Video Merger
Merge multiple video clips into a single video while keeping the original quality.
When your recorded AVI or MOV videos fail to play on mobile devices or social platforms, this tool repacks the video stream, converting various container formats into standard MP4 (H.264 encoding). As an ISO-standard multimedia container, MP4 bundles video, audio, and metadata into a single file, ensuring compatibility with 98% of devices.
Q: Why is the converted MP4 larger than the original file?
When the source video uses inefficient encoding, converting it to H.264 may increase the file size, but it ensures smoother playback.
Q: Will the conversion reduce video quality?
No. This tool uses lossless transcoding technology, which only changes the container format without recompressing the video stream.
We recommend a maximum file size of 2GB per conversion. For 4K videos, ensure your device has sufficient memory. Please do not close the browser tab during the conversion process.
For animated videos that need to retain an alpha channel, we recommend exporting them as MOV format before conversion. Typical conversion example: Input a 1080p@30fps AVI file (50MB) → Output an MP4 file with the same parameters (approx. 45MB).
