Already Made an AI Character? How to Make It Talk
You do not have to redesign a character you built elsewhere. Upload the sheet as your avatar board, and every still and clip after that anchors to it. Here is the workflow and its limits.
HexUGC is an AI influencer generator: you fix one character once, then generate vertical talking-to-camera videos from it for as long as you keep using it. If that character already exists, because you designed it in Midjourney, Nano Banana, Stable Diffusion or anything else, you do not have to rebuild it here. Upload the character sheet you already have and it becomes the identity that every still and every clip anchors to.
One portrait is not enough to animate
Most people arrive with a single image. It is usually a good one, front-facing, and it is the reason they want video in the first place. The problem is that one angle carries one angle of information. Ask a model to put that face in a kitchen, three-quarters on, and it invents the half of the head it has never seen. Do that twenty times and you have twenty cousins.
What holds a character still is a sheet: front, left, right and back, head to toe, in one image. That is what HexUGC calls a board, and it anchors everything downstream. Why characters drift, and what still slips through, is covered in how to keep the same AI character in every video.
Uploading the sheet you already made
Create an avatar, open its board tab, and upload your sheet. It becomes the active board immediately and joins the board history alongside anything you generate later, so you can switch back to it at any point. Nothing is generated, so the upload itself costs nothing.
A 16:9 sheet carrying the four views works best, because that is the shape the rest of the pipeline expects. A front view on its own is accepted and will still be a weaker anchor than a full turnaround. If your character exists only as a portrait, the better route is to describe it in the board generator and attach your image as a likeness reference: what comes back is a turnaround of that person rather than a copy of your file.
What happens after the board
The board gates the rest of the studio. Once one exists, create-image turns build a library of stills of your character in different settings, angles and outfits, each anchored on the board rather than on the previous still. You keep the ones that look right.
A video is then a matter of picking stills. Each scene takes one still and a line of direction, and the script is either written from a freeform brief and edited, or pasted in whole. A voice is stamped on the avatar at creation and can be changed per project, which choosing an AI influencer voice goes into. The still is lip-synced to the voiceover, scenes are stitched, word-synced captions are burned in, and you download a 9:16 MP4. If you want the performance to follow a clip you have already seen work, motion reference drives the scene from a supplied video, covered in turning a TikTok into an AI avatar ad.
What this does not do
It does not preserve an unusual art style exactly. Stills are generated from your board, not cropped out of it, so a heavily stylised character, a flat illustration or a particular render look, tends to drift towards photographic over a few turns. A photoreal human sheet survives this best, and an anime or 3D character is the weakest case.
It does not edit the sheet you uploaded. Regenerating a board is a fresh roll of a written description, not a retouch of an image, so treat your upload as final and keep the source file.
There is no batch or multi-variant generation. One video at a time, and fan-out is on our roadmap rather than shipped. There is no publishing or scheduling either, so you download the MP4 and post it yourself. And there is no free trial, so the first thing you do here is pay.
What it costs
A 10 second voiced video is 28 credits. The first video is $5 for 50 credits, Starter at $15 a month is 300 credits and works out at roughly 10 videos, and Creator at $30 is 600 credits, about 21. Uploading a board is free, each library still is 5 credits, and a generation that fails returns its credits to your balance.
Start from the character you have
The expensive part of an AI influencer account is not the videos, it is the identity: a face people recognise between posts. If you have already built that face, the work is done and the only thing missing is a pipeline that will not quietly redraw it.
