I got some DV raw material [Analog Camera -- Canopus Box -- Firewire]
with kino (I know it can be done also with dvgrab).
I did run that DV raw material with MPlayer in my computer:
- Audio is great aceptable.
- Video quality is not perfect but it is acceptable.
A decent analog-dv box, which I think Canopus is, should give you very
good quality. I am not sure I understand what is not perfect about your
video. Is it interlacing artifacts that troubles you? Video for TV
Well, maybe is interlacing but not only that, I was refering also to
what appears to be not clear/ grain video.
you may see combing effects at fast motion scenes. (see
http://www.lukesvideo.com/interlacing.html) Try playing with mplayer's
deinterlacing option (-npp lb ?) for a smoother looking display.
Very good link to understand interlacing, thanks.
If your final mpeg or divx movie is meant for viewing on a TV monitor you
need not worry about the interlacing artifacts, but if you are more
concerned about smoother display on a computer monitor you can deinterlace
the video using yuvdenoise -F before transcoding. Deinterlacing is a
lossy process so do it only if you really need progressive video. Most
software players can do some primitive deinterlacing on the fly.
If you are talking of quality issues other than interlacing artifacts,
try to describe what you see in more detail -- someone on the list may be
able to help you.
I am doing more testings with more options. The video appearance of
my first few works was not good (grained ??? maybe that is not the
appropriate English word; not good resolution ?? as seen at the
screen).
I am just starting with this video conversion and I will probably need
some more testing. Maybe higher Bitrate, even it takes more CDRs would
be a solution.
Best regards and thanks again for all that valuable information.
