agolex Posted November 22, 2015 Share Posted November 22, 2015 Does anyone have insights on what kinda fps you need to film crash tests and such appealingly for the industry? No super high profile, but decent. Is 120 enough if you mess around with it in post?Thanks for your input! Quote Link to comment Share on other sites More sharing options...
Nikkor Posted November 22, 2015 Share Posted November 22, 2015 I think besides fps, shutter angle is also important or even more important. 1/1000 is probably the minimum you want, but I guess the fastest possible will give better results. I might be wrong because I have no insights, but in photography you would go the highest shutter speed possible so you can see what's happening, not just some blurred mess.

Hans Punk Posted November 23, 2015 Share Posted November 23, 2015 Depending on what you want to shoot, 120fps is a good speed for human action speeds (running, jumping etc). A newer model iPhone can shoot 120fps burst and is often useful to use as a viewfinder for judging high frame rate speeds for other cameras. (Or at a pinch, be used for the actual shot).But if you are talking about crash test type shots, 120fps is often not always slow enough...500-1000fps + is more common to catch the frenetic split-second details of things smashing, cracking, exploding etc.araucaria is right about shutter speed, if you can't reach your ideal frame rate - you can dial up the shutter speed to get each frame as crisp as possible (reduce motion blur) and use Twixtor or similar plugin in post to do a post retime to slow the footage down further. This can work well for some shots, not others - as the artefacts induced by interpolation of frames can cause ugly results if pushed too far. In general though, good results can be obtained if no/low motion blur is in your footage.here is a visual overview vid on frame rate speed results on a flex:http://youtu.be/tcQ37OfknJA Quote Link to comment Share on other sites More sharing options...
