Promo Video Maker 2026
Definition, input specs, model runtimes, and workflow steps for creating 5- to 15-second marketing clips with current 2026 AI video models on Flixly.
TL;DR
A promo video maker converts text or reference images into 5- to 15-second marketing clips using models like Seedance 2.0, Kling 3.0, and Veo 3.1. Inputs are 280-character prompts or 1024-pixel images. Outputs are 1080p MP4 files with optional music and captions. Typical credit cost runs 3 to 6 per second depending on the model.
What a promo video maker produces
A promo video maker turns static prompts into short marketing clips that run 5 to 15 seconds at 1080p or 4K. It does not edit existing footage or add manual keyframes the way traditional software does.
How generation works under the hood
Models such as Seedance 2.0 and Veo 3.1 process the prompt in two stages. First they create a low-resolution motion map, then they refine it with a second pass at full resolution. Kling 3.0 adds temporal consistency checks that reduce flicker on character faces across 30-frame sequences.
The system accepts either a text string up to 280 characters or an image reference sized 1024 by 1024 pixels. Output files are delivered as H.264 MP4 at 24 or 30 fps.
Concrete inputs and outputs
Users supply a product name, a 10-word benefit line, and a reference photo. The tool returns a 1080p clip with baked-in motion, background music at 128 kbps, and optional auto-captions timed to the beat.
- Seedance 2.0: 8-second default, 720p to 4K, 4 credits per second.
- Kling 3.0: 12-second clips, supports 16:9 and 9:16, 6 credits per second.
- Wan 2.7: 5-second loops, 1080p only, 3 credits per second.
Real workflow examples
A product launch team uploads a 1024-by-1024 logo to Image to Video. They add the prompt "slow zoom on logo with floating particles" and select Seedance 2.0. The result is a 10-second clip ready for Instagram Stories.
A SaaS company generates a character-consistent spokesperson using Reference to Video. They reuse the same reference image across three clips, keeping face ID above 0.92 similarity.
Retail brands run Motion Poster on static hero images to create 6-second loops that play on landing pages. The tool outputs a 1080p file under 4 MB.
Where these clips appear
Generated videos land in email headers, paid social ads, and product pages. Teams export 9:16 versions for TikTok and 16:9 versions for YouTube pre-roll. Lip sync is added afterward on Lip Sync Video when the script includes spoken lines.
Music is pulled from Music Generation at 15-second stems that match the clip length exactly.
