  <p>To do it justice it needs some film grain, and some softness. PP doesn't have a built-in grain effect, and its noise effect is pretty feeble. I added about 7% noise and a 5.6 px gaussian blur.

Answers.Text: Yes, Scopes show you what is going on with the colour in an objective way. Human colour perception is so easily fooled that it's hard sometimes to judge colour effectively. This is fine if you're just after a look, but when you're trying to match colour between shots they're essential.

Body: <p><strong>Summary</strong></p>
  <p>I'm making an artwork and here's how it goes in a nutshell: A fictional movie scene that was (1) shot on film in the '60s, (2) restored in VHS format in the '80s or '90s, and (3) restored again in a digital format in the present day.</p>
  <p>Now, from that second bit onward, here's how I assumed it went in practical terms: In the '80s or '90s, the movie (my artwork) was restored in a VHS format (with PAL standard) by a telecine machine using the release print. At the present day, the tape was restored in a digital format by an RCA-to-USB converter that connects the VCR to a computer.</p>
  <p>In order to simplistically replicate this process, I've been trying to split my material up into 3 separate YUV channels and work from there intuitively, since I believe it's the luma and chroma signals that make up this analog video effect, before the video gets automatically decoded back into RGB (correct me if I'm wrong).

I'm not trying to be perfect, I'm only finding ways to separate the channels and work from there intuitively, since I believe that would do the heavy lifting to get the effect.
