The Django Unchained helmer re-affirmed his desire to stop making films "deep into my old age", saying that he dislikes digital projection and the idea of shooting with digital cameras.
In a roundtable directors' interview with The Hollywood Reporter, Tarantino lamented the loss of the traditional celluloid filmmaking process.
"Part of the reason I'm feeling [like retiring] is, I can't stand all this digital stuff. This is not what I signed up for," he said.
"Even the fact that digital presentation is the way it is right now - I mean, it's television in public, it's just television in public. That's how I feel about it. I came into this for film."
He continued: "I hate that stuff. I shoot film. But to me, even digital projection is - it's over, as far as I'm concerned. It's over."
Use of traditional 35mm print projection is expected to cease in the US by the end of 2013, with a "global cutoff" likely to happen at the close of 2015.
Tarantino added that the industry's shift to digital has led to him thinking about adapting one of his lengthy scripts for TV.
"If I'm gonna do TV in public, I'd rather just write one of my big scripts and do it as a miniseries for HBO, and then I don't have the time pressure that I'm always under, and I get to actually use all the script," he explained.
"I always write these huge scripts that I have to kind of - my scripts aren't like blueprints. They're not novels, but they're novels written with script format. And so I'm adapting the script into a movie every day.
"The one movie that I was actually able to use everything - where you actually have the entire breadth of what I spent a year writing - was the two Kill Bill movies because it's two movies. So if I'm gonna do another big epic thing again, it'll probably be like a 6-hour miniseries or something."
Tarantino has shot all of his films on 35mm, but experimented with digital when he guest-directed a scene in Robert Rodriguez's Sin City.
The Oscar-winning Pulp Fiction director said of his post-filmmaking plans: "I'll probably just be a writer, or I'll just write novels, and I'll write film literature and film books and subtextual film criticism, things like that."
His eighth feature Django Unchained opens in US cinemas on December 25 and January 18 in the UK.
