Prism 实验版experimental build
在 FreeVideo 里本地运行腾讯开源的 Prism：从一张首帧生成 1280 × 720、8.5 秒、带人声音效的视频，与 MiniMax H3 并存。Run Tencent's open Prism locally in FreeVideo: a first frame becomes a 1280 × 720, 8.5-second video with speech and sound, next to MiniMax H3.
必读须知：Prism 目前为尝鲜测试版。现在支持的加速版本在速度和质量上可能不如生态成熟的 MiniMax H3，仅供尝鲜测试。推荐使用 MiniMax H3。
Read first: Prism is an early-access preview for trying out. Its current accelerated version may be slower and lower in quality than MiniMax H3, whose ecosystem is mature. We recommend MiniMax H3.
安装前请看Before you install
- 配置：NVIDIA RTX 30 系及更新、显存 12 GB 起（8–10 GB 显卡暂不支持）；内存建议 32 GB（最少 20 GB）；Prism 需约 100 GB 可用磁盘，建议 NVMe 固态硬盘。
- 已装 FreeVideo：测试版会原地升级现有安装。在「安装」→「模型」中保持 MiniMax H3 勾选，再勾选 Prism；下载 Prism 期间 MiniMax H3 暂时不可用，下载中断请重新点「安装」。
- 生成较慢：RTX 4070 上轻量档一条约 28 分钟，其他档位更久；生成期间请保持电脑不休眠。
- 更新：测试版会自动更新到新的测试版。如果你在 10 月 7 日 10 点（北京时间）之前下载过测试版，请重新下载一次，并不要接受升级到正式版 v0.3.1 的提示（正式版不含 Prism）。
- 浏览器提示“不常下载”：选择「保留」；Windows 提示“已保护你的电脑”：点「更多信息」→「仍要运行」。
- Linux：
git clone -b prism-beta https://github.com/FlashML-org/FreeVideo.git，然后./setup.sh --video-models h3,prism。
- Hardware: NVIDIA RTX 30 series or newer with 12 GB of VRAM or more (8–10 GB cards are not supported yet); 32 GB of RAM recommended (20 GB minimum); about 100 GB of free disk for Prism, preferably an NVMe SSD.
- Already using FreeVideo: the test build upgrades your installation in place. Under Installation → Models, keep MiniMax H3 checked and add Prism. MiniMax H3 is unavailable while Prism downloads; if the download stops, click Install again.
- Generation is slow: Light takes about 28 minutes on an RTX 4070, the other levels longer. Keep the PC awake while it runs.
- Updates: the test build updates itself to newer test builds. If you downloaded a test build before 02:00 UTC on October 7, download it again and don't accept the update to v0.3.1 (the regular release has no Prism).
- “Not commonly downloaded” in the browser: choose Keep. “Windows protected your PC”: More info → Run anyway.
- Linux:
git clone -b prism-beta https://github.com/FlashML-org/FreeVideo.git, then./setup.sh --video-models h3,prism.
