ByteDance's video lines. Three generations live in our catalog: v1.5 Pro (cinematic motion), Pro/Lite (cost tiers), and Seedance 2.0 (the new sd-2-* family with native audio sync).

Strengths
  • Tightest scene composition of the major video brands — clean framing, balanced negative space.
  • Cinematic motion: slow camera reveals, parallax, atmospheric drift look natural.
  • Seedance 2.0 (sd-2-*) adds native audio/video sync — voices, footsteps, ambient sound.
  • VIP tier on Seedance 2 unlocks 1080p output and longer durations.
  • Reference-to-video mode (lite-reference-video, sd-2-omni-reference) blends 1–4 reference images cleanly.
Weaknesses
  • Lite tier is noticeably softer than Pro — fine for drafts, not finals.
  • Some sd-2-* variants (Omni Reference No Video) actually output stills, not video — read the model name carefully.
  • Less explosive action than Kling — Seedance leans contemplative.
Best for
  • Atmospheric establishing shots, slow reveals, cinematic landscape
  • Product motion shots — bottles spinning, fabric draping, water pours
  • Story beats that need controlled motion rather than chaos
  • Reference-driven character / location consistency
Avoid for
  • High-energy action — Kling wins there
  • Text-heavy frames
Prompting tips
  • Describe the camera move FIRST, then the subject — Seedance's motion engine leads with composition.
  • Use "slow", "gentle", "glide" verbs for motion — Seedance interprets restraint better than chaos.
  • Mention specific time of day ("dusk", "golden hour", "twilight") — Seedance's lighting engine handles them well.
  • For sd-2 (Seedance 2.0): explicit audio cues in the prompt ("footsteps echo", "distant thunder") engage the audio sync.
Parameter tips
  • camera_fixed: ON for product shots / stable framings. OFF for cinematic motion.
  • generate_audio (sd-2): ON for finals with ambient sound, OFF for drafts to save cost.
  • Resolution: 720p is the practical default; 1080p (VIP) on hero shots only.
