JD Hartman Posted February 6, 2017 Share Posted February 6, 2017 I don't think the details of pyrotechnics and their application should be discussed on this board. If you have to ask, you haven't been trained in their safe application and you shouldn't be using them. Hire and consult with the appropriate specialist. http://www.motionpicturearmourer.com/q10.htm 1 Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted February 6, 2017 Premium Member Share Posted February 6, 2017 Sparks are usually either squibs (small planted explosive packets triggered by someone) or "zirc" hits, a type of pellet fired from a special gun (usually from off-camera) that sparks when it hits a hard surface. As JD says, these things are done by trained, licensed professionals and can be dangerous. The falling shot of Hans Gruber required a high frame rate camera shooting down at the actor falling into a large blue screen covered stunt pad, and the composited over a plate. The explosion was done on a very large miniature. 1 Link to comment Share on other sites More sharing options...
Mathew Collins Posted February 7, 2017 Author Share Posted February 7, 2017 (edited) Thank you Hartman and David. I was just reading this link. https://medium.com/cinenation-show/cinematography-greig-fraser-asc-acs-25a087e46af4#.vadjhou6o Here Greig Fraser is explaining a technique he used in 'Killing Them Softly'. I am not able to understand it completely. I think he used LED light-strobbing to give gunfire effect. Does someone have any information about this?

Premium Member David Mullen ASC Posted February 7, 2017 Premium Member Share Posted February 7, 2017 He created a flash using an LED strobe. Link to comment Share on other sites More sharing options...
Mathew Collins Posted February 9, 2017 Author Share Posted February 9, 2017 Is the that effect used to create Gunfire effect? Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted February 9, 2017 Premium Member Share Posted February 9, 2017 Is the that effect used to create Gunfire effect? The article isn't clear but it seems the strobe was just off-camera to create the lighting effect of a muzzle flash onto the subject. This is not unusual, I remember reading about an old movie, maybe "The Emerald Forest", where a nighttime sequence with gunfire was mainly lit with strobe flashes. Sometimes multiple flashes from strobes during a gun battle can make it seem like many more people are firing guns from off-camera. Link to comment Share on other sites More sharing options...
Phil Connolly Posted February 9, 2017 Share Posted February 9, 2017 You can create quite realistic muzzle flash using After Effects plugins or the built in tools. But you still need flashing lights strobes or similar on set to really "sell" it. Since the muzzle flash would be illuminating the set briefly - a give away on bad cgi muzzzle flash is when the lighting on the set doesn't match up with the flash Link to comment Share on other sites More sharing options...

Edward Lawrence Conley III Posted February 9, 2017 Share Posted February 9, 2017 Strobe for in camera sell f the gunfire and FX in post for the muzzle effects "when Pitt pulled the trigger the strobe light duplicated the characteristic flash of light as the gun was fired (the muzzle flash itself was created in post production)."

timHealy Posted February 11, 2017 Share Posted February 11, 2017 I hate to date myself but it reminds me of edition of Cinefex: http://www.cinefex.com/backissues/issue36.htm But as far as weapons are concerned it seems only props who have a special movie/tv license can rent them from weapons prop houses who also have a license. Its very regulated as it should be. I looked into it years ago when I was doing something for myself. Weapons Specialists in NYC is one. But don't do it unless you have a professional with you who will keep everyone safe. 1 Link to comment Share on other sites More sharing options...
