Hasta La Motion!

I have a boxing scene in a boxing ring.
One of the boxer is wearing a full chroma key suit and fight is in front of the greenscreen.
For the boxer, only helmet, gloves and shirt will be visible.

I’m gonna shot with Sony EX3…

My test shoot was in 25fps in HD format and there was huge motion blur around the gloves,helmet and shirt.

I’m planning to shoot it in 60fps in SD(720p) format to reduce the motion blur but then it wont be progressive shot and there will be lines because of the interlace.

I’m using video converter to record it directly to Mac in uncompressed format to get a proper color to key.

Is there any solution to fix this problem or another way to shoot it in progressive and HD format :confused::confused::confused:
