Pixelation while panning?????Sony TRV17

[tchambers]

I am getting serious about editing my DV efforts. I have noticed that after capturing my dv uncompressed, I notice pixelation around my subjects while panning a scene or even zooming too quickly. After editing and turning my final into mpeg, the problem is still there. Is this something I am doing at capture, or is this a product of an older, one chip, camcorder? I am looking at the Panasonic ###400, not sure of the exact model, but seems to get great reviews and is a 3 chip unit. Would this cure my problem?????

Pixelation as in Macro Blocks ? DV requires some pre-processing ahead of the Mpeg2 encode in order for one to get truly superior looking video. There are a number of ways of avoiding it, or fixing(reducing) the problem . Do a search for DV and Macroblocks or Macro Blocks.

It sounds like you are talking about interlace comb lines. If so, ignore them, they won't show up on TV if you convert to DVD MPEG correctly.

I am not sure what you call it. The edges of my subject gets blurry or blocky. I use Video Studio 9.4.3. Is that sufficient for conversion to dvd??

Open your video with VirtualDubMod, seek to a good sample frame, use Video -> Snapshot Srouce Frame to save it, and post it (or a crop) here. Do not resize because that will "hide" the details.

junkmalle, If you don't mind, I have some guests in for a couple of days and will not be able to send you the edit. I would like to address that over the weekend if you don't mind. Thanks

tchambers, no problem. If I miss your post send me a reminder pm.

Make no judgements from the RGB progressive preview screen on the computer. You are probably seeing the normal result of displaying a interlace source on a computer display*.

Use VS9 to burn a test DVD with the clips of concern. Use VS9's default DVD settings initially. Burn the DVD and look at the result playing from DVD player to the TV. Compare the result with the original. It will probably look fine. If not ask again.

*interlace video divides the picture into fields. each field contains the odd or even scan lines. The fields are captured sequentially every 1/60 sec.
A TV displays fields sequentially and everything looks fine. A computer shows two fields at a time every 1/30 sec. If there is motion during that 1/60 sec, such as a pan, the computer image splits due to the relative motion every other line. An extreme case is a pan where most motion is in the horizontal.

Bottom line, there is no problem with the video. The problem is with the way a computer displays interlace video.
