Setting the SD MPEG recorder aspect ratio
When you record standard definition material with an MPEG recorder, you can specify
the aspect ratio to be used when that material is played out on an HD output. If you select
an aspect ratio of 16:9, this setting overrides the default up-conversion aspect ratio
setting for the playout channel.
The aspect ratio attribute is saved as part of the MPEG video media file. If the clip is
transferred to another machine or used as part of a complex movie, the attribute remains
in effect.
Once the clip has been recorded, you can use Media Manager to change the clip’s aspect
ratio when it is up-converted for playout on an HD output.
This attribute applies to all clips recorded on a channel with this setting.
To set the aspect ratio when recording SD MPEG material:
1. Double-click the video icon ( ) to expand the configuration tree.
2. Choose a video track in the configuration tree, such as
Track 1
.
3. Click the Aspect Ratio button to see the aspect ratio choices.
4. Select the desired aspect ratio, then click
Finish
