I manage the student equipment services at UCLA. We have a student shoot in El Paso and I just heard from the DP- "just went through Day 3's dailies and there is one take out of everything that that is suddenly possessed by 3 seconds of pure gray. We never saw it during filming. Never saw it in camera, but it is on the red drive, all backed up proxies, and the log and transferred into FCP footage...concerned it can be a capturing issue...any idea what it can be?" I did a cursory search using the terms Gray and Problem but so far I'm not seeing anything. Any help would be appreciated. Thanks in advance.

Those would be dropped frames, which you don't see happen, but the camera will notify you of the dropped frames on the lcd down at the bottom. That can happen when using the red drives. I have had it happen when the drive is unmounted and remounted without dumping footage. Sorry to hear that.
 
Were there loud noises or music on the set? Gun shots? Explosions? These can cause dropped frames recording on the Red Drives.

I don't believe anything can be saved as it was never recorded in the first place. Sorry.

Good shooting and best regards,

Leo
 
I too have power cycled with a drive, although I do try to unmount first. I confess I've even had a few "roll-outs" with the battery failing and I've never had dropped frames except for noise in recent builds.

Good shooting and best regards,

Just from my experience I have noticed that if i unmount a drive and remount with footage still on it without dumping and reformatting, that is the only times I have noticed getting dropped frames. When I reformat every time I never have an issue with dropped frames. Thats just my experience for the past few years shooting Red Drives. The AC should always be on the look out for dropped frames when shooting, when the take is over it will keep the notification up till the next time the camera speeds.

Good Luck,
Ross
 
But if you haven't dumped the footage you wouldn't know if you had dropped frames or not as you haven't see the frames play. My guess is they were dropped from the moment you shot and you didn't notice the indicator.

Dropped frames can also occur from camera shake or bounce. If any of the shots were in a bouncy environment of any kind, this could explain it.

Or obviously a media issue could cause it as well.

If it can't be repeated then probably no reason to worry. Just keep your eyes open for any issues that could be related.
 
I guess I am not making enough sense. The dropped frames happen on the shots taken after the remount. And the lcd will tell you if you had dropped frames on the last shot, or while shooting the shot. The drop box next to media and battery level box at the bottom will go red and start showing the number of frames dropped. Hope that makes sense, nothing you can do about it now, but you can prevent from missing it in the future. :smiley:

Thanks for the additional info Ross.

That's really weird. I have done this hundreds of times (mount, remount without dumping/formatting) and have never had a dropped frame as a result.

I typically don't do it while the camera is running, but have in the past without incident.

My disk bouncing comment was for Albert as everyone was just talking about loud sounds causing dropped frames an no one mentioned vibration. :badputer:
