Sorry I can’t give you specific shutter speeds to stay within. Most people don’t even notice - just don’t do it on an important shoot haha. I’ve been on a few shoots over the years and forgot my ND filters so had to rely on shutter speed to control exposure - shooting as high as 1/4000 outside on a bright day. I’ve found that you can still shoot at faster or slower shutter speeds and capture great looking footage as long there isn’t a whole lot of fast moving stuff going on, so I’m guessing you’d be safe to break the 180° rule in a museum.
For example, if you’re shooting something with a lot of motion and you plan to extract still images from the footage as well (something our clients ask for all the time so they don’t have to hire a photographer haha), you might want to shoot at a faster shutter so every frame isn’t totally blurry. With that said, there are times where it makes sense not to shoot at 180°. The reason the 180° rule exists is because most people find the amount of motion blur at 180° to be the most pleasing - it’s totally subjective.
Faster shutter speed will give less blur, and slower will give more. Thanks for connecting! The only thing your shutter speed will affect is the amount of motion blur in your footage. I noticed the link in my article wasn’t working. Here’s an updated link to Red’s shutter speed/angle calculator. Here’s a great video explaining shutter speed vs angle. If you shoot any 25fps, a shutter speed of 1/60 would be best. If you’re in PAL mode at a US airport, a 1/120 shutter speed will work perfectly for 50fps stuff.
Flickery thoughts tv#
As far as I know, there aren’t many issues viewing PAL content on an NTSC TV but it’s something to consider I guess.
If you shoot any 24fps stuff, you would use a 1/50 shutter speed (172.8-degrees). if you shoot at 60fps, use a shutter speed of 1/100 (216-degrees). However, if you want to be able to watch the final video on your 60Hz TV then you might consider shooting everything in NTSC mode and just changing your shutter speed accordingly, i.e. If you’re planning on just throwing the project on Youtube it would be easiest to shoot the whole thing in PAL mode since Youtube takes both NTSC and PAL. This is one of the contributing factors to the popularity of 50Hz. If the frequency is sped up to 50Hz, the flickering, although still present, goes unnoticed by the human eye. But, to provide some perspective into it, certain lights tend to flicker when a low frequency current is run through them. They were chosen for very specific reasons that go beyond the scope of this blog. It’s worth mentioning, 50Hz and 60Hz are not arbitrary frequencies. Each region established its own monopoly and the rest is history. At the turn of the 21st century, to avoid competing with one another, manufacturers in America focused on producing 60Hz equipment while manufacturers in the UK focused on producing 50Hz equipment. Why? There are many historical factors responsible for this divide but, in a nutshell, it comes down to economics. While in North America, and a few other countries (Japan uses both), the AC frequency is 60Hz. In the UK, Africa, Australia, most of Asia and Russia, the frequency of AC (alternating current) running through electrical mains is 50Hz (Herts).
