Description
Use this app to replace the single audio track in a video file with a new selected file without recompressing the video or audio. It just adds a new wrapper for the existing video and new chosen audio track. Make sure you are choosing an an audio file type that is compatible with the file format you are replacing. The new file will default to whichever file is longer in duration.
