01
Open Segment Grid in Process
Open Process, then tap Segment Grid.
02
Choose the video to process
In Select Video, tap Choose from Photos or Choose from Files and select your video. You can import a video even when the download list is empty.
03
Set rows, columns, and sound
After importing one video, inspect Columns, Rows, and Sound. The example uses two columns, two rows, and default mute.
Rows × columns determines the tile count
2×2 creates four tiles and divides the source into four equal time segments. They play simultaneously, so the result is shorter. The displayed estimate may differ from the actual output.
Mute and First Segment Audio
Mute avoids overlapping audio. First Segment Audio uses the first segment’s sound; check whether it suits the whole grid.
Free settings and starred options
Start with the free 2×2 grid and Original Video Size. Three or more rows or columns, square output, and preserving each tile’s original size require VIP.
04
Choose the output dimensions
Open Export Size. This controls the whole output canvas, not the dimensions of one tile.
Original Video Size versus original size per tile
Original Video Size is 640×338 here, shared by all four tiles. Keep Each Tile Original Size shows 1280×676*. It preserves more pixels per tile and may substantially increase file size and processing time, subject to system limits.
Landscape, portrait, and square
The list also offers 1280×720, 1920×1080, 1080×1920, and 1080×1080*. Choose for your intended display and check each tile for clarity and cropping.
05
Check the result, then save or keep processing
Tap Start Processing, then preview the grid. Check that each tile shows the intended segment and that the output size and sound suit your use.
Preview and save
Play the result and check picture, duration, and sound, then tap Save to Photos. The first save may require permission to add photos and videos. After the success message, check the file in Photos.
What the other buttons do
Keep Processing takes the result into tool selection. Share File opens sharing options. Done closes the result page; it does not save to Photos.
Troubleshooting
The tiles are too small to see clearly
At a fixed output size, more tiles leave fewer pixels for each. Reduce the rows and columns or choose appropriate final dimensions.
Frequently asked questions
Does this combine several separate video files?
This tool uses different time segments of one video. It does not show the additional-source list used by Stitch Videos.
Why is the default output silent?
Mute is selected by default to avoid overlapping audio. Choose First Segment Audio if appropriate.
