How much of a disaster is this?

I just realized I shot my entire feature at 25P using the non standard shutter speed of 1/100. That will give me a lot of strobbing. How muchg of a disaster is this? I feel pretty bad about it. What can I do to limit the damage?
 
Limit the damage? Too late for that. How much of a disaster is it? Only you can determine that.

I've made mistakes. Just found I made a HUGE one this past weekend on a shoot. I'd like to call for a re-shoot, but don't have that option available.


Mistakes happen to us all sometimes.
 
It's a disaster if it's not what you wanted the footage to look like.

There's not a great deal you can do about it without going frame-by-frame (in which case, you'd have to treat each frame as a still photo), and even then it'll be a LOT of work per frame to get to look decent.
 
Well, here's the big quesiton -- how do you feel the footage looks? If it looks good to you, then it really doesn't matter whether the "correct" shutter speed should have been 1/50th. It sounds like you're scared of how it might turn out, but haven't actually reviewed it yet? Definitely sit down and watch the footage; you might find out that it looks okay, or you might not be happy with how it looks.

If you're not happy with how it looks, you can try rendering out the footage in aftereffects or something, adding a motion blur filter to it, to smooth it out some.
 
Motion blur FX don't normally work for straight footage; they're for blurring layers you add your own motion to, or for generated FX like page-curl transitions. Doesn't hurt to try, of course, but they won't (generally) smart-add blur to moving objects within a self-contained frame.
 
what you need is really frame blending between the 2 adjacent frames to add some motion blur transition between the frames
 
It's not typical of film-looking footage. Typically a film-style shutter would be around 1/50th, ranging from about 1/43 up to 1/60th. So, yes, 1/100 is quite abbreviated.
 
Mbala whats your feature about? The subject may go a long way to making it work, or making it need a fix. As Barry said, review your footage.
 
how was it not noticed that u were on such a high shutter? nobody noticed the light loss, more video like movement and so on, for a full feature worth of shooting?
 
I don't think the shutter speed will be the make or break on your film. It certainly is a nice touch, but I don't think it'll hurt you too much. I shot most of my feature at 24p 1/48th, but other parts I purposefully shot at 1/1000 to get an extra sharp look. It doesn't look filmic, but it certainly doesn't look bad.
 
If it has a good story....then I wouldn't worry too much. Heck...I sat through "Crank 2" with its crazy high shutter speeds and as far as story goes....it wasn't exactly Oscar material. So....don't worry about it.
 
The movie is a musical. I just assumed the shutter was set on default. I was wrong. The footage looks watchable but I get the feeling the strobbing is excessive, expecially on closeups and movement shots. I just don't know how far off the deep end I went with a 1/100 setting for the entire movie.
 
I wonder what it would look like if you exported the footage from your NLE at 50% speed with frame blending, re-imported the footage, and then played it back at 200% speed.

I'm guessing it looks terrible, but it's probably worth a test.


You're best bet is probably telling everybody that the shutter speed was the look you wanted and moving on.
 
There won't be as much motion blur, that's it. If you were shooting on a CCD camera, there would be a bit more vertical smear, but CMOS cameras are immune to that. It shouldn't be a problem for the audience, although it could give a look that you weren't going for or that doesn't exactly fit the context of the movie. But if it really were a problem for viewers, why would companies bother making their cameras able to go as fast as 1/1000?
 
I've got one also from last week (going to post it later). May cost me thousands for the reshoot if I can't fix it. Just gotta take a deep breath, walk around the block, a say to yourself "but I'm still alive"... We all gotta just have a good cry once in awhile...

for future reference if you shoot with a Shutter Angle of 180 you'll never have to worry about this ever again.

Well, then he was shooting at 50p shutter speed... just the frame rate was wrong...

But unless the exposure was off by a stop, and there's motion, such that the 1/100th sec. shutter speed does 'strange' things to the motion, there may not be much of a problem at all...
