- Does this replace the original audio?
- Yes, the new audio file replaces the existing soundtrack entirely. To keep the original audio and mix in additional audio, use our Mix Audio tool instead.
- What if the audio and video are different lengths?
- By default the output length matches the shorter track. If your audio is a full song and the video is shorter, enable 'Loop Video to Match Audio' to repeat the video until the song ends.
- Can I add a voiceover to a video?
- Yes. Record your voiceover as an MP3 or WAV, upload it as the audio file, and the tool will replace the video's soundtrack with your recording.
