference in using larger or smaller samples per pixel in terms of quality and time. I've also noted for each render how long it would take approximately to render the final sequence - being 600 frames - with these settings. Despite the visual differences not being obvious on the compressed versions here, of the outcomes I have decided to set my sample rate to Min:1, Max:4. Here are the results:
Up to 1/4 Samples per Pixel
0:21 min per frame render time
(approx 3.5 hours total)
1 Samples per Pixel
1:08 min per frame render time
(approx 11.33* hr total)
4 Samples per Pixel
4:09 min per frame render time
(approx 41.5 hours total)
16 Samples per Pixel
16:26 min per frame render time
(approx 164.33* hours total)
64 Samples per Pixel
1:04:12 hr per frame render time
(approx 642 hours total)
