Merge Videos

Different phones, different sizes

Clips from different phones and apps often have different sizes, frame rates and audio. Simply sticking them together usually fails or plays wrongly. This tool makes them match first:

• The output size is the first clip's size (capped at 1080p). Other clips are fitted inside with black bars, never stretched.
• Everything is converted to 30 frames per second and standard MP4 (H.264 + AAC).
• Clips without sound get silence for their length, so the audio never drifts out of step.

Order and length

Clips play in the order you select them, so pick the first clip first. Up to 10 clips and 3 hours in total. Merging re-encodes the video, which takes roughly as long as the total length for large files. To cut parts out first, use Trim Video. To add background music to the result, use Add Audio to Video.
