Analog -> IEEE 1394

IIRC, my handheld camcorder provides the ability to connect an analog input, and pass the
captured video through to the IEEE 1394 port.  I used dvgrab, kino, and transcode a number of
years ago to massage some vacation video, and was generally pleased with the results.

IEEE 1394 is nice, but...

It was quite a struggle to get video out of IEEE 1394 camera under Linux too. Sure, tools come with your distribution - but they just don't work! Under Mac everything just works and under Windows you need to download executable and tun it. No need to search for strange stuff on livna, no need to compare pluses and minuses of different modes: just plug camera in, hit "capture" and get the stupid .avi file!

Editing under Linux is not so bad - though I'm yet to see any editor where I can look at 4-5 synchronized captures from few cameras and choose fragments - but that functionality is probably considered too advanced for amateurs (even if it existed 50 years ago) so I'll settle for what is available...

Other external solutions for analogue->digital video

Sigh, here in Europe the analog input is usually missing from consumer grade camcorders, even when present in the same model sold outside Europe, because of a certain stupid protectionistic tarif.

But I have seen some external analogue-digital video converter boxes that attach to USB or Firewire. Does anyone have experience using such devices with Linux?

One very easy solution is to use a recording DVD deck. These are quite affordable these days, and Linux video software has no problem in reading the resulting discs. They do perform a lossy MPEG2 compression, but when you use the maximum quality setting of the deck, it is unlikely to matter, since that quality is probably still better than what your analogue camcorder generates (unless you have serious professional equipment). I have used this method for digitizing my SVHS-C tapes.

The acedvio card from canopus works fine over firewire with dvgrab. (A$500, though - they used
to make cheaper products.) The "--format dv2" option is a good choice. Grabbed video+audio in
DV format is excellent quality, but you need to allow space for about 12 Gbyes/hour captured.
Kino works ok to edit and convert to lower bitrate mpeg2 format for DVD.

I'll be interested to know how long the grumpy editor takes to edit his captured footage. I
believe the standard conversion factor is 1 hour of editing per minute of finished product.

Another possibility is a "media bridge".  Essentially that digital camcorder minus the optics.
Video (composite or svideo) and stereo audio come in one side, dv output over firewire on the
other.  The one I have at home seems to branded as "Dazzle", but I seem to remember Sony
making them as well.

Of course, that's a new piece of hardware, and our Grumpy Editor already has the Hauppauge
card...

Sony's DV decks maybe what you are thinking of. But they generally cost more than cameras :-)
