I improved my workflow for contact sheet prompting using Nano Banana Pro. All the prompts, workflow files, and tips below. These are focused on 'fashion style' shoots, but can be adapted to any I2V workflow.

I have been building a free/open node editor for Nano Banana, I used it for this video. The JPow and Tim contact sheet workflows are in the examples directory, just drag and drop. It's a work in progress, but is available here:

Since this video is intentionally very similar to the Tim Apple one, I only a single to the contact sheet prompt. "Perfectly replicate the exact facial features of the model". It made a big difference for character consistency in the contact sheets. Here's the full prompt: -- Analyze the input image and silently inventory all fashion-critical details: the subject(s), exact wardrobe pieces, materials, colors, textures, accessories, hair, makeup, body proportions, environment, set geometry, light direction, and shadow quality. All wardrobe, styling, hair, makeup, lighting, environment, and color grade must remain 100% unchanged across all frames. Do not add or remove anything. Do not reinterpret materials or colors. Do not output any reasoning. Perfectly replicate the exact facial features of the model. Your visible output must be: One 2×3 contact sheet image (6 frames). Each frame must represent a resting point after a dramatic camera move — only describe the final camera position and what the subject is doing, never the motion itself. The six frames must be spatially dynamic, non-linear, and visually distinct, avoiding any progression such as wide → mid → close. Required 6-Frame Shot List (All Resting Frames) 1. High-Fashion Beauty Portrait (Close, Editorial, Intimate)Camera positioned very close to the subject’s face, slightly above or slightly below eye level, using an elegant offset angle that enhances bone structure and highlights key wardrobe elements near the neckline. Shallow depth of field, flawless texture rendering, and a sculptural fashion-forward composition. 2. High-Angle Three-Quarter FrameCamera positioned overhead but off-center, capturing the subject from a diagonal downward angle. This frame should create strong shape abstraction and reveal wardrobe details from above. 3. Low-Angle Oblique Full-Body FrameCamera positioned low to the ground and angled obliquely toward the subject. This elongates the silhouette, emphasizes footwear, and creates a dramatic perspective distinct from Frames 1 and 2. 4. Side-On Compression Frame (Long Lens)Camera placed far to one side of the subject, using a tighter focal length to compress space. The subject appears in clean profile or near-profile, showcasing garment structure in a flattened, editorial manner. 5. Intimate Close Portrait From an Unexpected HeightCamera positioned very close to the subject’s face (or upper torso) but slightly above or below eye level. The angle should feel fashion-editorial, not conventional — offset, elegant, and expressive. 6. Extreme Detail Frame From a Non-Intuitive AngleCamera positioned extremely close to a wardrobe detail, accessory, or texture, but from an unusual spatial direction (e.g., from below, from behind, from the side of a neckline). This must be a striking, abstract, editorial detail frame. Continuity & Technical Requirements Maintain perfect wardrobe fidelity in every frame: exact garment type, silhouette, material, color, texture, stitching, accessories, closures, jewelry, shoes, hair, and makeup. Environment, textures, and lighting must remain consistent. Depth of field shifts naturally with focal length (deep for distant shots, shallow for close/detail shots). Photoreal textures and physically plausible light behavior required. Frames must feel like different camera placements within the same scene, not different scenes. All keyframes must be the exact same aspect ratio, and exactly 6 keyframes should be output. Maintain the exact visual style in all keyframes: Shot on Fuji Velvia film with a hard flash. The light is concentrated on the subject and fades slightly toward the edges of the frame. The image is over exposed showing significant film grain and is oversaturated. The skin appears shiny (almost oily), and there are harsh white reflections on the glasses frames.

If you're adapting this, spend some time with it. It is effectively a 6x prompt. You can also adapt the frames from the contact for generating additional keyframes. I did this for the Patek, Reebok and Gameboy images. Generate the contact sheet at 2k or 4k, it will give you more detail for the extraction step.

Use Kling 2.6 for the I2V, it's the best, but you can only use first+last frame in the webUI at If you want to go over the API then I'd go for Kling 2.5. When prompting for video, go for smooth motion and minimal model movement. Example prompts: "The camera very slowly and smoothly lowers on a boom. The subject moves barely moves, and is extremely deliberate and thoughtful in his movement." "The camera very slowly and smoothly orbits while zooming on the glasses. The subject moves barely moves, and is extremely deliberate and thoughtful in his movement."

