Hello,
I have used Spine to render short clips and it's reasonably fast. If you keep the video to standard sizes, it doesn't take longer than rendering with other programs such as After Effects.
Note that changing settings such as the compression rate may change the rendering speed.
你好，
我使用 Spine 来渲染短片，而且速度相当快。 如果您将视频保持为标准尺寸，则不会比使用 After Effects 等其他程序进行渲染花费的时间更长。
请注意，更改压缩率等设置可能会改变渲染速度。
