There are many software solutions that allow you to change the audio pitch and save the file with a new key value. However, if you have a video file and need to change its pitch, you will find very few reliable tools available.
Fortunately, a new solution is now available for video enthusiasts, packed with many useful features. We are talking about VIDEO MIX, a software designed to mix video files, which also allows you to modify fundamental parameters such as PITCH, VOLUME, and TEMPO.
The program is very easy to use. Below you can find the steps to change and save the video pitch (key) in just a few clicks.
How to Change and Save the Video Pitch with Video Mix
Step 1. Download and install the free trial version of Video Mix on your Windows PC or macOS.
The free demo version will add a watermark on the output video. Click here to request the full version without watermark limitation.
The main screen of the software is:

Step 2. Add the video to edit
Click on “Add Video Files” button to load yuor video file (avi, mp4, mov, mkv, mpg).

For each video added, you will see a thumbnail on the left and an audio waveform on the right. Below the waveform you can find some parameters like fade-in / fade-out, crossfade, volume, tempo and PITCH.
Step 3. Change the video pitch
To change key/pitch (from -12 to +12 semiton) you just need to move its cursor (as you can see from the image below)

In the same way you can change Volume and Tempo of the video file.
Before save and export the edited video you can preview the “new” video clicking on the image preview on the left (it will open a new window for preview).
Step 4. Choose the output video format
Go on the Options menu and set the output directory, the output resolution, the output format (mp4 is the default) and the framerate.

Step 5. Export the video with the new PITCH
Finally back to the main window and click on the bottom right button “Export and Save Video” to export the output video. It will take some time to create the final video with the new pitch/key value. That’s all!
VideoMix is available for both Windows and macOS, offering the same powerful features on both platforms.
