ADVC-110 - Horizontal dark lines on DV Capture

[CCEncoder]

I wonder if this is because computers don't play interlaced video too well? However when I export this to the Canopus the horizontal lines aren't visible I can just compare quality which is a little lower then the original tape with the colors being a little less resoluted and everything appearing a little more blury not as sharp... I would say is a 75% compare exactness; this on the same TV. Both input and output use s-video. Back to my question... What can I do to view this video on the computer with the interlace gone? maybe re-capturing?... maybe deinterlace it? But would I still view the horizontal lines? :roll:

Use a deinterlacing player like VLC.

Blend seems to work very good but I still see the interlacing when fast moves... Mean has lower interlace artifacts on movements but also when not :-\ Any better solution?

[CCEncoder]

I used VLC player to change the reendering mode.
ok here is the pictures:

1)Disable (normal playback)


2)Blend deinterlace mode


3)Another one I like is Mean, it shows less interlace artifact then Blend during fast moves, but since I also see the artifacts during slow moves (even though is very little) I prefer Blend instead.
By the way I couldn't take a pic of Mean... the picture appear very horizontal.

So is there a better way to play it back on my computer?

The best would be Linear or BOB -- except VLC gets the field order backwards with bottom-field-first (BFF) video like DV. Unfortunately there seems to be no way to override the field order.

Windows' built in DV decoder along with Window Media Player automatically performs a proper BFF BOB deinterlace when playing DV. If you've replaced Microsoft's Directshow DV decoder with another it may not work though.

The Blend deinterlace option simply blurs the two fields together. It looks like double exposures when there's a lot of motion.

Strange whoever program I open the video with first, the second program opens it with a lower tone... In this scenario Windows Media don't apply any interlace mode and plays the video with interlace artifacts but if I open the video with Windows Media first it applies some unknown de-interlacing method and of course the image doesn't have the low tonality. On VLC it just opens the video with no interlace method.In any case I like VLC Blend method over Windows Media interlace method yes it blurs the image a bit... Windows Media Method doesn't blur it but creates other types of artifacts... Am I right in all this...? Any better method of playing this type of videos on the PC... know that I'm using a CRT monitor.

PS. BOB or LINEAR are horrible. I tried them.

This has to do with the overlay feature of your graphics card. Only one program at a time can use overlay. So the first media player gets it, subsequent players don't. You have your overlay set up to brighten the picture, that's why the first player has a brighter picture. WMP only BOB deinterlaces DV when it has overlay.

Yes, Blend deinterlacing blurs the two fields together so the image isn't quite as clear. You also effectively decrease the video from 60 pictures per second to 30.

Bob deinterlacers split the two fields apart into two frames, leaving blank lines where the other field was. They then interpolate (linear, bicbubic, etc) to fill in those empty lines. The biggest problem with this is that sharp horizontal edges appear to bounce up and down by one scanline 60 times a second. What kind of artifacts were you seeing in WMP?

Any better method of playing this type of videos on the PC...

There is no perfect way of deinterlacing. For real-time playback under Windows BOB is about the best you can do with most players. For non-realtime deinterlacing there are smart filters that examine the two fields and sometimes the previous and next frames and try to reconstruct what's missing.

PS. BOB or LINEAR are horrible. I tried them.

That is because VLC gets the field order backwards. You get 30 back-and-forth jerks per second when there is motion -- because the fields are displayed in the wrong temporal order.

Where are the interlacing options for WM?

[jagabo]

There are no manual controls as far as I know.

You said VLC takes some fields out of order fine... so then where is that magic player that will allow bob or linear to be seem fairly as you said? sure is not WM as it looks worse then blend.

WMP looks good on my computer. Did you install some other directshow DV codec? For example, if I enable ffdshow's directshow DV decoder WMP will no longer deinterlace.

You could use ffdshow's DV decoder and enable ffdshow's deinterlacing. But then everything ffdshow decodes will be deinterlaced. It has lots of options to choose from though.

I generally only use DV as an intermediate format on the computer so I haven't bothered looking for a DV deinterlacing player.

Well is always nice to see a good playback from a vcr capture don't you think instead of waiting to have it on DVD...
I only installed Canopus DV codec I don't know if that's bad.
