broken timecode / cam rewinds a few seconds

:-/I recently shot a short drama with the dvx100a. i liked many things about it. this is the third shoot with the camera. (i don't own it, i am a cinematographer/videographer for hire)

My problem. The editor has told me he has some time code 'jumps' where the timecode skips a second or two. No black. just a jump in time code during a take that prevents the pre-roll on the avid from successfully batch capturing that clip.

ALSO, we had 2 or three occasions where the camera apparently rewound slightly and taped over the tail end of the previous shot. This was most obvious on one take where the shot ended and after slating the next shot and waiting for the actors to get ready (recording what in film would appear to be an MOS slate snce sync is not an issue) the continuity person noted a stange timecode issue....We seemed to have gone back in time. I rewound and watched the footage and, sure enough, there is the previous shot interupted by the slate and then followed by a second of the very end of the last shot. hmmmmmm

Could it be that i am powering the camera down too soon after I stop recording? Or even starting the recording too soon after powering up?

There were a few instances during the two day shoot where I thought the camera had a mind of its own as it whizzed and whirred so many times in a row it sounded like it was a little confused... having some trouble wrapping the tape around the heads or some such thing.

Any body have any experiences similar o any of the above?

Sid: me shoot. you like.

Sid,
Sorry I will not be able to help, but I predict that others will request more info about the cam.
They may ask about time code settings used, brand of tape used and if different brands have been used. Could be asked for total hours on the heads or other info about past problems/service . If you can supply any more info which you believe could be heplful, you'll likely get a better, quicker result. Good luck!

You will get breaks in the time code after a powerdown/battery change etc. There's one easy thing you can do to always avoid these breaks. Before every new take (or as soon as the camera has been powered down, you have changed batteries or rewinded to watch the last scene) you press the "rec chk" button (located above the rec button). This will make the camera back up a few seconds, play them back for you so you can see exactly where on tape you are (so you know you start at the right spot), and while doing this the camera will also pick up the old (last recorded) timecode and resume it once hitting the rec-button again.

As long as you do this you should be fine regarding breaks.
Keep in mind though that the camera will always start recording at the current position on tape, which means if you rewind to check a previuously recorded scene you will have to manually go back to where you want to start recording and then hit the "rec chk". If you play back the last scene longer than you recorded it (tape is blank, the time code freezes), you will get a break in the timecode. So make sure the new starting point is always on a previously recorded frame. Thumb rule, always record a minimum of 5 seconds before and after every take.

Also make sure you are using REC-Run and not FREE-Run for the TC. How to setup this can be found in your DVX100 manual.

Good luck!
 
Re: broken timecode / cam rewinds a few seconds

I'm having an exact same issue with camera reloading the tape intermittenly. I even brought it to the shop for that. They saw it when I brought it in, had it for three weeks and returned it to me saying they couldn't replicate the problem. It IS intermittent, but I never went through a tape with it not happening at least once. It usualy doesnt start until you are a few minutes into the tape. I also never have any problems while recording -- no dropouts or anything, it only reloads while in standby. Really annoying and I lost a few shots because it takes about 30-40 seconds to do that and you can't start shooting during that time. Heads have been cleaned at the shop while they had it.

I still have half a year of my warrantee left, but don't want to take it back to the shop since they don't seem to be helpful.

Any ideas anybody?
