When to remove noise, before, during or after editing?
After partially filming my first scene of the new short film I'm making, I a little disappointed by the amount of noise I had in some shots. I was thinking of using noise reduction software since HitFilm 2 Express doesn't have the noise reduction feature, but I don't really know what to do best, in combination with the MOV DNxHD format.
(By editing I also mean applying a grade which worsens the noise a bit)
-Should I convert the video to MOV DNxHD, reduce noise, and start editing?
-Should I reduce noise, convert to MOV DNxHD and start editing?
Or should I convert to MOV DNxHD, start editing, export the scene, reduce noise, import it into the project with the rest of the scenes later on?
My camera (Nikon D5200) has got an inbuilt noise reduction feature which I set to low/normal. There's some options for higher noise reduction too, but won't that affect the quality of the image in the end? I have no experience with this function.
What do I do to get the best looking image in the end?
