Jerky video playback on mac pro 2009.

in macOS edited January 2014
Have tried both quicktime and vlc, put video playback seems to be jerky on any panning shots on videos.

Have tried some 1080p trailers from the following link, especially apparent on the new ice age trailer. see page below.

anybody else have this problem? This is on a mac pro 2009.

    The trailers are not posted at your link. That site aggregates trailers from several other sites. The Ice Age trailer is both huge and posted on Of the originating sites represented, is comparatively slow. BTW, do you mean Mac Pro or MacBook Pro?

    I have a 2003 Dual 2.0 GHz PowerMac G5, which is a much older and much less power than your system. The 1080p trailers seemed perfectly OK to me.
