Default video playback too slow in pt 11

imported a H.264 video into my pt 11 session. Made sure the settings timecode and frame rate matched in the session settings. The sound plays fine but the video is playing slow and jittery. This is the first time this has ever happened. I score films all the time. Not sure why. Please advise!
my specs:
Zbook G2
Intel processor core i7 vPro
Windows 7
ProTools 11.3.1
Scarlett Focusrite
+ Saving to External Harddrive

-psychedelic-punk by night.

h264 is no good for PT , specially with extreme compression ,
but simply playback should work...
try to export the video to ProRes Proxy Codec

( you can use for this mpeg-streamclip (freeware))
and try again...
for editing and recording is h264 a pita because PT jumps always
to keyframes while scrolling .

but since simple playback should work , its worth to look at
the graphics-card/driver..

system specs?

As you are on PC with Windows, I would suggest you use Streamclip or Handbrake and convert the files to DNxHD36, a format, like ProRes, that PT is very happy with.

Have you manually set PT's frame rate to match the video?

Open the video in QuickTime and export as 720.... smaller file and plays perfectly.
