Not everyone has the same opinion as to what exactly is the “film look”. My suggestion would be to do some experimenting with the settings in the camera, 24 fps, etc. Also with filters, lighting, etc. I don’t think we’re talking about the movement of the film because the sprockets do not fit tightly enough in the sprocket holes of the film, or scratches, etc. (or are we?)
I was brought up in the “film world”, having spent about 20 years there before taking the leap into video. I worked in both 16mm and 35mm, and edited on Moviolas, as well as flatbed editing tables such as KEMs. Video has always been too clean and plastic looking for my taste, but that’s just me.
If you find a solution to your predicament, please let us know.
