It’s all done simultaneously! Unlike traditional editing where you manually line up clips, Promptus uses the LTX-2 model to generate motion and native-sounding AI voiceovers at the exact same time. This ensures expressive lip sync and visual pacing that feels intentional right out of the box.
While other tools require external mics or recording sessions, Promptus lets you go from script to polished video in minutes with zero recording required. Plus, our ComfyUI integration ensures professional-grade fidelity with a simple, user-friendly interface.
Each generation uses a set amount of credits from your balance, which you can track directly in the template header. Since you're getting a finished, 8-second clip with high-quality video and audio in one click, it provides massive value by cutting out expensive production and editing costs.
Just upload a high-quality static image and paste your script into the "Clip text encode" box. For the best lip sync, use an image with a clear face. You can then adjust the tone, speed, and emotional weight of the audio to match your brand's vibe perfectly.
Absolutely! Every template has a unique Share Link at the bottom of the generation panel. If you’ve dialed in the perfect narration and visual style, just copy the link to share your exact setup with your team or community.
