Flux.1 prompting and guidance guides

Posted on by

CyberJungle, the Youtube channel of Hamburg-based Senior IT Product Manager Cihan Unur, recently posted a great video on consistent generated characters.

There are lots of great insights in this 20-minute video. Two outstanding takeaways:

First: a prompting guide for Flux.1. At 15:28 he reveals three prompting styles: list, natural language and hybrid.

Second: a guidance guide for Flux.1. At 17:18 he shows Photorealistic and Cinematic images with a wide scope of guidance values. He posits:

“The essence of guidance setting is a compromise or a balance between photo realism and prompt understanding.”

See 18:36 for the Photorealistic results. He prefers a level of two.

See 19:54 for the Cinematic guidance level he prefers: again two.

My take: to me, too often generated images look over-the-top and so ideal, they’re unrealistic. The key seems to be dialing the guidance down to two. Who knew? Now, you do.

You can now star in generated video

Last week we explored the latest Generated Video (GV) pipeline. This week Seattle’s Yutao Han, aka Tao Prompts, goes further and illustrates How to Create Ai Videos of Yourself!

The goal here is to consistently end up with the same real person in multiple generated video clips.

“In this tutorial we’ll learn how to use the Flux image generator to train a custom AI model specifically for your own face and generate AI photos of yourself. Then we’ll animate those photos with the Kling AI video generator, which in my opinion generates the best AI videos right now.”

In a nutshell, the process is:

  1. Create an archive of at least ten photos of your star
  2. Upload this to the Ostris flux-dev-lora-trainer model on Replicate
  3. Train the LORA custom image model and use it to generate key frames
  4. Upscale these images on Magnific, optionally
  5. Generate six second clips in Kling AI with these images

My take: it seems week by week we’re getting closer to truly usable generated video that rivals (or even surpasses) Hollywood’s CGI/VFX. Imagine being able to train more than one LORA model into Flux for Kling. I have it on good authority that that is just around the corner.

New Generated Video pipeline?

A couple of very recent videos point to a potential new Generated Video, or GV, pipeline.

The first is “Create Cinematic Ai Videos with Kling Ai! – Ultra Realistic Results” by Seattle’s Yutao Han, aka Tao Prompts.

The second is “How-To Create Uncensored Images Of Anyone (Free)” by Lisbon’s Igor Pogany, aka The AI Advantage.

Imagine combining both into a new GV pipeline:

  1. Train custom character models
  2. Create key frames utilizing these custom models
  3. Animate clips with these key frames
  4. Upscale these clips
  5. Edit together.

My take: a lot of people will immediately claim this is heresy, and threatens the very foundations of cinema as we’ve come to know it over the last one hundred years. And they would be right. And yet, time marches on. I believe some variation of this is the future of ultra-low budget production. Very soon the quality will surpass the shoddy CGI that many multi-million dollar Hollywood productions have been foisting on us lately.

August 2024 AI Video Pipeline

Love it or hate it, as of August 2024, AI Video still has a long way to go.

In this video, AI Samson lays out the current AI Video Pipeline. Although there are a few fledgling story-building tools in development, full-featured “story mode” is not yet available in AI video generators. The current pipeline is:

  1. Create the first and last frames of your clips
  2. Animate the clips between these frames
  3. Create audio and lip-sync the clips
  4. Upscale the clips
  5. Create music and SFX
  6. Edit everything together offline.

It seems new platforms emerge weekly but AI Samson makes these recommendations:

00:23 AI Art Image Generators
09:19 AI Video Generators
16:28 Voice Generators
18:02 Music Generators
20:44 Lip-Syncing
21:52 Upscaling

Keep an eye open for LTX Studio though.

My take: You know, the current pipeline makes me think of an animation pipeline. It’s eerily similar to the Machinima pipeline I used to create films in the sandbox mode of the video game The Movies over ten years ago:

July 2024 Tier List for AI Video

Igor Pogany of The AI Advantage recently released a YouTube video that succinctly summarizes the current state of AI Video.

The tools he reviews are:

His favourites (dated mid-July 2024) are:

Runway GEN-3 Alpha and Luma Dream Machine for their clip outputs, but watch out for LTX Studio because of their overall project approach.

See the full tier list at 12:48 for the tl;dr.

My take: this is a super-valuable video that can get you up-to-date in under 14 minutes. Well worth your time.

Reality check: LTX Studio mid-2024

You’ve seen the Sora samples. The Dream Machine videos. How does LTX Studio, touted as “the future of storytelling, transforming imagination into reality,” stand up?

