Make a vertical karaoke video for an event in StarSinger

A vertical karaoke video can give an event campaign a shared hook: attendees can watch on a phone, sing along on a display or pass the clip around after the show. The production task is not just to make a song. It is to make a track that names the event clearly, then check that its video and karaoke captions work at the size and pace of the intended screen.

StarSinger’s workflow covers the song and the video. Describe a song in one line and the service says you can hear it sung in about 90 seconds. You can then turn a song into a vertical 9:16 music video with karaoke captions. The full music video uses you in the video from one photo. Here is a practical way to build one for an event campaign without treating the generated result as finished promotional copy.

1. Write a brief that fits the event

Before generating anything, decide what the audience should remember. Keep the brief focused on one event, one audience and one action: the event name, the mood, and a phrase such as the date, venue or ticket reminder. A song packed with every sponsor, schedule item and selling point is harder to follow, especially when played on a phone or across a busy event floor.

Use ordinary language to describe the song. For example: “An upbeat pop song for the Northside Night Market, with a welcoming feel and a chorus about meeting friends under the lights.” Treat that as a direction, not a guarantee that specific words will appear exactly as written. StarSinger’s public description promises a song from a one-line description, but it does not promise exact lyric control.

Keep a second, factual source for details that must be exact. The song can carry the mood; a separate event graphic or announcement can carry the full schedule and ticket terms.

2. Generate and listen before moving to video

Make the song in StarSinger, or choose a song if you already have one available in the service. Listen through the result before committing to a video. Check that the event reference is understandable, the energy fits the occasion and the track does not suggest details that are wrong. A fresh song is available each day at no charge, according to StarSinger’s homepage.

Do not assume that a generated vocal or lyric will be suitable just because the brief was specific. If the song misstates a name or date, avoid using it as the source of truth for that information. For a voice or photo that represents a real person, get their permission before making it part of campaign material.

3. Preview the storyboard before paying

Choose the music-video option for the whole song when the goal is a complete event piece rather than a short teaser. StarSinger lists its full music video at $19.99, paid once, and says it uses one photo to put you in the video. The product page describes the output as vertical 9:16 with karaoke captions. The storyboard preview is free; the listed generation time is about 13 minutes.

Use the storyboard as a checkpoint, not a formality. Look for whether the visual idea feels appropriate for the event, whether the person shown is the right one, and whether the scenes seem consistent with the tone of the song. A previous storyboard review checklist goes deeper on framing, scene changes and continuity. If the planned imagery would confuse attendees or create a brand problem, pause before paying for the render.

4. Review the finished karaoke video on its actual screens

Once the video is ready, watch it from start to finish. Check that the captions follow the vocal, that names and other event-specific words are represented correctly, and that the beginning gives a viewer enough context. Karaoke text is useful only if people can read it. Test the 9:16 video on the actual mobile feed or event display, at a realistic viewing distance and with the sound conditions you expect.

StarSinger describes karaoke captions as part of the video, but its public product details do not specify caption editing controls. If a caption is wrong or hard to read, do not assume it can be corrected inside the service. Keep a fallback ready: use the video only where the issue is not consequential, or choose a different event asset for that placement.

5. Match the clip to the placement

A full-song video suits a display where visitors can stay for the track, or a social post intended to carry the whole campaign song. It may be too long for a quick announcement. For a shorter placement, StarSinger also lists a 20-second clip of the song’s best section for $5.99. That is a different deliverable, not a substitute for checking the full video’s captions and message.

Before publishing, confirm the event details outside the song, secure permissions for any person depicted, and make sure the final video plays correctly on the destination screen. The production sequence is simple: brief the song, listen, preview the storyboard, pay only after review, then test the rendered video in context. That last check is what turns a vertical karaoke video from a generated asset into a usable event promotion.
