  • I was very glad to see this video. This topic can be confusing for those, like myself, who are very recent to the RE video skill set. And it had seemed to me that the 180 rule (shutter speed twice the frame rate) was set in stone. And for those of us trying to master this alternative to stills, especially when shooting video with the same drone that we are using for stills, just how to make our settings for the optimum results is still a challenge. And it then necessitates the use of ND filters that do the same thing for video that they do for stills but many times with a different end result in mind. Such as with the Mavic Air, if anyone is trying to use it for RE video. Unlike its larger cousins, it is set at f-2.8 and you can only change the ISO and the shutter speed to manage exposure. Not a problem for stills but if you are limited to either 1/60 or 1/125 of a second for video at f 2.8 it can be tricky. So you need ND filters to bring that shutter speed down to where you need it if you are shooting in bright sun.

    Makes steam begin to come out of my ears since I don’t have a technical mind. This video can help those of use new to video to remember some of the basics.

  • I usually shoot at 30p. I’d love to shoot at a higher frame rate, but like many of you, my cameras have limitations when shooting 4K. But, there are ways to cheat it out to achieve smooth slow motion. It’s very easy.

    I use Premier, so I’ll give the cheat for Premier:
    1- Right-click on the clip you want to stretch and choose Speed/Duration
    2- Give it a new duration length, and hit ok
    3- Right-click on the clip again and choose Time Interpolation, and then choose Optical Flow
    4- Hit the Return key on your keyboard to Render the clip, Presto Done!

  • I shoot 30 fps because this is what Zillow accepts.
