Do some calculations; you now have 1021 frames, but the video is way too fast, so you might end up with a lot more frames…
If one frame would take 3 minutes to render on your computer, that would mean about 48 hours of total render time with the current number of frames.
The ‘Classroom’ scene took an average of about 8 minutes to render (Blender Open Data), to give you an idea. (but that is on good computers, on my pc it takes about 90 minutes at 300 Samples.)
Denoising doesn’t perform optimal in ‘animations’.
Eevee will of course be a lot faster, but you lose some realism and it doesn’t support Displacement.
Personally I’d just render out a few shots each week and only make the whole video when finished, but that’s up to you.
