Hi Lars
We can't see what media you were working with; we can't see its content and we can't see its codec, we can't see what you did with it and we can't see the settings you used to create the exported clips with the different data rates ... so consider everything that follows as a very broad response.
Your exported media's file size / data rate is determined by your export settings.
Specifically, your choice of codec (encoder/decoder) determines by what method your video data will be compressed. Your original file's compression settings produced a file that was 160,957 kbit/s... you imported that file and Resolve decompressed for editing /playback, so you could work with it. You did your thing, and then you exported your new clip ... the settings you used in this last step (the export) will not have been the exact same settings used to produce the original clip... and indeed it produced a file that was 96,654 kbit/s.
With respect to Neat Video affecting your end point file size / data rate, remember that the codec of your choice, regardless of that choice, is encoding all the video data it is given ie the good data (eg the nice picture) AND any bad data (eg any noise). By cleaning up the noise with Neat Video, you are potentially reducing the amount of bad data that needs to be encoded by replacing it with nice a clean/smooth picture that's much easier/more efficient to encode, thus the second export produced a file that was 18,769 kbit/s.
Your final step was to change the speed... and I'm assuming you mean you slowed it down, because less movement in the picture means less change from frame to frame, and less change from frame to frame can mean less data that needs to be used to encode those frame changes. Hence the data rate in your final result dropping to 12053 kbit/s.
Hope that helps you visualise what's happening.
