Frequently asked questions (FAQ)

The app freezes or crashes unexpectedly while I was working on a project. What should I do?

The app freeze/crash issue is usually caused by out of date graphics driver and you need a driver update. You can open Device Manger → Display adapter to see details of your graphics adapter including the adapter's name. After that you can get the latest device driver from its manufacturer's website below:

While saving (exporting) video from a project, I got the error message "Stream is not in a state to handle the request". Sometimes the video can be exported successfully but the audio stream/video stream are out-of-sync. What should I do?

There are a number of reasons that may cause this issue. Please try the followings:

  • Save video again with another Encoder option.
  • Update your graphics driver as instructed here.
  • If your project contains video clips that are not of MP4 format, convert them to MP4 using the Convert Video quick tool then replace the clip in your project with the new MP4 file.

What are the differences between FREE and PRO versions? Why I see them identical?

The FREE app and PRO app are two separated apps. If you install only FREE version or only PRO version on your PC, you will see the differences as described here.
However, if you install both versions on the same computer, all features on the FREE version will be unlocked automatically. In this case, you will see the two apps are nearly identical. You can continue working on the FREE version. However we recommend you to transfer all your projects to the PRO version so you will work with only one app.

I am working on a video project on the FREE app. I decided to purchase the PRO app to use advanced features. What should I do?

Thank you very much. Please follow the steps below.

  • Close the FREE app (DO NOT uninstall the app, and DO NOT create any new project as the new project will overwrite the current autosaved project).
  • Purchase and install the PRO app on the same PC.
  • After the installation is finished, open the PRO app to import the project from the FREE app.
  • See more detailed instruction here.
  • NOTE: Your unsaved project on FREE app will show up as "Latest project from FREE app".

What is the difference between Save video and Save project?

When you are working on a movie project, you will find two buttons at the bottom toolbar: Save video and Save project.

  • Save project is for saving your project so that you can open it and make further editing later. The project will be saved to the app's local folder.
  • Save video is for exporting your current video project to a single video file. You will be able to select the output folder to store the video file. After the exporting process is done, you can play the file with other media players or share the file with your friends.
