# Things to Remember

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.
- Smoke 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, Smoke 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.
