Problem with V1P - audio drop outs and "jump frame" during pan shots

Hi all,

We are shooting a mini series here in ShenZhen China and have recently "upgraded" our production camcorder from the Z1U to the V1P (pal version of V1U). Things have been working well until two major problem arose:

1. Audio drop out problem.
- The audio through the XLR inputs continuously drops out. The drop out occurs independant to the type of microphone used as well as the channel configuration set(Ch 1, Ch1 + 2 etc.)

We've tried quite a few different microphones from the package shot gun, to a Sennheiser ME66 (both phantom powered and using the K-6 power supply), to wireless mics (a set of Letrosonic 400, and the Sennheiser EW100) and the audio still continue to drop (ie the audio would come in fine but suddenly disappear).

This problem is resolved, however, by turning the camcorder off and then on again.

We are also seeing a change in this problem in that instead of "silence" drop out, we are starting to get a lot of hiss and static noise through the input channels. They are coming in quite loudly too, but they go away again when the camcorder is turned off and then on.

2. "Jump frame" during pan shots

At the end of a pan shot, the frame would "jump". This occurs around every third pan shot. This can be seen both in the LCD as well as is recorded onto the tape.

The "jump frame" problem does not occur during hand held shots, however. Just when the camcorder is on stick and the pan is slow.

The serial # of our camcorder is 1310135. We've got a loaner now from a local rental house here in ShenZhen, and it seems that the rental suffers from the same problems.

I'd be interested in getting any feedbacks from other V1 users especialy those who are using the PAL version.

Any suggestions / advises are appreciated too.

Thank you!
MK

Hi Michael,
I don't have the V1, but the second problem sounds a lot like the image stabilizer has been left on - try turning it off when using a tripod for pans and tilts.

Cheers,
Kyle

The audio problem sounds like an over active limiter. Do you have the audio limiter on? If so, try turning it off and see if the problem goes away.

Jump frame

I postet this some days ago:
__________________________________________
This morning I got a HDMI cable and connected it with the HDMI out of the camera and the HDMI in of a new HD-TV.
Then I focused an about 2 meter distant object.
A full zoom shot, adjusted the picture, with extended focus, as sharp as possible. Then I went and watched the picture on the new HD-TV. Picture is super, but ..............

Camera stands on a tripod; head is firm, no wind, since it is indoor.
Although I stand about 4 meters away from the camera, the picture on the TV doesn’t stands still. It moves vertically up and down, up to one centimetre. Only vertically, not sideways.
First I thought it is an earthquake or the house is shaking. (haha)

After I switched off “Steady shot”, the picture stops moving up and down.

On tripod, NEVER use Steadyshot.

I programmed a Assign-Button "Steadyshot ON /OFF
