Decision factors for video localization

Choose the workflow that fits the source footage

You shot the video. You want to keep it.

Both platforms can support existing-video dubbing. Test the footage, desired performance treatment, and review process before choosing.

Validate languages, runtime, and plan

Long-form, not just clips.

Confirm duration, credits, lip-sync needs, and review requirements against the team’s actual plan and source footage.

Consider the broader content need

Built for premium and agency-grade creative.

Synthesia also supports broader AI video creation, including avatars and script-to-video tools. LipDub focuses on video localization workflows.

Synthesia is shaped for corporate training. LipDub is shaped for TV-spot review, hero ads, branded courses, and agency client work.

The same talent stays on camera, lips and voice matched, in every language.

The team needs existing-video dubbing alongside broader AI video creation tools.

Consider LipDub when:

The team needs a dedicated workflow for performance-led, live-action footage.

How to choose between LipDub and Synthesia

Choose based on whether you are localizing existing live-action footage or evaluating AI video creation as part of the same project.

Start with the project type

If retaining the original on-camera performance matters, evaluate the localization workflow against the actual footage.

Consider the broader creation need

If avatars or script-to-video are also part of the project, include Synthesia in the evaluation and assess the workflow against the planned content mix.
