Make a Week of TikTok and Reels Videos in One Sitting
Short-form accounts die from cadence, not ideas. Here is the real timing of one AI influencer video, step by step, and how a week of TikTok and Instagram Reels posts fits into a single sitting.
Short-form accounts rarely die from a shortage of ideas. They die in week three, when whoever runs them works out what three posts a week costs in filming, lighting, retakes and editing, and quietly stops. HexUGC removes that specific bottleneck: you design one AI influencer once, then generate 9:16 talking-to-camera videos from that character in minutes, and post them to TikTok and Instagram Reels yourself.
Cadence is the variable you actually control
Three things decide whether an account grows: the hook, the niche and the number of posts. The first two take taste and a few weeks of being wrong. The third is pure logistics, and it is the one that collapses first, because production time is what makes a plan of three posts a week turn into four posts total.
So the useful question about any generation tool is not whether it can make a nice video. It is whether it can hold a cadence you set in month one all the way through month three.
What one video actually takes
Here is a real run, measured end to end on a single voiced scene.
| Step | What happens | Roughly |
|---|---|---|
| Your part | Pick a still, direct it, write or accept the script | A minute or two |
| Script | Claude drafts from your creator direction, editable | 7 seconds |
| Voiceover | ElevenLabs speaks it in your character's voice | 7 seconds |
| Scene still | Nano Banana builds the shot from your library image | 35 seconds |
| Lip-sync | Kling animates the still to the audio | About 9 minutes |
| Stitch | ffmpeg joins the scenes and burns the captions | 17 seconds |
Two things matter in that table. The lip-sync dominates everything else, and it varies with clip length and how busy the vendor is, so treat ten minutes as a normal run rather than a guarantee. And your own share of it is a minute or two at the front. The rest is a queue you walk away from, which is the actual difference from filming: the work does not scale with your attention.
Scenes inside one project run in parallel, so a three-scene video is roughly the slowest scene plus the stitch, not three videos back to back.
A week of posts, and what it costs
Three posts a week is three runs. That is about five minutes of your hands on the keyboard and half an hour of machine time you are not watching, which fits in one sitting on a Sunday.
The bill is easy to work out because credits are the unit and one credit is $0.10. A 10-second voiced video is 28 credits, so three of them is 84 credits, about $8.40. Length is the biggest lever you have: a 20-second video is closer to 48 credits, so shorter posts buy more posts. Plans work out to roughly 10, 35 and 107 videos, and the opening 50 credits are $2 so you can see the output before committing to a cadence.
One file, TikTok and Reels both
The export is a native 9:16 H.264 MP4 at 1080x1920, which is the same shape TikTok, Reels and Shorts all want. Captions are burned in and word-synced, because most of the feed watches on mute and a clip without them is discarded before the voice matters.
There is no cross-posting magic here. One generation gives you one file that is correct for all three surfaces, so the per-platform work is uploading it and writing a caption.
Why the same face makes the speed compound
Speed on its own gets you a pile of clips. Speed plus one recognisable person gets you an account, because the follow lands on a character rather than on a video, and an account showing a different stranger every post reads as a content farm.
That is what the character board does. One sheet of your influencer front, left, right and back, with every later still anchored to it, so video forty still looks like video one. Building the character and choosing a cadence is the setup job you do once. The other half of looking native is movement: motion reference lets you hand over a reference clip, a TikTok URL included, and your character performs its movement and timing while keeping their own likeness. We wrote up how that works separately.
What this does not do
Each video is its own run. Batch generation, several variants from one action, is on our roadmap rather than shipped, so a week of posts is a sitting rather than a button.
There is no publishing or scheduling to TikTok, Instagram or YouTube. You download the MP4 and upload it yourself.
And ten minutes a video removes the production bottleneck, not the judgement. If the hook is weak the speed just gets you to the wrong answer faster, which is at least useful information sooner.
Where to start
Pick the cadence you can hold rather than the one that sounds serious. Two posts a week for three months beats five a week for nine days, it costs less, and it gives the character time to settle before it has to carry an offer.
