Reducing the frame rate : the smooth video Issue

Question

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?

Answer 1

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.
• Generate animation at 50 FPS and capture it at 25 FPS.
