01
Open Interleave in Process
Open Process, then tap Interleave.
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
Add videos A and B
The main source appears as A Current Video. Tap Add Video and choose B from downloads, Photos, or Files. In Photos, select the video and confirm with the top-right checkmark.
Added count versus total count
1 added, 2 videos total means one additional video plus the main source. A is the main video and its lock control cannot be used. Sorting and removal controls beside additional videos depend on their positions and counts.
The example sources
A is about six seconds; B is about 2:26. Large differences in source length can produce very different segment durations. Trim sources to similar lengths first if you want more even switching.
04
Set the interleaving rules
The example uses Total Segments, 5 segments, Start with A, and the default 50 ms audio fade. Read the distribution explanation at the bottom.
Total Segments versus Fixed Duration*
With five total segments, A receives three segments of about two seconds each; B receives two of about 1:13 each. They alternate. Fixed Duration is a VIP option for time-based splitting.
Start Order
Start with A begins with the main source; Start with B begins with B. Reread the distribution summary after changing it.
Audio Fade
The default fade of about 50 ms softens each audio cut. The page describes free support for two videos, up to five segments, and the default fade. More sources, fixed duration, and custom fades require VIP.
05
Check the result, then save or keep processing
Tap Start Processing, then play through the transitions. Check which source comes first, the segment order, and the sound at each cut.
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 switching rhythm is uneven
Total Segments does not guarantee equally long cuts from every source. The example sources have different lengths, and the interface shows different per-segment durations.
Frequently asked questions
How is it different from Stitch Videos?
Stitch Videos joins complete clips in sequence. Interleave alternates segments from different sources.
Why can the default Total Segments work despite its star?
Up to five total segments are free. Check the selected value and the access notes together; a star on the control does not mean every value requires VIP.
