Kling 4.0 Omni Reference vs Keyframes: Choose the Control Your Shot Needs

A product photograph can explain what an object looks like, or it can define the image you want at a particular moment. Those are different creative instructions. Choosing the right entry point makes the difference easier to communicate.
Kling's user guide distinguishes Omni Reference from Keyframes and says the two entry points cannot be combined in one generation task. Use the illustrative mug example below to prepare the right inputs, assign each file a clear role and plan the moments your video needs. Mode specifications were checked against the official guide on October 23, 2026.
Quick choice: asset roles or timed images?
Use Omni Reference when the inputs explain identity, setting or movement. Use Keyframes when particular pictures need to anchor particular moments. The guide describes images, videos and voice profiles for Omni Reference; the separate Keyframes entry accepts images rather than reference uploads.
Ask yourself which failure would make the clip unusable. If it is the wrong product appearing in an otherwise flexible scene, begin with a clear identity reference. If it is missing the required closing composition, plan the timed images first.
| Planning question | Omni Reference approach | Keyframes approach |
|---|---|---|
| What is fixed? | The mug's identity and the reference roles | The supplied compositions at chosen moments |
| What can vary? | The model's staging within the written brief | The motion connecting the planned images |
| What should I prepare? | A small, clearly explained reference set | Compatible images with a deliberate visual progression |
| What should I review? | Identity, reference leakage and shot usefulness | Arrival at each moment and continuity between them |
1. Prepare one identity source you can trust
Our example product is an ivory mug with a charcoal handle and an amber band. Choose a sharp photograph that shows the entire mug and its contact with the table. Give the file a meaningful name before uploading so you can identify it again in your experiment record.
If the shot needs another side of the object, photograph that side. A second real view answers a geometry question that a mood board cannot. Keep the lighting differences understandable and check that both pictures show the same version of the product.
Write three acceptance details before generating: the charcoal handle remains connected at both ends, the amber band keeps its position, and the mug rests on the surface. These checks belong to this example; choose equivalent identifying details for your own product.
2. In Omni Reference, give each input one job
The user guide uses upload-order identifiers such as @Image1 and @Video1. Match those identifiers to the actual files in your workspace, then state their jobs. Do not paste the sample numbering without checking it.
For this brief, the mug photo defines the object and a separate desk photograph defines the setting. A camera reference, if you use one, should contribute movement rather than introduce another product. Begin with the smallest set that communicates the intended shot.
@Image1 defines the ivory mug, charcoal handle and amber band. @Image2 supplies the pale wood tabletop and soft window lighting; the mug design comes from @Image1. Make a 10-second product film with one continuous shot. Begin at a readable three-quarter view of the whole mug. Move gently closer, keeping the handle and amber band visible. The mug stays resting on the tabletop. Finish with a calm hold on the whole product. Audio: quiet room ambience, no speech, no subtitles, no background music.3. In Keyframes, design a progression the viewer can follow
Prepare the visual milestones before writing elaborate movement directions. Each image should show the same mug in a compatible setting. If the first image puts the handle on the right and the next moves it to the opposite side, decide whether that change is an intentional viewpoint shift or a source mistake.
The ten-second storyboard below gives each image a clear purpose. Set the available timestamps in the interface and describe how the scene moves between them. Use fewer milestones if the action does not need more, then inspect whether the output reaches each composition with a believable transition.
| Planned moment | Image to prepare | Reason for the image |
|---|---|---|
| 0 seconds | Whole mug in a three-quarter tabletop view | Establish the object and its surroundings |
| 4 seconds | A closer compatible view with the handle fully readable | Draw attention to the identifying detail |
| 9 seconds | Whole mug with space around its silhouette | Arrive at a clear closing composition |
The supplied keyframe images show the same mug on the same tabletop. Connect the opening three-quarter view to the closer handle view with a gentle camera move. Ease back toward the wider closing composition and hold it calmly to the end. Keep the mug's material, handle connections and amber band consistent through the transitions. Use restrained movement and soft window light. No subtitles. No background music.4. Budget the references before uploading a large set
The published Omni Reference limits include 15 combined assets, at most 10 images, five videos, seven elements and three voice profiles. Videos, editing clips and video elements also share a five-clip allowance and a combined 30-second limit. The category ceilings do not add up to a larger total allowance.
For the mug brief, there is no need to fill those limits. Keep a simple input ledger with the file name, its role and whether it remains necessary after each revision. If the model borrows the wrong table or product, the ledger helps identify the ambiguous instruction.
5. Review the connection between moments
Watch the complete clip at normal speed, then compare frames near the start, the middle and the closing hold. A sequence can arrive at an attractive final image while the handle deforms on the way there.
Record the failure in concrete terms: the band changes width during the approach, the mug slides during the camera move, or the ending crops the rim. Change the input or instruction most directly connected to that failure before adding more references.
If both routes are plausible, compare short trials against the same acceptance checks. Record differences in their inputs and settings rather than presenting them as an isolated model benchmark. An attractive single result is a useful sample, not a reliability measurement.
Use the planning method across tools, then check the actual controls
Separate identity, timing and motion when planning across video tools. Each interface has its own input labels and supported combinations, so map your brief to the controls offered by the selected model.
Use the Ciyo-specific guide for Ciyo's controls. If you are following the examples here in Kling, keep its user guide open and verify the selected version. Flash does not provide the full model's start-and-last-frame and multiple-keyframe controls in the reviewed documentation.
Mode selection questions
Can I combine both entry points in one generation?
The reviewed Kling user guide says their capabilities cannot be combined in one task. Pick the entry point that communicates the main constraint and check the current interface.
Should I always use the maximum number of keyframes?
Use the visual milestones the story needs. Extra images that disagree about identity or viewpoint can complicate the brief without making the result more useful.
Can I upload background music as a voice reference?
The user guide restricts audio input to voice profiles. It directs creators to describe desired music and sound effects in the prompt.
What should I check between keyframes?
Watch for changes in product shape, handle connections, surface markings and contact with the table. Review the motion between the supplied images as well as the arrival at each planned composition.
Prepare a brief with one clear role per image
Separate product identity, setting and timed compositions before you generate. Keep the original photo and your acceptance checks beside the brief.
