官方的亚当项目 https://assetstore.unity.com/packages/templates/film-sample-project-130415

使用了timeline PostProcessingV2 和recorder

https://www.veyvin.com/wp-admin/post-new.https://download.staging-packages.unity.com/com.unity.recorder/-/

可以在运行状态下手动录制，可以在timeline中录制。

亚当项目使用的是在timeline中录制。可以将导出图片，然后在后期软件中制作movie，也可以直接制作mp4 或 webm。运行一遍场景后就导出了影片或图片。

使用ffmpeg 合成影片命令行如下
