Flickering is a constant struggle for bullet-time systems. Here are a few tricks to reduce or even eliminate flickering.

What causes flickering?

What are the solutions?

  1. When using flashes The best solution to avoid flickering is to use strobes / flashes / speedlites. This is what I did in this example: [https://www.instagram.com/p/Bxipx5rFswp/.](https://www.instagram.com/p/Bxipx5rFswp/)However, even with flash, you might get some flickering if the light is strobing too fast. Your best option with flashes is always to use a 1/60s shutter speed and a longer duration flash. When using legit Canon 600ex Speedlite, you are 100% sure of never having cameras that are missing the light as the flashes are slow enough to cover the whole exposure. But when using super-powerful lights like the Profoto D2 1000w, you are going to see flickering if you use the light at a lower value. The reason is that these lights are not dimming but instead, they play with the duration to provide more or less light. When you go to 100% power, then your flash lasts just long enough to get picked up by all cameras. Why is it always a better solution to use flashes? By doing this, you are not relying on the physical camera shutter, but instead, it's the light that syncs the subject. There's nothing faster than light, right? :)
