Premiere CS4 Choppy video after exporting to H.624 HDTV 23.97

[Lucas 7D]

I tried both HDTV 1080p and 720p and both give me a choppy final video. I had to resort to MPEG-2.

Any advice?

Is this in a Mac environment? If I export any videos in the H.264 MP4 format under Adobe Media Encoder, the videos play fine on a PC, but play choppy on a Mac for some reason.

Are you on win7? MS ships with a poorly optimized decoder and you have to override it to use 3rd party ones

If not, what decoder are you using? for WMP

You can try MPCHC which allows for DXVA acceleration (will make use of your graphics card) if you set it up correctly in the options
