Aperture showing videos with odd lines, how to see videos nicely in OSX? I imported my tennis couching videos to Aperture but Aperture shows them with odd lines while QuickTime Player more nicely shows them. Which software should I use for videos because Aperture is clearly not meant for this?

Aperture


  


QuickTime Player


  


P.s. I imported my videos from Sony Nex-3N.
I just went with Final Cut Pro: stored the videos to external HDD and then viewed them there with FCP. Also VLC player as suggested may be an option. Yet FCP is also for editing, VLC for playing. For this purpose just for analysing the shots, FCP and VLC may be a bit off-topic but they can nicely show videos.
