How to Add Audio to Video or Replace Audio in a Video File

By Mar 07,2017 15:14 pm

The audio or music of video can have a dramatic effect on our perception of a video – no matter whether it’s a home movie, a commercial, or a video presentation. But what if all you have is silent footage or with just crackled and distorted audio file that needs to be replaced?

To solve this problem, I humbly recommend Wondershare Filmora (originally Wondershare Video Editor). With it, you can easily add audio to video, or replace the original audio track (stream) with a new audio file or voiceover. Now see the easy steps to add audio to video files or replace the orignal audio track.

Is it possible for me to uninstall/remove some effects (summer, valentine, etc) from my program? For some reason, ever since I downloaded and installed the Summer effects pack, my video and audio do not sync. My music track is longer (4:00) when played on top of video clips in Filmora. But it is 3:56 only when played with VLC, Windows Media Player, my mobile phone, and Filmora without video clips.

Can I add my own narrative? Can I add my own art work ? When Im done can't i just save it to my computer and look at it and re edit it . Why do I have to go directly to "export". Why can't I just save. and upload when Im satisfied it's finished. This is very odd ending with "export".

I record gameplay videos with DxTory where I have one channel for game audio and one channel for mic. How can I use both on the video? I still want it as two different channels as I need to edit only one and not the other
