How do I generate a long video with AI in LeinVideo XXL and what duration is recommended?

LeinVideo XXL lets you set the duration slider from 6 seconds up to 10,800 seconds (180 minutes / 3 hours) in 6-second steps. Because the pipeline is in active beta, it delivers the highest stability and narrative consistency on videos up to 5-10 minutes, while also allowing experimental marathon projects up to 3 hours.

How does the LeinVideo XXL long-video generator differ from ordinary models like Sora or Kling?

Standard diffusion video models generate a single 5-15 second clip. LeinVideo XXL is a complete scenario pipeline: its internal AI Director breaks your prompt down into sequential acts and scenes, assigns your uploaded character and location photos across episodes, and assembles a cohesive multi-minute or multi-hour film.

How does automatic video duration matching from my uploaded audio file work?

When you attach an audio file in Studio (such as a recorded voiceover, lecture, podcast, or music track), the duration slider automatically switches to audio-length mode. LeinVideo XXL measures the exact duration of your audio track and paces the visual scenes to match its content and rhythm.

What is the edit-package (ZIP asset archive) in LeinVideo XXL?

Once generation finishes, your LeinGPT Studio history gives you both the mastered MP4 file and a button to download the source asset bundle (edit-package - leinvidxxl_assets.zip). Inside the archive are all individual generated scenes and project materials so you can open them in Premiere Pro, DaVinci Resolve, or CapCut and fine-tune any segment.

How much does long video generation cost in LeinVideo XXL and are there free minutes?

LeinVideo XXL pricing is transparent and per-second: on the base plan, each second of finished video costs 2.0 ₽ (1 minute = 120 ₽, 5 minutes = 600 ₽). With LeinPremium you get 50% off at 1.0 ₽/sec (1 minute = 60 ₽, 5 minutes = 300 ₽). And LeinElite includes 600 seconds (10 full minutes) of LeinVideo XXL generation completely free (0 ₽)!

Do I need to keep my browser tab open while a long video renders, and what happens if a job fails?

No, you do not need to keep the tab open. LeinVideo XXL jobs run asynchronously on our dedicated cluster (the background poller tracks act-by-act progress and saves the finished video to your history and chat). If a technical error or timeout occurs, LeinGPT billing automatically refunds 100% of the charged balance.

LEINVIDEO XXL - WE BUILT AN AI GENERATOR FOR LONG VIDEOS UP TO 3 HOURS

While ordinary video AI models are limited to 5-10 second snippets, we launched our proprietary scenario pipeline LeinVideo XXL to generate continuous long-form videos from 6 seconds up to 3 hours (180 minutes / 10,800 seconds) without VPN. Its built-in AI Director structures your story into sequential acts and scenes, preserves up to 10 reference photos, automatically matches video length to your uploaded voiceover or music, and delivers both the final MP4 and a full ZIP archive of every scene (edit-package).

How to generate a long video with AI: the AI Director breaks your script into acts and scenes, syncs visuals to your audio, and outputs both the finished MP4 and a ZIP package of all source scenes.
