Question

A different kind of strobing problem

I am attempting to capture to video a multi-image slide show. This show uses 15 slide projectors pointing at a single screen area. Occasionally the slides run by at 10 slides per second, with a "hard cut" transition between them. When one views the show projected live on the screen it looks great. HOWEVER when the show is captured to video there can be a very evident "blink" in-between each frame.  I suppose that persistence of vision can't cover everything.... Anyway I am trying to learn if there's any to "fix this in post". Please take a look at this under-10-second, 60 fps clip that illlustrates the problem. https://tinyurl.com/22m9xrhm

Hey Steven,

I agree with Ann. With your Timeline selected, please go to Sequence > Sequence Settings and set the Timebase to a lower number. Let us know how it goes.

 

Thanks,

Ishan

that was a good thought, but it hasn't sorted out the problem.  Here's the new file after changing the sequence setting and the output to 24 fps.  https://tinyurl.com/4ccpw6fd

In the 60 fps timeline the 10 images are each 6 frames long: this will give you a kind of stop motion effect.

Images need to be less frames in duration.
