Hi, generally Corona's render settings are optimal by default, you don't have to change them. You can change two values to get slightly faster rendering at the cost of realism (your image will become darker):
- Max sample intensity - lower as much as possible without making your image appear too dark (at some point it will just turn off indirect lighting)
- Max ray depth - lower as much as possible (this will also make rendering darker and will lower the number of reflections, for example visible in mirrors)
The most important part when rendering animations (and it can also save some render time) is setting up the UHD Cache correctly. See:

https://support.chaos.com/hc/en-us/articles/4528588388113You can also save the rendered frames with denoising and without denoising at the same time. Add a CShading_Beauty render element and then you can disabled denoising in that render element and enable it for the image rendered in the VFB. This way you will get the same image with and without denoising nad you can decide which ones to use, or blend between them.
