  EX1 blur footage in camera movements

  Posted by David Rogue on November 4, 2015 at 10:14 am

  Hi all,

  I recently started working with two EX1 camcorders. The colors are incredible but I’m having problems in the camera movements. You can download a raw unedited footage in this link:

  As you can see, when the camera is fixed the objects are perfectly focused but when starts moving the focus is lost along the movement until the camera is fixed again. Then, suddenly, focuses again. It happens with any camera movement: pan, on slider, crane, etc. That is only an example.

  As an extra information, slong the movement the peaking is lost and the phenomenon occurs in the two cameras so it is not a problem with one of them.

  I don’t know if it is a problem in my monitoring system, in the camera configuration, the interframe codec compression or any other thing but I can not imagine this good quality cameras can give so noisy footage in the movements.

  Please, check in your monitoring systems if you watch the same thing. Any idea is appreciated.

  Thanks in advance.

  Have you ever made a back focus adjustment?
  please tell us the settings of the shooting.
  MF/AF/FULL MF/ GAIN / SHUTTER SPEED / etc…

  Thanks for the reply. It is not a backfocus problem, the cam focuses correctly along the zoom. I’m carrying out some tests. For the moment, shutter in 1/500 seems to solve most of the problem with slow camera movements. I will post more information when available. I was used to 50p and the 50i of the camera is not so good (a lot of grain) because of that my initial confusion. Now working in 25p.

  Is the steadyshot (image stabilization) on?

  I just looked at your footage. This definitely looks like the steady shot is on and is ‘defeating’ your camera move. Turn it off. Only use the steadyshot when handheld. You should also get Doug Jensen’s PMW-EX1 Field Guide.
