Fast workflow
Designed to reduce friction with direct upload, quick processing, and one-click export.
Open Video Merge, add your file, then choose the target output and run conversion.
This tool is optimized for video processing and works best with mp4, avi, mov, mkv, webm as inputs.
When processing completes, download the result in mp4, webm, avi and verify quality before sharing.
Video Merge is a privacy-first utility for fast video processing. It helps you move from mp4, avi, mov, mkv, webm to mp4, webm, avi with consistent output quality.
Designed to reduce friction with direct upload, quick processing, and one-click export.
Files are handled in an isolated processing flow with minimal retention and clear user controls.
Outputs are tuned for real use cases across mp4, webm, avi.
A predictable sequence keeps conversion stable across devices and file sizes.
Video Merge accepts mp4, avi, mov, mkv, webm and exports mp4, webm, avi.
The pipeline is designed for privacy-first processing with clear user control over inputs and outputs.
Use high-quality source files, choose the closest matching target format, and avoid repeated reconversion cycles.
Video Merge follows a deterministic conversion flow so results are repeatable and easier to troubleshoot when a file behaves unexpectedly.
Combine multiple video clips into a single continuous video.
All video files are uploaded to ConvertCraft VPS servers and merged in an isolated FFmpeg pipeline. Source files and the merged output are permanently deleted from the server immediately after processing — no intermediate files or cached copies are retained.
Concatenates multiple video clips into a single continuous file using one of two strategies. When all inputs share the same codec, resolution, and frame rate, the concat demuxer performs stream-copy concatenation — -c copy — which is instantaneous and lossless. For mixed-format inputs, the concat filter within filter_complex re-encodes all video and audio streams to a unified output using the selected codec and resolution settings.
Ideal for joining clips from a split recording session, assembling highlights from multiple source videos, combining separately filmed segments into a single montage, or stitching together chapters that were exported as individual files. Also useful for reassembling a video that was split for file-size limits or multi-part uploads.
