Show HN: I benchmarked Seedance 2.5's 30s one-take video against 3 models

A Hacker News user benchmarked ByteDance's Seedance 2.5 video generation model against three unnamed baseline models, finding that Seedance 2.5 produces superior texture detail, continuity, and editing control for single-take videos up to 30 seconds. The benchmark highlights Seedance 2.5's ability to maintain visual coherence across longer sequences and support multimodal references, with output options at 480P, 720P, and 1080P via VideoAll.ai.

Normal Video Model Baseline A standard AI video baseline for the same old-book store scene. Create cinematic AI videos up to 30 seconds with precise editing, multimodal references and production-ready texture control. Seedance 2.5 turns text, images, video and audio references into cinematic video with longer continuity, flexible direction and targeted editing. It is built for creators who want a final-quality result without rebuilding every shot from scratch. The same old-book store scene reveals the difference between a baseline generation and Seedance 2.5 texture directions. Clean wood, paper and fabric detail with reduced grain and warm window light. Natural wood grain, paper fibers, sweater yarn and documentary-like detail. Stable 35 mm grain, floating dust and high-contrast retro cinematic color. Build coherent scenes without stitching short clips together. Continue a story up to three minutes while keeping visual continuity. Use image, video and audio references to guide style, characters and world. Change a specific element without recreating the entire video. Choose 480P, 720P or 1080P for the balance of detail and credits you need. Hold appearance, costume and props together across longer takes. Produce finer texture and more lifelike human movement. Direct pans, tracking shots, zooms and framing with a prompt. Seedance 2.5 supports 4 to 30 seconds in a single generation. You can extend a sequence through multiple rounds for longer storytelling. VideoAll.ai currently supports 480P, 720P and 1080P output for Seedance 2.5. Seedance 2.5 adds longer single-pass clips, richer reference control, precise editing and stronger texture and continuity controls. Choose Seedance 2.5 in Text to Video, Image to Video or Video to Video, add a prompt or references, choose your settings, then generate.
