    I always convert footage from the Canon 5D to ProRes 4444 (or some other intermediate codec) before use in editing applications or AE, as I find the native files somewhat unreliable to work with.


    Also make sure AE is not inappropriately assuming your footage is interlaced by checking the Interpret Footage dialog for each footage file.

    there is only 1 thing i know, if i put hd 720p 60 fps the video will be very smooth but the 60 fps doesnt have full hd and if i put full hd 1080p 24/25 fps the actions inside my video will be unsmooth!!!


    is it because of my camera settings or what ? because some people said This is default video quality of 5D mark III (unsmooth)  and I have to fix it in editing applications.


    You can't have it both ways with that camera.  If you want smooth motion, shoot 720p60.  If you want full hd -- but I don't know why that would be very important -- shoot 1080p 24.


    Which do you want smooth motion or a bigger image?  Pick one.

    Again I say, "Pick one".

    The lower the frame rate the higher the likelihood that you will have juddering motion in panning shots or with objects moving through the shot. Any cinematographer worth his wages will know all about critical panning speeds. The strobbing effect can be so bad that it renders a shot un-watchable even when you are using a $500,000 Imax camera and 70mm film. It's just physics and a little thing that makes our eyes and brain work together called retinal retention.


    If you always want smooth action, shoot at a high frame rate. 25 is slightly better than 24, 29.97 is a lot better than 24 and a lot easier to shoot. 60 is even better. 120 is smooth as butter but you get a different look to the motion for each frame because the higher the frame rate the lower the motion blur.


    If you have judder in the shot and the timing is not critical you can eliminate or remove the juddering by speeding up or slowing down the shot. This will foul up audio sync but it will make the shot usable.
