16mm grinding sound
Posted 15 December 2006 - 09:52 PM
Now I am sort of worried, some shots theres that grinding sound during certian points. Its not consistent, sounds like something is rolling. Does anyone know what sort of footage I should expect if the shutter did have an error (is it slight, or completley rubbish?) if anyone has a pic of this error presenting on a CP-16 it might ease my mind.
If its slight and looks like it does in some music videos, I might be alright. In fact, if it looks the way I think it might, it might make the movie really great (its that sort of story where it would make sense). It only happens at times that I would have wanted the effect, if it were planned. Some scenes it can be cut around, some it can be cut between it happening and not for emphasis.
I can correct the audio and pull out the sound....im just worried about the film...I assume I will get smeared highlights if its the problem I am thinking of, I am just not sure how far off the timing could be. if its by a lot, then I would assume highlights would smear sooner (at lower levels) and have a stronger effect, if its by a little then maybe only the specular highlights and practicle lights would smear. at least it didn't happen in any of the EFX shots. This is weird because the camera teched out fine. any help would be appriciated

In the end its in so few shots that I can cut around it if I like it, I just am mad I didn't hear it on set.
It wasn't from loosing a loop, we lost the loop only once during the shoot, and it was very apparent when that happened. this is very suttle sound. Maybe grinding puts too much emphasis on the sound.
At this point though I am trying to find a way to bring in the glitch as a story element, by augmenting it at certain points and using editing to bring it forward when the story warrents it, and out when it should be more straight forward. Maybe time away from seeing the film is giving me time to drive myself mad by imagining problems.
Ryan, is there any way you could post a single frame shot of the smearing, just to give me an idea?

One guess is that it's a bearing just starting to go bad. Bearings will often develop an intermittant "moan" when they're just starting to go south. If that's what it is, a good lube might solve the problem for good.
.........Its actually quite soft grinding.
