Shooting offroad race for tv production. Everything is real time 30fps. Not sure if I need to overcrank shutter or just shoot it 30fps/60shutter. Using wide lens with Tyler mount Mini Gyro. Can someone give me an idea of what shutter speeds I need to use? I think I understand but wanted other opinions and didnt want to blow it. Thanks!

You say that the client won't use overcranked footage but then you ask how much to over crank. Do you mean what shutter speed should I use?
If this is the question, then I wouldn't really go above 1/90 sec.
an easy way to figure out a "natural" look for over cranked footage is to take the frame rate e.g. 96fps and double the number for the shutter speed. So you end up with 1/200.
As for sound, you will get nothing usable from the onboard recording in a helicopter.
The tyler mount also needs a good amount of time to spin up to speed - I think that it's 20 minutes or so.
Above all, be safe and you may want to bring a wider lens with you.

Yes sorry I contradicted myself. I always double number. But I wasnt sure since I was in heli if I needed to go beyond that. So should I stick with normal. Shooting 24fps with a 48/1 shutter?
 
Wider lens for sure

Wider lens for sure

I have shot a few times from a helicopter with my epic, and for sure you should think about a wider lens, and for sure slow mo...and no way will you get any usable sound.

Lets just say it wouldn't hurt to use a higher shutter speed but it will create a different look. See how far you can go without spotting it.
Also, if you can, do not use a mattebox. Use screw on filters instead.

If you are going to do any post stabilization, a higher shutter is going to help immensely. Otherwise post stabilization footage with motion blur looks terrible.

To be honest. I don't think they are going to stablize it.

Made it little easier to understand.

BINGO! If you're anything but super wide, this just might save someones ass!
 
I was in the same situation this summer and decided to go with 48fps & 1/96 shutter speed, to give myself some safety. Footage looked great and adding some additional stabilization in post worked well, although it wasn't necessary on every shot. I used the RED 17-50 and kept it on the wider end. At 50 it was pretty difficult to get smooth shots.
 
i would shoot overcranked atleast 48fps for 24p finnish. The overcranking saves you from rolling shutter issues in a way shutter speed does not. So instead of shooting 90deg shutter instead of 180 You actally get a better material shooting double the frame speed. If i'm not completely mistaken... But my lasts half ass test showed that shutter speed does not save you from rolling shutter, framerate does... Then in post you can "deal away" / timwarp without interpolation so you get down to realtime... but what TV show does not want slomo if it's offered to them as a bonus.... :)
