# Configuring Software For Clip Input and Output Using a VTR

Software configuration in preparation for clip input and output session involves editing the software initialisation configuration file. The procedures for enabling devices in the software initialization configuration file are described in the “Configuration Files” and “Configuration Keywords” chapters of the Autodesk Visual Effects and Finishing Configuration File Reference Guide.

When you are preparing for a clip input and output session, consult the software initialization configuration file to confirm the following keyword sections are uncommented and properly configured:

- VIDEO KEYWORD

  You do not need to specify the default video I/O timing. The initial timing corresponds to the default resolution and frame rate of the project that you select on start-up. If you select a film or custom resolution for your project on start-up, video I/O timing corresponds to the resolution that was selected as the preferred resolution when the application was installed.

- VTR KEYWORD

  You must assign a specific VTR timing, such as NTSC, PAL, or 1920x1080_5994i. Multi-format video input and output capability of your system allows you to modify the VTR timing, without exiting the project, to any timing supported by your system's video board.

  If you plan to perform input and output operations using a live video signal from a broadcast feed or from a device that does not support remote control functionality using RS-422 interface, such as a VCR or camcorder, uncomment the corresponding Live video keyword at the bottom of the SD DECKS section.

  NoteWhen working in HD projects and capturing material from a Varicam (variable frame rate 720p material), ensure that the following VTR tokens are enabled: VTR DVCProHD 720 59p, SERIAL1, 1280x720_5994P and VTR DVCProHD 720 60p, SERIAL1, 1280x720_60p.
