Hybrid reel
Stills built in 3ds Max and Corona, refined in ComfyUI and animated with Kling and other AI video models – one hybrid pipeline from model to moving image.

Get in touch →Goal
A React app so the whole team can use the workflow.
Pipeline · Character Swap
Character in, video out – without opening ComfyUI.
Upload a character and a video, fill in four fields, click Generate – no ComfyUI knowledge needed. I keep graph, models and parameters stable in one place, so the whole team gets the same quality.

Architecture
01 · Team
React app (built by me)
Two uploads, four plain-language fields, queue and sampler steps live, result synced next to the original.
02 · Gateway
FastAPI
Validates files, trims the video, turns the fields into the technical prompt, one job per GPU, logs seed and output.
03 · GPU
ComfyUI · video model
Runs only the approved workflow. Internal network only, never publicly reachable – the graph stays locked.
Inside the workflow
- Design sheet + video
- Qwen3-VL
- Video model + LoRA
- Video- & Audio-VAE
- MP4
Monitoring
My own Python tool delivers the data.
perfmon · Python Sample data
I built a Python tool that measures every run.
It runs the workflow through the ComfyUI API, measures time per node, VRAM and GPU utilisation, and builds a report automatically.
68 % of the time in the sampler – that is where optimising pays off.
View report ↗Principles
Six decisions that keep it stable.
01
Prompt from fields
The team describes, the system writes – with the rules that work.
02
Graph locked
Only prompt, image, video, duration and seed can change. Never sampler, models or LoRA.
03
Design sheet
Seven views as the only image reference – the character holds even when the head turns.
04
Original sound
Audio comes from the source video. Lips and timing stay believable.
05
Fixed seed
Compare variants fairly; “again with a new seed” is one click.
06
Safe
ComfyUI never exposed, file and length limits, metadata stripped.
Prompt, parameters and workflow file – I show them live in a conversation.
Get in touch →Practice
Architecture, before it exists.
Practice · Real-time archviz
Light, material and camera – delivered at frame rate.
I build high-end real-time experiences and AI-driven tools for architecture, virtual production and interactive media – light, material and camera held to offline quality, plus the Python and AI pipelines behind them.
