Stuttering During Recording and Playback

I took some informal shots of friends at a lawn party and while recording I noticed several sections where there was a lot of stuttering. Playback has the same issue in the same place.

I was recording to Prores 2.5k and writing to a San Disk Extreme II 480GB SSD. Not good!

Is this a common problem?

Any thoughts?

Prorez is not 2.5 k, it is standard high def 1080 x 1920

In the year I have been shooting my BMCC EF, with a recommended card I have not experienced this. On the BMD forum there are recommended card.

I see the Sandisk Extremes on the list, but don't see the Extreme II there.

re: Stuttering During Recording and Playback

Thanks Chris - I erred a bit because I had also tried a few minutes of 2.5k raw. But the issue was in ProRes.

I don't think there is any San Disk Extreme (non II) available any more so (stupidly??) thought Extreme II would be as good if not better.

I've ordered a Kingston card that IS on the list - we'll see if that helps

Frankly I think this whole thing is something of a circus. Camera does make a beautiful video - when it works. Too many lenses don't work with it, too sensitive to the exact SSD in use. By the time I get it all right I'll have spent twice what I paid for the camera if not more.

Jim:

I got lucky and had a card that worked with their HyperDeck that also works with the camera (OCZ 128 GB Vertex 3 (VTX3-25SAT3-128G) ). I bought the 240 Gig version on the list, and both cards have been working over the year.

It is important to note that just because one size card works, another larger gigabyte card may not.

My understanding is the newet cards sometimes claim to be faster, but employ a form of compression that can't be used for video, and because of that, they don't write as fast as claimed.
