how are VFX added to movies shot on film?

704 views

I’m not really sure how the shoot a movie on film then proceed to edit it / add visual effects and then release it.

Digitally, for unprofessional people like me, we just take out the SD card, plug it into the computer, import the file into the software, do whatever then render it.

When its shot on film, I don’t get how they do all of that

You scan the film, so that you have an image of each frame. Then you compute your VFX to line up with the pixels in the frames. Then you print your VFX onto film. Then you can use multi-frame printing to get film for the scene. Or you do the composition digitally and print new frames.

Depends actually.

In modern times? Very few movies are shot of “film” these days so the editor pops out the SD card and loads it into their computer(ok, not literally, modern movies take up multiple terabyte hard drives per day of shooting because of the high resolution.

When we were first starting to do computer effects? They would scan the film in.

Further back when they didn’t have computers and needed to add effects after the fact? They would literally paint(with actual paint) the effects frame by frame.
