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
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.
