Which AI video tool for which job: a decision guide (Wan 3.0, Pavo AI, Rea Video)

Most AI video tool articles list ten options and rank none of them. This one is a decision guide: three tools, the exact job each one is wrong for, and the two-line test I use to pick.

The test I actually run

Two questions, in order:

  1. Do I already have a reference? If yes, stop — you want re-shooting, not generation.
  2. Is this one shot or a sequence? One shot goes to a generator; a sequence needs an editor and a dubbing step.

That splits the work cleanly. All three tools below are browser-based, none needs an install, and none of them is a general-purpose NLE.

One shot, camera move is the point: Wan 3.0

Wan 3.0 does text-to-video and image-to-video with motion presets. The presets are the product: a slow push-in versus a handheld drift changes the read of a clip more than any prompt tweak.

Wrong for: anything longer than a few shots. There is no timeline to speak of, and that is fine.

A sequence that needs editing and dubbing: Pavo AI

Pavo AI is the one I keep open for real work, because generation, timeline editing, captions and multilingual dubbing live in the same tab. The feature that decided it for me was character consistency: lock the reference frame once, and shot three still looks like shot one.

The loop:

  1. Storyboard six shots as text.
  2. Generate each with a locked character reference.
  3. Cut the sequence.
  4. Dub last, never before the cut is locked.
  5. Export 9:16 and 16:9 from the same timeline.

Wrong for: a single 5s clip. You will spend more time in the timeline than generating.

An existing clip needs a variant: Rea Video

Rea Video is reference-driven. Give it a clip you like, describe the new subject, and it re-creates the shot with your subject in it.

Wrong for: original creative. It is a re-shooter, not a brainstorm.

The table

Situation Tool Why
One shot, specific camera move Wan 3.0 motion presets, no timeline overhead
Sequence, needs edit + dub Pavo AI generation, editing and dubbing in one tab
Have a reference clip Rea Video re-shoots instead of generating from scratch

The thing that matters more than the tool

Write the shot list first. Every one of these produces better output from a concrete shot description than from a mood word. The tool choice matters less than whether the input is a shot description.
