This reference guide is for both the Clip Preview pane and the Sequence Preview Pane. Note that there are differences between each pane's appearance and functionality. The Clip Preview pane is pictured below.

  1. Title Bar

    Shows the name of the selected clip / sequence. Clips can be renamed in the clip bins only, either from the right-click menu or from the Clip menu.

  2. Preview

    Shows the frame of the clip/sequence at the current playback position. Note that previews use a resolution which may be lower quality than the final video. Please save the sequence as a video to see the final quality.

    Clip Preview resolution
    For the Clip Preview, the selected clip will be displayed at its original aspect ratio and at a limited resolution. If you want better quality/resolution you should switch to Full Screen preview by using the Maximize button.

    Sequence Preview resolution
    The Sequence Preview's aspect ratio can be manually selected and the clips on the sequence will be letterboxed or pillarboxed to meet that aspect ratio. However, you will likely want to keep it on the default setting, Match Content which will smartly detect the aspect ratios of the clips on the sequence and change the sequence preview size to match. If, for example, there are 4:3 clips and 16:9 clips on the sequence, the Match Content algorithm will pick the ratio that has a greater combined length on the sequence.
    The Match Monitor option will match sequence preview display aspect ratio with the aspect ratio of your monitor.

    If the preview is played in a region that has not been cached yet, and frames cannot be rendered in real time, a message may be shown here in place of the preview.

    Right-click on the preview for a context menu:

    Show Previous and Next Frames
    When checked, the previous, current, and next frames are shown side by side. Click on the previous or next frame to seek to that frame.

    Use This Frame for Thumb Frame
    If the selected clip is in a clip bin, this changes the frame shown in the clip bin in thumbnail view. If the selected clip is on a sequence, this changes the thumb frame shown when the sequence is in Storyboard mode.

    Widescreen Aspect Ratio Fit
    This changes the aspect ratio output of the clip.

    Take Snapshot of Clip
    Saves the frame from the current preview position to an image file, and adds it to the Images clip bin. When you click the dropdown menu, a prompt will appear asking you for the resolution at which to capture the snapshot. More information about the available resolution options can be found at http://www.nch.com.au/kb/10231.html.
