Side by Side Video
100% private — runs on your device, never uploaded. Works offline once loaded.
Two clips playing at once is how a comparison actually reads: before and after, two takes of the same lift, a reaction beside the thing being reacted to, a tutorial next to the screen it describes. Side by side suits portrait clips, stacked suits landscape ones, and each video is letterboxed into its half rather than stretched, so nothing is distorted however different the two sources are. Choose which soundtrack to keep — or mix both — and the result ends when the shorter clip does. If you want them one after another instead, switch to Join videos on this page.
Matching two clips that do not match
Two videos almost never share a resolution, an aspect ratio or a frame rate, and forcing them into one frame is where side-by-side tools usually go wrong — one clip ends up stretched, or the join stutters. Each clip here is scaled to fit its half of the canvas and padded with black, so shapes are preserved however different the sources are, and both are set to the same frame rate before they are joined.
Choose the layout to match the clips: two portrait phone videos belong side by side, two landscape clips belong one above the other. Putting two landscape clips side by side leaves each of them tiny between wide black bars.
Sound, and length
Two soundtracks at once is rarely what you want. For a reaction or a commentary, keep one and leave the other out; mixing both works only when one of them is quiet. The result ends when the shorter clip does, which is almost always right for a comparison — trim the longer clip first if you need to choose which part of it appears.
Frequently asked questions
Can I put three or more videos together?
Not in one pass. Combine two, then use the result as the source and add the third — the studio lets you chain it. For anything more elaborate, the timeline editor handles multiple layers.
How do I sync the two clips?
Both start at zero here. If one needs to start later, trim its beginning first so the two line up before combining.
