Put clips together with smooth transitions instead of hard cuts. Add two or more videos, pick a crossfade, fade to black, wipe, slide, zoom or dissolve for every cut, set how long each lasts, preview it, then save one MP4. Clips are processed on your device, never uploaded.

How to use the Video Transition Maker
Add your clips: drop two or more videos on the box. They are joined in the order shown.
Choose a transition and duration, then press Apply to all cuts, or set each cut separately in the list.
Trim and reorder clips with the Start/End fields and the arrow buttons.
Press Play preview or Preview this cut to check the result.
Press Create video with transitions, wait while it renders in real time, then download the MP4.

How the timing works
Each transition overlaps the end of one clip with the start of the next. If the clips last d1, d2, …, dn seconds and the transitions t1, …, tn−1 seconds, then:
Clip k+1 starts at offsetk = d1 + … + dk − (t1 + … + tk), the same value ffmpeg's xfade filter takes as offset.
Total length = Σd − Σt. Three 10-second clips with two 1-second crossfades give a 28-second video.
A transition can use at most 45% of either neighbouring clip, so very short clips get shorter transitions automatically.
Audio uses an equal-power crossfade: the outgoing gain follows cos(πp/2) and the incoming gain sin(πp/2), where p runs from 0 to 1 across the transition. Unlike a straight linear fade, this keeps the loudness steady in the middle of the blend.
Tips
Use one or two transition styles per video. Mixing every effect looks amateur; a consistent crossfade with an occasional fade to black reads as professional.
Trim dead time at the ends of clips first: transitions look best over movement, not over someone reaching for the record button.
Rendering happens in real time, so keep the tab visible. For long projects, copy the ffmpeg command and run it on a computer.
Only need to fade the start or end of a single video? Use Video Fade In and Out. For simple joining without transitions, the Video Merger is quicker.
Frequently asked questions
How do I add transitions between video clips for free?
Add your clips on this page, choose a transition such as Crossfade or Fade to black, set the duration and press Create video with transitions. The clips are combined in your browser and saved as one MP4 or WebM file, with no upload, account or watermark.
Why is my video shorter than the clips added together?
During a transition both clips play at the same time, so each transition overlaps the end of one clip with the start of the next. The final length is the sum of the clip lengths minus the sum of the transition durations. This is how ffmpeg's xfade filter and most editors work.
What is the difference between crossfade and fade to black?
A crossfade (also called a dissolve in editing) blends the outgoing picture directly into the incoming one. Fade to black darkens the first clip completely and then brightens the next one out of black, which feels like a scene change or the passing of time. Fade to white works the same way with white.
How long should a transition be?
Half a second to one second suits most videos. Quick wipes and slides work well at 0.3 to 0.6 seconds, while slow crossfades of 1.5 to 3 seconds suit music videos, travel montages and emotional moments. A transition is automatically shortened if a clip is too short for it.
Does the sound fade too?
Yes, with Crossfade the audio is on, each cut blends the two soundtracks with an equal-power curve so the volume does not dip in the middle. For fade to black or white, the first clip's sound fades out and the next fades in. Turn the option off for a hard audio switch at the midpoint.
Can I use different transitions for each cut?
Yes. Every cut in the clip list has its own transition type and duration. Use Apply to all cuts to reset them all to the type selected at the top.
What is the ffmpeg command for?
It reproduces the same edit with the free desktop program ffmpeg, using its xfade (video) and acrossfade (audio) filters. That is useful for very long or 4K videos, which render faster on a desktop than in real time in a browser.
