Face Swap Video Tutorial: From Clip to Finished Video

What you need before starting

This face swap video tutorial assumes nothing. You do not need editing software or experience. You need an iPhone on iOS 17 or later or an Android phone, the ActLike AI app, and two things to feed it.

• A clip of one person, up to 20 seconds long. Their movement and expressions are what your character will follow.
• A character: either a photo you own or have permission to use, or a short written description of an original character.

Choosing a clip that works

Every face swap video tutorial should start here, because the clip decides how the head moves, how the light falls and how many credits the video costs.

One person, clearly framed

ActLike AI is designed for clips of a single person. A subject filling roughly a third of the frame gives the model the clearest signal to follow.

Nothing crossing the face

Hands, microphones and hair blowing across the mouth all interrupt tracking. Choose a take where the face stays visible throughout.

Steady beats shaky

Gentle camera movement looks natural. Heavy handheld shake, however, blurs individual frames, and blurred frames soften the result.

Shorter is cheaper

Credits are charged per second, so a 6-second clip costs half as much as a 12-second one. Five to ten seconds is the practical sweet spot.

Preparing the photo

If you use a photo, it carries the identity, so its quality sets the ceiling for the whole video. Four things matter, and none needs a better camera.

1. 1Light the face evenlyFace a window in daylight. Even light shows every feature; a hard side shadow hides half of them.
2. 2Look at the cameraA front-facing photo adapts to more head positions than a three-quarter profile.
3. 3Keep a neutral expressionA neutral face adapts to whatever the person in the clip is doing. A wide grin fights it.
4. 4Remove obstructionsSunglasses, hats and hair across the eyes all reduce accuracy.

The app runs a photo check before generating, and warns you if a photo is too dark, blurry or turned away, so a weak photo never costs you credits.

The face swap video tutorial in three steps

1. 1Add your clipChoose the video of one person from your library. It can be up to 20 seconds long.
2. 2Add your characterAdd a photo, or describe a character in words, for example "a weathered sea captain with a grey beard". Describing an original character avoids any question of whose face it is.
3. 3Pick a quality and tap GenerateCredit Saver 480p for ideas, Best Quality 720p HD for the final cut. Turn on Scene Match for anything you will share. The video is ready in minutes.

What each setting costs

A 10-second video therefore costs 10 credits at 480p, 11 with Scene Match, 20 at 720p, or 21 at 720p with Scene Match. Full pack prices are on the pricing page.

Fixing the common problems

The result looks soft

The photo is usually too dark or too small. Retake it facing a window in daylight.

The character slips during movement

The clip probably has motion blur or something crossing the face. Choose a steadier, unobstructed take.

The lighting looks wrong

Scene Match was probably off. Turn it on and generate again; it costs one credit.

A video failed

The app returns the credits automatically, so trying again with a different clip costs nothing extra.

Saving and sharing

Every video stays in your History in the app. Save it to Photos or share it straight to other apps; the file works everywhere, including TikTok and other short-form platforms.

Before you post, check two things: that you have permission for any real face you used, and whether the platform offers an AI label. The acceptable use policy sets out the rules.
