Hardware

2003 Targa Laptop with 3GB hard disk and firewire port

Software

Knoppix 5.1
Kino and
FFMPEG and FFMPEGTHEORA
(Kino and FFMPEG and FFMPEGTHEORA need to be installed via Synaptic package manager under System on the KDE (Knoppix) default menu)

Demonstration of Kino Features

Trap for new players projecting Video from a Laptop - while the Video was visible in Kino on the Laptop, the Video didn't appear on the screen via the projector, plugged into the external monitor port of the Laptop.

Fortunately there were knowledgable people in the room, who diagnosed the problem and solved the problem - change the Display in Kino (via EDIT/PREFERENCES) to XVideo to GDK). A similar problem occurred with MPLAYER.

Capture uncompressed Digital Video from Camcorder over firewire
5.08seconds of Video 17.8MB file - 60 minute DV Tape makes sense
(DV uncompressed video files are large)
Note: Kino needs to be run as root - to enable camera control via firewire port
Save Still Frame
Edit - Cut and splice
FX (Special Effects) - Fade, Barndoor, Mirror transition between clips, Titler
There is a special effect preview - however, once Rendered a special effect cannot be undone
Bearing in mind the size of the DV files - you can choose to create new files or overwrite existing files when you render the special effects
Export & Save for further editing
- uncompressed DV back to tape/Camera
- Audio to WAV format
- MPEG2 - DVD/Digital TV
- with FFMPEG and FFMPEGTHEORA installed (via Synaptic Package manger) - export OGG, H.264 etc
  Two versions (qualities) of the Clip edited during the meeting were exported
  a)OGG THEORA - High Quality 640x480 (File Size: 3.9MB file)
  b)OGG THEORA - Low Quality (160x128,128Kbps) kino-demo-slug-31-Aug-07.ogg (File Size: 155.6KB
- Save as SMIL (and uncompressed DV files) for future editing
  - Sample DV file size: 001.kinofx.dv (length 00:00:00.880) is 3.239MB
  - Sample SMIL File:
