    If you are using the original meizu converter, you will get choppy playback for 2 reasons :
    - it only uses 18 fps instead of the supported 20
    - it downscales the fps by dropping frames instead of calculating intermediate frames (framerate conversion)

    Simple solution ? Try BatMan. It offers 20fps and proper framerate conversion at a snap of your fingers. If you like to go the hard way, use VirtualDub.
    BatMan, the free video converter for Meizu players. Problems ? English First Aid here. Deutsche Erste Hilfe hier.

    >the video gets frosen sometimes.

    too high (peak) bit rate ; the M6 has limited cpu power ; you should keep somewhere to 300kbits , possibly even.. lower as for the average target bit rate ( not much to loose ; imho)

    >it laggs..

    audio is out of sync ? this can be fixed ; but...

    it looks like you should , effectively , give a try at Batman that is definitely a solid no brainer solution , if you don't want or know how to set things "manually" using VDub + XviD for instance

    given there is also rather little to gain , going "the hard way"


    --------

    now I disagree with this

    >it downscales the fps by dropping frames instead of calculating intermediate frames (framerate conversion)


    a frame rate conversion remains some mixed combination of : drop frames , or drop and duplicate frames, or duplicate frames ; with a calculation mode that does not take in account the ' visual importance' of frames ; in the first place simply for the ...smoother possible new rate

    so there is no 'calculation' ( ie no 'interpolation' ; which is what could come to mind ) of "intermediate frames" (no 'new' frames !? ) when doing a frame rate conversion ...
