HVR-HD1000P for video shoot in India/ major problem with video footages

Hello Everyone,

Just came back from a video shoot in India. We used the HVR-HD1000P in HDV 1080I format.

Camera functionality not that user friendly. always need to go to the manual ring to change focus, zoom, etc..etc.. very cumbersome : (

BTW I am having major problems with some of my video footages which I only realised when I was back in Singapore. Some of my video footages on the HDV tapes while capturing had subtle running streak moving from top to bottom continuosly, they appeared at random in the HDV tapes ( I don't know whether my camera's faulty or cameraman at fault ). Check the same HDV tapes on my HDV decks and the problem persisted. I used both firewire and HDMI for capture and still the same. Concluded the problem had arised during the video shooting and while recording to tape. What did we do wrong? and Is there a solution to remedy the problem?

Any chance you could post a still image? Sounds like data dropout/corruption. Did you clean the tape heads at all while shooting? If not, that's probably the problem.

India and Singapore seem to be both PAL (I assume 50hz for both or some derivative).

I've shot a lot of 50hz PAL in NTSC 60hz surrounding area, and lighting it isn't a rolling top->bottom effect so much as an steady, intermittent flicking along frames. Maybe with a really weird shutter speed.. not sure.

If the camera has a rolling shutter then it would most likely have a rolling top to bottom effect.

Hi Damien....................

Well, that sure looks like good 'ol flourescent roll to me.

The interaction of the 100 Hz flourescent strike rate with the chosen shutter speed would appear to give the problem I'm seeing on my screen.

(Flouro's strike twice per mains cycle, 50 Hz mains, 100 Hz strikes on the lights).

If the shutter speed is faster that about 1/50 (or even less) then you are bound to get this effect.

As far as I know, absolutely bugger all you can do to fix it (afterwards) I'm afraid.

Don't shoot faster than 1/50, preferably 1/25, so you get two full strikes for every frame (or even one full strike for every field if using I mode).

PS. It came up as only 1.6 meg on my download.

I can't get the video. What is the period of one full roll?

The mains frequency might not be exactly 50Hz and I would guess this might be specifically true in rural or remote areas supplied by smaller/older power stations. If the mains frequency drops to 49.5Hz you get 2 second beat pattern with PAL framerate that might look like a rolling band.

Maybe I am talking tosh!..
