About the Video Merger
Clips multiply: the intro on the phone, the demo from the camera, the ending recorded twice. This merger turns the pile into one video with the unglamorous work done right: mismatched sizes normalized without stretching, frame rates steadied, audio resampled to a common standard, then a clean join in exactly your order.
Everything happens on FFmpeg inside your browser, so event footage and client material are not uploaded to be stitched. The output is a single standard MP4 that plays anywhere, ready to compress or trim further with the neighbouring tools here.
Keep the list honest and the merger rewards you: same story, one file, no editor suite required.
Video Merger FAQs
Yes, that is exactly what this merger is built for. Every clip is normalized to a common frame: scaled to fit, padded where needed, set to a steady 30 frames per second, and its audio resampled to match, before the clips are concatenated. A vertical phone clip and a landscape camera clip can join into one video; the vertical one is pillarboxed rather than stretched, because distorted people are a worse outcome than black bars.
