user11809: This is my smooth video. 
Video details:
Frame rate=60 FPS
Video codec: h264
Not have any audio stream    
I want to convert it to a PAL video, But I can't get smooth video.
How to convert a high frame rate video to PAL format(or reducing the frame rate) Without impact on the smoothness of video?

user1871: In order of preference,

Generate animation at 25 FPS and capture it at 25 FPS.
Generate animation at 50 FPS and capture it at 50 FPS. Then, use FFmpeg to generate a 25 frames & 50 fields per sec stream. Stream should be flagged as interlaced. x264 doesn't do interlaced well, so I suggest video codec ought to be MPEG-2 or DV.
