Music Video 1.0 turns a song into a finished music video. You upload an MP3 of 10 to 300 seconds plus 1 to 7 style or character reference images, and it produces a video synced to the track, with the output length following the song. It renders at 540P, 720P or 1080P in five aspect ratios (1:1, 16:9, 9:16, 4:3, 3:4). An optional prompt of up to 3,000 characters steers the visuals. The vendor also offers burned-in lyric subtitles, but Jantaris does not expose that option yet.

Best for

  • Full-length music videos for independent artists
  • Vertical 9:16 versions of a song for Reels and TikTok
  • Promo videos for songs made with Mureka V9
  • Quick visual drafts for a label or client pitch

Prompting tips

  • Use references that share one look: the same singer, palette and setting.
  • Fill in title to label the track.
  • Describe the visual arc section by section in the prompt: verse, chorus, bridge.
  • Render at 540P (the default) to check timing, then go to 1080P.
