Next, we need to add photo, video, music files... used in the video. Click the Browse files button to upload data files.
After uploading, drag and drop the content files to the timeline below and arrange them in the desired order.
To adjust the length of the video, move your mouse to the end of the video, then press and hold and drag back and forth as desired.
After arranging the video content, we proceed to insert more text by clicking the Text button in the left menu. There are many text formats for you to choose from, simply drag and drop them below the timeline to use. At the top of the window there are 3 tool buttons you can use including:
- Text : Change text content
- Transform : Change the text size
- Colors : Change text color
After selecting the text, you can add transition effects using the Overlay button in the left menu. However, these effects are quite simple and few, you should consider using them.
Finally, after completing the video, click the Export button in the upper right corner of the screen to export the video and download it to your device.
