Setting Up Channels for Playback

This topic contains information on how to set up channels for playback.

To set up channels for playback:

1. For each channel 1-4, select the option for each of these fields as applicable for your site:

2. For each channel 1-4, in the On End of Clip field, select the behavior that you want this

channel to exhibit when playback stops (Show Last Frame, Show Black, etc.).

3. For each channel 1-4, select the Output Ancillary Data check box to allow the ancillary data

to be played out from the AirSpeed 5000 server.

4. For each channel 1-4, select the VITC playback line number that you want to output VITC

timecode to.

For NTSC, VITC playback is supported on Lines 12-19.

For PAL, VITC playback is supported on Lines 9-22.

5. The Output Timecode Based on Clip Time field enables you to determine which time source

is used to receive output for time information (ATC, or VITC) when a clip is played. The

behavior is as follows:

t When selected, the AirSpeed 5000 forces the output timecode to follow along from the

base time associated with the clip.

t When not selected, the output timecode is based on the data in the ancillary track.

6. In the Output Format Behavior field, select the output format behavior for the channel.

Options and descriptions are as follows:

t 1080i/NTSC/720p - If you select one of these options (1080i, NTSC, or 720p),

AirSpeed 5000 will play all clips at the corresponding output format.

t Switch on Fly - If you select this option, the software ignores what the video standard is

set to for a given channel, and the video standard for the channel automatically switches

to that of the clip that is currently playing in the channel.

Playing clips back-to-back is not supported with the Switch on Fly option. You must unload the

clip before cueing the next one.
