How long can the generated talking-head video be?

There is a length limit for a single generation, but Mobbi can intelligently split the script into sections, generate multiple video segments, and then automatically stitch them together with smooth crossfade transitions into one complete video. After stitching, the presenter’s appearance, voice, and tone remain highly consistent, creating a seamless long-form video suitable for everything from short clips to mid-length content.

Does the video support both Chinese and English voiceovers?

Yes, multiple languages are supported. You can specify the language in your request, such as Mandarin, Cantonese, or English. Mobbi will choose a matching voice and speaking speed for that language, and automatically generate subtitles in the same language to keep the script, subtitles, and voice fully aligned for different markets and audiences.

If I upload a reference video, how will Mobbi use it?

Mobbi deeply analyzes your reference video and extracts key elements such as the presenter’s appearance, composition style, camera language, and video length. It then uses those elements to closely match the new video to your target style. If the reference video includes a specific person, Mobbi can also capture key frames as appearance references so the final result aligns closely with your expectations.

Can I add background music to the generated video?

Yes. Based on the video’s content style and overall mood, Mobbi can automatically generate background music with a matching duration and blend it into the final video. The music volume is intelligently balanced so the spoken script always stays clear, while the background track enhances the atmosphere without distracting viewers from the message.

你可能还想了解

Absolutely. You only need to describe the presenter you want, such as age, gender, outfit, and overall style or vibe, and Mobbi will automatically generate a highly realistic presenter portrait. Once you approve it, that image becomes the first frame of the video, keeping the presenter’s appearance consistent throughout the entire video with no real person required.
