| Profile
|
A profile is a collection of data that describes the
configuration of an WMV file. At a minimum, a profile must contain
configuration settings for a single stream. The stream information
in a profile contains the bit rate, buffer window, and media
properties for the stream. The stream information for audio and
video describes exactly how the media is configured in the file,
including which codec (if any) will be used to compress the
data.
ScreenVirtuoso has a set of standard profiles. Simply select a
profile from the drop down list.
You can also import your own profile by using '+'
button. To delete a profile use '-' button.
Note, if you import a new profile, it should correspond to a video
file. For example, both video file and profile should have an equal
number of video/audio streams. Otherwise, errors are possible. |

| Frame Indexing
|
There are three different types of indexes: temporal indexes,
frame-based indexes, and SMPTE time code indexes.
Temporal indexes are the most common type. They simply equate video
samples with the corresponding presentation times.
A frame-based index equates video samples with video frame numbers
and presentation times. Frame numbers are particularly useful in
applications that edit video.
A SMTPE time code index is the rarest type of index. It uses SMPTE
time code as the basis of the index and can be used only on streams
that have SMPTE time stamps included with their samples. SMPTE
index is currently not supported. |
