Select photos, align them, and export a video.
FrameFlip aligns your selected photos to a single reference image and exports a short MP4 video.
How it works
Select a reference image
First, select a single image to use as the reference (base image).
This image determines the overall size, orientation, and alignment of the video, so choosing an image that is close to a frontal view and has minimal tilt will make the subsequent alignment more stable.
For people, a photo with a clearly visible face works best. For objects, choose an image where the shape is distinct and there is some margin around the subject within the frame.
Select a target (Face / Object)
Next, specify what part of the image should be used as the alignment target.
• Face mode
Faces in the image are automatically detected. If multiple faces are found, tap to select the one you want to use as the reference.
If photos with very different face angles or sizes are mixed, the alignment result may become unstable. Using photos taken under similar conditions is recommended.
• Object mode
Drag a rectangle (ROI) on the screen to specify the part of the object you want to use as the reference.
You do not need to enclose the entire object. Selecting a distinctive, non-moving feature often results in more stable alignment.
Select frame images
Select multiple images to be used in the video.
The order in which the images are selected becomes the playback order, and you can rearrange them by dragging.
When images of the same person or object are taken from similar angles and distances, the passage of time appears more natural in the resulting video.
Preview and export
Check the alignment result in the preview, and if everything looks fine, export it as an MP4 video.
Even if not all frames align perfectly, the app automatically switches to a safe display mode, allowing you to export the video as is.
The finished video can be saved to the Photos app or shared with other apps.
Tips
• Alignment looks off: Similar framing and distance across photos improves stability.
• Video feels heavy: Reduce the number of frames or lower the image resolution.
About & Privacy
Image Recognition and Data Handling
This app analyzes visual features within images on the user’s device in order to align photos and generate videos.
All image analysis is performed entirely on the user’s device, and no images or analysis results are sent to external servers.
Handling of Face Data
When Face mode is used, the app detects faces within images and temporarily analyzes features such as position and size.
These analysis results are used solely for the purpose of image alignment and are discarded once video generation is completed.
Face data—including face images themselves, feature data, or any form of identification information—is not stored or used for any other purpose.
Face data is not shared with any third parties.
Object (Image) Recognition
In Object mode, the app performs alignment using feature points based on the region of the image specified by the user.
This process is also completed entirely on the user’s device, and no images or analysis data are transmitted externally.
Data Storage and Retention Period
The app does not permanently store image data or face data used for image recognition, including face detection.
All such processing is performed on the device, and the data is discarded after the processing is complete.
During video export, temporary video files may be stored on the device to ensure stable processing.
These temporary files are automatically removed when they become older than a certain period, such as during subsequent export operations.
The storage and management of generated videos and user-selected images are handled solely based on the user’s actions and the device’s system settings.
About Ads
The free version may display third-party ads (Google AdMob).
Ads are served as non-personalized by default, and personalized ads using the device advertising identifier may be used only if you allow it. Ads are not shown in Pro.
Open Source Software
This app uses open source software for image processing.
