Tips for the best result
- Choose "Stacked" for vertical platforms — two 16:9 clips stacked are close to 9:16.
- Use "Mix all" for duets and "Main video" for reactions over music.
- Shorter videos hold their last frame until the main one ends.
Side-by-side — FAQ
Whose sound is used?
By default the first video's sound. Switch to "Mix all" to hear every video at once.
What if the videos have different lengths?
The first video sets the length. Shorter videos hold their last frame until it ends.
What size is the output?
Each cell is the size of the main video, so two 1080p videos side by side make a 3840 × 1080 video (capped at 4K).
Can I use videos of different shapes?
Yes — each video fills its cell and is cropped slightly if its shape differs.
Can I add a caption across both?
Yes, stack "Add text" and it sits on top of the whole frame.
