Media plans often assign one AI video tool to every slot. A Free Image to video AI stack works better when teams route by job shape, not by whichever model was clicked last.
My rule is simple: for format or copy tests, start in Seedance Fast with explicit duration and ratio controls. For production-value homepage loops, move the same brief to Veo 3.1 Lite and spend credits where polish is visible.
Seedance and Veo Fail in Opposite Directions
Seedance 2.0 on Image To Video AI is built for repeatable iteration, with Standard and Fast variants, durations up to 15 seconds, resolutions up to 4K on Standard, and ratios including 21:9 and 1:1. That breadth suits multiple cuts for hook testing.
Veo 3.1 focuses on cinematic motion language, with Lite, Fast, and Quality tiers, clips up to 8 seconds, and output up to 4K where supported. It shines when camera movement and atmosphere carry the sell.
Veo costs calendar time; Seedance Fast can lose polished hero motion.
Traffic Sheet Matrix Before Anyone Opens a Prompt
| Deliverable | Start model | Why |
| Story A/B hooks | Seedance 2.0 Fast | Cheaper format sweeps |
| Homepage hero loop | Veo 3.1 Lite | Premium camera language |
| Pack-shot motion | Seedance first-frame | Preserves approved composition |
Real Campaign Week Split Across Both Model Lanes
Run Seedance Fast for story tests, then take winning hook language into Veo Lite for an 8-second 16:9 hero. Reopen Seedance first-frame only if the hero fails label legibility.
Product Limits That Routing Cannot Fix Alone
Free-tier exploration includes daily check-in credits but not watermark-free downloads; client-facing heroes need the $29.9 monthly plan for 800 credits.
Some configurations cost around 200 credits; shorter Seedance runs may cost less. Use Fast for exploratory rows and Quality Veo for client-facing assets.
Write the Lane on the Brief Before You Generate
Write the routing line on the brief. Generate tests Fast. Generate heroes Lite. Ship only what survives the client screen.
If your trafficking sheet still says one AI tool for all rows, split it before launch.
Name exports by ratio and model. Image To Video AI only reduces campaign debt when the lane is named before credits burn.
