    I have a WMV file, that has interlacing line on the file. Is there a way the this can be deinterlaced. Heres the catch...I don't have the original source in which the WMV was produced. This file is in excellent quality, minus the annoying lines.

    Also I was trying to find the proper codec that for this file. So I'm posting a few info screen shots.

    Thanks in advance, for any help.

  2. It looks like vc-1 or the advanced profile. It looks like it was encoded as progressive but the source may have had interlaced content (i.e. not deinterlaced when before encoding, and not encoded as interlaced... so there is probably not much you can do). It's like encoding a progressive xvid video, but forgetting to deinterlace beforehand; so the artifacts are permanently encoded into each full frame. I say this because mediainfo should say "interlaced" if it was encoded as interlaced.

    You can try activating a deinterlacer for playback (e.g. kmplayer, vlc, smplayer), but it will likely give subpar results because of the way it was encoded. Setting VC-1 decoding to "WMV9" as the decoder in ffdshow for directshow players (not set to "libavcodec") is supposed to be able to handle truly interlaced VC-1 better for directshow players (e.g. MPC, WMP).

    You could also try playing it through an .avs script, so you have more selection of deinterlacers - but again if my guess is correct the results will be subpar

    You could post a small sample at a free hosting site (e.g. mediafire.com, megaupload.com), and maybe someone will have better ideas when they examine it more closely. You should be able to cut a piece off with asfbin

  3. With a frame height of 540 lines the video was probably resized and the two fields are no longer separate enough to deinterlace.

  4. Here is an example of a (proper) WVC1 interlaced video. Mediainfo identifies it as interlaced. You can see the artifacts when you open it in an .avs script e.g. DirectShowSource() . You can improve the playback on a PC software player by activating the deinterlacer in kmplayer, for example, or WMP11 which automatically applies deinterlacing. I doubt this is what you have.

  5. You could always use Windows Media Encoder to re-encode the file as a new, deinterlaced WMV.
