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.

VideoMux Pro works with all key video and audio formats.

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.
