Lightspeed Live Capture User Guide
In most cases the resulting output file will be playable and can be used for editing. The
default duration has been exceeded."
3. If scenario #1 or #2 occur with a Workflow in the 'Open' mode, and the action
immediately following the capture origin action is an 'Open' Copy action, the file
copied by the 'Open' Copy action will retain the original
Default Duration . The
copied media file will show a duration equal to the Workflow's Default Duration and
will be playable and editable. Captured files stopped prior to the Default Duration
(scenario #1) will contain no active media data from the point where the capture
session was stopped through the end of the file. Some media players or edit
applications may display errors or faults when trying to access the timeline
locations with no active media data.
Header Compression . Compresses QuickTime header information to improve
playback responsiveness when downloading the file.
Color Space . Set the QuickTime file color space. Options include:
- Do not specify
- ITU-R Recommendation BT.601
- XYZ with SMPTE 428-1 (DCDM) Transfer Characteristics
- ITU-R Recommendation BT.601 with SMPTE-C Color Primaries (NTSC)
- ITU-R Recommendation BT.601 with SMPTE-C Color Primaries (PAL)
- ITU-R Recommendation BT.2020
- ITU-R Recommendation BT.709
- RGB with BT.709 Color Primaries
Conform Aperture . Check to enable, then choose one of these options:
- Disabled
- Classic - Displays the image without applying either the pixel aspect ratio or the clean
aperture. The image is displayed using the track header dimensions, meaning the
decompressed picture is scaled into the track header dimensions if the encoded
dimensions are different.
- Clean Aperture - Both the clean aperture and the pixel aspect ratio are applied. The
dimensions of the track become equal to the clean dimensions which are equal to the
display dimensions (with conformed contents).
- Production Aperture - Applies the pixel aspect ratio but not the clean aperture. The
image is presented in the correct aspect ratio, but the extra pixels outside of the image
that exist in the source material will be presented. The track dimensions are equal to
the result of applying the pixel aspect ratio.
- Encoded Pixels - The encoded pixels are displayed intact in this mode. Under this mode
the track dimensions are equal to the encoded dimensions. No scaling or
transformation takes place.
