Just a note, to save you a take or two, if you plan on shooting anything with automatic weapon fire: we had a large amount of drop frames at the moments of firing with automatic weapons. They were blanks of course, but still very very loud. Our solution was CF cards. Initially we were on RED drives and basically got dropped frames whenever the weapon was really laid into. Small 2-3 shot bursts were ok, but anything with like 5 or above automatic fire would start dropping like crazy.

We had shot several days with pistols, semi-automatics, squibs, wall hits, gasoline explosions, etc. and no problems on the RED drives.

In short, if you are doing automatic weapon fire, I suggest going solid-state.

Happy New Year!

P.S. Test your blanks. Ours were throwing out a lot of smoke and powder and were covering up our subjects after only a few bullets.
 
Thats a AK74, shots a smaller round the the 47. Cool assault rifle though

Wait- are you asserting that the force of the weapon actually affected the camera and caused it to drop frames or just that you missed the action of the gun on certain frames because it was too fast?

That the noise caused drop frames
 
This is a known issue with the Red Drives; loud percussive sounds vibrate the drive and cause dropped frames.

It's been reported with shooting music videos and, in my case, shooting a large lightning machine in a science museum.

The solution is recording to the CF cards.

Good shooting and best regards,

Leo

Precisely...
 
Just so we can clarify the setups.

Were the drives mounted in the Redcage in all of these instances, or was it dropping frames with third party solutions like ET shockmount? This would be good to know for those who may need to put the camera on shoots like this in the future.

Mine was in the RED cradle when it was dropping frames from an AR15 being fired inside. Even with earn protection on it was still really loud. That would be the real test of the ET mount, if it could keep from frames skipping in that type of environment. Personally I don't think so because of the nature of the concussion but I guess tests are needed.

I can test this with the shock mount. I have access to a firing range. I also have access to a mortar. I've wanted to do some hi-speed tests with guns anyway. As soon as my camera is back, I will do this.

I look forward to seeing your tests and how the ET mount holds up to that type of beating.

Keep in mind that if the concussion is big enough your drive's heads may make contact with the platters. This could result in destroying your drive, or just leave you with a drive that will fail unexpectedly in the future.

Good point. :sad:
 
Besides a sound blanket of some sort on the camera itself you can put vibration isolation cups under each tripod leg. These are used on telescopes to dampen vibrations which can cause fuzzy imaging.

Wow that is a lot of smoke! Good to know about the quality of blanks. We are about to test a bunch of blank firing guns over here. Were those a local Kazakh brand?

I'm sure they were. I've never seen a real or fake bullet throw out as much smoke as these things were.
