Video playback problem

I have rendered an animation, in a pretty complex scene, with alot of vegetation (alot), cars and people.
so far no problem. the image quality looks great (it was render in medium size and 3 stars quality with 60 frames)
so the deal is that when I play the video, I get this really weird, bad quality huge pixels and the image gets all wrong for a few seconds. I thought maybe there was the video codecs with the windows media player so I gave the animation to a friend and he tested out the video in his macbook pro, to my surprise the video played even worse, getting stock every few seconds!

what could it  be?
any clues?

this is the second time this happens to me and in a different animation and scene

Your PC and mediaplayer apparently can't decode the 60 frames/sec fast enough, so the stuttering and large pixels are decompression artifacts.

The fastest media player is allegedly Media player Classic Home Cinema Edition - try this and let us know if there's less stutter/artifacts:

Remember I said that I had this problem before? well the first time I had the problem the animation was rendered in "Full HD" and with 30 frames. and I had this very same problem.
so I thought if I render only in "HD" and with 60 frames might be better.

I was wrong! :P

I will render this same animation again with 30 frames per second and only in "HD" and I will let you know.

Try Media Player Classic Home Cinema Edition first.

And read this thread if you're still not convinced that it might help ;)

You can also try re-encoding the video with Handbrake:

Yes, any video editor where you can change the bitrate down to <15k and then it will play in most media players and most computers.

It's not the FPS of the video but the bitrate that the media players can't decode and the PC/bus etc can't push through the system fast enough.

The old media player Morten mentions has very low overheads so is able to play things better, but is of course only for Win.
