Question 1

What can I make with Grok Imagine Video 1.5?

Accepted Answer

Social clips, ad creative, product films, character shots, and sequences built from stills you already have. Attach a photo, a render, or a generated image, describe the motion, and the model turns it into a clip with sound. Clips run from one to fifteen seconds at 480p or 720p, in seven frame shapes plus an auto setting that follows your image. It is the pick when the look is already decided and only the movement is left.

Question 2

Do I need a reference image for Grok Imagine Video 1.5?

Accepted Answer

Yes. 1.5 animates an image, so the run needs one and will not start without it. Upload a photo or point at a file you made earlier in Visual Sandbox. For a clip from a prompt alone, use Grok Imagine Video, the sibling model that still takes text on its own. Grok Imagine 2.0, the image model from the same family, is a quick way to build the frame first and then bring it here.

Question 3

Does Grok Imagine Video 1.5 generate audio?

Accepted Answer

Yes, on every clip. Dialogue, ambient noise, and effects come out of the same pass as the picture, so speech lands on lips and sounds sit on the action. There is no switch to turn the audio off. Describe what you want to hear in the same detail you describe what you want to see. "Rain on a metal roof, a kettle whistling in the next room" gets you further than "background sound". The result arrives as one MP4 with the sound baked in.

Question 4

What is the difference between Grok Imagine Video and Grok Imagine Video 1.5?

Accepted Answer

1.5 is the newer generation and it animates an image only. It stays closer to the frame you hand it, holding the detail and the lighting of the source instead of reinterpreting the scene, and it comes back faster. Grok Imagine Video is the one to pick when you have no starting image, and it costs less per second. xAI ships 1.5 as a preview, so treat it as the newer and less settled of the two. Both cover the same lengths, frame shapes, and resolutions, and both make their own audio.

Question 5

How closely does Grok Imagine Video 1.5 follow my image?

Accepted Answer

Closely. The model continues the picture rather than redrawing it, so faces, wardrobe, product detail, and the direction of the light survive into the clip. That is what makes it work for a sequence: animate several frames that already share a look and the shots cut together. Give the model a clean, well-lit frame and keep the subject fully in view. A soft or cluttered source is the usual reason a clip drifts.

Question 6

What aspect ratios, resolutions, and lengths does Grok Imagine Video 1.5 support?

Accepted Answer

Seven frame shapes: 16:9, 4:3, 1:1, 9:16, 3:4, 3:2, and 2:3. There is also an auto setting, which takes the shape of the image you attach and is the safe choice here. Resolution is 480p or 720p, and the rate per second is the same either way, so 720p is the default rather than an upgrade. Length runs from one to fifteen seconds, starting at five. For a longer piece, chain clips: take the last frame of one and attach it as the image for the next.

Question 7

How do I write a prompt for Grok Imagine Video 1.5?

Accepted Answer

Write motion, not composition. The image has already settled the subject, the framing, and the palette, so spend the prompt on what changes: one clear action, the camera move, the pace, and the sound. Name the camera, because the frame stays still unless you ask it to travel: slow push in, tracking shot alongside, a gentle drift to the left. Use strong verbs for force and pace. Write the lines you want spoken into the prompt and say who speaks them.

Question 8

How long does a Grok Imagine Video 1.5 clip take?

Accepted Answer

Around thirty seconds for a five second clip at 720p, measured end to end on Visual Sandbox. Longer clips take longer. That makes 1.5 the faster of the two Grok video models, so it is the better one to iterate on once you have a frame you like. The run happens in the background, so you can start the next one while the first finishes.

Question 9

How much does a Grok Imagine Video 1.5 clip cost?

Accepted Answer

A few cents per second of video. Resolution does not move the rate, so a 720p clip costs the same per second as 480p. You pay for the seconds delivered rather than the seconds requested, so a clip that comes back shorter than you asked for costs less. 1.5 charges more per second than Grok Imagine Video. There is no subscription, no weekly allowance, and no monthly minimum. Visual Sandbox shows the exact price before you generate and charges when the clip is delivered.

Question 10

Can I use Grok Imagine Video 1.5 clips commercially?

Accepted Answer

Yes. xAI's terms leave ownership of the output with you. You are responsible for the image you attach, the prompt, and the final use, especially where the clip carries a likeness, a logo, a voice, or copyrighted material. Some places require content to be labelled as AI generated, so check the rule where the work will run. Visual Sandbox also runs Veo 3.1, Seedance 2.5, and Kling 3.0 Omni in the same composer if you want to compare takes before you deliver.
