Operation UI design

PowerDirector offers users two editing modes: horizontal and vertical, allowing them to switch effortlessly by simply rotating their phone.

When designing the UI interface, utmost consideration is given to both operation modes to ensure consistency and deliver an exceptional user experience. This entails maintaining consistent instructions and controls during mode transitions, enabling users to seamlessly switch between horizontal and vertical editing. The UI design facilitates a smooth and intuitive experience, empowering users to effortlessly adapt to different modes and maximize their editing capabilities.

Keep product feature UI updating

In mobile app development, it's important to consider both the app page flowchart and UI design. The flowchart provides a visual representation of how different pages and features are connected and enables designers to plan a user's journey through the app. This structure is critical for ensuring that the user experience is smooth and intuitive, leading users to their intended destination through a logical sequence of steps.


When implementing UI design for new features, we must audit and update the flowchart to ensure that it reflects the changes accurately. By examining the location of each function in the flowchart, designers can verify that the user experience remains seamless and that the operation process is efficient.

Optimized launcher and main UI design

Application launchers are crucial for mobile app development, as they serve as the user's first point of contact with the app and set the tone for the entire user experience. A well-designed launcher can help users navigate the app quickly and efficiently, providing easy access to frequently used features and functions, which can lead to increased user engagement and retention. Therefore, it's important to continuously optimize and update the launcher to ensure that users have the best possible experience.

Start optimizing PowerDirector Launcher

In order to let users edit videos easily and quickly with one hand, and also refer to popular softwares which are easy to use, we decided to redesign the launcher including main UI design, and refine the user flow which provided a new operation mode - vertical screen mode, to let the users switch between two modes easier.


Meanwhile, we planned to interact more with users, so we added our social media platform on the new launcher and added more cool demos and video tutorials for more interaction with our users.

Here shows the original version >>>

Refinement items and New launcher for Portrait mode

  • Provide a new Portrait mode launcher, so that users can easily use PowerDirector App with one hand and without rotating their phone.

  • Rearrange launcher layout, refine UI flow, and highlight the “new project button” which user frequently use according to the user data, to let users see it when they open the App.

  • Added tutorial videos to show how to do cool demos.

  • Added social media element info and cool demos on it.

New launcher of portrait mode

The new launcher design should support both landscape and portrait modes, allowing users to switch between two modes by turning their smartphone.

New Main UI design for Portrait mode

  • For the new portrait mode, we hope that users can learn and use it easily, so we re-examined the operation process of the original landscape mode, optimized and re-planned some functional items, and also redesigned the main UI to have consistency between landscape and portrait mode.

  • Added “+" button to let users into the main UI, they will notice it at first glance, and also add text descriptions to let users clearly know that the first step is to add their own video for editing.

Design style for PowerDirector Mobile

App UI design style is critical for creating a positive user experience in mobile app development. It sets the tone for the entire app and influences how users interact with it. A well-designed UI style can make an app more engaging, intuitive, and visually appealing, which can lead to increased user satisfaction and loyalty. In addition, a consistent UI design style across all screens and functions of an app can improve usability and reduce confusion for users. 


Keep optimizing UI design for each new features release

Creating a successful mobile application requires continuous refinement and improvement of its functionality to provide a better user experience. This involves gathering user feedback and analyzing usage data to identify pain points and areas for improvement. Once armed with this information, we can prioritize and address critical issues and make incremental changes to enhance the user experience.

By continuously refining the app's functionality, developers can create an app that meets the evolving needs and preferences of its users and stays ahead of the competition. This approach fosters user loyalty and drives engagement, ultimately resulting in the success of the app.


Keep refining features to find better user experience for PowerDirector App


Add Video clips process optimizing

Optimize select videos / photos flow

1. Users can't distinguish the order of all selected when   

    adding multi-selected video clips to the timeline.

2. Users cannot first preview demo sample when

    selecting video clip materials.

The process of adding clips to timeline


Tap "+ New Project" button


Select more than one material that you want, and press the "Next" button to start editing.


The selected and edited video clips are added to the timeline.

Issue: In the original process of selecting video, when users selected multiple videos, user cannot easily change the order when selected, and can only move to the next stage and shuffle the clips on the timeline, so it’s not user friendly. Moreover, user cannot preview the video clips which they want to choose, but can only watch in static thumbnails, which is very inconvenient for users either.

Refine the flow of selecting video clips material


In order to let users clearly know the order of selected video clips, we added an area of selected video clips. When user clicks and select the video clips, the materials will show the selected numbers and also added to the below area in sequence.


Added preview and enlarge functions, users can click on the enlarge icon on the upper right corner to preview the video clips in full screen, or press and hold the video and preview it, if users want to add it to the editing list, they can easily press “select +”, if not, just click blank space to back to the “add media” page.

Issue: If users select multiple video clips to the timeline, the video track will become very long and it's inconvenient for users to drag and shuffle the clips when editing.

In order to make the editing process more easy, each clip will transfer to 1:1 square thumbnail when users press and hold it, so users can drag it more easily when editing. 


Video Filter effect issue

1. Simplify the process of repeatedly open/ close.

2. UX inconsistency.

The original process of using filter effect


Click the "Filter" and select any filter pack, and press the thumbnail cover and all filters of the pack will pop up.

Press the filter which you want to apply, and an effect adjustment slider will appear on the top of the Control Panel.

If users want more effects, press the "Get More" button, the interface will switch to the effect library.

Click a filter thumbnail and press "+" to see the preview demo of this filter and can purchase/ subscribe to it.

Issue: All "filter" packs are opened (show) and closed (merge) on the same row. If users choose a lot of "filter" packs at the same time, it is easy to cause level confusion.

Rethink the way of selecting filter packs. Replace the thumbnails that originally represent each filter pack with text descriptions first. And use the upper and lower parts to distinguish different levels, divide the "filter" cover and the corresponding filter template into the upper part and the lower part, and simplify the process between different levels.

Issue:  Some UI issues need to be solved. First, when users click "Get more" button to view more filter packs, ​they cannot distinguish the differences between each filter pack at first glance, but need to click on each pack to go to the second layer to see the preview sample, and the image is too small to see it.

Second, users can only see the thumbnail but not try it on the photos, it’s hard for users to decide to purchase or subscribe to it.

We redesigned the UI layout and optimized the user process of the filter effect library.

We've deleted the subscription pop-up window. If users want to click and download the filter, once they click the "download" button, it will change to the "use" button so that users can apply and try it directly, and so can enhance user's interests to filter effects. Users will be notified to pay or subscribe if they want to output their creations.

Refinement UI flow for using filter effect

Press the "tab" option in the upper half to switch different filter packs, and can find corresponding filter effects.

Find the filter pack you want and press "download" button. After completing the download, the button will change to "use", then press it and will directly add to the filter menu, which allows users to try.

Keep adding new feature for each new version release

To keep mobile app users engaged and ensure its longevity, it's important to regularly add and release new features while keeping up with trends and user needs. Each new feature has the potential to boost engagement and user retention, making it more likely for users to continue using and recommending the app. Consistency and intuitiveness in the UI design are also crucial to help users easily adopt new features without feeling overwhelmed. Ultimately, a UI design that continually adds new features with each new release is vital for staying competitive in the ever-evolving world of mobile applications.
