p.1 #1 · X-S20 - Does 180 deg shutter rule still apply when lowering frame rate on timeline?


Hey ya'll,

Total hobbyist here trying to get back into video after a decent hiatus. My workflow has always been shooting at 4K 60fps and then converting my normal speed footage on the timeline to 24fps.

The reason I've done this is because I shoot mainly travel videos and half of my timeline is slow-mo shots where the 60fps really shines. I've always done this on my gopro but recently upgraded to X-S20 where I can now shoot manual and accomplish a bit of cinementatic motion blur with the 180 deg shutter rule.

My question is if I continue to follow my workflow of shooting 60fps with a 1/120 SS to satisfy the rule, should my cinematic motion blur be retained or am I wasting my time because it gets erased on the timeline when lowering to 24fps?

TLDR: Does 180deg shutter shutter rule work on footage thats shot at 60fps + 1/120 SS, lowered to 24FPS on the editing timeline

Im not really sure what you are asking-

You are talking about shutter angle being set to 180 degrees- The xs20 doesn’t support that-

I would still follow the rule of double your shutter speed If and huge if here that you can support it and get the exposure you need.

I think its worth it to do but it does require a heavy usage of ND filters for anything outdoors since bright light and 1/125 shutter speed isn’t always easy to achieve, Espcially with bright apertures.

Your footage will look better in the long run but it’s not always worth it depending on the video you are creating based on always fussing with ND filters.

For creating great home videos, I find something with a built in gimbal much better (DJI OSMO Pocket) or something along those lines more important than getting the perfect shutter speed. That and audio-

Good Luck

Hey thanks for the reply. I should've added that I actually have an NSI ND that can go up to 9 stops I agree that the ND won't always be convenient but I think im looking for the challenge and to start learning how to color grade in davinci.
