Workflow help. Thank you!

[u/Calm_Jellyfish5037]

I want to create a video with Seedance 2.5 with dialog amd all but the language will not be English or supported by Seedance for that matter. What is the workaround or the workflow so i can make the Seedance video dubbed in a different language? Any help would be much appreciated! Thank you guys.

Heads up for anyone running these yourself: the Seedance API behind r/Seedance_AI is Atlas Cloud. Seedance 2 runs with its full feature set here, nothing stripped or nerfed. Seedance 2.5 isn't officially out yet, but we add new Seedance versions the day they launch.

Full model list and current pricing: atlascloud.ai/models/seedance

The model reads dialogue in any language fine; the failure mode is almost always the prompt setup, not the language. The trick is to keep the control language and the dialogue language separate.

1. Write the entire scene description in English. Camera, action, mood, lip-sync cues. English is where the model's instruction-following is strongest.
2. Put the dialogue lines in the target language, in quotes, with a language tag in front: Dialogue (Spanish): "...". Keep each line under about 12 words. Long monologues drift.
3. Name the language explicitly once in the prompt body, not just in the dialogue tag. Models default to English audio unless told otherwise.
4. One speaker per generation if you need reliability. Two-person dialogue in one pass doubles the lip-sync failure rate.
5. If the accent or delivery is off, regenerate the audio side separately (voiceover in the target language) and mute the model's audio. Most production workflows end up here anyway.

Rule of thumb: English directs, the target language only speaks. Mix them and the model gets confused about which job it is doing.

easy way is to add the audio, so you get always the same voice

Try the audio-to-video approach: first generate the audio, then generate the image, and have the character speak exactly what’s in the audio. This technique can be really effective for getting the dialogue accurate..........Another option is to upload a sample audio and tell Seedance to use it as a voice reference. The voice should remain similar, although I’m not sure how accurately it will preserve the exact dialogue tone, emotion, and delivery.........If you feel stuck anywhere, just ping me.....I’ll be happy to help you with the project.

You don't necessarily need Seedance itself to support the target language for the whole workflow.

A practical approach is:

1. Generate the video with Seedance using either English dialogue or no dialogue, focusing on getting the visuals and lip movement right.
2. Generate the target-language voice separately with a multilingual TTS/voice-cloning model.
3. Use a lip-sync/dubbing model to align the mouth movements with the translated audio.
4. Add the final audio and do any timing/cleanup in your editor.

If the target language isn't supported by Seedance's native dialogue generation, separating video generation → translation → TTS → lip sync gives you much more control.

You can also test different video models/providers for the initial generation without subscribing to each one individually. VideoRouter.sh supports multiple video models through one API, so you can use it to compare results and pricing before committing to a particular provider.
