Character consistency in v6

- [Instructor] With Midjourney V6, a new parameter has just been released called Character Consistency. The idea is that you create a character with Midjourney, and then you use the link from the character that you created in other scenes so that you have consistency across your images. So let's start off by creating a character, then we'll use that character in other scenes and then decide how much that character has influence on our new image with another parameter called Character Weight. So we'll start off with the imagine prompt and let's type in, a medium shot of an Asian astronaut with her helmet off exploring an abandoned planet. We'll follow that with the aspect ratio parameter. So that's --ar16:9, and let's see what character Midjourney comes up with. Okay, while we didn't quite get her helmet off, we do have our character exploring an abandoned planet, and I just so happen to like the third shot down here. So I'm going to press U3. Now, the trick is to copy this link and then use that and a new parameter called character reference, which is --cref. So just right click the photo that you're currently using that you want to use and choose copy link. And now let's start with a new Imagine prompt and put this character in a brand new scene. In this case, I'll actually use a similar prompt like what we did last time. So I'll type in a medium shot of an Asian woman at a Paris Cafe in the 1970s, and let's just add some detail here. The look is desaturated and it's shot on a Hassleblad camera. We'll follow this with --ar16:9 to keep the aspect ratio that we've been using. And now for the new prompt, which is --cref, we'll now add a space and paste our prompt. So Command V or Control V, depending on which computer you're on. Now that that has been injected, let's press return and wait for Midjourney to come up with its results. Okay, here are the results produced of our character, now shot in the Paris Cafe, and let's compare that to the original character reference. What we can see here is the fact that our original character was an astronaut. Her uniform actually carries on over to the Paris Cafe, and this is where character weight can come into play, so that we can allow Midjourney to be a little bit more creative with how it places that character in the scene. So I have remix turned on from another movie, so you can actually turn this on if you'd like under your Midjourney preferences. So just simply go to settings, and if you bring up your settings, make sure Remix is enabled. I don't need to make that change right now, but what's going to happen is when I re-roll this exact same prompt, which has already my character reference, I'm now going to append something here at the end. Another parameter, which is --cw for character weight and character weight is on a scale of zero to 100. By default it's at 100, which means it's taking in the character as much as possible. Zero has a little bit more freedom in terms of creativity. I'm going to set a value of 25 in this instance. Let's press submit and see what we get. Okay, here are the new variations that Midjourney has come up with. And again, let's compare that to our original astronaut where you can see that in the new variations there is no astronaut uniform and there are some differences in her appearance. This could be great in defining how specifically we want it to follow that character reference. In this case, I like u1, so I'm going to up rise that and now use this as a new character reference combined with something we learned a few movies ago, which is style reference and style reference has recently been improved. So first off, I'm just going to copy one link here. So I'm going to right click and choose copy link. So this will be our character reference. Let's find a new imagine prompt, a wide shot of an Asian woman in ancient Rome. I'll follow this with --ar 16:9. And let's follow this with the character reference. So that's --cref, paste the link. I'm now going to add a space where we're going to add the style reference parameter --sref. And for a reference we used earlier of this grunge rock band that we've created. And this is also included in the exercise files. So you could upload this. I'm going to right click this, and choose copy link, and this will be our reference. Press return, and let's wait for the results. Okay, so here's our character in Ancient Rome, and we can see from this, this was the original reference that we had. And also let's consider the style reference that we just added all combined into one. As you can see, character consistency is a game changer when it comes to creating storyboards, ideating here in Midjourney and combine this with style reference and you have a very powerful workflow at your fingertips.
