horisontal lines

[gradel]

Hi,
as I´m relatively new to digitalize video, maybe this is sort of a newbie question. But I´ve purchased a Gainward Geforce 2mx vivo card partly because its ability to get my home movies into the computer (i´ve got a Sony trv330 Pal-digital 8) and see what resault/quality I can get. One problem I´ve ran into is that when I digitalize in high resolutions the movie get horisontal lines mainly when the camera is moving around. Does anyone has a clou why?

Could be your system, Horizontal lines are a symptom of the processor being over-worked, try shutting down some other processes such as antivirus software or anything else you are not using...

WTF are you on about mh2360 !!

I would say without a doubt that these are interlace artifacts. Try looking for interlace on the board and see all the results come up. If I remember correctly some of them have screen shots showing the effect, so you will be able to compare between what you are seeing at home and what people are describing.

If you are playing back on a TV using a DVD player then I would encode with interlacing turned on (it doesn't look funny on the TV) or if you want to playback on the PC then you can use one of the many filters available.

Those are just normal interlace artifacts. You won't see then on your stand-alone DVD player. Rather then de-interlace, select "Inverse 3:2 pulldown for the encode mode. That willmake it look better on both your computer and your DVD player.

Barnabas, No it wont.

gradel has stated that his source is PAL interlace, not FILM. Home movies look really bad deinterlaced.

The only framesize you can run at 23.976fps is NTSC (720x480). PAL progressive is still 25fps.

@ dattrax

Not all horizontal lines are interlace issues....

OK, point taken, but I would still bet in this case it is.

Reading gradel's post again, I see that he is talking about horizontal lines, not vertical lines.

Vertical lines are almost always interlace artifacts, but horizontal lines tend to be some sort of ac power interference. I get the same thing here on captures unless I unplug a brick power supply or two.

I once had a similar problem, I could capture fine at normal resolutions (352 x 288 or whatever), it was only when I captured at around say, 640 x 480, i got horizontal lines. I never really got to the bottom of it, I assumed it was my hardware that was simply not up to the job and gave up trying...

Go and get a RF stopper. It is a magnet in Conical shape
All those horizontal line problems gonna disappear (if that is the case)
BUT: Cables after a while are damaged by RF Stoppers, so use them wise!

i have the same « kind of lines » duet hardware limitations
now i normally capture (old Asus 6600/deluxe) in 352x288 or 352x576 (pal) and it works
above that they are the lines again.

I think this may of been my problem when I encoded a "Jimmy Neutron Boy Genius" movie withe TMPGEnc. I kept it non-interlaced (progressive) NTSC (I didn't select "NTSC Film"). Should I have selected NTSC film?

I'll try to re-encode as you say Dattrax (interlaced turned on) and see if that helps the horizontal lines I see in motion scenes on my stand alone DVD player.
