Step 2. Preview video

The built-in video player can be found at the top right section. You can preview the video with the background music. Note that since this process may consume a lot of system resources, previewing video might encounter some audio sync issue, but the final result video file should not be affected.

Step 3. Export video

The final step is to choose a video format and export video to your computer hard drive. Click Export button from the middle toolbar. Then choose the target video format, like WMV, MP4, AVI, MOV, FLV, MKV, TS, 3GP, MPEG3, WEBM, GIF, etc. Optionally customize the video profile, such as video quality, video codec, video resolution, video frame rate, video bit rate, audio codec, audio channel, audio bit rate and so on. Finally hit the Export button to save the video to your computer. The new video will be exported to the output folder of this media editor software.
