If I'm thinking of buying, the how you do X part of the reference
manual is usually the fastest and most reliable indicator of the
exactly what it is and the degree of reality of an advertized feature.

And no, I haven't read the manual on the netbook cover to cover yet,

Of course the flip side is I _strongly_ believe we should..

 * write our software so simply and clearly that nobody needs to read
   the manual!

 * write our manuals so that they are a pleasure to read, so they read
   them anyway.

 * where possible use webish interfaces so the software and (portions
   of the) manual is the same thing. (You should _never_ have to
   lookup up in the manual what a widget does, the context sensitive
   help should tell you all and more.)

 * write our code so no one needs to read the comments.

 * write our comments in a manner that makes our spirit and intention
   clear.

 * keep our spirits and intentions so simple and direct that our work
   may be reused for purposes we never dreamed of.

...leastways that's where I'm aiming.

Manuals are more reassuring than useful, it's kind of like a technical
comfort blanket...most companies never actually expect anyone to read
them hence why most lack basic proof reading for clarity and seem to
have been translated from the japanes to English via cyrillic and
klingon.

On the other hand, the camera plays with Linux very nicely over USB...

I'll check the video on my Canon S2IS.


What is your camera Stephen?

My camera is a Canon S1IS. I have made several short videos with it. 
Just tested 2. VLC reports the video codec as MJPG, frame rate 30.000300 
and the audio at 22050 hz, 16 bits/ sample and bitrate 325 kb/s


mplayer  vlc play them quite nicely, xine is a dead loss.

For a friemd I made 3 movies into a dvd (pal) using kino. It works ok




[1] Does anyone else read instruction manuals cover to cover? For pleasure?


For my camera I browse from time to time, it still intrigues me with its 
capabilities.

I have a nearly five year old camera - I seem to recall it being called
a 'Prosumer' or something. It is still pretty good by today's standards
if don't think about the cost.

I still look through the manual occasionally and find new things it can
do - particularly as the memory cards now are not expensive.

But as a former black and white enthusiast, I wind up going back to
manual exposure and manual focus. It's much more fun to mess up photos
*my* way :-)

Canon A720IS -- the cheaper range.

Video is MJPEG 640x480 at 30 fps. Audio is 1 channel (mono) 8-bit PCM at 
11024 Hz with a bitrate of (obviously) 88 kbps. Its microphone is such 
that anything else would be wasted bits.


After copying videos to the PC, I use ffmpeg to convert them to H.264 
video with AAC audio (no free codecs for me :(. The converted files take 
1/3 of the disk space on average, with the best-compressed using only 2% 
of the original, and the worst about 70%. The best compressed video was 
a long sequence of a person doing 3D stunts with a radio control model 
aeroplane -- the camera was on a tripod, he was standing still, the sky 
was a uniform overcast grey, and the only moving thing was the tiny 
plane moving around him.


I have also used Kino to create a movie and found it stable and easy to 
use. I just hate the idea of converting everything to DV format first.


OpenMovieEditor is my recent favourite, but the version in the Ubuntu 
repositories does know about enough video and audio formats, so I had to 
compile my own. Unfortunately, it got broken in the cross-grade from 
Hardy to Intrepid and I have not recompiled it yet.