Haydn Rushworth posted this review:

“There are whole bunch of things it does not do, but I love where it’s going and where I hope it’s going to go…. It’s brilliant for keeping track of all of the shots that you really do need to keep track of. It’s brilliant for scene wide settings and project wide settings, something I’ve been craving, and it’s really, really good at that. It’s great for casting. It’s brilliant for allowing you to then kind of just drop those characters in. I love the generative tools that will allow you to erase bits that you don’t need in your starting shot and to add other bits that you need that will help you tidy up the shot…. My two big gripes and I don’t think these are bugs that they’re going to fix, this is just fundamental features that it needs to be in there. One of them is every shot is slow motion…. Secondly, breaking the fourth wall. It drives me out of my mind!”

Note that LTX Studio can do lots of things:

  • Pitch Decks
  • Storyboards
  • Animatics
  • Videos

Check out the video at the bottom of the corporate webpage.

Here’s a peek at actually using LTX Studio by Riley Brown:

My take: In addition to Haydn’s slo mo and fourth wall gripes, I would add these requirements as well: movement and expression control including blinking and lip-sync. Mid-2024, one has to use each of the many AI tools for what it does best and then bring all the bits together in post. As an early proponent of Machinima (using video games to make movies,) I’m watching this space with interest. My conclusion: advances are being made but we’re nowhere near lucid dreaming.

Apple Log Tips

Full Time Filmmaker on YouTube recently released “The Secret Formula for Cinematic iPhone Videos“.

In it he reveals the following:

  1. Record in ProRes Log on an iPhone 15 Pro at 4K 30. He says, “4K 24 especially at ProRes Log just looks kind of choppy.”
  2. In Settings, change to “Most Compatible” from “High Efficiency” and lock the white balance.
  3. Turn on Exposure Adjustment and set it to .7. He says, “If your highlights are blown out it’s going to be a lot harder to actually bring that detail back once you go into color grading.”
  4. Use the main 1X lens under adequate lighting, avoiding top-down noon sunlight. Try angling the light on the opposite side of the subject. He says, “The lighting is probably the most important element actually in making those cameras look good.”
  5. Use the Grid to help create interesting compositions and make sure your camera movement is motivated.
  6. In the edit, convert the Log footage with a Color Space Transform into Rec 709 and colour grade as usual.
  7. Use Halation to lend the footage the characteristic film highlights glow and use a plugin called RSMB to add motion blur.

An excellent video!

My take: Davinci Resolve 19 Studio has just come out with a Film Look Creator effect!

It seems like you’ll still want to add some motion blur, which you can do in Davinci Resolve:

The “middle” will disappear

The Rest Is Entertainment on Youtube recently released an episode with a take on How AI Will Take Over Hollywood In The Next 10 Years.

Hosts Marina Hyde and Richard Osman “pull back the curtain on television, film, journalism and more using their years of knowledge, enviable contact book and wit to bring what’s hot and what’s not in the world of entertainment.”

The episode has them reacting to the first Sora announcement and AI in general. This exchange is particularly insightful:

RO: “…that entire middle of the industry which is where everyone I’ve, you know, worked with my whole life works, you know, it’s going to be really, really tough times I think and there’s no safety net put in place but it’s the middle of culture that will disappear and be replaced by AI I suspect and it’s coming soon and it’ll come sooner.”

MH: “As always the middle in everything is going in the way that mid budget films have fallen away and that kind of middle bankable quality stuff has gone and at the moment I cannot see a pathway to it coming back.”

Richard also says:

“If you’re a new creator in the industry, if you’re a new brain (and by the way it’s quite hard to get into the industry) and you have these tools at your disposal, you would just be using them. I remember a very, very young Edgar Wright when he was starting out and him and his friends would just make these little home movies on videos because that was a new technology that they could suddenly use. If you’re a young person now, a young writer, young creator, young director, a young actor, why would you not be using these AI tools to make incredible content and sharing it with people?”

My take: These comments echo what Jerry Seinfeld recently said about the movie business in general being over. I foresee a continued splintering of audiences into smaller and smaller niches, necessitating smaller budgets as profits also become smaller. Every once in a while something will break through into the general Big C Culture but for the most part that will be left to deep-pocketed streamers chasing smaller and smaller mass audiences. As Seth Godin says:

Apple Log on iPhone is Not a Gimmick according to ZY Cheng of Malaysia.

In a fast-paced 10 minutes he covers:

  • the difference between conventional filming and filming in log
  • how exposure changes in log (1:12)
  • using the iPhone Camera App to film in log (5:06)
  • using the Blackmagic Camera App to film in log (5:47)
  • the log profile and black and white levels (6:31)
  • log exposure tips for day and night filming (7:53)

Apple Log is available on the iPhone 15 Pro and Pro Max. Note that Apple will most likely be upgrading these come September 2024.

My take: I want this. I need this!
