AI digital humans are becoming a high-frequency tool for content creation: enterprises use them for product presentations and training courses, individual bloggers use them for mass production of oral videos, and long online digital human anchors have also appeared in e-commerce live streaming rooms. Compared to traditional video production, digital human videos do not require real people to appear on camera, set design, and repeated re recording, compressing the main cost to the "copywriting" stage. This introductory article will guide you through the basic process and precautions of digital human videos.
Step 1: Clarify the purpose and choose the image
The image of digital humans can be roughly divided into two categories: one is the platform's built-in universal digital humans, which are suitable for quick and low-cost use; The other type is digital humans cloned based on real human images, which require personal authorization and are suitable for scenarios that require "real human IP appearances". When selecting, it is recommended to first generate a test video using the platform's free samples, focusing on observing whether the mouth shape is synchronized with the voice and whether the movements are natural, before deciding whether to pay.
Step 2: Prepare the copy and audio
The core of digital human videos is actually copywriting. First, write a good oral script, paying attention to colloquialism and using short sentences frequently; Then hand over the copy to the voice synthesizer and choose the appropriate tone, pace, and emotion. Many platforms support voice cloning, but cloning someone else's voice requires clear authorization, and commercial use should be cautious to avoid infringement disputes.
Step 3: Generation and Post Production
By combining image, copy, and voice, the platform will automatically generate a digital human broadcast video. After generation, you can continue with post production by adding subtitles, background music, and visual materials, or placing digital characters in the background of a virtual studio. For batch content (such as a daily news broadcast), a "copy template+automatic generation" pipeline can be built to compress the production time of a single video to the minute level.
Compliance and Ethics Reminder
There are two high-frequency compliance issues in making digital human videos. One is the right of portrait: the use of real person images or voice clones must be authorized by the individual. Second, content identification: China's Administrative Provisions on the Deep Synthesis of Internet Information Services, which came into effect on January 10, 2023, requires that content generated using deep synthesis technology should be marked prominently to avoid misleading the public. It is recommended to prominently label "AI generated" in the video, as this is both a compliance requirement and a responsibility to the audience.
Summary
Digital human videos have turned the most expensive aspect of being on camera into a configurable asset. For individual creators, it is a low-cost tool for mass producing oral content; For enterprises, it is a means of standardizing training and marketing content. But no matter how convenient the tools are, the quality of copywriting and compliance awareness remain the watershed for whether digital content can be sustained in the long run.
