Make a rap video with your own song
Use an audio-driven lip-sync workflow when your existing recording must control the mouth movement. A general photo-animation model cannot guarantee the same timing.
Watch the matching example
Prepare an intelligible vocal excerpt
Choose a short section with a clear lead voice and a strong beginning and ending. Heavy reverb, overlapping ad-libs and a beat louder than the vocal make timing harder to judge. Keep the original mix and a separate vocal stem if you have one. Do not assume that removing the instruments is required by every provider; check the selected model’s instructions.
Match the portrait to the voice
Use a front-facing or gently angled portrait with an unobstructed mouth. Choose one performer for a single vocal track. Multiple simultaneous speakers need a model that explicitly supports that setup. Kie InfiniteTalk documents image and audio inputs, but its accepted formats, duration and file limits are model-specific and may change.
Check syllables rather than musical energy
Listen for plosives, sustained vowels and pauses while watching the lips at normal speed. A head nod on every kick drum can feel musical without matching any words. Review the exported clip with sound, then compare its final frame with the end of the audio. The local form validates audio selection without uploading it; live audio-driven rendering remains gated.
Prepare the right inputs
One portrait and a short original vocal recording. Use a clean lead vocal with limited overlapping ad-libs. Choose the corresponding workflow from the template page, and check the input labels before selecting files. A workflow that needs a vocal cannot be validated with two photos alone. If the form reports a file problem, fix that file before continuing. The local preparation step does not transfer selected files to a third-party provider.
Keep acceptance separate from preparation
After a real render is available, inspect the full output, listen to the audio and test the downloaded file on a phone. Keep the task ID and selected settings for troubleshooting. Rendering, payment, download and publishing are separate outcomes; one does not establish the others. Do not repeatedly retry a paid request without checking whether the previous task was accepted.
Performance direction
Match facial articulation to the supplied vocal, preserving pauses and identity. Do not invent another performer.
Troubleshooting
Use a clean lead vocal with limited overlapping ad-libs.
Frequently asked questions
What files does this workflow need?
One portrait and a short original vocal recording.
Does the local form create a finished video?
No. You can prepare the required inputs locally. The model or rendering pipeline for this workflow must be configured and verified before live generation.
Can I use a popular song or another brand’s assets?
A template does not grant permission to use a recording, voice, likeness, character or logo. Use original assets or obtain the appropriate permission.
Model reference: Kie InfiniteTalk documentation. Check current limits before choosing a service.
