Videos & troubleshooting
Will my video keep the original audio, or be silent?
Audio depends on the template and generation mode. Check playback before sharing and clear music rights separately.
Check the selected scene and result
TrendSwap uses curated templates rather than your own reference video. Some workflows render without sound and attach the scene soundtrack before delivery; others retain or generate audio. A silent reference or muted preview does not mean the downloaded video is intended to be silent. The original sample is a reference, not a promise that every output keeps the exact recording or synchronization. Play the completed MP4 with sound enabled before publishing.
If you cannot hear anything
Unmute the player and check device volume, Bluetooth output and whether the browser blocked autoplay with sound. Download the completed MP4 from My videos and play it in another player. If that file is also silent, the issue may be the output rather than your browser. Send support the video reference, template and playback details before paying for another attempt; no audio-repair outcome is guaranteed.
Original sound does not mean licensed music
Payment covers video generation, not music synchronization, master recording or performance rights. A downloadable soundtrack is not permission to use it in ads. Check TikTok or Instagram rules for your account and intended use; an in-app music license may not cover an exported clip or another platform. Replace or license audio separately when needed, using an editor or the destination platform.
