Give a clip a clean start and finish: fade in from black, white or any colour, fade out at the end, and let the sound fade along with the picture. Preview the fades live, then save the video as MP4 or WebM, all in your browser.

How to use the Video Fade In and Out
Choose a video (MP4, WebM or MOV) or press Try a sample clip.
Set the fade in: tick Fade in at the start, drag the duration and pick Black, White or a custom colour.
Set the fade out the same way, and choose a fade curve.
Pick the audio option: Fade with the picture keeps sound and image in step.
Press Create faded video, wait while it renders in real time, then press Download video.
How the fade is calculated
A fade is a colour layer placed over the picture whose opacity changes over time. For a fade in of length d, the layer starts fully opaque and becomes transparent at time d; for a fade out it starts transparent at duration − d and is fully opaque on the last frame. The opacity follows the chosen curve, where x runs from 0 to 1 across the fade:
Curve
Formula
How it looks
Linear
x
Constant change from start to finish
Smooth (ease in-out)
3x² − 2x³
Gentle start and end, quicker in the middle; the most natural
Slow start
x²
The picture stays visible longer, then darkens quickly
Fast start
1 − (1 − x)²
Darkens quickly at first, then settles slowly
When the audio is set to fade with the picture, the volume is multiplied by 1 − opacity on every frame, so sound and picture reach silence and full colour at the same moment.

Tips
Trim the clip first with the Video Trimmer so the fade ends on the frame you want the viewer to remember.
If you are joining several clips, add the fade out to the first and the fade in to the second, then join them with the Video Merger to get a dip-to-black transition.
Fading to white works best on bright footage; on dark night shots a fade to black looks smoother.
Frequently asked questions
How do I add a fade to black at the end of a video?
Choose your video, keep Fade out at the end ticked, select Black and set the duration, for example 2 seconds. Press Create faded video and download the result. The last 2 seconds of the clip gradually darken until the final frame is completely black.
How long should a video fade be?
Fade ins of 0.5 to 1.5 seconds and fade outs of 1.5 to 3 seconds look natural for most clips. Short social videos often use quick fades of about 0.5 seconds, while film-style endings and music videos use slower fades of 3 to 5 seconds.
Does the sound fade too?
Yes, by default. With Audio set to Fade with the picture, the volume follows the same curve as the brightness, so the sound reaches silence at the same moment the picture reaches black or white. You can also keep full volume or remove the sound completely.
What is the difference between fade to black and fade to white?
Fade to black is the classic ending and suggests the end of a scene or the passing of time. Fade to white feels brighter and dreamier and is often used for flashbacks, weddings and memorial videos. You can also pick any colour, for example your brand colour.
Which fade curve should I use?
Smooth (ease in-out) starts and ends gently and looks the most natural, so it is the default. Linear changes brightness at a constant rate. Slow start keeps the picture visible longer before it darkens quickly, and Fast start darkens quickly at first and then gently settles.
Why does creating the video take as long as the video?
The browser plays the video in real time, draws each frame with the fade on a canvas and records the result with the MediaRecorder API. A 1 minute clip takes about 1 minute. Keep the tab open and visible until it finishes.
Is my video uploaded?
No. The video is decoded, faded and encoded in your browser. Nothing is uploaded and no watermark is added.
