Memory card question
 

I have two Lexar Professional 16gb UDMA cards, 300x & 600x speed.

When I shoot on the 300x card for a continuous sequence (stage play or wedding etc.) I get a MXF movie file made up with several clips, which should form a continuous movie.

Each clip is roughly 1.90gb. I use the Canon Utility to transfer all the files to a hard drive. Now when I bring these onto the timeline (Premiere) the sequence joins are not smooth, I get about 10 seconds of dropped frames and the audio track jumps from being two audio channels to one stereo channel. I have attached an image to show the problem, notice the dropped frame at the start of the next clip.

The problem doesn't seem to occur with the 600x card

Does anyone else use the Lexar 300x cards and do you have the same problem?

I guess if you are shooting lots of small clips then this problem will not show itself.

No answers?

Perhaps you could let us know which make and speed cards you are using and if you can spare the time, put your camera on a tripod and let it run for 20 minutes or longer and see if the clip can be added to a timeline without breaks at the 1.9gb point (8.5 minutes approx)
