I've used kino for grabbing
DV ist just grabbing, no transcoding as I had to do with my analog
videocam in the past.

On your quality issue, I assume you are using dvgrab. Are you
capturing to mpeg or using the qt option which yeilds much better
results. (bigger files). Trying to do any pre processing on mpeg
generally imho is awaste of time. It just falls apart.
dvgrab -f qt

Hello,
the simple answer is: always deinterlace your source footage,
best even
before you add it into the project. As said, that is the
simple answer;
if your intention is to view the final result mostly on a
computer monitor,
your're best off deinterlacing right away.
This is not the full story; sometimes you might have
compelling reasons
to want interlaced footage as a target (output) format of your
work.
But I'd say, going this route is always more involved and
something
for the more experienced users.
Note: Cinelerra has basically no support for handling
interlaced footage.
If someone knows exactly what to do, it is possible to handle
interlaced
footage in spite of this shortcoming. But, as said, best stay
away from
that topic unless you want to engage in quite some additional
difficulties.
Well -- for sake of completeness I should add, that you can
squeeze out
some additional quality especially for the case of slow motion
done with
ReframeRT *if* you understand to exploit the additional
temporal information
contained in interlaced footage.
Hope this gives you an general orientation on the topic,
please feel free to ask more detailed questions if in need of
additional
advice!
Cheers,
Hermann V.

hey,
thanks for the advice. The problem is, overall, that only one of
my test deinterlacers can do good enduser deinterlacing. That is
vlc's "X".
Some minutes ago I did deinterlacing with avidemux with a
rendersource from cinelerra.
All avidemux deinterlacing methods I've tested so far were really
bad, jerky and so on :(
It would be great to use the 50 frame advantage of interlaced
source instead of the progressive 25 fps which results in stuttering.
During my learning process I've alwas tried to raise the qualitiy
of the source material (camera handling, in the past A/D, now easy
with DV, no transcoding/damaging of the original source material).
Therefore I am surprised of your suggestion.
And no, I doubt I don't understand the relationschip between
interlacing and concrete advantages in ReframeRT yet
Regards, Chris
