Hello,
I did my first shooting with a recently acquired HVX200 and I am experiencing some weird image problem. I did some test shot of urban landscapess. When I zoom or pan,
Many lines seem consisting of broken moving line segments or as if some waves are passing through them. I am wondering if you have had similar experience. I suspect the camera is defective. They are shot in NTSC format on miniDV tapes.

You comments are appreciated.

If you're shooting interlaced, it could just be interlacing artifacts. Try shooting progressive.
Can you post a screenshot/clip?
 
I am not sure where I can post a file size of a few mega bytes (3-5mb). Can I send it to you by email?

If it's about interlacing, it might be possible to fix it by converting it to progressive in Final Cut Pro, right?

Thanks, Ramin

You might have luck by removing interlacing. But you can shoot progressive next time so you don't have to deal with it.
 
You must be right about the whole issue being related to interlaced recording. When I export the file in FCP using Quick Time conversion into a progressive video (deinterlaced), the artifacts are mainly gone (just very little remains)! When I export it without deinterlacing, they are there in the output!

Can you tell me what your settings are for the following options (in order to record and be able to see the standard time code data that is hour, minute, second nd frame rate)?

TC MODE
Options: DF, or NDF

TCG
Options: FREE RUN, or REC RUN

FIRST REC TC (TAPE)
Options: REGEN, or PRESET

UB MODE
Options: USER, TIME, DATE, TCG, or FRM. RATE

UB PRESET ?


Thanks, Ramin


 
DF or NDF is your choice, but if you want the timecode to reflect the actual running time of the footage, choose DF.

For TCG, if you want it to represent the time of day use FREE RUN, if you want the timecode to advance only when you're actually recording then press REC RUN.

For First Rec, if you use REGEN it'll start over at 0:00:00:00 whenever you put in a new tape, or whenever it sees a blank spot on the tape. PRESET will always start the timecode at the point where the last recording's timecode stopped.

For UB MODE, never change away from FRM.RATE unless you have a very good reason. Leave it on FRM. RATE.

If you've left it on FRM. RATE, then UB PRESET has no effect.
 
OK; thanks for the input. I still see that sometimes the camera can not communicate with the tape for registering or displaying the timecode. I could stripe one brand new tape, and when I play it back, I see the timecode progressing. I try striping another brand new tape and the camera does not register a timecode on
the tape!
