Show HN: Movie Iris - Visualizing Films Through Color Extraction

#1
I saw someone post these on reddit 4 years ago, and I really wanted to make them. I was surprised they didn't open source their code, so I rebuilt it.

Lots of things I would do differently now haha, but anyway, figured someone here might find it interesting.

This is quite nice. Not sure what the meaning is of a circle versus, say, a linear strip, but it’s very effective for showing the dominant colors over time. I’d love to generally see this for many movies across time; my understanding is most are color graded green/yellow now and it’d be nice to visually see this evolution.

This post brings back memories. I remember watching this trilogy in an old movie theater that still showed film, and it was amazing experiance.

"Red," "White," and "Blue" is a trilogy of French films made by Polish-born filmmaker Krzysztof Kieslowski. Each movie follows the color pallet.

Modern digital movies are way too sharp, in a bad way.

I have a cli tool I maintain that finds visually similar images.

As a fun experiment several years ago I extracted all the frames of Skyfall and all the frames of the first Harry Potter movie.

I then reconstructed Harry Potter frame by frame using the corresponding frame from Skyfall that was most visually similar.

The end result was far more indecipherable than I'd ever expected. The much darker color pallet of Harry Potter lead to the final result largely using frames from a single dark scene in Skyfall, with single frames often being used over and over. It was pretty disappointing given it took hours and hours to process.

Thinking about it now, there's probably a way to compensate for this. Some sort of overall pallette compensation.

I'm interested in this. What's your similarity measure? I was going to write a frame comparison tool to make seamlessly looping video.

If you had a much bigger corpus, and used some semantics-aware similarity metrics (think embeddings), you could maybe end up with something actually coherent
