Dropped Frames ?
When the 700 switches from the "A" slot to the "B"" slot during recording, it drops between 3 and 6 frames during the transistion ? ? ?
I am not sure if it is at the end of "A" card or the beginning of "B" card? Not good. Any ideas? Ron |

I've gone through the A to B a few times and never had a dropped frame. What cards are you using?

Perhaps it is dependent on recording mode?
I shot some footage over the weekend that crossed from Card A to Card B and I'll check later today if there are any dropped frames. I was shooting in 1920x1080 24P. Also check your firmware version... do you have the firmware that allows for Class 10 cards? |

OK, I've checked my recent footage and I've prepared a short example on Vimeo:
I didn't see the dropped frames effect, so there is hope! It may just be some combination of card, frame rate, record mode, firmware, etc. Can you put together a similar example which shows the problem you're experiencing? |

The problem is the use oft Transcend-SDHC-cards higher then 8 GB, JVC-technicians from the headquarter said to me, that they don't use Transcend-SDHC-cards anymore, because to many problems.
I lost a lot of my SDHC-cards from Transcend. |

Interesting Eric.
A couple of observations from my footage. a.) No matter how hard or times I try, there is still one frame missing during the switch from Card A to Card B while recording. You can see it and hear it, if your looking for it...fast but it's there. b.) I am using the Transcend 16 GB class 10 cards and in the past I was using the class 6 cards (before the upgrade) c.) I don't ever remember the same problem with Class 6 cards in the past Hmmm.... you might be onto something here Eric (see previous post) Has anyone else had problems with the Class 10 Transcend Cards, especially with a missing frame during the switch from Card A to Card B?

I haven't had any issues with dropped frames using Adata 32GB class 6 and 10. I did have one fluke ( posted a little earlier on this board) and have not had a recurrence using the same card
I think others (including one of the sponsors/dealers) have had issues with the transcend cards
