The Complete Guide to Optimizing Audio Synchronization Effects
For Veo3.bot's audio synchronization feature, follow this three-step process to achieve professional-grade results:
I. Basic setup
- Forces use of Veo 3 models (Veo 2 does not support lip sync)
- The cue needs to include a voice description (example: "Say 'Welcome to the new product launch' in a low male voice")
- Add an indication of ambient sound (e.g., "typing keyboard sounds in the background, volume 30%")
II. Fine control techniques
- Synchronized Lip Enhancement: Add "[lip_sync_accuracy=high]" parameter to the end of the prompt (API exclusive)
- Speech tempo control::
Suggested 120-150 words per 8 seconds of video in Chinese, 90-110 words in English, can be adjusted by "speech_rate=" parameter. - multi-track taping::
Separate different audio sources with vertical lines (e.g., "Off-screen: new product launch | Ambient: office conversations")
III. Troubleshooting
When there is a sound and picture desynchronization:
- Check network latency, 5GHz WiFi recommended
- Reducing contradictory instructions in cue words (avoiding the simultaneous requirement for fast speech and detailed narration)
- For professional projects, it is recommended to use Premiere's Auto-Match feature to fine-tune the project after generation.
