00:00 Seance 2.5 is live and everyone's calling it a game-changer, but Seance 2.0 is already the number one AI video model in the world. And right now, [music] you can run it unlimited in 4K. So, the real question is, is 2.5 actually a big upgrade or just a version bump? That's an official [music] Seance 2.5 example. And after going through everything, this is not a small upgrade.

And it's what you can use today. The pre-sale gives you unlimited Seance 2.0 in 4K right now. Seance 2.5 arrives on Higgs Field in 7 days. So, every 2.5 clip you'll see is an official example generation, not something I made myself yet.

01:21 And here's the deal, exactly. Seance 2.5 is live. Get 14 days of unlimited Seance on Higgs Field. 7 days of unlimited Seance 2.0 in 4K. Then switch to Seance 2.5 for the next 7 days. Lock it in once and you ride both models. Now, round one. In 2.0, longer stories means stitching. You generate clips and cut them together and keeping everything consistent across cuts is the hard part.

01:51 Seance 2.5, up to a 30-second continuous generation, one unbroken shot. Character, camera, lighting, scene structure holding from first frame to last. Watch this official example showing on screen. 2.5 and it's not close. 2.0's reference system is already strong. That's how creators keep characters consistent. >> [groaning] [screaming] >> But 2.5 takes it to 50 inputs in a single pass.

02:33 Images, clips, audio, style boards, prompts mapped into the scene and held there. For character-driven stories and brand work, this is the consistency dream. Round two, Cedents 2.0. Here's the pain every AI filmmaker knows. One detail is wrong and in 2.0, your real option is regenerate and pray. Cedents 2.5 brings region level editing.

Audio generated in the same pass, tighter than ever. Dialogue, footsteps, ambiance already sitting in the cut. Listen to this example. >> That sound came with the video. Round four, 2.5. And the quiet one that changes everything, roughly 20% better instruction following with an upgraded encoder holding fine detail.

04:46 Hair, text, small textures across frames. Fewer rerolls, more first-try [music] keepers. Round five, 2.5. That's a [music] clean sweep. So, verdict. This is not a small upgrade.
