    Flash Video slow on Mac, normal on Windows

    Is there a reason why my Flash Video(.swf) is slow on Mac and normal speed on Windows?
    It's output is 30fps, but looks sloooooow as on Mac.

    What resolution is the video, what framerate, what spec is the mac, what codec is the video encoded in?

    Thanks for the reply.

    Video res: 998 * 500
    Framerate: 30fps, but my home pc and macs at work show it at about 12fps
    Mac is a G4 and seems pretty good, what more do you need to know for spec, video card type?
    Codec: VP6 Codec, I believe.


    Thanks for any advice, very much appreciated.

    have a look at this pdf

    There's some info in there regards what to expect with flash video /cpu /resolutions.

    A G4 is too low spec to really play that resolution of video using flash. Bearing in mind G4's are way before mac's started using intel processors, and that flash always ran a lot slower on macs in those days. You could improve matters possibly by using a swf playing a lower resolution but with a fullscreen view mode to zoom (this uses hardware acceleration if the browser has a recent version of flash player installed).

    Hi,

    I'm also in Scotland West-coast though.

    We've even tested it on G5s.

    Main problem is it plays very slow, seems the frame rate is much slower than on my PC.

    We tried running the original .mov file and it runs at normal speed on all computers, so it must be the way we're creating/embedding the .flv file, then exporting the swf?

    Could I perhaps show you the swf file so you can see for yourself?

    Sure, send through the info.
    When you play the original quicktime .mov and it plays back in quicktime it's being hardware accelerated by directx on windows (dunno about mac but would presume the same). A G5 is still not very good at playing back cpu intensive swf's as it's pre-intel.

    Hi EastCoast,

    Did you get the PM I sent over last night?

    Is it suitable if I call you?