I used for stitching, applying the ease curves, and adding the audio. It's another tool I'm working on, also available for free and a work in progress. For best results use chrome desktop. I'm not sure how well it works for high res video.

I have all the prompts, more tips, and other bits written up here.

This came out insanely good. What you you think?

Oh nice, good consistency on the ring

That was so hard man... and I missed one shot tbh if you noticed :D. Learned that if I get specific about the ring in the problematic shots it will work. You created something truly amazing.

Thank you for the instructions! I just made this one. Literally just from a screen shot of a video of myself in the car, and Nano Banana, VEO 3.1, and then my edits in Final Cut did the rest. I used yours as the direct inspiration, and added my style to it.

Used Veo 3, but very cool work flow. I had issues with the contact sheet grids, and some of the lost fine details, but I can see this being applied to a lot of different camera angles, motions, models, backgrounds.

Nice one!

The game boy. 🔥🚒🧯🔥

Legend! I gave it a try, came out pretty rad!

Lmao!! Is that Powell?? 😂

JPow himself

The gameboy did it for me. Well done.

Driiiiippppp 🔥🔥🔥

Glad I found you again

i’d say this is BETTER than real

Thanks! This workflow would rip for small fashion brands IMO, why even shoot anymore

Oh my!!!

This is such a solid approach. Contact sheet prompting with NB Pro really boosts style stability. Thanks for opening up your workflow — learned a lot.

Really cool. The gameboy killed me haha

lets goo

This is probably one of the best nano banana “tutorials” out there

i would say the key is in having good starting images with different angles / poses but same background otherwise there will be hallucinations or just too little change between scenes, really cool

Hey, Let's connect for collaboration

my workflow is mostly just pressing buttons and pretending i meant to do that

This is fire 🔥 How's the consistency across the contact sheet? I've been struggling with Nano Banana keeping the same model/style across multiple generations. Any specific tricks you're using in your prompts?

Thanks Rajan, start with a good image in the photographic style you're after. I spent probably 30 or 40 generations refining the prompt for Tim. Then lean hard on the model about maintaining the style, top part of the contact sheet prompt here is key. "Analyze the input image and silently inventory all fashion-critical details: the subject(s), exact wardrobe pieces, materials, colors, textures, accessories, hair, makeup, body proportions, environment, set geometry, light direction, and shadow quality. All wardrobe, styling, hair, makeup, lighting, environment, and color grade must remain 100% unchanged across all frames. Do not add or remove anything. Do not reinterpret materials or colors. Do not output any reasoning. Perfectly replicate the exact facial features of the model." So use NBP in the contact sheet step for framing and positioning, rather than for style. I also reinforced the photographic style down the bottom of the prompt. "Maintain the exact visual style in all keyframes, where the image is shot on fuji velvia film with a hard flash, the light is concentrated on the subject and fades slightly toward the edges of the frame. The image is over exposed showing significant film grain and is oversaturated. The skin appears shiny (almost oily), and there are harsh white reflections on the glasses frames."

Love this so much

grandpa got dat drip

icing out jpow is crazy

The FED ring is sick right

Dope! This is perfect for music videos

This is absolutely beautiful

Hi mate, I have a problem with NBP. I try to create a cartoon charackter wich has "Traits" like different hats or gloves. I need traits on a separate layer but on exactly same place, to programatically overlay them later (for a NFT) 1/2

hi Willie, did you check or find any encoding issues with our 'stutter' issue with playback on main posts?

I made some changes but it's hard to know what the issue was, if you DM me the original mp4 I can double check!

Your thread is very popular today! #TopUnroll 🙏🏼@embikey_fr for 🥇unroll

This is DOPE

This is so fucking dope.

what's the total cost per video? and have you thought of creating a SaaS to wrap this tutorial to make it more accessible?

Coolll

Awesome! Superbly executed and highly stylized absolutely love this. Thanks for sharing your approach.

thats soooooooooooo goooooooooooood
