Grok Imagine Video 1.5 Preview Pricing: Credits Per Second at 480p, 720p and 1080p
Exact per-second credit costs for Grok Imagine Video 1.5 Preview on VdoBloom, from 2 credits for a 1-second 480p clip to 75 for 15 seconds at 1080p, with dollar conversions and budget math.
Grok Imagine Video 1.5 Preview is billed per second on VdoBloom: 480p costs 2 credits for 1 second rising to 23 credits for 15 seconds, 720p is exactly 3 credits per second, and 1080p is exactly 5 credits per second — so a 5-second 720p clip is 15 credits, about $0.75 at the Lite rate. Because duration is selectable at every whole second from 1 to 15, the pricing table has 45 real entries rather than the usual two or three preset lengths, and you only pay for the seconds you actually asked for.
That is the whole argument for this model’s pricing. On a model that offers only 5s and 10s, a 7-second clip costs you a 10-second render. Here it costs 21 credits at 720p, and nothing gets trimmed on the cutting room floor that you already paid for.
The credit rate at each resolution
xAI’s Grok Imagine Video 1.5 Preview is image-to-video only on VdoBloom — you supply a still and it animates it. It offers three resolutions (480p, 720p, 1080p), durations of 1 to 15 whole seconds, and seven aspect ratios: 1:1, 16:9, 9:16, 4:3, 3:4, 3:2 and 2:3. It carries a 5.0 rating and the HOT content label, the more flexible filtering tier.
The per-second rates from the live credit table are:
- 480p: 1.5 credits per second, rounded up — so odd seconds land on a half-credit that rounds in your favour on even lengths
- 720p: exactly 3 credits per second, no rounding
- 1080p: exactly 5 credits per second, no rounding
Credits convert at a fixed rate: Lite is $15 for 300 credits, so one credit is $0.05. Every dollar column below uses that rate.
| Duration | 480p credits | 480p cost | 720p credits | 720p cost | 1080p credits | 1080p cost |
|---|---|---|---|---|---|---|
| 1 second | 2 | $0.10 | 3 | $0.15 | 5 | $0.25 |
| 2 seconds | 3 | $0.15 | 6 | $0.30 | 10 | $0.50 |
| 3 seconds | 5 | $0.25 | 9 | $0.45 | 15 | $0.75 |
| 4 seconds | 6 | $0.30 | 12 | $0.60 | 20 | $1.00 |
| 5 seconds | 8 | $0.40 | 15 | $0.75 | 25 | $1.25 |
| 6 seconds | 9 | $0.45 | 18 | $0.90 | 30 | $1.50 |
| 7 seconds | 11 | $0.55 | 21 | $1.05 | 35 | $1.75 |
| 8 seconds | 12 | $0.60 | 24 | $1.20 | 40 | $2.00 |
| 10 seconds | 15 | $0.75 | 30 | $1.50 | 50 | $2.50 |
| 12 seconds | 18 | $0.90 | 36 | $1.80 | 60 | $3.00 |
| 15 seconds | 23 | $1.15 | 45 | $2.25 | 75 | $3.75 |
The intermediate lengths follow the same rule: 9s is 14 / 27 / 45 credits, 11s is 17 / 33 / 55, 13s is 20 / 39 / 65 and 14s is 21 / 42 / 70 across 480p, 720p and 1080p respectively.
What the free credits buy
New accounts get 10 credits with no card. Against this model that is one 6-second 480p clip (9 credits), one 3-second 720p clip (9 credits), or two 1-second 1080p renders (10 credits). Drafting at 480p is the sensible use of a free allowance here — at 1.5 credits a second, you can see whether the motion in your source image works before spending 1080p money on it.
The draft-then-finish math
The gap between resolutions is where budgets are won. 1080p costs 3.33 times what 480p costs for the same length. So a workflow of three 480p drafts followed by one 1080p final, at 8 seconds each, looks like this:
- 3 drafts at 480p 8s = 36 credits ($1.80)
- 1 final at 1080p 8s = 40 credits ($2.00)
- Total: 76 credits, $3.80
Running all four attempts at 1080p instead costs 160 credits, or $8.00. The draft pass more than halves the bill, and the 480p render is fast enough that you are not waiting around to learn the animation direction was wrong.
Against other image-to-video options
Here is the 720p 5-second price point compared with other image-to-video models in the same credit table, which is the fairest single yardstick.
| Model | 720p 5s credits | Cost on Lite | Duration options |
|---|---|---|---|
| Seedance V1 Lite I2V | 9 | $0.45 | 5s or 10s only |
| Seedance V1 Pro Fast I2V | 7 | $0.35 | 5s or 10s only |
| P-Video | 8 | $0.40 | 1–15s |
| Grok Imagine Video 1.5 Preview | 15 | $0.75 | 1–15s, every whole second |
Read honestly, this model is not the cheap option at 720p. What the extra credits buy is the 5.0 rating, the seven aspect ratios including the 3:2 and 2:3 orientations cameras actually shoot in, and per-second control. If you need a 12-second vertical clip cut to a beat, the cheaper models cannot produce it at all — they would hand you 10 seconds and you would still be paying for a length you did not want.
Buying credits for it
At the Lite rate a full month of 300 credits is 20 clips at 720p 5s, 12 clips at 1080p 5s, or four 15-second 1080p finals. One-time packs from $2.49 for 75 credits never expire, which suits occasional 480p drafting bursts; annual billing lowers the per-credit rate substantially if you are generating weekly. The rates sit on the pricing page, and paid plans download without a watermark with commercial rights.
Generate from the image-to-video tab — this model does not appear on the text-to-video tab because it requires a source image. The full spec sheet is on the Grok Imagine Video 1.5 Preview model page. If you are animating a photo of a real person, you must have that person’s consent before you generate.
One last cost note: the credit charge is shown before you confirm each run, and it is calculated from the duration and resolution you have selected at that moment. Changing the duration slider changes the quoted number immediately, which is the fastest way to see the per-second rate for yourself.
Frequently asked questions
How much does a 10-second Grok Imagine Video 1.5 Preview clip cost?
15 credits at 480p ($0.75 at the Lite rate), 30 credits at 720p ($1.50), or 50 credits at 1080p ($2.50). Those are the exact values in the credit table, not estimates.
Is the pricing linear with duration?
At 720p and 1080p, yes — exactly 3 and 5 credits per second with no rounding, so doubling the length doubles the price. At 480p the rate is 1.5 credits per second rounded up, so 1 second costs 2 credits rather than 1.5, and odd-second lengths carry a fractional round-up.
Can I generate text-to-video with this model?
No. Grok Imagine Video 1.5 Preview is image-to-video only on VdoBloom, so it appears on the image-to-video tab and requires a source still. Models that cover both directions are listed on the model directory.
Does aspect ratio change the credit cost?
No. All seven ratios — 1:1, 16:9, 9:16, 4:3, 3:4, 3:2 and 2:3 — cost the same at a given resolution and duration. Only those two settings move the price.
What does the HOT content label mean for pricing?
Nothing directly — the label describes content-filter strictness, not cost. It means this model is on the more flexible tier that handles swimwear, dance, fitness and fashion prompts stricter models refuse. Explicit and illegal content stays blocked regardless of tier.
