Hero + B-roll in one place

All paid plans include a commercial license — use the promo on Meta Ads, TikTok, YouTube, OOH, sales decks, or as your homepage hero. No royalty per use, no platform restrictions.
How working ad teams split promo work by length
The same prompt costs different credits depending on whether it's a 30s hero, a 15s social cut, or a 6s bumper
30s 'owned channel' promo: spend per shot is forgiving
A gym owner on r/smallbusiness vented about spending $800 on a 30-second freelancer promo that came back "boring as hell, three weeks later" (r/smallbusiness, 2025-07, 23↑ 41c). The thread's 41 comments converged on the same math: a 30-second hero promo for your website, YouTube channel, or email landing page is roughly 6-8 stitched shots. That means the budget per shot is generous, and the premium tier starts to make sense. Consider Sora 2 Pro at 120 credits for a 4-second HD hero. Kling 3.0 runs 40 credits for a 5-second product macro. Veo 3.1 is 44 credits for a 4-second clip with native ambient audio. You pick the engine that matches the moment: a hero opening on Sora 2 Pro, product details on Kling 3.0, or ambient B-roll on Wan 2.6 at 30 credits per 5s. Stitch these in CapCut or DaVinci Resolve free. Total credit spend for a 30-second piece runs 400-600, around $9-13 on the Pro plan. Try this right now in the generator above with a prompt like "slow push-in on a luxury watch, dust motes in window light"—that's the kind of 5-second shot that can really elevate an owned-channel cut.
15s 'social organic' promo: hook-density math shifts the model choice
A SaaS owner said their promotional videos "are honestly holding us back from hitting growth targets" (r/smallbusiness, 2026-02, 23↑ 25c). They described quick phone edits showing how the platform saves 20 hours a month on billing, but nothing that actually converts. 15-second promos sit in the middle. They're too short for the full freelancer treatment, yet too long for just one AI clip. Here, the math shifts. Sora 2 Pro at 120 credits per 4-second hero is real money when you need 4 shots, around 480 credits just for hero density. Better economics: use Kling 2.5 Turbo at 25 credits per 5-second clip for three iterations of the hook. Lock the winner, then upgrade only that locked shot to Sora 2 Pro or Kling 3.0. A 15-second cut at this mix lands at 200-300 credits total, about $4-7 on the Pro plan. The hook is the only second that matters to the algorithm. The rest of the 15 seconds just has to not lose them. Try this in the generator with three hook variants ("steam rising from espresso," "watch face catching morning light," "shoe mid-stride on wet asphalt"), generate all three on Kling 2.5 Turbo, then watch them muted on your phone screen the way the feed actually views them.
6s 'paid bumper': where AI really shines
A performance marketer summarized $85k of AI vs human ad-spend testing on r/advertising and made a quieter point that gets lost in the AI-slop debate: "I have been mostly against AI ads, since everything I saw was obviously AI" (r/advertising, 2026-03, 10↑ 22c). The takeaway from the 22 comments was that 6-second formats are where AI really shines, specifically because you don't need narrative continuity—just one strong visual moment. At 5-6 seconds per generation, the cheap tier becomes interesting. Wan 2.6 at 30 credits for a 5-second clip is $0.67 on Pro. Pika 2.2 Standard at 20 credits is $0.44. You can run 20 variants of a single bumper for under $15 of credits. Look at them as a wall of 20 tiles, pick the two that read in the first frame muted. The traditional bumper agency price is $500-2,000 per polished version. The cost math says generate, screenshot the first frames, drop the bottom 18 of 20, recombine the top 2 with a logo card. Try this in the generator with a single prompt run twice on Wan 2.6 and twice on Pika 2.2. Four 5-second bumpers for 100 credits total, ready to plug into a Meta Reach campaign.

Our pick for promo clip
Kling 3.0
40 credits per 5s (~$0.89 on Pro)Best balance for promo work — cinematic camera moves, strong product realism, supports both people and objects. Mid-tier price means you can afford 8-12 hero shots per launch.
“We were quoted $12k for a launch promo by an agency. Generated all the assets in gVideo for under $100, edited it ourselves in CapCut, ran it as a Meta ad — same conversion rate as the agency-shot version we did the previous quarter.”
Common questions
What kinds of promos can I make with the AI promo video maker?
Common patterns: (1) product launches and reveals, (2) sale / discount announcements, (3) event promotions (webinars, conferences, store openings), (4) feature announcements for SaaS, (5) brand awareness campaigns, (6) seasonal campaigns (Black Friday, holiday). Anything that needs polished motion footage but not a full production crew.
How long should a typical promo video be?
30-60 seconds for paid social ads (TikTok, Meta), 15-30 seconds for organic social, 60-90 seconds for landing pages and homepage heroes. AI generates 4-10 second clips, so most promos are 6-12 stitched clips. The most-shared promos tend toward shorter (15-30s) for retention rate.
Can I match a specific brand color or style?
Describe it in the prompt. Phrases like 'on a clean white background,' 'warm sunset palette,' 'matte black product against deep navy,' or 'soft pastel lighting' steer the model. For exact brand color matching, generate the AI clips first, then color-grade in your editor (CapCut + LUT, DaVinci Resolve free) to match your style guide.
How does this compare to hiring an agency or freelancer?
Agencies: $5k-50k per promo, 4-8 weeks. Freelancers: $1.5k-5k, 2-3 weeks. AI video maker: $30-100 (credits + your time), 4-8 hours. The trade-off is that AI struggles with very specific brand stories that need real actors or real product close-ups (you can still combine: shoot one hero photo of your product, animate it with image-to-video, mix with AI B-roll).
Can I add a voiceover to the promo?
Two options: (a) Use Veo 3.1 in 'with audio' mode — it generates ambient + voiceover from your prompt directly into the clip. (b) Generate silent clips with cheaper models, then add narration in CapCut / DaVinci using your own voice or an AI TTS tool (ElevenLabs, OpenAI TTS). Most promo creators do option (b) for tighter control over pacing and brand voice.
What's a realistic monthly cost for promo work?
Depends on launch frequency. A brand running 1 promo per month with 10 hero clips averages ~600 credits = $13 on Starter ($9.99 with overage). A weekly campaign brand averages 2,000-3,000 credits/month = $26-30 on Pro. An agency running multiple client promos: 5,000-10,000+ credits/month, Studio plan ($99) is the right tier.
