VideoMux Pro allows users to merge (mux) an audio track into an existing video file. It replaces the audio track inside the source video file completely with a new audio stream or mixs the two audio tracks together. You can also delay the video, set a custom size for the frames, pad the frames, crop the frames, apply transform effects to the frames, adjust the volume and the image motion.

The pre-editing function of this software allows you to cut a selected part of the video file or to cut the parts that have no sound. You can also cut a chunk of the source audio and use the amplify function in order to adjust the volume.

VideoMux Pro works with all key video and audio formats.
