SONY TRV480 fast movement problem

[nitestalker49]

I cant figure out why when i record i have lines thru anything or anyone that is moving fast. For example, I recorded a campfire we had a few weeks back. and i have tried all kinds of filters and such with vdub with no luck. i have been messing around with this stuff for a while but never been able to get rid of these lines or whatever they are. Other wise i feel that i am pretty knowledgeable about it all.

I am running HI8 tapes @ LP to get more time. i record alot of fishing trips so it really works out to put it on the tripod and not worry about it.

here is a demo video in Xvid format which is approx. 20 MB of the camp fire.

Don't know if this is the cause of the problem but I've heard that recording at LP be it Digital8 or miniDV is a big no no as it is harder to read the tape and this can cause issues which very well might be the cause of your problems.

I've never recorded LP speed with Digital8 or miniDV but I wouldn't be surprised if that is the problem here.

I'm trying to download the clip but man o' man is it downloading SLOW ... it's saying 36+ minutes and I have a fast cable modem connection.

ok i switched the camera settings to SP and it really made no difference. Here is two captured jpegs from the video file using my BSPlayer:





i also been messing with the setting aquanting myself with them better and i have seemed to rise the quality of my recordings but i still get those lines no matter what i do.

i have been taking the stills and blurred them and that seems to help but as for the video it just lessons the quality big time. black and white seems to work alot better too , leaving me without the lines.

any suggestions anyone?[/img]

Just looks like interlacing to me

Nothing wrong with the camcorder. Plug into a TV and it looks fine? Sure it does.

Nothing wrong with Vdub because it is maintaining interlace as it should.

What you are seeing is interlaced video on a progressive video display. It is supposed to look that way. The more motion the more the fields will split. They are offset in time by 1/30 sec.

What are your goals for this video? If it is to display the finished product on a normal TV set you don't want to change anything, just edit it and encode to DVD MPeg2 as interlaced video.

If you want to watch it on a computer display, use a deinterlacing player like PowerDVD or WinDVD. A version is usually packed with your computer or DVD drive.

ok, thats what I kinda thought but.... why when i use vdub to deinterlace it, there is no change?

Most of my recordings lately have been in LP mode of my Sony TRV350.
I've not noticed any difference in quality.

The performances however, those could be improved with talent. :P

There are various ways to deinterlace video but each one of them* is destructive to the video. Best to do it for display only using a player intended for progressive displays. If your goal is extreme compression and progressive only display, then you you will choose your compression strategy which may well include deinterlacing the actual video. Many goals, many solutions.
