Hey-

So we;ve been mandated to shoot at 1080 now by our owner but i seem to be getting this pink flashing line in the upper lefthand corner. I first noticed it when we did some greenscreen which was an easy mask out but now im noticing it on my studio stuff, which is kinda getting annoying.

Any idea on what could be causing this? Is this something to send back to Panasonic to look at? Check out the two screen shots and let me know...The first one has the line

This is a phenom that keeps people posting questions. The folks at the top of the food chain here at dvxuser ignore it and deny it exists. Is it a defect or is it just one of those camera quirks that Panasonic knows about but won't address?
I suspect they know and don't care.
 
Nobody "ignores" it, I blame it on fCP. I've viewed 1080/24pA footage in EDIUS, in Raylight, and in Premiere Pro cS3 and I haven't seen this. Therefore it leads me to believe that FCP's pulldown removal is making this happen.

Windows...sp2 and sp3 and Vista sp1. It's not pronounced in every shot, but can be quite noticable. Once you know it's there, you watch for it...that's the nature of a visual blemish. You had mentioned defects not normally seen because of overscan a while back...every lcd screen I have seen of late seems to display the whole image.
 
lines in premiere cs3 windows frame grabs...not as good a grab as scynda, but the line is there

The bulk of the Sound DVD consisted of about 40-50 16GB cards' worth of 1080 24p footage from both the HVX200 and the HPX500. Working in Vegas with Raylight or CS3 -- Premiere or After Effects -- I never once saw a pink flashing line.

I just looked through about 35 random clips and it was not there on any of them.
 
Well, with that said, I can only assume my camera and scyndas are defective. Now I don't know when scyndas camera was purchased...but I can tell you I'm not a happy camper to have helped Panasonic clear the old stock hvx200s just before they introduced the hvx200a, and gotten a damaged camera to boot.
 
Since your camera is allegedly defective, it should always produce the problem, right? Can you post a link to a small 1080pA clip in its original MXF format (not a QuickTime container) so that we can check it out? Also please verify that it exhibits the problem after you load it into FCP/FCS before you upload it.
 
I've sent a 5 meg segment of an mfx file via email...you get two or three flashes. For those watching this discussion without benefit of the mxf file, all you see is what the previously posted frame grabs show. If it was video recorded on tape, I would say it looks like the head switching glitch you would see in a crt overscan area. I've got a couple of desktop machines and a couple of laptops (all with lcd panel displays of course) and the flash line is present on all.
Now it's possible that lcd panels are supposed to have overscan (mine don't) and that would keep the line from being seen. I dunno.
In searching for online references to this issue I came across an extended discussion between an individual and a Panasonic representitive concerning the hvx200, green screen and a black border/shadow.
This exchange of views was in depth and lengthy...and nothing was resolved. I'm not going there...life is too short. If a solution can be had for the flashes, great. If not, I guess 720 ain't that bad.
 
This has happened on over 5 cameras I have tested -- has nothing to do with the NLE may have to do with Mac OS X -- I have no way to test for this.

We had to zoom in an entire film because of this to pass Quality Control on a film. It happens to my knowledge only in 1080 24pa and is viewable in the original MXF file (before wrapping to QT). It happens every five frames on the BB frame.

The easiest way to 'see' it is to shoot a dark scene with a bright object. A candle burning in a dark room would be perfect. Tilt the camera up and down dodging the flame in and out of the top edge of the frame. Watch the footage. On every BB frame you will see the problem. Basically the camera is writing 3-4 pixels from the AA frame onto the BB frame.

I have yet to see any footage on a Mac that doesn't produce this artifacting. Can anyone see this on a PC [edit: Noticed you are on Windows -- I'm convinced this is a camera issue]????

It seems to me that enough people are having similar problems with 1080 24 pa in the hvx200 to point to a hardware issue. Panasonic should step up to the plate and put some resources toward the solution.
I think its great that some folks have no problems with flashing lines and artifacs spanning several frames...the rest of us would like to join them and enjoy concentrating on our craft without these glitches!
How about it Panasonic?
 
For whatever reason it's hard to get anyone else to actually 'see' it. I think since I first reported this, I've had 3-4 people who have actually seen it.

I think there are two reasons for this. 1) since it pulls lines from the previous frame, it is normally unnoticeable to most people. A piece of blue sky from the AA frame looks like blue sky from the BB frame. 2) 1080 24PA is probably not the most common format to shot on.

I do know this, when I was sitting in Asia starting post on a film, I saw it. I then checked a SD DVD the producer had from a lighting test done in LA months earlier. This was from a totally different camera and from a DVD a professional house in LA produced. I could see it on the DVD. I then called a friend of mine in FL and asked him to examine his footage from his camera. He spotted it also. At this point I had to assume it is a universal HVX200 problem -- I am curious to know if it affects the HVX200A.

If any one will post 1080 24PA footage from a HVX200 that does NOT have this artifacting, I would love to see it. I have not been able to do this.
 
I see the same real estate in the pink line and J_E_Rs anomaly being affected...they are mostly likely born of the same technical shortcoming.
Is it possible that a firmware adjustment could take care of this stuff?
Now that there are plenty of examples of the problem (for those who_don't_have the problem) to peruse it would restore my faith in Panasonic to have the manufacturer take an active role in solving this problem....How about it, Jan?

Here's a zip folder:

http://www.david-jimerson.com/24pA.zip

It contains a full second's worth of an image sequence, 1080 24pA, raw MXF. I assure you that it is absolutely representative of all of the many, many hours of 1080 24pA footage I have.
