It could be that the source of the music you used had a limited duration available. Or, it might be that the software or platform you're using has some default settings that capped the music length at 5 seconds.
There could be a few reasons. It might be a technical issue with the encoding or compression of the music file. Or, perhaps the license for the music only allows for a 5-second snippet. Another possibility is that you didn't select the full track properly when adding it to your story.
Perhaps you didn't give enough background or context. A story needs a solid foundation to expand. Maybe you also didn't explore the emotions and motivations of the characters thoroughly, making it seem too brief.
The limitation on your story music might be because of legal requirements or technical limitations of the software or service you're relying on. Maybe you need to upgrade or obtain additional permissions to access a wider range of music.
Maybe there's a technical glitch. Check if your device's audio settings are correct or if the music file is corrupted.
Maybe there's a glitch in the app or a compatibility issue with your device. Try restarting both and see if that helps.
To make story music longer than 15 seconds, you could consider adding a bridge or an interlude. Experiment with different chord progressions and melodies within the piece. And don't forget to build up and release tension throughout to keep the listener engaged.
The shortness might be due to not spending enough time on descriptions, dialogues, or developing the conflict. You could also look at the pacing and see if it's moving too quickly.
Maybe there's a limit set by the IG platform. Sometimes they have specific rules for the duration of stories.
Perhaps it's a story that focuses on one simple action or emotion that can be expressed in just 3 seconds, like a sudden surprise or a brief moment of joy.
You might try looking for longer versions of the songs you want to use. Sometimes, artists release extended or full-length versions of their tracks that you could use instead of the shorter ones. Also, some music libraries specifically for social media offer longer clips for Insta stories.
You can try adding more musical elements like additional instruments or harmonies to extend the duration naturally.
