Hi first time posting. My friends and I are trying to film a movies with sword fights in front of a green screen but I have run into a bit of a snag. My camera at its current settings can't seem to get a clear shot of the sword as it is swung and leaves a semi-transparent blur with the motion of the swords. You can see the green screen behind the blur, which means when i go to chroma key it, the sword will disappear completely. Now I am a bit of a novice when it comes to my camera settings so I tried playing with things like the shutter speed to no avail. This blurring also happens if the subject moves too fast as well. So does anyone have any helpful tips on recording fast moving people and objects? Thanks.
