Lights, camera, comment war
Seedance 2.5
AI video just got scary-good—and the comments are already fighting about ads, spam, and hype
TLDR: Seedance 2.5 is ByteDance’s new AI video maker that can create longer, more polished clips and promises more control for users. The comments were split between people calling it shockingly good for ads and people warning it’s basically a gift to spam, fake content, and closed-off tech hype.
ByteDance is pitching Seedance 2.5 as the next big leap in AI video: longer clips, smoother scene changes, more control, and the ability to juggle piles of reference images, videos, and audio to make something that looks more like a finished mini-movie than a glitchy toy. In plain English: instead of spitting out a few awkward seconds, it can now make up to 30 seconds at once and keep extending from there. That’s the sales pitch, anyway.
But the real show was in the comments, where the crowd instantly split into two camps: "this is amazing" versus "cool, now scammers get better tools." One skeptical commenter basically asked if these models have any real purpose beyond misinformation and spam, which immediately set the mood. Another fired back with a very practical reality check: advertisers are already using AI-made video in major campaigns, so whether people like it or not, the business use case is already here.
Then came the classic open-tech purity test: "No weights, no care." Translation for non-nerds: if the company won’t release the model for others to inspect and use freely, some people refuse to get excited. Still, not everyone was grumpy. One user said the quality looked "extraordinarily good," especially for ad-style content, and another just went full internet caveman with "This looks insane!" So yes: part awe, part dread, part ad-world panic. The machine made a movie, and the comments made a mess.
