AI Video Generator for Marketing Teams
A marketing team's bottleneck is rarely the hero film. It is variant volume: five hooks for the same offer, a vertical cut and a wide cut, a version for each region, and enough shorts to keep the paid social account fed between campaigns. Every one of those is cheap creative work that still consumes an editor's week.
VdoBloom splits that work into tools that map onto the actual tasks. Ad Variants writes one script per hook angle from a single brief. Clip Studio turns a webinar or podcast into vertical shorts with burned-in captions. Video-to-Prompt reverse-engineers a format you admire into a prompt you can reuse. Testimonial and Spokesperson cover the two different framings of a talking human. Underneath all of them sits the same roster of 54 video model variants across 14 families.
The practical advantage for a team is that the creative decision and the render cost are separated. You lock the hook and the script at 480p for 38 credits per variant on Seedance 2 — or about 4 credits on Seedance 1.5 Pro — kill the ones that do not test, and only then pay for a 1080p master of the winner. Nothing about the brief changes between those two runs.
What this tool does
- Ad Variants generates one script per hook angle across five fixed styles — Curiosity, Problem–Solution, Social Proof, Urgency and Humor — from a single product brief, so a test cell is defined by its hook rather than by a rewrite.
- Clip Studio accepts a source video up to 90 minutes or 1 GB and returns up to 5 vertical 9:16 clips with word-timed burned-in captions. It charges 2 credits per source minute with a 4-credit minimum per job.
- Clip Studio rejects source videos under 60 seconds by design — it is a repurposing tool for long-form recordings, not a general editor.
- Video-to-Prompt reverse-engineers an existing video into a reusable generation prompt at 6 credits per source minute with a 10-credit minimum, plus 5 credits per correction pass.
- The roster is 54 video model variants across 14 families — Runway, Veo 3.1, Kling, Seedance, Wan, MiniMax H3, Hailuo, PixVerse, Vidu, SkyReels V4, Gemini Omni, HappyHorse, Grok Imagine and P-Video — so a locked creative can be re-rendered on a cheaper model without touching the brief.
- Aspect ratio is a per-model constraint, not a global setting: MiniMax H3 text-to-video and Seedance 2 both support 21:9 through 9:16, while Gemini Omni is limited to 16:9 and 9:16 but renders up to 4K.
- A five-hook test costs 190 credits at Seedance 2 480p/5s (38 per variant), or about 20 credits if you switch the picker to Seedance 1.5 Pro at 480p (0.75 credits/sec), before committing to a Seedance 2 1080p/5s master at 203 credits.
- Testimonial and Spokesperson are separate tools because the prompt framing differs: Testimonial frames the speaker as an authentic customer review, Spokesperson frames them as your brand's presenter and saves them for reuse.
How it works
1.Write one brief, not five
In Ad Variants, enter the product, the offer and the audience once. The tool produces a separate script for each of the five hook styles — Curiosity, Problem–Solution, Social Proof, Urgency and Humor — so the variable under test is the hook, isolated from copy quality.
2.Render the test cells cheap
The Ad Variants tab renders on Seedance 2 by default; drop it to 480p and 5 seconds and each clip is 38 credits, so a five-hook test is 190. To test cheaper, switch the picker to Seedance 1.5 Pro at 480p — 0.75 credits/sec, about 4 credits per 5-second clip. Ship those to your ad platform and let the click-through data pick the winner instead of the room.
3.Master only the winner
Take the winning hook back into the same tab and raise the resolution to 1080p on Seedance 2, the tab's default model. The prompt, the script and the framing are unchanged; only the resolution moves. That is the 203-credit line item, spent once.
4.Mine your long-form library
Feed a webinar, panel or podcast recording into Clip Studio — up to 90 minutes or 1 GB — and choose how many clips you want, up to 5. It transcribes with word-level timestamps, picks the strongest moments, reframes to 9:16 and burns the captions in. A 45-minute recording costs 90 credits.
5.Reverse-engineer formats you cannot brief
When a competitor's format works and nobody can describe why, run it through Video-to-Prompt at 6 credits per source minute. You get a structured generation prompt you can edit and reuse — the format, not the footage.
Frequently asked questions
How many ad variants can I generate from one brief?
Ad Variants covers five fixed hook styles — Curiosity, Problem–Solution, Social Proof, Urgency and Humor — and writes a distinct script and title for each from a single brief. You then choose which of the five to render as video.
What does it cost to repurpose a one-hour webinar?
Clip Studio is priced at 2 credits per source minute with a 4-credit minimum per job, so a 60-minute recording costs 120 credits regardless of how many of the up-to-5 clips you request. The estimate is shown before you submit, calculated from the file's actual duration.
Can I get 21:9 or 4K output?
Both exist but on different models. MiniMax H3 text-to-video and Seedance 2 offer 21:9 through 9:16 aspect ratios. Gemini Omni renders up to 4K but is restricted to 16:9 and 9:16. The settings panel only shows the ratios and resolutions the selected model actually accepts.
Is there a way to keep one presenter consistent across a campaign?
Yes — the Spokesperson tool saves a generated presenter to browser storage and reuses it across videos, with tone presets (Confident, Friendly, Expert, Energetic, Calm) and a free-text accent field. Testimonial deliberately does the opposite, generating a fresh face each time so reviews do not look like the same actor.
Can we re-render an approved creative more cheaply?
Yes. Model choice is independent of the brief, so an approved script and framing can be re-run at a lower tier. Seedance 2 is 38 credits at 480p/5s against 203 credits at 1080p/5s, and switching the picker to Seedance 1.5 Pro at 480p drops a 5-second test to about 4 credits.
Does Clip Studio work on short clips?
No. It refuses source video under 60 seconds and caps input at 90 minutes or 1 GB. It is built specifically for cutting long recordings down, and the interface points you to Video Edit for short footage.
