To make a longer Grok video, first choose between extending one continuous shot and editing several clips into a longer sequence. On APIXO, grok-video supports text-to-video and image-to-video generation for 6–30-second clips. It does not expose a video-input extension operation. For a longer finished edit, plan separate shots or use a still exported from one clip as an input for the next, then review the joins.
Start by testing the connection between two shots. This reveals whether the movement, appearance and sound fit together before you spend on a longer sequence.
Make a longer story: Editorial workflow diagram, not a tested model output
Choose what needs to continue
Method: Native video extension
Information carried into the next step: The source video, within the selected service’s limits
What to review: Subject, motion and sound across the join
Method: Still-frame continuation
Information carried into the next step: A visible state extracted from the previous clip
What to review: Whether the next clip resumes the intended action and camera movement
Method: Editing separate shots
Information carried into the next step: A shared brief and your chosen sequence
What to review: Narrative, product identity, color, timing and sound
A still frame does not contain the previous clip’s full motion history. A continuous turn or camera move therefore needs close review. A product introduction may work better as several shots connected by cuts, close-ups or inserts.
Check the Grok route before planning the edit
APIXO’s two Grok video routes have different published inputs and duration ranges:
APIXO route: grok-video
Modes: Text-to-video and image-to-video
Duration per request: Whole seconds from 6 to 30
Direct image inputs: 1–7 image URLs at 480p or 720p; one at 1080p
APIXO route: grok-imagine-video-1-5
Modes: Image-to-video
Duration per request: Whole seconds from 1 to 15
Direct image inputs: 1–7 image URLs at 480p, 720p or 1080p
For grok-video, image-to-video can alternatively use a successfully completed grok-image task with a result index from 0 through 5. Do not combine that method with direct image URLs. It selects an existing image, not a previous video to extend.
These APIXO contracts do not expose video-input editing, native video extension or designated first-and-last-frame controls. Multiple image inputs do not establish those capabilities. Check the Grok Video documentation or Grok Imagine Video 1.5 documentation for your route. The specifications above were checked on October 22, 2026.
xAI’s native video extension is a separate operation: its documented source length is 2–15 seconds, the added portion is 2–10 seconds, and output is capped at 720p. For that operation, duration means seconds added: a ten-second source plus a five-second extension produces fifteen seconds. This differs from requesting the output length of a new APIXO clip. The source-length limit also means you cannot assume that an ever-longer complete video can be resubmitted indefinitely.
Plan a one-minute edit around usable shots
For a product introduction, start with the job each shot must do. The following is an ungenerated storyboard, not a promise of six usable ten-second outputs.
Approximate position: First 10 seconds
Shot purpose: Establish the subject and setting
Connection to the next shot: Leave room for a title or narration
Approximate position: Next 10 seconds
Shot purpose: Show the whole product
Connection to the next shot: Keep light, color and product identity consistent
Approximate position: Next 10 seconds
Shot purpose: Show one detail
Connection to the next shot: Use a close-up instead of forcing a continuous complex move
Approximate position: Next 10 seconds
Shot purpose: Show one use action
Connection to the next shot: Define the starting state, movement and ending
Approximate position: Next 10 seconds
Shot purpose: Show the setting or result
Connection to the next shot: Support the story or narration
Approximate position: Final 10 seconds
Shot purpose: Return to the subject
Connection to the next shot: Add the CTA in editing and check the audio ending
Adjust the timeline to the footage you accept. The grok-video route allows 6–30 seconds per request, so a one-minute edit need not use ten six-second generations. Requested duration and usable duration are different: leave room to trim an unstable opening or ending.
Keep a shared description of the product or character, lighting, palette and framing. Change the action for each shot rather than rewriting every visual detail at once.
Continue from a useful frame
Inspect the previous clip near its ending and export a clear still in your video editor. The literal last frame may already contain blur or distortion. Choose a plausible pose, keep the aspect ratio consistent and describe the action that should happen next.
For this workflow, use the selected still as a single image input and describe the next movement. Treat it as a visual starting reference, not a guarantee of an identical first frame or continuous motion. Additional image slots do not turn another image into a designated ending frame.
An untested prompt example:
The person continues walking to the right at a steady pace.
Keep the camera at the same height and direction, following slowly.
Preserve the clothing, appearance and environment without a cut.
For a small first test on grok-video, request six seconds, its minimum supported duration. Put the previous ending and next opening on the same timeline before producing another continuation.
Check at the join: Subject position, shape and clothing
If it changes unexpectedly: Try a clearer source frame or reject the shot
Check at the join: Movement direction and camera height
If it changes unexpectedly: Describe the next movement explicitly and review both sides of the cut
Check at the join: Speed, light and color
If it changes unexpectedly: Compare moving clips rather than judging only from stills
Check at the join: Sound or speech, when present
If it changes unexpectedly: Review the audio track separately; do not assume voice or timing continuity
A cutaway can make an edit less noticeable, but it cannot repair an incorrect product shape or a deformed subject.
Review picture, sound and total cost
Watch the complete sequence at normal speed. Check whether each shot contributes to the story, then inspect the joins more closely. If the clips contain dialogue, compare voice identity, speaker assignment and lip synchronization. Replacement narration can unify a soundtrack, but it does not establish that the original lip movement matches it.
The public APIXO Grok schemas do not expose an audio toggle or guarantee particular audio behavior. Treat sound as something to inspect in the result rather than promising it in the storyboard.
Record all attempts, their costs and the footage you keep. Consult APIXO API Pricing for API usage rates; Studio monthly credits are a separate allowance. A cheap successful generation can still be poor value if none of it fits the edit.
Start with two adjoining shots
Use the image-to-video starter guide if the source still needs preparation. Then open Grok Video to create the next clip and review the two shots together. Keep the continuation only if it fits the sequence; otherwise, plan a deliberate cut.
Can I request a 60-second video from APIXO’s Grok Video route?
No. The published grok-video duration range is 6–30 seconds per request. A one-minute edit needs multiple clips or other footage on an editing timeline.
