When working with multi-format
            video material in the same session, consider the following:
         
         
            - You set the default timing for your project
               when you assign it the resolution and frame rate at the time of
               creation.
            
- Even if a project has a specific timing
               (resolution and frame rate), it can contain clips of various timing.
            
- You can input clips from any device supported
               by your system's video board, but clips are captured at their native
               device-based resolution and format.
            
- You can output clips to any device supported
               by your workstation, but clips selected for output must be of the
               resolution and format that correspond to the video timing of the
               device.
            
- You can change the video timing of your
               VTR device without exiting your session, but to output to a VTR
               of this timing, you must also change the corresponding hardware
               connections.
            
- The preview timing in the Preferences
               menu is linked to the Clip Input menu. In other words, when you
               change preview timing in the Preferences menu, the change is reflected
               in the Clip Input menu.
            
- Backdraft Conform checks if your video sync
               matches the timing of the material you are working on when you load
               a project on start-up, change projects in the Preferences menu,
               change preview timing in the Preferences menu, or select an output
               clip.
            
- When a project is loaded or timing is
               changed, Backdraft Conform selects an appropriate VTR for you, if necessary.
               The VTR devices available depend on the VTR keyword lines uncommented
               in the software initialisation configuration file.
