I was thinking about the behaviour of the unbiased rendering engine in an animation in whom there are both indoor and outdoor environments.

A simple scene: there's a camera that run across an open environment, then it enters in a windows, go along the room and it passes across the opposite window, then it returns outside.
I set render time to 20 mins(for example), then start the animation rendering.
The question is the following: It will be a quality difference between outdoor and indoor frames? Indoor scenes require more time to reach a reasonable quality, so if 20 mins are enough for outdoor scenes, it's not the same for closed environment, so when I will play the animation I will see a lot on noise in indoor part. Would it be a good idea to raise the rendering time? But I think that acting like that there will be a waste of time on outdoor frames, and basically there will be always the same problem. I don't know if there was a similiar topic before, somewhere in this huge forum, or it is yet a trick to avoid this problem yet. So if nobody never faced thif problem, maybe i can suggest you to add a feature (in animation) where you can assign render time in various group of frames in order to avoid this problem. (maybe this was a "wish list" topic)
Thanks for the patience reading this and sorry for the awful english!

Yea, the quality will vary if you use a time limit. Set the time limit really high (like a week) and set a sampling level target instead. Just do some test renders and find out what sampling level works for your quality level and time budget.

Have fun!!
