OpenArt Try it →Watch full video →AI Video School · Nov 2025

Demo summary

The video demonstrates using the WAN 2.5 and Google Veo models within OpenArt to generate video clips that include synchronized AI-generated dialogue.

Step-by-step

Navigate to the Video section and select Image to Video
Choose a model that supports audio, such as WAN 2.1 or Google Veo 3
Upload a start frame and, if using Veo 3, an end frame
Set the camera motion settings, such as subtle handheld
Enter a text prompt for the dialogue
Click generate to create the lip-synced video

Options

Use WAN 2.1 for a more cost-effective generation
Use Google Veo 3 for start-to-end frame transitions with audio
Apply different camera motion presets

Watch out for

Generating with Google Veo 3 requires more credits than other models
Using all caps in the dialogue prompt can cause the AI to mispronounce words (e.g., 'YOU' becoming 'yo you')

Tips

Use a consistent voice prompt across multiple videos to maintain character voice consistency
Plan out all shots in advance to manage credit usage effectively
Use start and end frames to better control character movement, such as walking into a room and pausing

Highlights

“It's pretty good.”
