Video resolution: 480p, 720p, 1080p & 4K
PrismPoster generates video at 480p, 720p, 1080p, or 4K — every resolution up to 15 seconds, with the same controls (image-to-video, first-and-last-frame continuity, references, and landscape or portrait framing — 16:9 or 9:16). Cost scales with both resolution and clip length, so a short 480p clip is the cheapest video you can make and a long 4K clip is the most expensive. Exact per-generation numbers are kept in one place; see credit costs by type and /pricing. Video generation is available on every plan, including Free — it's credit-gated, not tier-locked. The Free plan's 150 shared starter credits buy about three short clips (a 5-second 480p clip is 40 credits; a 5-second 720p clip costs 85, so the grant covers one of those instead). No resolution is locked to a tier — 1080p and 4K simply cost more than the Free allowance holds, so what the Creator plan and above add is the credit allotment and the larger monthly video allowance to reach them.
Which resolution should I pick?
- 480p — the cheapest option. Pick it when you want the most clips from your credits, for quick drafts, tests, or social placements where size doesn't matter.
- 720p — sharp HD for most social feeds.
- 1080p — crisp detail for larger screens.
- 4K — maximum detail for hero shots and big displays.
Every resolution supports the full clip length (up to 15 seconds) and the same creative controls; higher resolutions simply render more pixels per frame, so they cost more credits.
How do resolution and clip length affect credit cost?
Both push the cost up: a higher resolution renders more pixels per frame, and a longer clip renders more frames. A short 480p clip sits at the bottom of the range; a long 4K clip sits at the top. We don't print the exact ladder here so there's only one source to keep current — check credit costs by type for the live numbers.
Why does video ask me to upgrade?
Video generation runs on every plan, including Free — it draws from your shared credit balance rather than being locked to a tier. What prompts an upgrade is running low on credits, reaching for premium 1080p/4K, which the Free plan's 150 starter credits won't cover. Those starter credits are a one-time grant, not a monthly allowance — they do not refill. The multi-track timeline editor and publishing to Discover & PrismRadio are separate Creator-and-above features and aren't part of Free. (The Creator Cast stream tools themselves — Fan Clips, Fan Selfies, Fan Song Queue, OBS widgets — are free on every plan.)

Frequently Asked Questions
What resolutions can PrismPoster generate video at?
480p, 720p, 1080p, and 4K — all up to 15 seconds. The credit cost is shown before you generate, so you can trade resolution for more clips.
Which resolution gives me the most videos?
480p. It's the cheapest rung, so a given credit pool makes the most clips at 480p. Step up to 720p, 1080p, or 4K when you need more detail.
Can I generate video on the Free plan?
Yes. Video generation is on every plan — it's credit-gated, not tier-locked. The Free plan's 150 shared starter credits (pooled across Image, Music, and Video) realistically cover about three 5-second 480p clips at 40 credits each, alongside your images and music; a 5-second 720p clip costs 85 credits, so the grant covers one of those instead. Premium 1080p and 4K are offered on Free too, but they need far more credits than 150, so in practice they wait on a credit pack or on the larger allotment and monthly video allowance the Creator plan and above include.
