Many movies are still shot on films. At the same time, computers can greatly facilitate editing. So I just wonder how the whole process is done. Is film digitized and edited on computers or is it literally cut and edited like in old good times?
I can answer this as least as far back as Star Wars Episode VII. The movie was shot on film, and the film was digitized as reels were filled up (they didn't save it all and wait until all of filming was finished) then the film rolls were treated and archived to help preserve them. From there on out, all editing and work was done digitally.
If one was lucky to ever tour Lucasfilm in San Francisco, you would find lots of old film editing equipment on display in the hallways -- they don't use it anymore.
