Notes

Video files can be annotated using notes. Media-related info can also be displayed using notes.

Notes are text boxes placed in video windows for labeling items, describing trends, and relating additional video information. There is no limit to the number of lines a note can contain. Click the expansion button, , to enlarge the window.

Click Apply to process any Templex statements contained in the note and display the text in the note box or to update existing text.

Note List

The note list displays the names of all the notes in the active window.

Select a note from the note list or click on a note box in the window to edit it. Notes can be renamed, added, cut, copied, and pasted using the note list controls.

See the Templex Reference for complete descriptions of the Templex statements and more information on writing Templex templates.

See Math Reference for more information on math and string functions and operators.

MediaInfo Note

MediaInfo Note is a type of note that will be displayed by default after loading any video file. It contains the current time of the video. This note can be modified, hidden, or moved but it cannot be deleted.

Templex Statements in Notes

Notes can contain Templex statements as well as math and string functions and operators just like HyperView or HyperGraph. Templex enables you to include text from an external file, call external functions, assign variables, and perform math operations within a note.

See Templex Reference for complete descriptions of the Templex statements and for more information on writing Templex templates.

Note: See Math Reference for more information on math and string functions and operators.

Below the note text box are six buttons that represent Templex variables that can be included in a note. For example, if a note contains the variables {mediatime}, {frameindex}, and {filename}, then the current playback time of the video, current frame index, and the name of the media file are displayed in the note. This note always refers to the current, active media in the window.

{filename}: Displays the name of the media file.
{filepath}: Displays the full file path of the media file.
{mediatime}: Displays the time stamp of the current frame inside the video. Media time is calculated after applying scale and offsets for the current video on the page time.
{frameindex}: Displays the current frame number of the active video in the window.
{pagetime}: Displays the absolute time at the animation control bar of the entire page. This is a global time value for the page and it stays consistent across the MediaView windows of the same page.
{amfnote}: AMF Note is a special supplement to the Media Time value that can be added during video creation in the AMF format. AMF Note returns nothing in case the video format is not AMF or if there is nothing stored for AMF note while creating the AMF video.

Note: See Altair Movie Format to learn how to convert a group of images to a video with a user-defined time stamp on each frame.

Other Templex variables that can be included in a note are the ones that take the values from a marker or a measure:

Marker-based: Available output values are name, x, y, t.; For marker1 from page1-window1, a sample syntax would be:; {p1w1marker1.name}; {p1w1marker1.x} and so on for y and t.; Name type output is string-based, while x, y, t are zero-based vectors for coordinates and time values.
Measure-based: Available output values are name, mag, dx, dy, x1, x2, y1, y2, t.; For measure1 from page1-window1, a sample syntax would be:; {p1w1measure1.name}; {p1w1measure 1.dx} and so on for other outputs.; Name type output is string-based, while dx, dy, x1, x2, y1, y2, t are zero-based vectors.

To get a specific value from a vector, the usual index operations can be used.

For example: “p1w1measure1.dx[0]” for the first value from the dx vector of p1w1measure1.
