04 — Verdict

Seedream 5.5 strengths and trade-offs

Strengths

  • Strong multi-turn stability: unedited regions stay consistent across dozens of serial edits
  • Native RGBA transparency handles tricky edges like feathers, fur, and brush calligraphy in one pass
  • Much cleaner dense small-font text and more natural, de-glossed photographic skin than 5.0 Pro
  • Supports 1K–4K output, 9 aspect ratios up to 21:9, and multi-reference editing on ImgToVid

Trade-offs

  • Complex refractive transparency—clear glass, water bubbles, acrylic—can still keep a faint grey fill
  • Fine anatomy (thumb length, leg-to-skirt transitions) and tiny props like thin wire-frame glasses can occasionally warp
  • Works best when you change one element per turn with an explicit “keep everything else unchanged” instruction

06 — How it works

How to generate and edit with Seedream 5.5

  1. Step 1

    Describe the scene or one clear edit

    For new images, name the subject, lighting, and whether you want a transparent background. For edits, say “only change X to Y and keep everything else unchanged.”

  2. Step 2

    Upload references when identity matters

    Attach your source photo or reference images to lock character identity, product shape, or typography layout.

  3. Step 3

    Set ratio and resolution in Create

    Pick aspect ratio (1:1, 9:16, 16:9, 21:9, and more) and resolution, then generate in the ImgToVid Create workspace.

08 — FAQ

Seedream 5.5 FAQ

What is new in ByteDance Seedream 5.5?

Seedream 5.5 focuses on three upgrades over 5.0: more stable multi-round editing, native RGBA transparent backgrounds, and cleaner small text with more natural skin and materials.

How do I get the best multi-round edits?

Change one detail per turn with phrasing like “Only change the jacket to brown leather; keep the face, lighting, and background completely unchanged.” Put on-image text in quotation marks to keep signs and badges sharp.

What works best with transparent backgrounds?

Stickers, character cutouts, hair and feathers, logos, and calligraphy usually come out with clean alpha edges. Complex refractive objects like clear glass cups or water bubbles may still show a slight grey tint.

Which resolutions and aspect ratios does ImgToVid support?

You can generate across common ratios including 1:1, 9:16, 16:9, and 21:9, with resolutions from 1K and 2K up to 3K and 4K, plus multi-reference inputs.

Can I use the images commercially?

Commercial use depends on your ImgToVid plan—check Pricing and our Terms before publishing. Make sure your prompts and uploads do not infringe on anyone else’s rights.
