  1. Hi guys. Post done and controlled test's carried out. The Conclusion: The Gimbal After centring the gimbal this time we believed the precision adjust bolts were not tight enough to hold the calibration the last time we used the blue whale. (the manual mentions not to over tighten them, but i think we were a bit to generous and left them too loose) If the problem develops again we will most likely have Tiffen look at the gimbal, but so far so good. Off to a different film set tomorrow for a full day of Steadi, (on Alexa : D ) Thanks for all the comments and suggestions!! Steven
  2. Hi Guys, Sorry for the EXTREMELY late reply. Post Productions in 4days, so I'll let you know how I go. (more controlled test e.g. no wind, or rushing AD's ;) QUICK QUESTION: Having a preston MDR mounted under the front of the junction box/electronics, does this affect how far back the camera cg. should be from the post? Does this make sense? (I plan on taking some pictures in post, maybe a video or two) Thanks Steve
  3. Hey guys, Thanks for the speedy replies, Victor: I believe the goal is balanced, but will check again today. Thanks Jerry: Page 12 you say... Just before I threw up this post I printed out page 12!!!! : ), but read the primer several times last night trying to get my head around the maths too, Im about to head into work and follow it step by step. Great work, nice website! Thanks Bryant: I too instantly figured that whilst testing the drop time after the initial static balance that leads and accessories may have shifted causing my problem, (I am using a RED!!!!!) subsequently I de-rig all cables and Velcro items from the camera and started again and the problem still occured. Thanks Alan: Our gimbal was slightly out, but we have corrected in pre for the current film we're working on. Thanks Im about to head off to work, and will check the goal/gimbal and rig the camera without leads and then walk through a balance whilst reading page 12. Will let you know how I go. Thanks again Steven
  4. Hi Guys, I work as a 1st with the same Operator and we've noticed a problem has developed in obtaining a Dynamic Balance, would love to know if anyone has experienced or heard of this before, and open for all suggestions to fix. After a buy the book setup is complete, achieving good monitor position, drop time and Static Balance we then proceed to spin and/or drop the camera side on to test for dynamic balance. Once the Dynamic balance has been achieved, the camera will always rest in tilting up position. So we Re-Static Balance the camera which in turn always creates a monitor(fore) heavy Dynamic Balance. No matter what combination of battery in, monitor out, camera forward or back, drop time, etc.. you can only obtain a good Static balance with a monitor(fore) heavy dynamic balance OR a good Dynamic balance with the camera resting in a tilted up position. Interestingly the tilted position seems to be fairly consistent without putting an inclinometer on it. Also we have tuned the gimbal to take this out of the equation. Thanks Steve
