Vidnebu's AI stock video generator for Shorts builds 9:16 vertical videos from licensed stock footage matched to your script, with burned-in captions and voiceover for TikTok, Reels, and YouTube Shorts.
Real footage, vertical framing, and captions that survive the platform interface. Vidnebu reads your script, matches licensed stock clips to each beat, and assembles a short that is ready to post.
It is the most economical way to publish short-form at volume — the format where volume matters most, because reach is decided by iteration rather than by polish.
Short-form reach is won by posting consistently and letting the algorithm find the winners, not by perfecting a single video. Stock-based shorts cost the fewest credits of any footage-based mode and render fastest, which is exactly what a daily posting cadence requires.
For finance, news commentary, health, education, and anything advice-shaped, real footage carries authority that generated imagery does not. Viewers are increasingly quick to spot AI video, and in categories where trust drives the follow, that recognition works against you.
Vidnebu derives a search query per scene from your script and selects clips that match what the line is actually about, then frames the selection for 9:16 rather than centre-cropping a landscape clip and hoping the subject survives.
Vidnebu splits it into beats and finds vertical-suitable stock for each one.
Replace any clip that does not fit before spending credits.
Captions and voiceover are added and the 9:16 short is exported.
Professional clips, matched per scene.
Selected and framed for 9:16, not centre-cropped.
The most economical footage-based short-form mode.
No generation step, so you can post the same day.
Text placed clear of platform UI overlays.
Override any match before rendering.
Cost, speed, and credibility. Stock shorts cost fewer credits and render faster, which supports a high posting cadence. In advice-shaped categories — finance, health, education — real footage also reads as more trustworthy than generated imagery.
Yes, clips come from a licensed professional library. That matters more in short-form than people expect, because a video that takes off is a video that gets scrutinised.
Consistency beats volume spikes. A sustainable daily or near-daily cadence outperforms bursts, because the platform needs repeated signal to work out who your audience is.
No. Clips are selected and framed for vertical rather than centre-cropped from landscape, which is the usual failure mode when repurposing footage.
Yes, on a paid plan. For paid social specifically, the UGC ad generator produces a format that typically converts better than a stock-footage short.
No. Vidnebu derives a query per scene from your script, so the matching is handled from the meaning of the line rather than from keywords you supply.
