Edit your AI film: rhythm, sound and the first 30 seconds

Assemble your shots, cut for rhythm, add voice, music and effects, and export a video that looks finished on every screen.

Pick your best takes

AI gives you many versions of every shot. Editing starts by choosing: keep the take with the best performance, not the most spectacular one.

• Review all takes of a shot, then keep one and one backup.
• Drop shots with visible glitches in the face or hands.
• Build a rough order first: story before style.
• Aim for a first cut 20% longer than your target, then trim.

Cut for rhythm

AI clips are short, so your editing sets the pace. Most shots work between 2 and 5 seconds.

• Cut on movement: a turn of the head, a step, a door opening.
• Vary the shot size: wide, medium, close-up.
• Use longer shots for emotion and shorter shots for action.
• Hide small glitches at the cut, not in the middle of a shot.

Every generated clip is used whole, 8 to 10 seconds each, one after another.

Only the best 3 seconds of each clip, cut on a movement: Lyra turns her head (cut), the dragon's shadow crosses the ground (cut), close-up on her hand on the bow.

• Picture
• Voice
• Music
• Effects
• Shots of 2 to 5 seconds, the voice on top, the music under everything, effects on the moments that matter.

Watch your cut without sound. If the story is clear, the rhythm is right.

Worked example: a 30-second scene, cut by cut

Here is a short scene from the archer series, as it could look on the timeline. Eleven generated clips became seven shots.

• 0–3 s: wide shot of the burned market at dawn, smoke. Sound: wind, a distant crow.
• 3–5 s: close-up, Lyra opens her eyes. Sound: a single heartbeat.
• 5–9 s: medium shot, she stands up among the ashes. Voice: “Who did this?”
• 9–11 s: insert, a royal arrow stuck in a beam.
• 11–15 s: close-up, her hand pulls out the arrow. The music starts, very low.
• 15–20 s: wide shot from behind, she walks toward the city gates.
• 20–30 s: slow push-in on a soldier watching her from a rooftop. The music rises, then cuts to silence.

Notice the silence at the end: cutting the music on the strongest image often hits harder than a loud effect.

Sound is half the film

A silent clip looks like a demo. With voice, music and small sounds it becomes a scene.

• Voice first: record or generate the dialogue, then cut the picture around it.
• Music second: one theme for the series, lower than the voice.
• Effects third: footsteps, wind, doors, a heartbeat.
• Keep voices clear and music about 15 dB under them; check on headphones and on a phone speaker.

Music at the same level as the dialogue for the whole episode, and no sound effects.

Clear dialogue, music about 15 dB lower that rises only between lines, footsteps and wind under every outdoor shot, and silence just before the reveal.

Win the first 30 seconds

Most viewers decide in the first seconds whether to stay.

• Open on the most intriguing image, not on your logo.
• Show the hero and the problem in the first 30 seconds.
• Put the title card after the hook, not before.
• End the episode on a hook for the next one.

Ten seconds of animated logo, fifteen seconds of landscape with music, then the title.

Close-up of an arrow hitting a door, the hero's face, one line of dialogue that raises a question, and the title at 0:20.

• 0 s · Striking shot
• 10 s · Main character
• 20 s · Title card
• Long credits or logo first
• Most viewers decide in the first 30 seconds.

Export and check

• Export 1080p or 4K, 24 or 30 frames per second, H.264 MP4.
• Watch the whole export on a phone, with sound.
• Add subtitles in your language and in English.
• Declare AI-generated content where the platform asks for it, for example on YouTube.
• Name the file clearly: series, season, episode.

Your first episode in one evening: the editing order

• Import every selected clip and the voice files.
• Lay the voice first and cut the picture to it.
• Trim each shot to its best 2 to 5 seconds.
• Add the music under the whole scene, then the sound effects.
• Color: one look for the whole episode, applied to every shot.
• Titles and subtitles, then export and watch it on your phone.

Save the project as a template: titles, music levels and color look are ready for episode 2.

Final checklist

• The story is clear without sound.
• The sound is clean and balanced.
• The first 30 seconds are strong.
• Subtitles are added and checked.
• Title, description and AI tools are filled in before you submit.

• Cut between 2 and 5 seconds and hide glitches at the cuts.
• Sound makes the scene: voice, music, then effects.
• Hook viewers in the first 30 seconds and at the end.

• CapCut: Quick editing, captions and vertical teasers.
• DaVinci Resolve: Free professional editing and colour.
• ElevenLabs: AI voices and narration.
• Suno: Music and themes for your series.

• Write the story of your AI series, step by step

  From a one-line idea to a season outline: the logline, your hero, the episode map and the cliffhangers that keep viewers watching.

• Keep your characters consistent from shot to shot

  Build a character sheet, lock the look with reference images and check every shot, so your hero is the same person from episode 1 to the finale.
