Clips, avatars, and edits

AI video tools

Use this page when the output is a clip, a talking-head video, or an edit with generative effects. A good fit is the kind of video, the price shape, and whether the product is offered in mainland China.

Runway is the short-clip studio with mainland China access not confirmed. HeyGen is the talking-head and dubbing listing, also not confirmed. 可灵, 海螺 AI, 即梦, and 剪映 are marked offered in mainland China.

Every card has a free tier in the index. Clip length and watermarks are not fields we store.

How to choose

  • Split generation from editing. Runway, 可灵, 海螺, and 即梦 are generators in their listings. CapCut / 剪映 is an editor with generative effects. HeyGen is talking-head, avatars, and translated dubs.
  • Read the China mark with the job. Four of these six are marked offered in mainland China. Runway and HeyGen are not confirmed.
  • Use 即梦 or 可灵 when you also need still images from the same product. Their listings cover both.
  • Use HeyGen when the subject is a person speaking to camera or a translated voice. Use Runway when the listing you want is short-clip generation and editing.
  • Plan on a paid plan if the free credits run out. The index shows freemium and leaves the credit table on the vendor’s site.

Shortlist

Six listings, all in the video category. The line under the card says which job it matches.

  • AI image generators

    即梦 and 可灵 are also on the image page, with Midjourney and the other still-image listings.

  • AI tools for mainland China

    可灵, 海螺, and 即梦 are on that shortlist. 剪映 is in the video category if you browse the China filter.

  • AI presentation tools

    A deck is a different output. Gamma and ChatGLM are on the presentation page.

Questions

  • Which tools are for a person speaking on camera?

    HeyGen’s listing is talking-head videos, avatars, and translated dubs. The generators on this page (Runway, 可灵, 海螺, 即梦) describe clips or images, and 剪映 describes an editor. Mainland China access for HeyGen is not confirmed.

  • Which video tools are offered in mainland China?

    可灵, 海螺 AI, 即梦, and 剪映 are marked offered. Runway and HeyGen are not confirmed. The mark is a public-offer note from the seed review, reviewed 18 Oct 2026, and companies can change access.

  • Where are clip length and watermark rules?

    They are not fields in this index. Runway’s listing says short clips. It does not publish a second count, a watermark promise, or an export matrix. Those rules live on each vendor’s site.

  • What is the difference between 即梦, 可灵, and 海螺?

    即梦 is ByteDance’s studio for images and video. 可灵 is Kuaishou’s video and image generator. 海螺 AI is MiniMax’s video generator. All three are marked offered in mainland China and are freemium in the index.

  • Is CapCut the same product as 剪映?

    The listing says the international app is CapCut and the mainland China app is 剪映, both from ByteDance, with generative effects in the editor. The index marks that listing offered in mainland China.

Limits

NavBoth is a directory of public products already in the index. These pages help you choose a listing. The product itself runs on the vendor’s site. Mainland China marks come from public offers reviewed with the seed; they are not a live connection test. No listing on these pages has a paid badge. Names belong to their owners.

Length caps, watermarks, voice-consent rules, and export formats are on the vendor’s site. This page records the job each listing already describes.
