That's the problem - "dv1". You need either dv2 or better yet
Quicktime or (IMO) even better 'raw' (but for 'raw' you'd want smil2yuv
and smil2wav).
Actually, it seems I made that up. I did capture with dv2.
So why's lav2wav busting my chops :)
Type 1 AVI files are not (well) supported.
Might be possible to use Kino to read the type 1 and write a type 2
AVI file.
With the recent (this weekend) changes to lav2yuv (to support "-C 411")
the data can be processed in 4:1:1 right up to the point where
MPEG-2 encoding takes place.
OK. I'll get cvs.
If I get this correctly, DV ( NTSC? ) records video 4:1:1.
dvd mjepg2 is 4:2:0. So my present command "lav2yuv -C 422 |
yuvdenoise | y4mscaler -O preset=dvd | mpeg2enc ...." -
which is the result of an info mesage from lav2yuv -
upsamples the dv stream - a Bad Idea.
Where does it go to 4:2:0? mpeg2enc? Or does y4mscaler
take care of it?
