Choosing Vidu image to video vs reference to video starts with the role of your picture. Image to Video uses a starting composition; Reference to Video uses images to guide a recurring subject. Use endpoints when the opening or ending must be planned, and subject references when the same design needs to appear in different shots.
Give each image a job
Consider an original illustration of a red delivery bicycle outside a bakery. You may want the wheel to turn in that exact composition, a transition to the bicycle farther along the street, or a series of new scenes featuring the same bicycle. These are three briefs, even if they all begin with the same file.
Treat endpoints as compositions and references as design information. The table below applies that distinction to one project; these are jobs you assign to your files, not four separate Vidu upload modes.
| Image role | What it tells the project | Example with the bicycle |
|---|---|---|
| First frame | Where the shot begins | The exact bakery composition |
| Last frame | Where the transition should arrive | The bicycle farther along the same street |
| Object reference | What a recurring object should look like | Clear views of the red frame and front basket |
| Setting reference | What environment should be represented | A separate bakery exterior image |
The distinction is about the input’s purpose, not a guarantee of output fidelity. A reference is guidance to evaluate against, not proof that every component will remain identical.
Set up Vidu AI image to video
Follow Vidu’s documented image-to-video setup:
- Open Try Vidu and choose Image to Video.
- Upload the starting image. Add an ending image only if the destination composition matters.
- Describe the movement in the prompt. Review duration, resolution and movement strength; Amount controls how many outputs you request.
- Click Create when the setup is ready. Vidu’s image-to-video workflow page then directs you to preview and download the completed result.
For a simple shot, start with the image-to-video route. In the bicycle example, a small wheel movement is easier to specify and assess than a full journey through an unseen city. An original instruction might be: “The bicycle rolls slowly to the right while the camera holds the bakery in view.”
Examine the starting image before submitting. Is the entire bicycle visible? Does the wheel overlap a foreground object? Is there room to move in the requested direction? If the bike fills the frame, moving it sideways may quickly remove the very object you want viewers to see.
Keep the first attempt focused on one motion. Inspect whether the basket, wheels and frame retain an acceptable relationship. If the model moves the camera instead of the bicycle, revise that particular instruction. If the bike’s shape changes around an obscured wheel, reconsider the source rather than simply lengthening the prompt.
The public instructions do not give a complete model-by-model settings table. Check what your selected mode actually offers and the displayed cost before submitting. Do not copy a duration or resolution from an unrelated tutorial and assume it applies to this setup.
Use an end frame to define a destination
An end frame is most useful when reaching a specific composition is part of success. Prepare it intentionally. Do not use an unrelated attractive bicycle picture merely because the tool accepts another image.
Compare the endpoints for object shape, scale, lighting and viewpoint. If the opening shows a side view and the ending shows the bike head-on, you have introduced a substantial turn or camera move. That can be the intended transition, but it should not arrive as a surprise after generation.
Write a short bridge description in ordinary language. “The bike continues down the same street toward the next doorway” explains a relationship. “Make an amazing cinematic transition” leaves that relationship unresolved.
For precise product imagery, decide which details are mandatory. A mood video can tolerate different incidental reflections. A product demonstration may require the basket attachment and wheel design to remain faithful. Set that acceptance bar before selecting the most attractive result.
Build references for a repeated subject
Vidu’s Reference to Video instructions describe this separate route:
- Open Try Vidu, then choose Reference to Video.
- Add one to seven reference images from your own files or Vidu’s reference library.
- Describe the action. Select the available resolution, aspect ratio and other output options.
- Click Create, wait for completion, then preview and download.
The page also discusses references from videos, but its numbered upload instructions specify images. This walkthrough follows those image instructions. It does not establish video-upload requirements or which models expose every reference feature.
For the bicycle, assemble a small reference set whose images agree. One unobstructed side view can establish the frame; another can clarify the basket. A separate environment image can describe the bakery. Avoid mixing two versions of the bike and asking the model to decide which details are authoritative.
| Reference problem | Why the brief is ambiguous | Better preparation |
|---|---|---|
| Two images show different baskets | The recurring object has competing definitions | Choose the intended version |
| The useful detail occupies a tiny corner | The reference’s purpose is unclear | Prepare a clearer view of that detail |
| Every image has a different visual style | Style and identity become entangled | Decide which source governs appearance |
| Several similar objects appear together | It is unclear which one should recur | Isolate the intended subject in the source |
Our recommendation is to use enough references to clarify the subject, then stop. Filling every available slot is not itself a quality strategy. Each added image should resolve a known ambiguity rather than introduce a new one.
Review a sequence as a sequence
A recurring subject can look plausible in each clip while changing visibly between clips. Put the proposed sequence on a timeline and compare adjacent shots. For the bicycle, inspect the frame color, basket shape, wheel proportions and direction of travel.
Decide which differences are harmless. A camera angle should change how the object appears; a new basket design is a different issue. A useful review note identifies the property and the shot where it changes, instead of assigning a vague low consistency rating to the entire project.
Retain an approved source set independently of the video outputs. If a generated frame contains an accidental change, do not quietly add it to the references for the next shot. That makes the altered design part of the next brief and obscures where the drift began.
When a transition is difficult, consider whether the story needs it. Two clear shots with a deliberate edit can communicate more reliably than one ambitious continuous movement. That is an editing choice, not a claim that a particular Vidu feature cannot perform the transition.
Vidu image to video vs reference to video: choose by failure
| What did not match the brief? | Reconsider the input role |
|---|---|
| The bike appears in a different starting composition | If the precise opening matters, use that composition as a first frame. |
| A new scene needs the same bike design | Use compatible subject references rather than expecting one starting composition to describe every scene. |
| The ending feels like an unrelated location | Check the end image and explain the intended transition, or remove it. |
| A later shot inherits an earlier defect | Return to the approved reference set instead of reusing the defective output. |
These questions help choose the appropriate workflow. Neither endpoint images nor a reference set establishes that the generated bicycle will remain identical.
Before you call the clip finished
Confirm that the selected result answers the original brief, that its final crop works in the intended format, and that the downloaded file has the expected duration and presentation. Save the approved file alongside the model label, source images, prompt and displayed charge. Reopen the downloaded file in your intended player or editor to check it there too. The documented download step does not establish a particular file format, watermark status or commercial-use entitlement.
The right starting question is simple: do you need to animate this picture, reach another picture, or reuse this subject? That answer determines what evidence each image should provide before you ask Vidu to generate anything.
