From an interview with Jean-Luc Godard’s cinematographer Fabrice Aragno in the current (January/February 2018) issue of Film Comment. Make of it what you will:
Q: Could you talk a bit more about what you do with the material JLG gives you—the edit he has made with his DVCAM recorder from what he plays on his TV.
A: You know how in postproduction you are supposed to color-correct the picture so everything is smooth and even? Jean-Luc wants the opposite. He wants the rupture. Color and then black and white, or different intensities of color. Or how in this film, sometimes you see the ratio of the frame change after the image begins. That happens when he records from his TV onto his old DVCAM analog machine, which is so old we can’t even find parts when it needs to be repaired. The TV takes time to recognize and adjust to the format on the DVD or the Blu-ray. Whether it’s 1:33 or 1:85. And one of the TVs he uses is slower than the other. He wants to keep all that. I could correct it, but he doesn’t want me to. See, here’s an image from War and Peace. [Shows sequence on his laptop] He did the overlays of color—red, white, and blue—using an old analog video effects machine. That’s why you have the blur. When I tried to redo it in digital, I couldn’t. The edges were too sharp. And why the image jitters—I don’t know how he did that. Playing with the cable maybe. Handmade. He wants to see that. It’s a gift from his old machine.
