为 YouTube 做一支完整长度的 AI 音乐视频

This guide covers the long version made with HeyBop's AI music video generator: planning the arc, holding a character for three minutes, where to spend on quality, what reprises save, captions and export — and one thing to sort out with your distributor before you upload.

Plan an arc that follows the song

A 15-second clip can be one idea. Three minutes can't: one image for a whole song reads as a screensaver. Let the song's structure set the arc:

• Intro: establish the world and the character, with slow moves such as a push in or a tilt.
• Verses: smaller moments and longer shots.
• Choruses: the biggest images and the fastest cutting.
• Bridge: change one thing — the location, the time of day or the palette.
• Final chorus and outro: pay off the opening, or echo its first shot.

HeyBop's AI director plans against the song's sections — choruses get bigger, faster shots, quiet parts get room — and every scene has its own prompt and camera move, so you can steer any part of the arc by rewriting that scene. The prompting guide pairs camera moves with sections.

For a full-length video, take the step-by-step route: the storyboard costs 10 credits, and you can read every scene's prompt and rewrite the ones that don't fit before any clip is generated. A full song takes longer to make than a short, since every scene is generated separately; HeyBop emails you when it's ready.

Keep the same character for three minutes

A 3-minute song cut into 6-second slots has 30 of them, and each shot is generated separately, so drift is the main risk: a face that changes by the second chorus breaks the video. HeyBop handles it in layers. A continuity bible — character, wardrobe, palette, lens, light and world — is written once and applied to every shot. With a character, a character sheet and a still for each scene are painted first, and the clips animate from those stills.

To put a real person, pet or mascot in the video, add a cast: up to three characters, each from up to three photos (a character sheet counts as one). Photos of a person use reference-to-video so the face stays the same. Keep the wardrobe constant unless the song gives a reason to change it, and show the character clearly early on before getting stylised.

For a performance feel, Sing along adds shots in which a character sings the song to camera, lip-synced to the vocals. They sit naturally in the choruses, with the story carried by the verses.

Standard first, Best where viewers look

You never pick a model; you pick a tier. Standard is the default: hero shots — opener, chorus drop, closer, hook — go to the top engine and ordinary shots to a fast engine. Lite puts the fast engine on every shot. Best puts the top engine on every shot at the highest resolution it offers.

For a full-length video, make the whole thing on Standard and watch it through. Then switch to Best only for the handful of shots viewers will remember, such as the opener and the chorus drops, and regenerate just those. Each upgraded shot costs one Best clip — 90 credits for 6 seconds, 150 for 10 — and the rest of the video, the cut and the sync stay as they are.

What a 3-minute video costs

Clips with a person from a photo cost 90 / 150 credits on Lite and Standard and 130 / 220 on Best. The range in the table is reprises: on songs of 75 seconds or more, a repeated chorus can replay the shots made for its first occurrence with a variation — mirrored, a push-in, a slight speed change — for free, typically about 30% fewer generated clips. That's the low end; the high end is every slot a fresh shot.

Every button shows its price before you click, and failed or moderated generations are refunded automatically. Of the plans, Premier ($29.99 a month, 3,000 credits) covers a full music video plus hook cuts, and Studio ($79, 10,000 credits) about five full videos. How credits work has the details.

Captions, export and a vertical cut for Shorts

Lyric captions are optional, timed to the vocals and come in several styles. Export 16:9 at 1920×1080 as an MP4 (H.264). Paid plans export 1080P — Best goes up to 2K on photo shots — without a watermark and with commercial use; the Free plan exports 720P with a small watermark, for personal use.

From the same video, add a 9:16 cut (1080×1920) for Shorts for 10 credits, and take the free 15-second hook teaser, the strongest 15 seconds of the chorus. The guide to TikTok, Reels and Shorts covers what to do with them.

Before you upload: Content ID and your distributor

If your distributor has enrolled the song in YouTube's Content ID, YouTube can match the audio in your own upload and claim it. Content ID lets rights holders block, monetise or track videos that match their reference files (YouTube Help).

The usual fix is to ask your distributor to allowlist (often called whitelisting) your channel before you upload. According to YouTube, allowlisted channels are exempt from future Content ID claims, but claims made before a channel was added aren't released automatically (YouTube Help). How to request it varies by distributor, so check their help pages or ask support. If a claim appears anyway and you hold the rights, you can dispute it in YouTube Studio (YouTube Help).
