UPDATE:
I use a transcend 32 gb Class 10 card.
I got 1920x640 for 185 frames, 1280x640 @ 375 frames and those imported without a problem. Videos play fine and the 1280x640 looks pretty good scaled up to 1920x1080.
I do have problems with other resolutions.
When I shoot at Resolution : 1734 x 726 I can get 173 frames. The problem comes after converting to the DNG using the osx version of RAW2DNG. I can't import them in any of my Camera Raw programs (After Effects, Lightroom, Bridge) they all say "the file format module could not parse the file. (45 :: 35)"
Do I need to use the most updated version of raw2dng? I have an older version of it from a few weeks ago.
