What works and what doesn't work of the video software in the video room. (Kino and Cinelerra)
Both Kino and Cinelerra handle DV in Quicktime or AVI container.
Kino can also load and produce raw DV.
Kino has a easy one-window GUI, and is rather quick to get
started with. For DV it is a proven, simple editor.
Cinelerra can import more formats. MPEG1 and MPEG2 are quite
OK if you remember to not open the MPEG directly. For MPEG1/2
Cinelerra wants a Table of Contents file, which is generated
with the command line tool mpeg3toc. Then you open the ToC
file instead.
On our fast video workstations (3.4 GHz Xeons with lots of
RAM and SCSI RAID) Cinelerra handles HDV (high definition
MPEG2, resolution 1440x1080, stretched to 16:9) well.
I have brought an HDV camera.
Caveat: Cinelerra does not support well all the formats that
it is willing to open (which are not all that many).
Workaround: Not much, except testing a lot...
Caveat: The installed version of Kino often gets totally un-
responsive or very sluggish.
Workaround: Patience, or use Cinelerra.
Caveat: The installed version of Cinelerra outputs DV AVI files
that neither Vlc, Xine or Kino understands (they don't understand
the fourcc¹ "dvc"). Mplayer plays it fine, though.
Workaround: Let Cinelerra output Quicktime DV (.mov) instead.
Caveat: The installed version of Cinelerra has broken rendering
for most formats except DV. Of the comressed formats, only
Ogg (Theora/Vorbis) seems to work.
Workaround: If you want Cinelerra to output e.g. XVID, use the
YUV4MPEG pipe output. It has the annoying limitation that it
is video only; no sound. The sound has to be rendered in a
second pass, and then multiplexed with the video. ffmpeg can
do the muxing.
