Well, the funny thing is, that's just the physical support. MiniDV can
carry either standard-def DV, or high-def MPEG2.
Is it an HD camera or standard-def?
I installed cinelerra
and will try to install Kino now.
If it's standard-def, you can quickly capture video from the camera with
a command-line tool, if you wish. It's called dvgrab and it's part of
the Kino project, but it's usually a separate RPM - CentOS has it in the
Base repo.
This is what I use with dvgrab 3.0:
dvgrab --autosplit --size 0 --format dv2 --opendml --noavc --nostop \
--showstatus --timestamp --frames 0 --buffers 200 ${basename}-
Rewind the tape, connect the camera to the PC, start dvgrab, then push
the Play button on the camera. Wait until the whole tape is dumped and
the camera stops. Kill dvgrab.
With the above parameters, dvgrab will start a new file whenever there's
a scene change on the tape, which is nice. Those files can be viewed
with lots of different players (xine, vlc, mplayer...) and edited with
Kino to cut off undesirable portions and stuff like that. With Kino, DV
editing is lossless.
There are many ways to convert DV to all kinds of other formats. With
Linux-based tools, one way to do conversion to DVD is this:
http://florin.myip.org/soft/conv-dvd/
I attached to this message another script which pretty much does the
same thing, except it requires Windows-based tools running under WINE
(AviSynth, HC Encoder, and associated software), but the image quality
of the DVD is much better, since HCenc is a very good MPEG2 encoder.
Under Linux, without WINE, for DVD you can encode to MPEG2 with either
mpeg2enc (so-so image quality, so-so speed, good standards compliance)
or with ffmpeg (fast, poor image quality, produces MPEG2 that violates
the DVD standard and may crash some standalone DVD players).
mencoder is similar to ffmpeg since they use the same underlying code.
HD is a very different story.
dvgrab can still be used for capture with MiniDV/MPEG2 cameras.
I've heard that Cinelerra may be able to edit HD MPEG2.
I doubt there's anything on Linux that can reliably parse and edit
AVCHD, because libavcodec (essentially the only AVC decoder on Linux,
and the only open source AVCHD decoder on Windows) has pretty big
problems parsing interlaced high-def AVC (but if your camera is MiniDV,
it's definitely not AVCHD).
I'm not sure how to do Blu-Ray authoring on Linux (or at least the poor
man's Blu-Ray-file-structure-burned-on-DVD, a.k.a. AVCHD disks) other
than running tsMuxer under WINE (or try the Linux version, if you can
figure out how to use it text-mode).
For BD or AVCHD authoring, you may have to transcode MPEG2 to AVCHD
(unless you can produce on Linux a BD structure with the video track in
MPEG2 format). Hopefully x264 works for you, but you may have to
interface it with AviSynth - under WINE, of course. :-)
It's not a pretty HD situation on Linux. Windows is much better.
