When using the slowmotion option on the DVX200 the footage gets blurred. I had it set at 25P FHD. Here are two stills images. With and without slowmotion. Have any of you here experienced this?

I don't have this camera so sorry if I'm not much help! What is the "Slow motion option" exactly?

I only ever shoot at a higher frame rate and slow down in post.

Also if you shoot 'slo-mo' at 25fps you're not going to get very good slo mo!

The slowmotion option in DVX200 can be set up to 120 fps in full HD. I have set it to 75fps and by recording in 25p that is 3x slowing down.

The full sensor's pixels are not being read out in 120fps mode. It's doing selective pixel readout with a lower quality debayering algorithm, hence why it's blurrier.

Of the effective pixels used, it only uses a fraction of it, hence why it can scan down the sensor so fast.
