Multiple materials enter the same video task
Alibaba Cloud Bailian's Wanxiang 3.0 guide introduces capabilities such as audio video generation, multi-modal reference, video editing and extension. The reference materials can involve pictures, videos, audios, documents or public web pages. There are combination restrictions for different input methods. All types listed on the page cannot be understood as being arbitrarily mixed in the same request.
First decide what the materials describe (ChinaOPC analysis)
When making a short film for a product, the product photo illustrates the appearance, the scene picture illustrates the environment, the document illustrates the information that needs to be expressed, and the reference clip may only illustrate the camera movement. Clearly describing the function of each material will help determine where the generated deviation comes from, and will also make it easier for customers to understand which pictures are based on the data.
A practical storyboard can include the purpose of the shot, the subject's actions, the information that needs to be maintained, the sound requirements and the expected sequence. Even if the model can automatically arrange the shots, the small team should first confirm whether the story holds up: what the audience should understand after watching it, which facts must be accurate, and which parts of the creation are allowed to change.
After generation, you need to look at the screen and information separately.
Acceptance can be divided into four rounds: appearance, action, text and sound. Whether the shape of the product changes, whether the character's movements are reasonable, whether the subtitles are consistent with the confirmed copy, and whether the narration adds unprovided facts, all need to be checked. The usage scenarios supplemented by the model cannot automatically become proof of the real effect of the product.
If only a few shots need to be adjusted in the first round, the approved clips and the parts to be modified should be recorded before deciding to partially modify or regenerate them. Preserving each round of input and output can reduce the need for customers to repeatedly confirm the same details and avoid overwriting already approved documents.
Two specific reminders for interface access
The official guidelines require that the model, calling address and API Key belong to the same region, and state that the video URL that generates the result is valid for 24 hours. Practical applications need to save the result file in a timely manner and check whether the selected model is supported in the region where the account is located; if the page link is returned successfully, it does not mean that the delivery file has been saved for a long time.
Service quotation must include manual work
In addition to model calls, the budget should also include material cleaning, failure retries, subtitle proofreading, sound processing and customer modifications. You can first build a sample around a type of fixed short film, clearly describe the delivery scope, revision rounds, and output specifications, and then decide whether to expand it into a stable service.
