Hello

I have a quesion about interlaced DV-stream and converting to WMV

I store the whole DV-tape on hard drive and then edit it with WMM. When the
film is finished i export it to WMV using the preset 'High Quality Video
(PAL)'. The problem is that the picture seems NOT de-interlaced. Is there any
reason for that?

If I export the same movie in the original DV-stream, and then compress it
with NERO H.264 encoder, the picture seems de-interlaced, as it should.

Generally de-interlacing should be done only when the final target playback
device does not support interlaced video. Interlaced video has hidden higher
resolution which becomes apparent only when you playback on such a device.
However if the target playback device is a computer monitor which does not
generally support interlaced video de-interlacing is recommended. (H.264 is
the compressed format generally for playback on computer screens/mobile
devices.)

Most profiles used by WMM are generally targeted for computer screen and
would therefore de-interlace. However some other profiles such as ones with
PAL/NTSC in their name and DV AVI are meant for final display on a TV (after
converting to MPEG2/DVD for example) and therefore keep the video interlaced
during encoding. You can also make your own profiles which allow you to
select whether or not to do de-interlacing:

Hope it helps.

Sure it helps.

Your answer is to the point. I can't test it right now, but I think you are
right. It sounds plausible.

Thank you for the reply.
