Upload your MP4 video and audio file to create perfectly synchronized content. Our High Technology Engine Processor (HITEP) ensures studio-quality results every time.
Select an MP4 video (max 50MB for shorts)
Supported: MP4 only • Max size: 50MB
Important: This tool replaces the original audio of your video with the sound you upload. Any existing sounds in the video will be removed and swapped out for your new audio track. This ensures a clean result without overlapping or "double sound." Perfect for creators, video editors, or anyone who wants full control over the soundtrack of their videos.
Select an audio file to merge with your video
Supported: MP3, WAV, AAC, M4A
Important: The uploaded audio should ideally match the video's length. If your audio is longer than the video (e.g., 25s audio for a 20s video), our processor will trim the audio to match the video's duration. If your audio is shorter, the video will end when the audio finishes. For precise results, ensure your audio is pre-edited to the exact length of your video.
