A voiceover, or VO, is a type of post-production audio recording where an unseen speaker reads a written script while the video plays. It is a common technique in videos used for educational, informative, or commercial purposes. Voiceovers are often used by narrators or subject experts to provide additional context and information, as well as to express thoughts that cannot be captured on camera.
A good VO is one that sounds natural and authentic. It is important to practice in advance to ensure that the script is understood and easily interpreted by the audience. It is also important to consider the pacing and tone of the voice and make adjustments as needed. It is important to avoid sounding too robotic or droning, as this can be off-putting for the audience. Pronunciation is another important consideration, as it can be easy to slip up and mispronounce words or enunciate them incorrectly. Finally, it is important to consider the facial expressions that will be conveyed by the voice and to make sure these are appropriate for the video content.
It is best to record the voiceover while the video is playing, if possible. This will allow you to keep the pace of your speech synchronized with the action on screen. It is also a good idea to leave some extended silence at the beginning and end of your recording to help trim it down and match it up with your video clip later on.How to do do voiceovers
