Merge videos into one MP4
Choose the opening shot, put the rest in sequence and export them as one video. The first clip sets the shape of the picture. Your footage stays in your browser, and the finished file has no watermark.
Put your clips in order
Try the two sample shots or choose files from your device. Choosing your own clips replaces the samples.
- 1. Label discussion
- 2. Print swatches
Use this shot order in AI Studio
The brief carries the filenames in the order above. Upload the clips in Studio and review the brief before sending. AI editing requires a subscription.
Watch and listen across the join
In the sample, the speaker chooses a green label for print. Four seconds in, the video cuts to a silent shot of the swatches. Listen just after the cut. The dialogue should have finished, and the last two seconds should be silent. Reverse the shot order to open on the swatches and bring the speaker in at two seconds.

Joining a portrait clip to a landscape clip
The opening clip sets the output aspect ratio. A narrower shot keeps its full picture with space at the sides. A wider shot can have space above and below. Put the clip that matches your destination first, or plan a reframe if every shot needs to fill the frame.
Should the voice stop at the cut?
Joining clips plays their sound in sequence. If the speaker should continue under a new image, use a cutaway instead. In our B-roll workflow the swatches appear while the original speech continues. For a simple join, trim an unwanted pause before assembling the sequence.
Files and export settings
Combine 2–12 clips up to two minutes total. Each file needs one decodable video track and can have one audio track. The MP4 uses H.264 picture with the original frame timing, scaled to fit within 1920 pixels on the longest side. Each clip follows its picture duration. Sound is rendered as 48 kHz stereo PCM when any clip has audio. A sequence of silent videos has no audio track.
Desktop Chrome or Edge with H.264 encoding support can run the export. Open the finished MP4 in your destination player before delivery. To add captions after joining, time them to the merged edit and burn the finished SRT into the picture.
