If you experience poor translation quality, first check your source audio: ensure speech is clear, volume is consistent, and background noise is minimal. Audio sync issues often stem from videos where the speaker's face isn't consistently visible or lighting conditions are poor. Try re-uploading with better source material or pre-process your video to improve audio quality. If specific languages produce inconsistent results, verify you've selected the correct regional dialect—using Spanish (Mexico) instead of Spanish (Spain) can make a significant difference in accuracy. For persistent issues, test with a shorter clip first to identify the problem before processing the full video. If translation quality remains below expectations, consider the
HeyGen Video Translator V2 Precision model for higher accuracy on critical content.
