VCM Media Viewer

Previous Next  Print this Topic

The left side of the Media Viewer window is the actual Media Viewer. When the Media Viewer opens, the low resolution proxy video is queued up for viewing (if the proxy video generation was enabled when the video was captured) or the picture selected is displayed. If no low resolution proxy video is available, the original video file is played.

View Video Files

Use the Media Viewer to view videos at different speeds, search metadata content, navigate to a particular point in a file, clip parts of the video for export, and send clips to the Export Queue. It is comprised of the basic controls of any popular video viewer (such as volume, play, stop, skip forward, skip back, beginning, and end) and the following additional controls:

Media Viewer

Timeline

The timeline pointer indicates a part of the displayed video. Click, hold, and drag the pointer either forward or backward in the video. Click to the left of the pointer to rewind the video one second at a time, or click to the right of the pointer to advance the video one second at a time. Click and hold in either direction, and the pointer moves automatically one second at a time.

The number to the left is a time code that indicates where the pointer is in the video (and the part being displayed). The number to the right indicates the total length of the video. The vertical green line to the left indicates where a clip begins, and the vertical green line to the right indicates where a clip ends. Only the segment of video between the vertical green lines will be exported. By default, the lines mark the beginning and the end of the video; they can be adjusted using the scissor buttons.

If you set the beginning of the clip to within one second of the beginning of the file and one second of the end of the file, the entire original full resolution file is exported.

Some video includes an embedded time display, or time code, that assigns a number to each video frame of video. This is indicated by a golden triangle in the timeline. Click the triangle to select an embedded time display option.

Scissors

Use the scissor buttons to select clips from the video. Numbers indicate beginning and ending times. Click the left button to denote the beginning of the clip, and the right button to denote the end of the clip. You can repeat this process to export as many clips from a video as you need; this creates multiple clips from a single file. However, before selecting and exporting a second clip, you need to add the currently selected clip to the export queue by clicking the Export button on the main Media Viewer window.

Jog Shuttle and Playback Speed

Use the Jog shuttle (when available it is the control on the left), to fast forward or fast reverse the video clip. Click, drag, and hold the orange control to the left to rewind, or to the right to fast forward. Use the control on the right, Playback speed, to run the video faster or slower. Drag the orange control left to play more slowly or right to play more quickly.

Search box

Use the Search box (when available) to find content from associated video metadata in stored video.

Type a term in the Search text box, and then click the Search button to find the term in the video. For example, if closed captioning metadata is saved with a video file, and it contains the word "fabulous", then the video advances to two seconds before where "fabulous" appears. If "fabulous" is not in the metadata, it will not be found even if it occurs in the audio.

Content searching is supported and you can use wildcards, but only if a video script file has been ingested with the video.
Closed captioning text may be extracted from mpeg-2 video files if it exists in the picture user data as defined in the EIA-708 standard.

Storyboard

The Storyboard strip at the bottom of the Media Viewer displays still images taken from the video file at regular intervals. It provides a visual representation of the video file contents and an easy way to quickly see and navigate to a point of interest in the video. Use the horizontal scrollbar to scroll through the frames. As you move your mouse over an image, the time associated with the image is displayed (by default, at one-minute intervals). Click an image to jump to that point in the video. Note that the pointer jumps to the corresponding point on the timeline.

The time interval parameter can be changed in the VCM User Preferences.
