Action freezes on Nikon d90

[discoman]

I was filming a group of wedding guests dancing at a wedding. I am trying to put all the clips together to make 1 long clip of around 4 minutes, in window movie maker.

However whilst parts of the clip plays ok, there are parts where the clip freezes for a second or two and then carries on as normal, the sound however, stills runs as it should and does not freeze with the clip.

Not sure if I have explained it well but hopefully you will follow what I mean.

What memory cards are you using?

I am using Sandisk 4gb Extreme sd card.

When the image pauses for a while is it still in sync with the sound when it starts up again? if it is then it maybe that your computer is struggling to play the raw video format from your camera. Which is a very common with DSLR footage.

Does the film play ok on your D90? if it does then it points to your computer not being capable of processing the footage fast enough to view in the raw format your camera has produced. I use a Canon 7D for film and my windows based laptop cannot play the straight out of camera footage, it is very very jerky and pauses the image but the sound plays fine, even a high end MAC computer struggles with it, the cure is to convert the raw footage from your camera into a format your computer can cope with. Not sure on what format or size the D90 produces or what format you want the film to end up in, so can't really give you and idea on how best to convert it to editable footage.

hope this helps

Hi Rob,

Thanks for your reply, I think that you have hit the nail on the head, so to speak.

I have just uploaded part of the video to you tube and it plays alright, with no problem at all. Even the transition in the middle of the clip is working fine but before that it was all over the place on my computer.
