A bunch of us here have been working with HDV for years. I personally haven't shot DV format since February '06.

Go ahead, ask away. People are pretty friendly here.

Nothing personal guys but I'm located in Hawaii and we as a people here and I mean professional video and audio companies and individuals just don't know enoughabout HDV including me. Thats why I have you good guys to talk too.

The situations that I'm going through is the basics on how to capture, edit and author it to Blue Ray. Besides reading books and watching the training DVDs to learn from I still can't figure out why the HDV captured footage looks jiggery. It's not smooth in motion. Can I fix those clips.

Thanks.

the HDV I've captured looks smooth. is it interlace-jitter? If so you could be rendering it to the wrong field order.

It could also be rolling shutter. What camera(s) are you using?

Hi Jrazz. I'm using the Sony HVR-Z1U camera and it's capturing at a native 1440-1080 interlaced. I always shoot with manual settings so if the LCD screen lokks jittery I change the settings. What I shoot is not jittery it's the capture part that I need to study on. When it comes to the field order my render settings is MPEG 2 format and I want to burn it to Blu Ray so the template is Blue Ray 1440-1080 60i. Is this the right settings to render an HDV 3 hour long wedding?.

Hows it going The Happyfriar. It could be an interlace issue. I'm rendering as a MPEG 2 format using a Blue Ray 1440-1080 60i template. Is it in my shooting or is the jitters in the capture because I do not see any jitters while shooting with the Sony Z-1 with all manual settings with the shutter at 60. The jitters really show when I pan from left to right ONLY. If I walk in or out or zoom in or out or tilt up or down there is no jitters at all. My software capture settings is at default HDV 108060i but my camera is recording at 1440-1080 60i. Should the record and capture settings be the same or it does not matter?.

Thanks.

the only resolutions for 1080 are 1440x1080 & 1920x1080. i use vegas to capture and it's always captured my 1440x1080i at that resolution (upper field first).

where are you seeing the jitters? On the BD playback, in the vegas preview, etc. What happens if you leave the shutter to auto?

how fast is the pan left/right? if it's to fast it will almost always jitter a little bit no matter what.

Just curious here, is panning right to left OK?

You probably would not see anything wrong when shooting for the simple reason that motion looks different on a tiny LCD viewfinder compared to a large monitor. Capturing will make no difference, it's pretty much just a data transfer. If in doubt hook the camera up to a largesih HDTV and play the tape back.
Be aware that what you see in the Vegas preview monitor is not what you get mostly. The refresh of PC screens can do screwy things with motion etc although I suspect if you set your PCs screen to the same refresh as the field rate might help get more accurate preview.

In general as others have said you must watch your panning rates. Things change in HD all else being equal. More resolution and bigger screens change things in subtle ways inc motion perception. Also too much Detail or Sharpening in the camera can cause motion problems.

I've noticed on broadcast HD channels (Comcast) I often see 'jitters' and slight pixelation on fast pans and moving objects. So its the nature of the format that you want to avoid those fast behaviors as much as possible to avoid having it show up in your finished project.
On the other hand, I must admit I'm a bit less critical of my own footage when I see it happening even with the 'professional' footage.....

Well, the style that I shoot is very cinematic and smooth in "MOTION" mostly from left to right and it's the left to right clips that is jittery the rest is fine. What is this upper and lower fields. If I change the fields will the jitters go away?.

When I first got my Z1 I set it to full auto with optical stabilization on and shot some winter footage of siding on the house (horizontal lines) and with great spasdic endeavor whipped the camera up-down-rotate-sideways-back and forth just like a new camera dork. To my astonishment the result had no pixelation, no horizontal squigglys, no vertical squigglys, no jitters, and it didn't give me a headache. Captured through the ADVC 300 and Cineform and everything still ok. Well there was only one thing that changed and that was the focus but it wasn't very much. And also if I pan a still photo with the Z1 it is rock solid and I don't get the still picture squiggles that you get when panning in Vegas on some stills.
