You should start with a low number like a 100 and decie how this looks for you. Your goal with this setting is to find the perfect number for your case. Low amounts of samples will lead to a grainy image. Because the amount of samples defines how detailed and sharp everything will look. The most used thing here is the “ Max Samples”. So if you set it to 30 minutes – no matter what, the render will be done when it hits the 30 minutes mark. For example, you can set the maximum amount of time the render would take.
