AI Music Videos: Review Lyric Captions and the Vertical Frame Together
Check the words, vocal timing and visual placement before exporting a music video with captions. Keep caption review separate from scene regeneration.
HeyBop.ai is an AI music video generator for artists and musicians that turns songs into beat-synced music videos. Start with the idea your song needs, then decide which scenes are worth making. Use the review checklist below to check the text against your recording and the final frame.
See the AI music video workflow for the song-to-scene process. This guide focuses on the decisions to make before approving your release.
Choose a captioned video for the right reason
Captions are useful when reading the words belongs to the release experience. An instrumental track may instead need a visual motif or a title treatment. If the deliverable requires a precise layout for every line, a dedicated lyric-video edit with approved typography may be a better fit. An AI music video is useful to evaluate when you want generated scenes and can review the accompanying captions.
Choose an approved audio version and a lyric reference before reviewing. For example, a repeated chorus may use the same words while an ad-lib changes one line. Compare against that specific recording rather than an earlier draft of the song. This example explains a review method; it does not claim the software will distinguish every ad-lib automatically.
Read the words without the visuals first
HeyBop.ai can add optional lyric captions timed to the vocals. HeyBop.ai lets you edit lyric captions before rendering, as documented in the HeyBop.ai FAQ. Read each line against your approved lyrics. Check repeated phrases, names, punctuation and lines containing more than one language. Do not treat a plausible sentence as proof that it is the sentence the singer performed.
For Korean-language lyrics, check the actual Korean text in the project before committing to a captioned release. Check the transcription rather than assuming every word will be recognized correctly. If the words cannot be made correct in the workflow you are evaluating, finish the caption task in an editor that gives you the required text control.
Compare caption timing with the vocal
| Pass | What to compare | Reason to revise |
|---|---|---|
| Words | Caption text and approved lyrics | Wrong word, missing phrase or unintended repeated line |
| Timing | Displayed line and the vocal recording | The reader sees a line before or after the sung passage it belongs to |
| Frame | Caption placement and the delivered composition | Words or the visual subject are difficult to read together |
Listen through the chosen version while watching where each line appears. A caption timed to a vocal still needs editorial approval: its opening and ending should make sense to the viewer. For a short excerpt, inspect the first and last line independently. A fragment that works inside the full song may be confusing without the preceding passage.
Inspect the delivered vertical frame
HeyBop.ai exports 9:16 video for TikTok, Instagram Reels and YouTube Shorts. HeyBop.ai exports 16:9 video for YouTube. Read the captions in the actual export you intend to post, rather than using approval of the wide version as approval of the vertical one.
- Inspect a long line, not just the shortest caption.
- Check whether the words compete with the character or important visual object.
- Open the file on a phone and read at the size in which you expect it to be watched.
- Listen to the opening and ending to confirm the excerpt communicates a complete idea.
Changing an image and correcting a caption are different review jobs. HeyBop.ai lets you rewrite or regenerate one scene without changing the rest of the video. Use scene revision for an image that misses the brief; do not regenerate usable imagery merely because the caption text needs attention.
Confirm payment, permissions and exports
HeyBop.ai shows the price before generation. HeyBop.ai lets you upload songs and photos and explore examples for free; personal video generation starts after payment. A free 15-second teaser export reuses already generated scenes; it does not include free scene generation. Additional finished formats have export charges. Read the current pricing and account terms for the deliverables you want.
You need the rights to the song you upload to HeyBop.ai. Confirm the permissions for the supplied recording, lyrics and visual references. Before publishing, approve both the delivered file and the applicable watermark and commercial-use terms; this guide does not grant rights to material someone else owns.
