The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Estimated: ByteDance unveiled Seedance 2.5 on 23 June 2026 and promised early July; Atlas Cloud[4] reports a delay to 20 July and a public launch on 31 July via Jimeng and Doubao, a single vendor source.
Opened source supports this specific review extract; publication semantics and any live-benchmark scope are recorded in the research catalog. Does not establish pin event date.[1]
23 June report: 30-second clips with scene changes and no stitching, up to 50 extra inputs, post-hoc editing, and native 4K for Seedance 2.0.[1]
Vendor timeline: delay announced 9 July, reset to 20 July, launch on 31 July; single source.[1]
Says Seedance 2.5 was released in July 2026 with local editing and a beta 3-minute long-video mode.[1]
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
Morphing and decoherence still show up in fast action sequences, even with well-structured prompts, and no amount of upscaling removes it.
Dialogue written in quotes comes back spoken, lip synced, with ambient sound and effects underneath.
On spoken lines the lip sync matches the mouth, so you don't need a separate voiceover or lip-sync tool.
