I've searched a few forums but can't find any threads on the 5D mark II HD movie issue. I bought the cam and was excited about the feature of recording full HD movie as Canon claimed. Test shot a few HD movie clips with a genuine 16GB Sandisk Extreme III CF card. No problem with recording. But when playback, the movies always seem to be jumpy, like it's only 15 frames per second, especially when you pan or tilt. I tried both Quicktime and Canon's Zoom EX. Zoom EX plays a bit smoother than Quicktime, definitely doesn’t look like 24 – 30 frames per second. Anyone else has the same experience? Is there something I am not doing right or it’s just the way the video is?
On a different note: I noticed is the Mark II tends to over expose by at least half a stop than my old 5D.
