Vertical Music Videos: Making the 9:16 Cut That Actually Travels
The promo cut is a different edit from the full music video, not a crop. Which section to use, how to compose for a phone, where captions go, and how artists actually use short-form to move streams.
The full music video is the artefact. The vertical cut is what gets it seen.
These are different edits with different jobs, and the most common mistake is treating the second as a cropped version of the first. A 16:9 video squeezed into 9:16 loses two thirds of every frame, usually including the subject, and it opens with an intro that was designed for someone who already chose to watch.
This is about making the vertical cut properly.
The two jobs
The 16:9 version is for YouTube. Someone searched for it or clicked it. They have committed. It can open slowly, run full length, and reward attention.
The 9:16 version is for TikTok, Reels, and Shorts. Nobody chose it. It appeared. It has about a second to justify continuing, it will mostly be watched on mute, and its job is not to be watched to the end — it is to make someone want the song.
Optimising the second for completion rate rather than for curiosity is a category error. A vertical cut that ends with the viewer wanting more has done its job better than one they finished and forgot.
Choosing the section
This is the highest-leverage decision in the whole process, and most people default to the beginning of the track, which is almost always wrong.
Use the strongest fifteen to thirty seconds of the song. Usually the chorus, the drop, or the most distinctive hook. Not the intro — intros are designed to build, and building is exactly what a feed does not permit.
Start on or just before the hit. A short run-up creates anticipation; four bars of ambience loses the viewer before the payoff arrives.
Prefer the part someone would recognise. If the song has a line people would quote, lead with it.
A useful test: if you heard this clip in someone else's video, would you look up the track? If not, pick a different section.
Composing for a phone
Vertical is not a crop, it is a different frame with different rules.
The subject belongs in the middle third. Interface elements cover the top and bottom of the screen — usernames, captions, buttons, progress bars — and they vary by platform. Anything important in those zones will be covered on at least one of them.
Get closer. A wide landscape shot reduced to a vertical strip reads as empty. Vertical rewards close framing: one subject, filling the frame, clearly legible at thumbnail size.
Think in columns, not rows. Compositions that work vertically stack — foreground low, subject centre, sky or space above. Horizontal arrangements of several elements do not survive the crop.
Motion should be vertical or toward camera. Lateral movement leaves the frame almost immediately at this aspect ratio.
The vertical music video generator composes for 9:16 natively, which is the difference between a frame designed for the format and one squeezed into it.
Captions
For vertical, captions are close to mandatory, because most feed viewing is muted.
Show the lyrics of the section you chose. If the hook is a line, that line on screen is what makes someone remember it.
Keep them in the middle band. Same reason as everything else — platform interface covers the edges.
Do not caption the whole song. Dense text across a fast section is unreadable and covers the visuals. Caption the memorable line and let the rest run clean.
Style them consistently across releases. Caption styling becomes part of your visual identity faster than you would expect, and consistency across a catalogue is worth more than any individual choice.
Making several, not one
Because the cost per render is low, the sensible strategy is not one perfect vertical cut but several different ones.
Different sections. The chorus, the bridge, the most unusual moment. Different listeners hook on different parts, and you cannot reliably predict which.
Different visual treatments of the same section. The same twenty seconds with two different palettes will not perform identically.
Different opening frames. The first frame is effectively the thumbnail. It matters more than the rest of the edit combined.
Post them across time rather than at once. A track can support short-form content for weeks, and platforms will show the same song's clips to different people.
Keeping it consistent with the full version
The vertical cut should look like it came from the same project — same palette, same time of day, same visual world. This is what makes the two feel like one release rather than two unrelated uploads, and it is why deciding the visual direction before generating either one matters.
The efficient order is to make the vertical cut first. It is shorter, so iterating on style is cheaper, and settling the look on a twenty-second clip before committing to a four-minute render saves more credits than any other habit. The full-length approach covers the 16:9 side once the look is settled.
What not to do
Do not crop the 16:9 version. It loses the subject and opens wrong.
Do not use the intro. Almost never the strongest part.
Do not put text at the very top or bottom. It will be covered.
Do not use close-ups of faces during vocals. Generated people will not mouth your lyrics correctly, and a mismatched mouth is the fastest way to lose a viewer.
Do not change visual worlds between clips from the same track. It reads as unrelated content rather than a campaign.
The point of the exercise
Short-form is discovery, not consumption. The vertical cut exists to move someone from having never heard the song to having it stuck in their head. Everything about the edit — section choice, framing, captions, first frame — serves that and nothing else.
Judge it on whether people looked the track up, not on whether they watched to the end.
