Q: Final Cut Pro 10.2.1 Automatic Speed doesn't work 60fps to 24fps

Hi,

 

I'm editing a short film with Final Cut Pro 10.2.1 and I wanted to slow down my video from 60 fps to 24fps. When I import it to the timeline and click Automatic Speed it still doesn't use all the frames and it actually uses at 12fps. So now one frame of every 2 frames is frozen. What should I do to get the smooth slow motion?

MacBook Pro with Retina display, Mac OS X (10.7.5)

    Your project should be set to 24fps. Is your clip really 60fps? Is it perhaps interlaced 60i (which would really be 30 frames per second, not 60)?

     

    Please post screenshots showing how your project and your clip appear in the Inspector.

    It looks ok, I don't see why automatic speed would not work. It should retime to about 40%. So if I understand correctly, it appears that you get retiming to about 20% instead. The only obvious workaround that I can see is to set the retime percentage specifically.

    No, I do get it at 40 per cent, but the problem is that it is taking from 24 fps and is not using the extra frames from 60 fps. So the image is not smooth.

    I see. It should just use all the frames, but seems to use half of them and repeat each frame twice...

     

    What do you see in the inspector under "Rate Conform"?

     

    Also, there have been cases of clips being wrongly identified as progressive when they are interlaced.

    Can you open the clip in Quicktime Player and report what it says in the Movie Inspector?
